Final version

On the table on the top right; there should be a note saying under "Release Date(s)" Final Version: November 11, Proof of date: www.spearpointsecuritygroup.com . Also, why is the page locked from editing? Minecraftrules (talk) , 30 April (UTC)

The date is already there. The page is protected due to excessive vandalism. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 30 April (UTC)

Grammar change

The article currently reads "(such as drowning or falling into magma or lava)"

I believe it should say "(such as drowning or falling into lava/magma)"

There is no "Magma" block in Minecraft, although most lava in the game is generated underground, it is simply called "Lava", even though it is technically magma. (talk) , 29 April (UTC)

WP:SLASH is generally not used on Wikipedia. Also see #Lava_vs._Magma above. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 29 April (UTC)

Ok, but i think it should be changed to "(such as drowning or falling into lava or magma)", as "lava" is the primary term for the block in game. (talk) , 4 May (UTC)

It has already been changed. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 4 May (UTC)

Updating main screen picture

I am new to wikipedia. I have a picture of the beta _01 title screen. How would I upload it? —Preceding unsigned comment added by Picklebobdogflog (talk • contribs) , 4 May (UTC)

_01 title screen isn't any different from title screen except for the version number, so I don't think there is any point in uploading it. In any case, you would simply upload a new version at [1]. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 4 May (UTC)

Minor Mistake

The current line "For example, tools, such as axes, shovels, or pickaxes, can be used to chop down trees, dig soil, and mine ores," should be changed to, "For example, tools, such as axes, shovels, or pickaxes, can effectively be used to chop down trees, dig soil, and mine ores respectively." —Preceding unsigned comment added by Sebastian (talk • contribs) , 1 May (UTC)

Done! Croben^Problem? , 6 May (UTC)

Current version

Although I agree it is not necessary to put the patch number in the version piece of the infobox, it may be useful to mention that the server is in Beta patch fix 2 and the client is in Beta patchfix 1. We could insert this somewhere in the meat of the article where it wouldn't clog up the infobox. Picklebobdogflog (talk) , 4 May (UTC)

The typical consensus was to not as previously, the game would have been updated several times, causing us to have to update the article just as often. I guess I like what you've done though. ^Jguy_Talk^Done , 8 May (UTC)

Is it really in _02 already?

Crafting

This is my opinion, but I think the main article should include the crafting part of Minecraft or at least link it to the crafting site. What is your guys input on that.— Preceding unsigned comment added by IChangeAll (talk • contribs) , 13 June (UTC)

Mostly gaming cruft and not suitable for the article. The article will get you to www.spearpointsecuritygroup.com, which links to the minecraft wiki as a resource there. Seems like that's enough to me. ferret (talk) , 13 June (UTC)

(edit conflict) This has been discussed before and Wikipedia is not a WP:GAMEGUIDE. Crafting recipes would be inappropriate. We also already have a link to Minecraft Wiki. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 13 June (UTC)

Mentioning the Current state of the Nether

This is not really an important thing, but i do know that most Minecraft players know that the Nether is not properly in Vanilla multiplayer. Notch has stated he will add it in Version , I think this should at least be given a brief mention in the article, or have it say something like "Although introduced in Beta , The Nether was not properly added to multiplayer untill the update." (talk) , 9 May (UTC)

Oops, it is protected. I'll add it for you. ^Jguy_Talk^Done , 10 May (UTC)

I'd have to disagree on the "it'll be in " bit. Articles shouldn't speculate on future events; see WP:CRYSTAL. Other than that I have no objections. elektrikSHOOS , 10 May (UTC)

A lot of this article is approaching the far side of WP:GAMECRUFTy scale. Converted the caption to "A screenshot of "The Nether", an alternate dimension that Persson added in Minecraft single-player Alpha version " This is very marginally helpful to understand the game. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 10 May (UTC)

@Elektrik Shoos, it is NOT www.spearpointsecuritygroup.com if you don't play Minecraft it's understandable. He announced it to the public a few days ago. Please do research before saying something. www.spearpointsecuritygroup.com . Minecraftrules (talk) , 11 May (UTC)

saying that notch announced it isn't the same as saying it will happen. to provide an example, i'm pretty sure the mod API was announced as being introduced in , and it wasn't. things tend to slip or not make deadline. this is the nature of software development. Kaini (talk) , 11 May (UTC)

Future events are acceptable if they are notable and published by reliable third-party sources. Expected feature updates are not an encyclopaedic material to a general reader unless they convey important information. Same was true for wolves/biomes/Nether/etc. and is true for maps/pistons/etc. It is mentioned several times in the article that the game is constantly updated. The specifics of the features are only relevant to the players/fans. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 11 May (UTC)

I do, in fact, play Minecraft, probably a bit too much for my own good. I also follow Notch's tumblelog and read it regularly. That said, see what the above users wrote, as it sums up what I was going to say rather nicely. elektrikSHOOS , 11 May (UTC)

I have new proof! [2][3]Minecraftrules (talk) , 23 May (UTC)

The image of the nether only mentions that it was added in single player, not multiplayer. Daedalus (talk) , 12 June (UTC)

this is in refrence to an earlier point raised in the section. the mod API is slated for release as part of patch where the current patch is _ for simplicities sake the first zero has been thus far removed from all official releases and has been replaced with the version sign beta. never the less the way i have described it is the correct method of version numbering in computer games as designated by the majority of game developers. — Preceding unsigned comment added by Ryukage19 (talk • contribs) , 1 July (UTC)

An Editor placed "Patch Versions" In the infobox

Is this a good idea? I'm not against it, personally. However, consensus was that fix versions should not be the Version number. I was wondering if this was acceptable, due to it being in a collapsible list. Is this acceptable, or should it be removed? Croben^Problem? , 10 May (UTC)

Forgot to mention. The normal version is still there. Just Patch Versions (1.e. _01 for client, _02 for server) Is under it. Croben^Problem? , 10 May (UTC)

It's 3 threads up. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 10 May (UTC)

D'oh. My bad. Croben^Problem? , 10 May (UTC)

Yeah, a collapsible box is an acceptable compromise for the moment. No objections. elektrikSHOOS , 13 May (UTC)

Agreed. in fact i believe it adds a good minor detail to have within the article. if there is any argument later about it my vote is keepRyukage19 (talk) , 1 July (UTC)

Updating the gameplay section

Currently the following is stated: "The game world is procedurally generated as the player explores it."

In truth, the game world is procedurally generated by the random or fixed seed at the time the player creates a new world. The game world is then discovered as the player explores it. Creating a brand new map with the same seed will be generated the same way. Not sure if this text needs to be updated or if that is indeed the proper wording to be used. Thanks. —Preceding unsigned comment added by (talk) , 18 May (UTC)

The current wording is correct. The game does not generate the world until you reach it, but since the "random" generation is based on a fixed seed number, it's the same every time you generate it (for that seed). The actual files that hold the world data are not created until you reach it, so it's generated, not discovered. --PresN , 18 May (UTC)

to be even more specific, the world does not generate a chunk until you reach it (well, can see it), and the chunk is generated on an algorithm which uses the seed value as seed for the pseudorandom number generator which provides the perlin noise which makes the landscape and the caves. Kaini (talk) , 18 May (UTC)

just to add. there is also speculation that the chunks beyond the initial generation are completely random regardless of the world seed. this would mean that when using the same seed only an upper limit of (just a random guess) say 16 chunks are the same. other chunks on the border of these initial chunks are generated to preserve realism between chunk boundaries (hightmaps, cave locations, etc) but beyond maintaining that realism the chunks generate randomly.(idiot proofing) please note this is pure speculations and has not been proven through any process. this was mentioned just because i find the idea interesting (/idiot proofing) Ryukage19 (talk) , 1 July (UTC)

It's not random, but might seem so at extreme values based on software/hardware. In essence, the terrain formula starts to produce "wrong" values mostly as floating point numbers reach high values and lose precision. But this is a non-talk page tangent that's pointless without reliable sources because WP does not speculate. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 1 July (UTC)

Xperia

I almost did this myself but decided to bring it up here. Other than mentioning that the Xperia will have a limited exclusive early release, why is it listed as a separate platform in several places in relation to Android? Xperia is an Android system. Unless someone has a compelling argument, I'll be removing Xperia from platform lists and leaving only a note that it will have an early release amongst other Android devices. ferret (talk) , 7 June (UTC)

I was confused by that, myself, considering that the Xperia Play will be running Android, and listing it separately seems redundant. Your solution seems more appropriate. elektrikSHOOS , 7 June (UTC)

I think this is a valid point, and I also noticed that Android, iOS nor Xperia was on the platforms list, and I know it's not because it is unreleased because the Xbox is also unreleased. Somebody fix this. --WinCamXP (talk) , 15 June (UTC)

the issue with Xperia and other android systems is that the Xperia platform will be allowed access to Minecraft Mobile EARLY compared to other android systems. best speculation says this exclusivity will last about a year before other android systems are allowed www.spearpointsecuritygroup.come19 (talk) , 1 July (UTC)

Games for Windows

The game will be released for and features cross-platform play. The games is on which means Xbox Live support. The Windows version would then need Games for Windows LIVE for cross-platform connection. I put this game as a Games for Windows certified title. SYSS Mouse (talk) , 18 June (UTC)

It's not really a "Windows" game, as platform is Java. Also Category:Games for Windows certified games is a sub-subcategory of Category:Windows games already, so even if it were a Windows game, it wouldn't fit. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 18 June (UTC)

That also reads as a long string of OR. Would definitely need a source stating such a major change in platform compatibility. ferret (talk) , 20 June (UTC)

Note also that Games for Windows is a certification, and Games for Windows Live is that cert + being hooked into Live. Right now, it is neither of those things, and while it will almost certainly have to be Live certified for multiplayer across to the Xbox, it's not right now, and so shouldn't be in the category. --PresN , 20 June (UTC)

Question. We do list platform categories for upcoming games. What about expansions/ports/conversions of existing games covered on the same page, do we add the upcoming platform categories? Logically, I would say no? —&#;&#;HELLKNOWZ&#;&#;▎TALK , 20 June (UTC)

I don't think it should, no. Articles probably should be in "[platform] games" until they're released to start with, but we do it anyway as the alternative is nothing. Here, Minecraft is already in the PC cat, so we don't need to add cats for its unreleased ports. --PresN , 20 June (UTC)

PresN, I find your logic is faulty. First of all, other ports, even the unreleased one, is mentioned in the article body and/or infobox. Thus it seems contradictary of mentioning it in article but not in categories. WP:Crystal does not apply here since the upcoming games has reliable sources. SYSS Mouse (talk) , 21 June (UTC)

Categories (and infobox) represent the subject of an article; whereas mentions in prose clearly identify the upcoming ports separately. So categorizing the page means categorizing the subject. But in this case the subject, i.e. Minecraft, is not yet an Xbox game. We should not add categories pre-emptively. After all, you would not add Category deaths even if reliable sources reported John Smithy (serial killer) is to be executed in October (pardon the example). —&#;&#;HELLKNOWZ&#;&#;▎TALK , 21 June (UTC)

There is also the issue with subject matter when pre reporting future events in anythings history. of course human deaths is one where you wouldn't want to touch until after the fact. but you could argue that adding ports of a game before hand adds to an articleRyukage19 (talk) , 1 July (UTC)

massive string of minor updates

i apologize for the string of minor updates i had to make. i was having issues getting a reference tag to work and the preview button wouldn't display any form of error until i hit save page. The issue has been fixed as of this time Ryukage19 (talk) , 1 July (UTC)

Minecraft for iOS

Could someone with edit rights correct the name of the iOS/Android developer (if it's relevant info at all), the surname is Nieminen, not Neiminen. See www.spearpointsecuritygroup.com— Preceding unsigned comment added by (talk) , 7 July (UTC)

Done. Thanks for the catch. ^Jguy_Talk^Done , 7 July (UTC)

possible way to show future platforms

in the issue of adding future unreleased platforms i think ive figured out a way that will be aggreable to both sides of the argument. an edited platforms section of the info box with the edits has been provided as part of this section:

disclaimer:please note the info box doesn't work in discussion so the code would have to be debugged prior to posting on the article. some crucial parts of the code have been removed due to bugs when interacting with the discussion page environment.

You mean like so: —&#;&#;HELLKNOWZ&#;&#;▎TALK , 1 July (UTC)

thanks for the fix. my HTML skills suck Ryukage19 (talk) , 2 July (UTC)

I still fail to understand why Xperia, an Android device, is being listed separately from Android. It's getting an early release, sure, but it's not a separate game entirely, nor is it even a separate build. elektrikSHOOS (talk) , 8 July (UTC)

It shouldn't be listed. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 8 July (UTC)

The following content could be added initially in the introduction or Gameplay section:-

Minecraft is based on the client-server model. The server can be hosted on all the major operating systems that are available today - like Windows, Mac OS X and LINUX. ^[1] There is compatibility with most of the LINUX flavors, such as Debian^[2], Ubuntu^[3], CentOS^[4] and others.

Tnayakm (talk) , 12 August (UTC)

Neither of these references is reliable though; these are both how-to guides. User-edited Wikis or personal blogs are not suitable to support facts in an article. Concluding that the game is compatible from these is original research. Besides, it's not the game that is compatible with those OSes, it's Java. And listing Linux flavours over Windows or OS X is undue weight. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 12 August (UTC)

Picture showing randomly generated landscape

I think the text under that picture needs to be changed. As we all know the landscape is not randomly generated. Only the seed is a "Pseudo Random" number, but provided with the same seed, the landscape is always the same. So the generation of it is not random (talk) , 18 July (UTC)

It is "random" for the end-user observer and anyone trying to predict what the landscape will look like. While the terrain can be recreated with the same seed, so could any computational random process that uses a seed. The only difference is that Minecraft lets the player choose this seed. See Random#Randomness versus unpredictability. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 18 July (UTC)

The anonymous poster doesn't appear to have confused randomness with unpredictability; rather, they seem to be making the point that as Minecraft's level are not truly random but pseudo random (what you described as "computationally random"), then it would be better to describe them as such. Perhaps this could be done along with a link to the article on Pseudorandomness? Aawood (talk) , 18 July (UTC)

My point was that in generic computer science-related articles "random" can be used in place of "pseudo-random", since deterministic vs. non-deterministic nature of random generators is trivial to the end-user. For the purposes of the screenshot, it is random and no end-user could have guessed what it would look like. Same way we don't clarify "generated" is "computer software generated" or "landscape" is "virtual landscape". —&#;&#;HELLKNOWZ&#;&#;▎TALK , 18 July (UTC)

&#;Done —&#;&#;HELLKNOWZ&#;&#;▎TALK , 18 July (UTC)

I changed the text, but realized the game actually lets you set the seed for the level generation.. So it might actually be relevant information. – Acdx(talk) , 12 August (UTC)

Edit request from D3ath1id3r, 14 August

This edit request has been answered. Set the or parameter to no to reactivate your request.

Hi, why not adding a sub-section "See also" which features Minecaft-likes?

For example:

Lots of other games on Wikipedia have such section. This would help linking these games together and be more consistent with Wikipedia itself, IMO.

Greetings, DR

D3ath1id3r (talk) , 14 August (UTC)

Partly done: Linking to Manic Digger and Mythruna would be inappropriate as they have no pages on Wikipedia, and linking to them would violate our external links policy. www.spearpointsecuritygroup.com is currently tagged for deletion so I'm inclined not to add a link until we see a resolution for that tagging. However, linking to Ace of Spaces is valid, so I'm adding that now. elektrikSHOOS (talk) , 15 August (UTC)

TNT

" in Classic mode, TNT will act like any other block and break when hit, but, in Beta mode, TNT will detonate after the fuse is lit." Should be changed to: " in Classic mode, TNT will act like any other block and break when hit, but, in Beta mode, TNT will detonate after it is powered."

or something similar as TNT no longer detonates when you hit it, you just get the block back. Avpover (talk) , 16 August (UTC)

I actually typed that part. Anyway, it doesn't say anything about hitting the block, it just says the fuse needs to be lit. (OK, sign it correctly, for once.) PR0T05T33L , 17 August (UTC)

Please Explain what This Game is About

I watched a couple brief YouTube tutorials, read this article, and I still have no clear idea what the game is about. The article has a lot about the development of the game and the platforms it runs on, but practially nothing on what the goals are, what the rules are, what objects can be created, what qualifies as success or failure, how multiplayer differs from single player, etc. As it stands, the article is basically an overview for readers who are already familiar it. See the Civilization IV Gameplay and Technologies sections for a general idea of improvements. (Although that article is still obscure for readers who aren't familiar with the subject.) (talk) , 5 August (UTC)

i'd recommend looking at this archived discussion thread. Kaini (talk) , 5 August (UTC)

Just added two sentences to the article to answer some of you questions- i.e. there are no defined goals, you cannot win or lose, and multiplayer is the same as singleplayer, but with more than one person in a world. As to more detailed gameplay descriptions like what you can make I'm not going to bother; the release is likely to revamp a large portion of the gameplay and would require a rewrite of the section anyway. --PresN , 5 August (UTC)

kk, thanks for the answers, and the URL reference to previous discussion. I've now been playing Minecraft for a week, reading the Minecraft forum, and considering why I'm playing.

The article really needs to state basically what new users and people completely unfamiliar with Minecraft -- who will never use it -- need to know, in an encyclopedic sense.

The goal of the game is to explore, to mine, and to build, while avoiding being killed by NPCs that have no goal, except to kill the player.

However to avoid death the player has the ability to build tools such as swords and arrows to kill the monsters. also tools such as pickaxes and shovels can be made so that the player can more easily mine for resources. — Preceding unsigned comment added by (talk) , 18 August (UTC)

Certainly to be mentioned is that the game physics are not intended to closely match reality, but have internal, consistent manifestions that the player comes to terms with.

along with the single player version is the multiplayer game in wich players connect to servers and build or fight with people arround the world. This is an interesting edition to the game and gives players who have finished or become bored with the single player version to still enjoy the game. However due to the large number of servers operating at once players will often experience lag (meaning the frame rate has slowed down) or the server will disconnect for a period of time. — Preceding unsigned comment added by (talk) , 18 August (UTC)

There are a large number of mods and maps and so on, and while these features are primarily for advanced players, but apparently many who play the game over months (if the forum is any indication) eventually use them. Far moreso than other popular games where a limited group of enthusiasts make changes for one another. As an example, I played Civilization for years before downloading any mod. With Minecraft, if I play an entire month, I certainly will want to look at maps other players have recommended.

Anyhow, just want to keep focus that this is an encyclopedia. Minecraft is a highly successful game that was not developed by one of the major game companies, and this article should try to indicate why, in factual terms, this is so. (talk) , 11 August (UTC)

Edit request for MinecraftCon

This edit request has been answered. Set the or parameter to no to reactivate your request.

Please change the term "MinecraftCon" to "MineCon," as that is the official name of the event based on this website. --Dodge Story (talk) , 20 August (UTC)

Done and more; I've updated and fleshed out the entire section to include information from yesterday's release. (See here.) —JeevanJones (talk) , 21 August (UTC)

Work on Development section?

Reading through the Development section of the article, it read like something that had been appended gradually over the last few years. I wonder if it may be worth actually charting when features were added to Minecraft, with perhaps subheadings of "Classic", "Indev", "Alpha", "Beta" etc.? It could include the addition of employees as the current section does, as well. Obviously it will need to avoid repeating what the Gameplay section says.

Such a rewrite could make it infinitely easier to read, and may be very useful to casual readers who are interested in the development phases of the game as it was created, and at the very least more informative than the haphazard way it is now.

Are there any users out there who would be interested in working with me to find sources and rewrite the section? Pages such as this would be a good start. —JeevanJones (talk) , 2 September (UTC)

Mobs?

Should we call them mobs? I know there is a link, but would a nongamer understand what was meant? Why not call them monsters instead? P.S. I am new so if this has been discussed before or I have offended someone I apologize. — Preceding unsigned comment added by Winfredtheforth (talk • contribs) , 31 August (UTC)

&#;Done. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 31 August (UTC)

Well, it's tricky. You can refer to the menagerie of beasts in Minecraft as "monsters," but they're referred to by the developers, and several outside sources, as "mobs." This probably should be clarified. elektrikSHOOS^(alt) (talk) , 31 August (UTC)

Usually, we avoid jargon if it can be explained plainly; VG articles are probably the worst after maths. How would you explain it without breaking prose? —&#;&#;HELLKNOWZ&#;&#;▎TALK , 31 August (UTC)

I'll look at the passage and try to figure out a way to phrase it that isn't awkward. elektrikSHOOS^(alt) (talk) , 31 August (UTC)

Alright, I've taken a stab at it. elektrikSHOOS^(alt) (talk) , 31 August (UTC)

That's the problem with video game articles. If you explain "mob" in such detail, then so should other terms be explained, like "health bar" and "spawn point". —&#;&#;HELLKNOWZ&#;&#;▎TALK , 31 August (UTC)

Isn't there a page about 'mobs' and what it means in games? PR0T05T33L , 31 August (UTC) — Preceding unsigned comment added by PR0T05T33L (talk • contribs)

Well, I'm making an assumption that the average reader would know what a health bar or spawn point is, as those are phrases commonly used both in development and in games themselves. "Mob," however, tends to be a bit more development-side, since most games refer to in-game creatures as a game-specific term, or generic. Since, at least in this case, the word "mob" has been used both by sources affiliated with Minecraft and outside sources in referring to the creatures in the game, it seems pertinent to use the word in the article.

PR0T0T33L, there is a Wiki page for the phrase. See Mob (gaming). elektrikSHOOS (talk) , 1 September (UTC)

I also fail to see how "referred to as mobs" is detailed. It's a wikilinked mention in passing, and the rest of the paragraph uses "animals," "monsters" or "creatures." elektrikSHOOS (talk) , 1 September (UTC)

I refer to the Pigs, Sheep, Cows, Chickens, Wolves and Squids collectivly as "Animals". and the Zombie, Skeleton, Spider, Spider Jockey, Creeper, Zombie Pigman and Ghast as "Monsters". (talk) , 2 September (UTC)

Survival genre

What is "survival" genre? There is survival horror, but Minecraft is not it. Minecraft's Survival mode is not a genre. Is there a reliable source supporting this claim? I can see quotes like "The current version of Minecraft revolves around one simple principal, survival." but they don't call it a genre. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 12 July (UTC)

Minecraft is a sandbox game. ~Aidoboy — Preceding unsigned comment added by (talk • contribs) , 3 September (UTC)

From the Survival Horror page, such games "make the player vulnerable by providing them with less ammunition and fewer heavy weapons than other action games. Although combat can be a part of the gameplay, the player is in various ways made to feel less powerful than in typical action games, because of limited ammunition, health, speed, or other limitations." This is exactly the style of Minecraft on SSP. LWG^talk , 4 September (UTC)

Without a reference this remains original research. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 5 September (UTC)

Notability of "icons"

I looked at the page, and noticed there isn't a single reference to the notability of community icons. Creepers, for one, are iconic in Minecraft. Without creepers, Minecraft would be a much worse game. Yet, the word "Creeper" is only mentioned once. Aside from that, there are two other characters I believe should be given notability. Specifically, "Rana" and "Herobrine". Both are prominent figures within the community, although Rana has faded into obscurity somewhat.

Rana appeared in an early beta, but was removed due to the artist not responding fast enough. The game looked vastly different and supported smoother blocky creatures. Rana's removal caused a small uproar upon her removal, and many still want Rana back in minecraft. Some going to lengths to mod her back in. After his slow rise to infamy, Mojang themself use Herobrine often as a form of viral baiting. He has been mentioned in official changelogs as being removed three times in a row, and has appeared in both the Wedding Weekend and Minecon promo images.

I'm not saying they should have three paragraphs. this isn't a wiki on everything Minecraft, and as a MCwiki mod, I % would not want that either. but not one sentence on any notable figures adding to Minecraft's viral popularity seems wrong. --Kizzycocoa (talk) , 5 September (UTC)

That's all valid information, but requires proper sourcing. So far, no one has added it yet. It's usually much easier to work from sources to information, not the other way around. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 5 September (UTC)

Both Rana and Herobrine have pages on the Minecraft wiki. Rana is not sourced well, but Herobrine includes lots of sourced and linked information on that page.

For rana, there are some sources. This shows that they even existed. the popularity has faded away, as I said before, so that point would be somewhat harder to prove. However, Herobrine has quite the following. There are countless youtube videos about him, as well as mods, fanclubs and many other things. This sums him up quite nicely, with further sources at the bottom of the page. If any other sources are needed, I could find them.

As for creepers, I see no reason why it cannot be stated the creeper's "ssssssssssss" and appearance is iconic without source. Unless a source is really needed, but it's a universal thing. No-one writes about it, as it's just there. --Kizzycocoa (talk) , 5 September (UTC)

I think creeper should be mentioned in the article. Maybe the easiest way would be to refer to the merchandising where creeper are clearly represented. --Anneyh (talk) , 5 September (UTC)

The notability is a bit debatable, IMO. However, be bold and see what you can draft with credible citations. —JeevanJones (talk) , 6 September (UTC)

It's not just about "sourcing", but about reliable, secondary sources. Primary sources (Persson/videos) can only be used without any interpretation/original research and from neutral point of view (not covering material used for promotion/advertising). Forums and Wikis are unreliable as they are user-edited. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 6 September (UTC)

ok, I will get to work on drafting the small changes with citations.

I must personally state thought, this is a wiki, so is it unreliable? just wanted to state the oxymoron of a wiki that needs citations, but isn't citable itself. :P

ok, I'll see what I can come up with! --Kizzycocoa (talk) , 6 September (UTC)

Well, disclaimer makes no pretence of reliability: "Please be advised that nothing found here has necessarily been reviewed by people with the expertise required to provide you with complete, accurate or reliable information." I guess it is sort of an oxymoron, however "citing reliably" principle does not require "being reliable". —&#;&#;HELLKNOWZ&#;&#;▎TALK , 6 September (UTC)

(edit conflicted) I see what you mean, but don't feel adverse to using other Wikis to get the sources they cite. For instance, if someone's using Wikipedia for their research, they wouldn't (usually!) say "from Wikipedia", but would pick out applicable sources from the references section, and use the information from those. At the end of the day, Wikipedia is built on its sources. —JeevanJones (talk) , 6 September (UTC)

ModDB awards

thought I'd just mention this too. A while back (almost a year. wow, time flies), Minecraft was entered in many awards on ModDB. which, as wikipedia says, "gained the reputation of the biggest game modification related website on the Internet". So, I think it should be noted somewhere.

the main prize-based award for indies, "Players Choice - Indie of the Year", went to Minecraft. nothing is known of how they used the prizes, as they did not wish to go on Desura, and the other smaller awards weren't mentioned by Mojang. Minecraft also won two smaller non-prize awards. the "Editors Choice - Most Innovative" and the "Editors Choice - Best Singleplayer Indie". it basically won 3/7 awards in the Indie category, one being the top-prize award. the very minor awards were not ranked, but praised the "best developers", and "best advertising campaign". that being Mojang and the Cake campaign respectively.

for all sourcing, here is the list of award articles.

it's also notable that, since, and even sometime before the awards, Minecraft has been ranked #1 constantly, only falling back to #2 occasionally, but always creeping back up to #1 again. ranks can be seen here, on the right under "popular games". at time of typing, it is #2 due to the recent Project Zomboid update, but likely will creep up once more. so, I think the awards, and perhaps the constant high ranking, should be mentioned in the Reception section. --Kizzycocoa (talk) , 6 September (UTC)

It already says "Indie DB awarded the game the "Indie of the Year" award as chosen by voters, in addition to two out of five Editor's Choice awards for "Most Innovative" and "Best Singleplayer Indie".[47]" in the article. —&#;&#;HELLKNOWZ&#;&#;▎TALK , 6 September (UTC)

wait, what?

aaaaaaaah. I see. I did read through that, but didn't go further than december. my mind just read it as "after december". plus, I was looking for ModDB, and didn't see that. it doesn't help when they're all in a block too.

my mistake. nevermind then! ^^ --Kizzycocoa (talk) , 6 September (UTC)

Edit request from , 8 September

This edit request has been answered. Set the or parameter to no to reactivate your request.

There are a few little things not clear in the article.

1. When dying, the player is not necessarily brought to the starting spawn point, since Beds have been brought into the game (Beta version). Beds will set your spawn point, but not your STARTING spawn point, where you will appear if you die after happening to break the www.spearpointsecuritygroup.comnce: www.spearpointsecuritygroup.com#!/jeb_/status/ and www.spearpointsecuritygroup.com

Therefore: "Upon dying, items in the player's inventory are dropped and the player is teleported to the starting spawn point." should be "Upon dying, items in the player's inventory are dropped and the player is teleported to the starting spawn point or the bed last slept in."

2. It is not in the article that dropped items burn in lava, or that materials can burn. Reference: www.spearpointsecuritygroup.com

Therefore: "Lava, which, as mentioned before, drains life, is dangerous in another way: certain materials, like wood and wool, can burn, and dropped items will disappear." should be added.

3. The article fails to tell about the unique crafting system in which the shape of the desired item is formed to create it. Reference: www.spearpointsecuritygroup.com

Therefore: "weapons, armor, food, and various other items." should be "weapons, armor, food, and various other items in a unique way by arranging the materials in the shape of the object."

These are small changes and it is not needed to use many words for them, but I actually DO miss them in the article. If the reference is not enough, well, just play Minecraft and you'll see.

I went ahead and fixed the thing about spawning, since the existing version was unclear. The other two items are somewhat trivial and are not necessarily important enough to justify mention. I will let an editor who is more heavily involved with this article make the call on them. LWG^talk , 8 September (UTC)

Mechanics[edit]

As of yet, there are a few theorys as to how these things work. I am somewhat new to wikis, so I probably shouldnt have dumped a theory in the page. Shall we post them here? Lugnut , 22 February (UTC)

I have double checked that the same seed results in the same map. The spawn is different though, otherwise the seed is pretty much www.spearpointsecuritygroup.comzzard , 22 February (UTC)

www.spearpointsecuritygroup.com

The seed number is used by the random number generator to make a sequence of "random" numbers to generate a "random" map. So using the same seed number should always generate the same map. I think the first random number generator took the middle four digits of a six-digit number and squared it to get the next number (or something like that)PurpleKiwi , 22 February (UTC)

I've been testing out different seeds from the infamous , l33t, Notch, 4, 1. None of these produce the same results as what I was told I would receive. All very standard worlds with a few "landmarks" of sorts but nothing like I was told to expect. Try using a 19 digit seed and see if those produce similar results so there won't be any random digits added since you filled the field. MDR , 22 February (UTC)

I thought the same thing, but when i generate the map "1" a few times, i noticed the spawn moves and theres a sand + sign landmark thats a good marker. The map is the same in theory, but i think there are minor changes including trees, sand (if it moves?), mobs etc Lordhazzard , 22 February (UTC)

Also i think to make things a lot easier, it would be good for players to goto x:0 and z:0 of the seed they generate and using that as the basis for the map design/layout/shape/biomes Lordhazzard , 22 February (UTC)

Some seeds provide everytime the same map with the same spawn location (like the seed "23"). It's said in the article that the spawn location is generated from the name of the world, but it doesn't work for the seed "23". In fact, if a seed provides a map with a spawn location of x= y= z=, then it will be always the same spawn location if you generate a new map with that seed (like "23" or "Glacier") whatever is the name of the map. But if the spawn is located on other coordinates, then a new generated map with the same seed will be exactly the same, except with another spawn location. That's what I experienced in the game. --Zeteube , 24 February (UTC)

Lock?[edit]

Can someone lock this for now? Most of this is total garbage. All the stuff on specific map features and placements isn't true; these seeds are only general map averages. --Fishrock , 23 February (UTC)

I removed all but 5, which seems like a reasonable number of examples, but it looks like people are just going to keep adding more and more.. Manifold , 23 February (UTC)

Pffft. People. Anyways, I think and probably alter the terrain average, and mixing the numbers probably mixes and/or amplifies the terrain alterations. A-Z might aswell. --Fishrock , 23 February (UTC)

Rename[edit]

I suggest renaming this page to {{static link|Seed (technical)}} (to avoid confusion with Seeds because the current title isn't useful. Is "technical" a good disambiguation for it though? --Gnu32 , 23 February (UTC)

I'd have to say {{static link|Seeds (technical)}} due to that's what it is. IKJames , 23 February (UTC)

Different spawn point every time?[edit]

I'm not entirely convinced about this "different spawn point every time" thing. I tried out a seed on the forum that said that you would spawn in a dungeon, and I did, in fact, spawn in a dungeon.

Was this changed at some point? --Abcorn^talk , 3 April (UTC)

I tested this with a friend- first using notable seeds, such as Glacier and Archimedes, then with random gibberish. Result was % exact spawn. I imagine most of your probs concerning random spawns are related to tiny things like an extra space on the end of seed or a www.spearpointsecuritygroup.com , 8 April (UTC)

Can we get some clarification on how a alphabetic seed is converted to numeric?[edit]

Does anyone know how the www.spearpointsecuritygroup.comde() function actually works?
The article lists the Calculation as "97 * 31**2 + 98 * 31 + 99 = " (for the seed 'abc')
The Java documentation lists the formula for calculating hash codes as:
s[0]*31^(n-1) + s[1]*31^(n-2) + + s[n-1]
(where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation)
I'm confused, these two examples seems to differ from each other. Help? Superbun , 12 April (UTC)

I see no contradiction. s = the string, s[i] equals the character in the string, n = the length of the string. The string position is zero-indexed, so the count starts at zero. Going by the example above:

s = "abc"

n = 3

s[0] = 'a'. ASCII code of 'a' =

97 * (31 ^ (n - 1))

97 * (31 ^ (2))

97 * =

s[1] = 'b'. ASCII code of 'b' =

98 * (31 ^ (n - 2))

98 * (31 ^ 1)

98 * 31 =

s[2] = 'c'. ASCII code of 'c' =

99 * (31 ^ (n - 3))

99 * (31 ^ 0)

99 * 1 = 99

Discussion[edit]

My Opinion is as follows: Why I understand that the selection of interesting Seeds is subjective, I’d recommend to include Screenshots of some. While this is subjective, too, we have example screenies everywhere, so nobody could be opposed to that solution.

Regarding Fansites; I think they have their place here. Don’t think so? Would you kindly click on the Arrow next to “Minecraft” in the main site bar on the left? Fansite links are even there. We are all a community, everyone who doesn’t agree is free to leave.

Conclusion: If nobody has good reasons against my suggestions, I will carry them out in a few days. Revertings of this edit without a good reason will be reported and the reverter will be punkished for vandalism. ‒Flying sheep , 12 April (UTC)

I don't agree with putting interesting seeds on the page itself. Links to fansites dedicated to seeds, absolutely, but I don't think individual seeds have their place here. Just my opinion. --Abcorn^talk , 12 April (UTC)

Whenever we allow fansites, we just have people revert warring over them. –User:Ultradude25^{(User:Ultradude25/t|User:Ultradude25/c)} at , 13 April (UTC)

That's exactly how it was before, but people still did it up until the point where they earned themselves a block. –User:Ultradude25^{(User:Ultradude25/t|User:Ultradude25/c)} at , 13 April (UTC)

Okay, here's a couple more ideas:

• Put them back and put a comment like <!-- Don't remove these! -->, or
• Put them on a subpage like {{static link|Random seed/Fansites}} --Abcorn^talk , 13 April (UTC)

@Abcorn: Of course, a listing of individual seeds is too subjective. It would be educational, however, to post a screenshot of e.g. , which proves that you can spawn inside a dungeon, … As previously said; screenshots are there to illustrate a topic and are subjective per definitionem. So we could use them for interesting seeds.

I think we should keep the links like this (or similar)

The only objection I have is the link to the random seed reader.

Link to my seed reader?[edit]

Just wondering if you guys think it'd be ok for me to add a link on this page to my seed reader: www.spearpointsecuritygroup.com

I have no problem with you providing a link under External links. It appears what you are offering is different than what is there. However, remember that this is not an advertising service. A single link as an assist to the community is fine, but as noted above, any revert warring will result in a loss of editing privileges. --WynthystImage:User Wynthyst sig www.spearpointsecuritygroup.com talk , 14 April (UTC)

Understood. If someone objects to the addition, I'll remove it. I had a link to this up before, but it was removed during the fansite update war. The reason given was that the original link I provided was a direct link to the JAR file(I didn't have the program on GitHub then). I thought that was a reasonable explanation, as having the direct link on this page would cause a person's browser to ask to download something without knowing much of what it is. With this new link, they get linked to a page with a better description of the program before downloading it. Thedarkfreak , 15 April (UTC)

"no random seed that will give you () entirely desert world."[edit]

Uhm, is it actually correct that it's impossible to obtain a entirely desert world? I mean, unless there is some criteria which somehow prevents such worlds being generated, or biomes exceeding certain size, wouldn't it theoretically be possible, although extremely unlikely to get a world in which only desert biome is generated? –Preceding unsigned comment was added by Mastadi^{(Talk&#;Contribs)} , 21 April Please sign your posts with ~~~~

Worlds are infinite, there's no biome big enough to cover an infinite space. 80% sure they have size limits. –User:Ultradude25^{(User:Ultradude25/t|User:Ultradude25/c)} at , 21 April (UTC)

But wouldn't it be possible to have two (or in this case, infinite amount) biomes of the same kind next to each other, thus appearing like a single big biome? Mastadi , 21 April (UTC)

Well, given how the moisture scale works for biomes I think it's technically possible, but it would be a freak occurrence that such a seed fits inside the seed generation box. I think the comment on the page, while potentially misleading, is accurate enough to be a worthwhile piece of information to someone who doesn't know much about random seeds. --Theothersteve7 , 21 April (UTC)

I have a few questions. 1. There are some programs or mods to change the size of biomes, like desert=99 and tundra=0 means that the desert cover % or something of the map and the other biomes 0,5% of the world (excluding tundra), but does that change the map, for example, if you have plains=99 and the other are 0, does that means that the mountains are removed, or that just the grass, trees and sugercane locations have changed? 2. Also, is it possile to regenerate a floating dungeon (I made one with a zombiepigman spawner with MCedit to scare the pplz on my SMP server). 3. Also, talking about SMP, is it possible to create an seed with enfinite number/symbols/letters, cause I have tried this (#5CDUpskirt&85gx93Yrs~? and it gives a very weird world, but is this bigger then the SSP seed lenght? timmytimmy , 6 July (UTC)

1. That depends entirely on the mod in question, not the MC level generator. If you want to know, you'll have to either download mods and try for yourself, or ask in the appropriate forum threads.
2. I don't think floating dungeons are ever generated by the level generator; I have yet to either hear anything about one, or to see one myself.
3. No.

Relevant info?[edit]

While working through some code for random seeds, I noticed something about the datatypes, that suggests that if you're using strings or phrases for the seeds in worlds, then you'll only be able to access a fraction of the available possibilities for seeds. The reason is, if a string is found in the World Seed entry field, then the Java hashCode() function is used on the string to obtain a unique hash from it. However, this function returns a bit integer(datatype int). The Random number generator's seed is a bit integer(datatype long), and is stored as such in the save file. The other 32 bits seem to get filled with 1s when the int is upscaled to long. Those bits don't change depending on what string is entered.

However, if a numeric seed is entered, or Minecraft is allowed to generate a seed on its own, all 64 bits can be filled with information. Jeb's blog post on the seed generator says that Minecraft uses the current system time to generate a random seed. The most likely function used is www.spearpointsecuritygroup.comtTimeMillis(), which returns a long value, the current system time in milliseconds. This also uses all 64 bits, instead of being restricted to

Using pure numbers, or Minecraft's generation, allows for exponentially more possible worlds. Using a string, you're restricted to 2^32, or about 4 billion possible worlds(4,,, possibilities, to be exact). Now square that number, and that's how many possible worlds that the full 64 bits allows for. (2^64 possibilities, or about 18 quintillion possible worlds(18,,,,,, possibilities, to be exact))

So, I was wondering if information considering this should be added to the article, stating that you won't be able to access as many potential worlds using seeds as you would otherwise. Sorry for the infodump :P -- Thedarkfreak , 26 April (UTC)

Sounds relevant enough to me. Feel free to add it, and in the future remember that it's alright to add this kind of thing right away after you've explained it(if it needs explaining). If it turns out to be unneeded it can always be reverted. -Alphap^{User talk:Alphap~Special:Contributions/Alphap} , 26 April (UTC)

Just a quick note on the above: although the Java data type used allows 2^64 possible values, Java's Class Random only uses 48 bits from the seed, so in fact there are only 2^48 possible worlds, not 2^64 as stated above. That's ,,,, if anyone's really interestedEuryleia , 25 May (UTC)

Ah, I didn't know that. Thanks! -- Thedarkfreak , 28 May (UTC)

Experimenting with Seed logic[edit]

I did a few experiments with worldseeds, writing a java program to try to find the worldseed match based on known outcomes from using it. Example: Slimes only spawn in 10% of all chunks. So, if you know enough chunks that spawn slimes, the theory is that you could can possibly narrow down the seed. Here's what I found out, using a world with 17 known slime chunks.

- It was pretty easy to find my string seeded world, because there are "only" billion or so positive and the same amount of negative numbers. It didn't take long to write the program in Java or to run it against the array of chunks. www.spearpointsecuritygroup.comde() = successful.

- I tried another world creation, noting the system time, and looked to see if it could find my worldseed. While running Random() against long integers to represent the range given by www.spearpointsecuritygroup.comtTimeMillis(), I gave it a range of 10m each way, and let it run. It couldn't find it. That's because it does not use www.spearpointsecuritygroup.comtTimeMillis(), as previously believed. I found that Java's Random() is using nanotime (and some additional uniqueness added to it). What that means is, instead of searching inside a 20 minute range of random possibilities for each second, it's actually needing to be searching 1 billion randoms for each second. (Obviously, I didn't find the seed! I'd have to run the program for days, I think)

- To confirm, I looked at the world generation code using MCP, and confirmed that it used hashCode() for manually entered seeds, and Random() for blank seeds. The slime spawning algorithm was used to match the seeds with the array.

End result: It's quite possible to solve what seed a world is using, if you have enough data to feed it that is dependent on that seed, AND if the world was created with a string as the seed. If it was auto-generated, or numeric beyond a certain range worth searching in not bloody likely! -Flenken–The preceding undated comment was added on , 2 July Please sign your posts with ~~~~

Actually, this may be more feasible than you think. There are trillion possible numeric seeds (2^48). If you had 15 known slime chunk coordinates, you would have enough to reliably determine a single seed (because 10^15 >> 2^48). I just wrote a heavily optimized algorithm in C to validate seeds against a hard-coded list of 15 chunks. Running on my GHz i5 on a single core, it can check 1 billion seeds in 3 seconds. If this was run on all 4 cores simultaneously, it could check the entire seed space in approximately days. If I wrote the code in assembly instead, or found a way to run it in GPU computing, it might be possible to reduce this time even further by another 2 or 3 orders of magnitude , 9 November (UTC)

Random seeds are bit longs, not 48 bits, so the seed space is about 4 orders of magnitude larger than that. Checking everything on your computer would take around 70 years (actually even more, since you'd need 20 slime chunks instead of 15). Even with more optimization, that will take years of CPU time. Feasible if you have access to a server farm, perhaps, but not practical. -- Orthotope , 9 November (UTC)

The seeds are bits long, but as stated above, Java's Random Class, which is what is used, only uses 48 bits of the seed for the generator. Thedarkfreak , 31 January (UTC)

swoop[edit]

Using the seed which should spawn you in/above a dungeon, me and a few friends worked out that the chests will always contain: 3 gunpowder, 1 cocoa beans, 14 string, 2 bread, 2 saddles, 6 iron, and the spawner will be a skeleton spawner, so the contents of spawners and chests are set by the seed. Should it be included in the page or the chest and spawner pages? pxUser:OneshotUser talk:Oneshot, 1 May .

Why was the "Sites dedicated to Minecraft seeds" section removed?[edit]

I re-added it with my last update, because that's the format we agreed on here. Why was it removed, does anyone know?

If anyone has any objections to it, they should bring it up on this page, where we agreed on the format. Thedarkfreak , 2 May (UTC)

It was Drenay, but he didn’t bother to mention a reason yet, so the section stays until he does and his reason is valid. – Flying sheep , 4 May (UTC)

duplicate worlds[edit]

I decided to make a new world, so i deleted my old one and immediately created a new one. They were both random seeds. After exploring a bit, I found the house I had in my old world. Everything about the two duplicate worlds was the exact same, except the spawn point was different and all planted saplings were gone. Has this happened to anyone else? --Joejr50 , 24 May (UTC)

That is very odd. It sounds like the game messed up loading something, and loaded the old world after never actually deleting it. Check your game files, see if the world is still there. If it is, delete it and try again. Check the seed generation page for how seed generation works, and somebody else could probably explain it in more technical terms. Deanm , 24 May (UTC)

There's a bug where the game sometimes fails to delete the files for an old world when it deletes the world. If you create another world with the same name, or a similar enough name that your OS's filesystem puts it in the same folder, you'll end up "resurrecting" the old world rather than creating a brand new one. If you used a different seed, when you start generating new chunks in your world, you'll get some very bizarre results. Worlds in collision --Euryleia , 25 May (UTC)

It happened to me once! I was playing a creative mode game in a pine forest. I ran into a pack of wolves. I wanted to befreind them, but it seemed pointless and no fun. I deleted that game and made a new one, but in survival mode. I killed some skeletons at night and went to find some wolves. I couldn't find any, but when i was just about to get home, a tamed wolf came running up to me. It drowned when i was building a bridge, because it went under it and i didn't know.

Well, it's just that my current favoured world is old and therefore doesnt have dungeons, tall grass, etc. that modern worlds have. And I would want to experience these new Minecraft world changes with this same world without using third party software.

Does this put my username and time sent on here automaticly? –Preceding unsigned comment was added by Teh server^{(Talk&#;Contribs)} , 29 May Please sign your posts with ~~~~

No, you need to write 4 tildes (~). You will need to use a mod to get the world's seed, even if you haven't modified your world at all. Calinou - talk×contribs» , 29 May (UTC)

The two links under 'seed extraction' on the main page will help you get the seed. Either upload your www.spearpointsecuritygroup.com file to the seed reader service at the first link, or download and run the Java tool in the second link, and select your world's name to get the seed. -- Thedarkfreak , 1 June (UTC)

Just wanted to add, depending on how old the world is, the world you regenerate may not look very similar. In particular, if the world is from before the Halloween update(which added Biomes, and drastically changed world generation), then any chunks generated before Biomes will not look anything alike. Minor updates don't change the generation code as much, and will usually result in similar terrain. -- Thedarkfreak , 1 June (UTC)

Seed shorter OR converter[edit]

There is a program that transforms a seed into a word, to make it shorter? --Gil , 7 January (UTC)

There are far more number seeds than those that can be made using hashcode(), that is, letters/anything not a number, meaning you would get misinformantion if you tried to return the numbers to the strings that originally went through hashcode(). Also, very few of the strings would be shorter, even if you could get back to them. NighttimeDriver , 21 January (UTC)

Minecraft version Seed Compatability[edit]

We need a way to track when the minecraft version changes the world generation in a way that will cause a world to be generated differently.

For instance, a minecraft will generate a different world than beta even with the same seed.

The problem is if you update your minecraft server/client and try to reuse a map, you will get biome conflicts as the world generates new biomes that don't blend or match the other previously generated biomes. –Preceding unsigned comment was added by Flandar^{(Talk&#;Contribs)} , 9 January Please sign your posts with ~~~~

All you have to do is look at the changelist from the old version to the new version: if at any point you see anything about map generation (biomes are generated differently, or caves have been tweaked, or new generated features have been added, etc.), it's safe to assume that the change breaks seed compatibility. 「ディノ奴千？！」^{? · ☎ Dinoguy} , 10 January (UTC)

Strange spawn![edit]

For MC , the seed "Rebecca" (without the quotes) spawns the user in this tiny cave underground. There's no exit, and they're gravel in the ceiling that falls all the time, and its pitch black with a water covered floor. How could it spawn me in a cave? Puzzled, Jesse V , 4 March (UTC)

Seed from the old biome code?[edit]

The seed '' appears to me to be from the old biome code. There is a taiga, as well as a desert, and a long, long stretch of the old-fashioned kind of sloping mountain land. I find this world much more fun to explore than it's more modern counterparts, especially the flat-topped, hollow mountain you spawn beside. Check it out and tell me what you think! –Preceding unsigned comment was added by ^(Talk) , 25 March Please sign your posts with ~~~~

If it generates under the current version of Minecraft, it's not from "old biome code". It's just a happy coincidence. Thedarkfreak , 31 January (UTC)

Seeds affecting mob spawns[edit]

Does the seed of the world affect its animal and monster spawning patterns? Like I've heard people say that a particular seed would spawn them nearby a bunch of pigs or cows or something. However, I thought that the spawning of creatures was random, and unrelated to the seed. Jedibob5 , 19 May (UTC)

The mobs spawned when a chunk is first generated are determined by the world seed. After that, it is random. -- Orthotope , 19 May (UTC)

New Seeds For Village Spawn?[edit]

SP and SMP Seed differ?[edit]

I found a great Seed on Singleplayer that I gave to my Fiance so we could use that perfect location I found together. When he enters the Seed on SP then he gets the exact same map but when he enters it in Multiplayer then EVERY TIME it's a DIFFERENT world. We do go to the exact same coordinates every time but it's nowhere near similar. It was a worded Seed so I used the /seed command on SP which gave me a few digits. He then tried this but it again wasn't the same Map. Why is that? Is there something we have to add? Are SP seeds not "compatible" with Multiplayer seeds?

The multiplayer seed has to be set in the www.spearpointsecuritygroup.comties file, and then the world needs to be regenerated. Thedarkfreak , 31 January (UTC)

0 in level generation[edit]

i have two questions about seed. 1: what happens if you use the seed 0, or a seed consisting of just zeroes to generate a world? would it be just a blank world? 2: does the algorithm include division? if so, what happens if the level generator is forced to divide by 0? if nobody can find answers to these questions, then it just goes to show how mysterious 0 is. please look into this for me. –Preceding unsigned comment was added by ^(Talk) , 7 November ‎ (UTC). Please sign your posts with ~~~~

If the seed entered is mathematically equal to zero ("0", "", etc.), a random seed is used, as if you had left the seed field empty. The algorithm for turning non-numeric seeds into numbers is documented in the Java API, and does not include division. Not very mysterious. -- Orthotope , 8 November (UTC)

Determining Factors?[edit]

Is there any way to see how Seeds work? For example, what each individual number does to affect the world generation? I like to think that that certain biomes and structures are assigned to a number, and the number determines where they spawn. Can anyone prove/disprove this?

Just taking a look at Java's Random class will disprove that. All the seed is is a number that's fed into an algorithm that spits out a seemingly random set of numbers. There is no correlation to specific values of the input and results of the output. Thedarkfreak , 31 January (UTC)

Identical seeds[edit]

As i read in the seed article, it says the seed is generated using the system time.

Knowing that, those that means that if 2 players, at the same time, create a world with a "random" seed, will the world be identical (with different spawnpoints)?

If there is someone there with 2 computers to test this, please try, i am not able to do this.

Thanks,

ijzm aka anonymous user –Preceding unsigned comment was added by (talk) , 17 December (UTC). Please sign your posts with ~~~~

Technically, yes; it would be like entering the same seed by hand. However, "at the same time" means within one millisecond, so it's almost impossible to actually do this. -- Orthotope^talk , 17 December (UTC)

Entropy of Minecraft seeds[edit]

Minecraft seeds generated on the server end randomly come from:

As documented in the Java documentation, there are only actually 2⁴⁸ possible outputs of this.

On the other hand, seeds generated for single-player worlds don't seem to follow the pattern of this. For example, is a SSP seed I just generated in , which is not a valid output of nextLong(). On the other hand, my local craftbukkit server has a seed of , which is valid. An older SSP world I have has the seed , which is also a valid output.

About the seed generation and integer reading[edit]

So when the player enters a number that encodes to longer than 64 bits, what does the game do? , 7 June (UTC)

If it can't be parsed as a valid long integer, it will be hashed as a text string. -- Orthotope^talk , 7 June (UTC)

Mechanics[edit]

As of yet, there are a few theorys as to how these things work. I am somewhat new to wikis, so I probably shouldnt have dumped a theory in the page. Shall we post them here? Lugnut1206 22:45, 22 February 2011 (UTC)

I have double checked that the same seed results in the same map. The spawn is different though, otherwise the seed is pretty much pointless.Lordhazzard 22:46, 22 February 2011 (UTC)

http://en.wikipedia.org/wiki/Random_seed

The seed number is used by the random number generator to make a sequence of "random" numbers to generate a "random" map. So using the same seed number should always generate the same map. I think the first random number generator took the middle four digits of a six-digit number and squared it to get the next number (or something like that).--PurpleKiwi 22:51, 22 February 2011 (UTC)

I've been testing out different seeds from the infamous 103, l33t, Notch, 4, 1. None of these produce the same results as what I was told I would receive. All very standard worlds with a few "landmarks" of sorts but nothing like I was told to expect. Try using a 19 digit seed and see if those produce similar results so there won't be any random digits added since you filled the field. MDR 22:55, 22 February 2011 (UTC)

I thought the same thing, but when i generate the map "1" a few times, i noticed the spawn moves and theres a sand + sign landmark thats a good marker. The map is the same in theory, but i think there are minor changes including trees, sand (if it moves?), mobs etc... Lordhazzard 22:57, 22 February 2011 (UTC)

Also i think to make things a lot easier, it would be good for players to goto x:0 and z:0 of the seed they generate and using that as the basis for the map design/layout/shape/biomes Lordhazzard 23:05, 22 February 2011 (UTC)

Some seeds provide everytime the same map with the same spawn location (like the seed "23"). It's said in the article that the spawn location is generated from the name of the world, but it doesn't work for the seed "23". In fact, if a seed provides a map with a spawn location of x=0.5 y=... z=0.5, then it will be always the same spawn location if you generate a new map with that seed (like "23" or "Glacier") whatever is the name of the map. But if the spawn is located on other coordinates, then a new generated map with the same seed will be exactly the same, except with another spawn location. That's what I experienced in the game. --Zeteube 14:40, 24 February 2011 (UTC)

Lock?[edit]

Can someone lock this for now? Most of this is total garbage. All the stuff on specific map features and placements isn't true; these seeds are only general map averages. --Fishrock123 02:10, 23 February 2011 (UTC)

Different spawn point every time?[edit]

I tested this with a friend- first using notable seeds, such as Glacier and Archimedes, then with random gibberish. Result was 100% exact spawn.

Can we get some clarification on how a alphabetic seed is converted to numeric?[edit]

Does anyone know how the String.hashCode() function actually works?
The article lists the Calculation as "97 * 31**2 + 98 * 31 + 99 = 96354" (for the seed 'abc')
The Java documentation lists the formula for calculating hash codes as:
s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]
(where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation)
I'm confused, these two examples seems to differ from each other. Help? Superbun 19:45, 12 April 2011 (UTC)

I see no contradiction. s = the string, s[i] equals the character in the string, n = the length of the string. The string position is zero-indexed, so the count starts at zero. Going by the example above:

s = "abc"

n = 3

s[0] = 'a'. ASCII code of 'a' = 97.

97 * (31 ^ (n - 1))

97 * (31 ^ (2))

97 * 961 = 93217

s[1] = 'b'. ASCII code of 'b' = 98.

98 * (31 ^ (n - 2))

98 * (31 ^ 1)

98 * 31 = 3038

s[2] = 'c'. ASCII code of 'c' = 99.

99 * (31 ^ (n - 3))

99 * (31 ^ 0)

99 * 1 = 99

93217 + 3038 + 99 = 96354. Thedarkfreak 03:02, 14 April 2011 (UTC)

Discussion[edit]

My Opinion is as follows: Why I understand that the selection of interesting Seeds is subjective, I’d recommend to include Screenshots of some. While this is subjective, too, we have example screenies everywhere, so nobody could be opposed to that solution.

Regarding Fansites; I think they have their place here. Don’t think so? Would you kindly click on the Arrow next to “Minecraft” in the main site bar on the left? Fansite links are even there. We are all a community, everyone who doesn’t agree is free to leave.

Conclusion: If nobody has good reasons against my suggestions, I will carry them out in a few days. Revertings of this edit without a good reason will be reported and the reverter will be punkished for vandalism. ‒Flying sheep 21:10, 12 April 2011 (UTC)

I don't agree with putting interesting seeds on the page itself. Links to fansites dedicated to seeds, absolutely, but I don't think individual seeds have their place here. Just my opinion. --Abcorn^talk 21:33, 12 April 2011 (UTC)

Okay, here's a couple more ideas:

• Put them back and put a comment like <!-- Don't remove these! -->, or
• Put them on a subpage like {{static link|Random seed/Fansites}} --Abcorn^talk 02:29, 13 April 2011 (UTC)

@Abcorn: Of course, a listing of individual seeds is too subjective. It would be educational, however, to post a screenshot of e.g. 3666440496532277820, which proves that you can spawn inside a dungeon, … As previously said; screenshots are there to illustrate a topic and are subjective per definitionem. So we could use them for 1-2 interesting seeds.

I think we should keep the links like this (or similar)

I have no problem with you providing a link under External links. It appears what you are offering is different than what is there. However, remember that this is not an advertising service.

Understood. If someone objects to the addition, I'll remove it. I had a link to this up before, but it was removed during the fansite update war. The reason given was that the original link I provided was a direct link to the JAR file(I didn't have the program on GitHub then). I thought that was a reasonable explanation, as having the direct link on this page would cause a person's browser to ask to download something without knowing much of what it is. With this new link, they get linked to a page with a better description of the program before downloading it. Thedarkfreak 00:36, 15 April 2011 (UTC)

"no random seed that will give you (...) entirely desert world."[edit]

Uhm, is it actually correct that it's impossible to obtain a entirely desert world? I mean, unless there is some criteria which somehow prevents such worlds being generated, or biomes exceeding certain size, wouldn't it theoretically be possible, although extremely unlikely to get a world in which only desert biome is generated? –Preceding unsigned comment was added by Mastadi^{(Talk|Contribs)} 01:49, 21 April 2011.

Worlds are infinite, there's no biome big enough to cover an infinite space. 80% sure they have size limits. –User:Ultradude25^{(User:Ultradude25/t|User:Ultradude25/c)} at 02:11, 21 April 2011 (UTC)

But wouldn't it be possible to have two (or in this case, infinite amount) biomes of the same kind next to each other, thus appearing like a single big biome? Mastadi 17:10, 21 April 2011 (UTC)

Well, given how the moisture scale works for biomes I think it's technically possible, but it would be a freak occurrence that such a seed fits inside the seed generation box. I think the comment on the page, while potentially misleading, is accurate enough to be a worthwhile piece of information to someone who doesn't know much about random seeds. --Theothersteve7 17:37, 21 April 2011 (UTC)

I have a few questions. 1. There are some programs or mods to change the size of biomes, like desert=99 and tundra=0 means that the desert cover 99.5% or something of the map and the other biomes 0,5% of the world (excluding tundra), but does that change the map, for example, if you have plains=99 and the other are 0, does that means that the mountains are removed, or that just the grass, trees and sugercane locations have changed? 2. Also, is it possile to regenerate a floating dungeon (I made one with a zombiepigman spawner with MCedit to scare the pplz on my SMP server). 3. Also, talking about SMP, is it possible to create an seed with enfinite number/symbols/letters, cause I have tried this (685#5CDUpskirt&85gx93Yrs~? and it gives a very weird world, but is this bigger then the SSP seed lenght? timmytimmy 12:22, 6 July 2011 (UTC)

1. That depends entirely on the mod in question, not the MC level generator. If you want to know, you'll have to either download mods and try for yourself, or ask in the appropriate forum threads.
2. I don't think floating dungeons are ever generated by the level generator; I have yet to either hear anything about one, or to see one myself.
3. No.

Relevant info?[edit]

While working through some code for random seeds, I noticed something about the datatypes, that suggests that if you're using strings or phrases for the seeds in worlds, then you'll only be able to access a fraction of the available possibilities for seeds. The reason is, if a string is found in the World Seed entry field, then the Java hashCode() function is used on the string to obtain a unique hash from it. However, this function returns a 32-bit integer(datatype int). The Random number generator's seed is a 64-bit integer(datatype long), and is stored as such in the save file. The other 32 bits seem to get filled with 1s when the int is upscaled to long. Those bits don't change depending on what string is entered.

However, if a numeric seed is entered, or Minecraft is allowed to generate a seed on its own, all 64 bits can be filled with information. Jeb's blog post on the seed generator says that Minecraft uses the current system time to generate a random seed. The most likely function used is System.currentTimeMillis(), which returns a long value, the current system time in milliseconds. This also uses all 64 bits, instead of being restricted to 32.

Using pure numbers, or Minecraft's generation, allows for exponentially more possible worlds. Using a string, you're restricted to 2^32, or about 4 billion possible worlds(4,294,967,296 possibilities, to be exact). Now square that number, and that's how many possible worlds that the full 64 bits allows for. (2^64 possibilities, or about 18 quintillion possible worlds(18,446,744,073,709,551,616 possibilities, to be exact))

So, I was wondering if information considering this should be added to the article, stating that you won't be able to access as many potential worlds using seeds as you would otherwise. Sorry for the infodump :P -- Thedarkfreak 05:16, 26 April 2011 (UTC)

Sounds relevant enough to me. Feel free to add it, and in the future remember that it's alright to add this kind of thing right away after you've explained it(if it needs explaining). If it turns out to be unneeded it can always be reverted. -Alphap^{User talk:Alphap~Special:Contributions/Alphap} 05:38, 26 April 2011 (UTC)

Just a quick note on the above: although the Java data type used allows 2^64 possible values, Java's Class Random only uses 48 bits from the seed, so in fact there are only 2^48 possible worlds, not 2^64 as stated above. That's 281,474,976,710,656 if anyone's really interested.--Euryleia 08:27, 25 May 2011 (UTC)

Ah, I didn't know that. Thanks! -- Thedarkfreak 05:00, 28 May 2011 (UTC)

Experimenting with Seed logic[edit]

I did a few experiments with worldseeds, writing a java program to try to find the worldseed match based on known outcomes from using it. Example: Slimes only spawn in 10% of all chunks. So, if you know enough chunks that spawn slimes, the theory is that you could can possibly narrow down the seed. Here's what I found out, using a world with 17 known slime chunks.

- It was pretty easy to find my string seeded world, because there are "only" 4.3 billion or so positive and the same amount of negative numbers. It didn't take long to write the program in Java or to run it against the array of chunks. String.Hashcode() = successful.

- I tried another world creation, noting the system time, and looked to see if it could find my worldseed. While running Random() against long integers to represent the range given by System.currentTimeMillis(), I gave it a range of 10m each way, and let it run. It couldn't find it. That's because it does not use System.currentTimeMillis(), as previously believed. I found that Java's Random() is using nanotime (and some additional uniqueness added to it). What that means is, instead of searching inside a 20 minute range of 1000 random possibilities for each second, it's actually needing to be searching 1 billion randoms for each second. (Obviously, I didn't find the seed! I'd have to run the program for days, I think)

- To confirm, I looked at the world generation code using MCP, and confirmed that it used hashCode() for manually entered seeds, and Random() for blank seeds. The slime spawning algorithm was used to match the seeds with the array.

End result: It's quite possible to solve what seed a world is using, if you have enough data to feed it that is dependent on that seed, AND if the world was created with a string as the seed. If it was auto-generated, or numeric beyond a certain range worth searching in... not bloody likely! -Flenken–The preceding undated comment was added on 23:37, 2 July 2012.

Actually, this may be more feasible than you think. There are 284 trillion possible numeric seeds (2^48). If you had 15 known slime chunk coordinates, you would have enough to reliably determine a single seed (because 10^15 >> 2^48). I just wrote a heavily optimized algorithm in C to validate seeds against a hard-coded list of 15 chunks. Running on my 3.3 GHz i5 on a single core, it can check 1 billion seeds in 3 seconds. If this was run on all 4 cores simultaneously, it could check the entire seed space in approximately 2.5 days. If I wrote the code in assembly instead, or found a way to run it in GPU computing, it might be possible to reduce this time even further by another 2 or 3 orders of magnitude 65.172.18.11 14:05, 9 November 2012 (UTC)

Random seeds are 64-bit longs, not 48 bits, so the seed space is about 4 orders of magnitude larger than that. Checking everything on your computer would take around 70 years (actually even more, since you'd need 20 slime chunks instead of 15). Even with more optimization, that will take years of CPU time. Feasible if you have access to a server farm, perhaps, but not practical. -- Orthotope 22:48, 9 November 2012 (UTC)

The seeds are 64-bits long, but as stated above, Java's Random Class, which is what is used, only uses 48 bits of the seed for the generator. Thedarkfreak 04:25, 31 January 2013 (UTC)

swoop[edit]

Using the seed -1293644106920865080 which should spawn you in/above a dungeon, me and a few friends worked out that the chests will always contain: 3 gunpowder, 1 cocoa beans, 14 string, 2 bread, 2 saddles, 6 iron, and the spawner will be a skeleton spawner, so the contents of spawners and chests are set by the seed. Should it be included in the page or the chest and spawner pages? -19pxUser:OneshotUser talk:Oneshot1:01, 1 May 2011.

Why was the "Sites dedicated to Minecraft seeds" section removed?[edit]

I re-added it with my last update, because that's the format we agreed on here. Why was it removed, does anyone know?

If anyone has any objections to it, they should bring it up on this page, where we agreed on the format. ---Thedarkfreak 16:59, 2 May 2011 (UTC)

duplicate worlds[edit]

I decided to make a new world, so i deleted my old one and immediately created a new one. They were both random seeds. After exploring a bit, I found the house I had in my old world. Everything about the two duplicate worlds was the exact same, except the spawn point was different and all planted saplings were gone. Has this happened to anyone else? --Joejr50 01:45, 24 May 2011 (UTC)

That is very odd. It sounds like the game messed up loading something, and loaded the old world after never actually deleting it. Check your game files, see if the world is still there. If it is, delete it and try again. Check the seed generation page for how seed generation works, and somebody else could probably explain it in more technical terms. Deanm 01:50, 24 May 2011 (UTC)

There's a bug where the game sometimes fails to delete the files for an old world when it deletes the world. If you create another world with the same name, or a similar enough name that your OS's filesystem puts it in the same folder, you'll end up "resurrecting" the old world rather than creating a brand new one. If you used a different seed, when you start generating new chunks in your world, you'll get some very bizarre results. Worlds in collision... --Euryleia 08:40, 25 May 2011 (UTC)

It happened to me once! I was playing a creative mode game in a pine forest. I ran into a pack of wolves. I wanted to befreind them, but it seemed pointless and no fun. I deleted that game and made a new one, but in survival mode. I killed some skeletons at night and went to find some wolves. I couldn't find any, but when i was just about to get home, a tamed wolf came running up to me. It drowned when i was building a bridge, because it went under it and i didn't know. I wander why that happened. –Preceding unsigned comment was added by Sillybell^{(Talk|Contribs)} 01:27, 24 November 2011. Please sign your posts with ~~~~

Why was this moved to "Seed (Single player)"?[edit]

All of the info here also applies to SMP. SMP servers can set a seed in the server.properties file, and it behaves the same way single-player seeds do. –Preceding unsigned comment was added by Thedarkfreak^{(Talk|Contribs)} 05:03, 28 May 2011. Please sign your posts with ~~~~

I also have no idea what the logic was. We don't have {{static link|Seed (Multiplayer)}}, presumably because it's the same exact thing. I nearly moved it back, but the move tool nakked at me that it was an invalid move because the page already existed.--Billybobfred 19:07, 3 June 2011 (UTC)

How do I find a worlds seed if most of the world has been changed?[edit]

Well, it's just that my current favoured world is old and therefore doesnt have dungeons, tall grass, etc. that modern worlds have. And I would want to experience these new Minecraft world changes with this same world without using third party software.

No, you need to write 4 tildes (~). You will need to use a mod to get the world's seed, even if you haven't modified your world at all. Calinou - talk×contribs» 07:12, 29 May 2011 (UTC)

The two links under 'seed extraction' on the main page will help you get the seed. Either upload your level.dat file to the seed reader service at the first link, or download and run the Java tool in the second link, and select your world's name to get the seed. -- Thedarkfreak 05:11, 1 June 2011 (UTC)

Just wanted to add, depending on how old the world is, the world you regenerate may not look very similar. In particular, if the world is from before the Halloween update(which added Biomes, and drastically changed world generation), then any chunks generated before Biomes will not look anything alike. Minor updates don't change the generation code as much, and will usually result in similar terrain. -- Thedarkfreak 05:14, 1 June 2011 (UTC)

Seed shorter OR converter[edit]

There is a program that transforms a seed into a word, to make it shorter? --Gil2455526 22:11, 7 January 2012 (UTC)

There are far more number seeds than those that can be made using hashcode(), that is, letters/anything not a number, meaning you would get misinformantion if you tried to return the numbers to the strings that originally went through hashcode(). Also, very few of the strings would be shorter, even if you could get back to them. NighttimeDriver50000 21:29, 21 January 2012 (UTC)

Minecraft version Seed Compatability[edit]

We need a way to track when the minecraft version changes the world generation in a way that will cause a world to be generated differently.

For instance, a 1.0 minecraft will generate a different world than beta 1.6 even with the same seed.

The problem is if you update your minecraft server/client and try to reuse a map, you will get biome conflicts as the world generates new biomes that don't blend or match the other previously generated biomes. –Preceding unsigned comment was added by Flandar^{(Talk|Contribs)} 23:50, 9 January 2012. Please sign your posts with ~~~~

All you have to do is look at the changelist from the old version to the new version: if at any point you see anything about map generation (biomes are generated differently, or caves have been tweaked, or new generated features have been added, etc.), it's safe to assume that the change breaks seed compatibility. 「ディノ奴千？！」^{? · ☎ Dinoguy1000} 03:38, 10 January 2012 (UTC)

Strange spawn![edit]

For MC 1.2, the seed "Rebecca" (without the quotes) spawns the user in this tiny cave underground. There's no exit, and they're gravel in the ceiling that falls all the time, and its pitch black with a water covered floor. How could it spawn me in a cave? Puzzled, Jesse V 23:55, 4 March 2012 (UTC)

Seed from the old biome code?[edit]

The seed '2416767310099458792' appears to me to be from the old biome code. There is a taiga, as well as a desert, and a long, long stretch of the old-fashioned kind of sloping mountain land.

If it generates under the current version of Minecraft, it's not from "old biome code". It's just a happy coincidence. Thedarkfreak 04:32, 31 January 2013 (UTC)

Seeds affecting mob spawns[edit]

Does the seed of the world affect its animal and monster spawning patterns? Like I've heard people say that a particular seed would spawn them nearby a bunch of pigs or cows or something. However, I thought that the spawning of creatures was random, and unrelated to the seed. Jedibob5 19:53, 19 May 2012 (UTC)

The mobs spawned when a chunk is first generated are determined by the world seed. After that, it is random. -- Orthotope 21:38, 19 May 2012 (UTC)

There are lots of slimers. Which become a problem If you let them.

I ran towards the sunset and came across one village with churchs and lots of praying people.

Run to sunrise and you get a different village.

Animals but NO trees. You need to gut some of the houses just to get by (logs for charcoal...crops for bread)

Multiple Endermen at night.

I'll buy you a beer if you survive the week......I did by building a garden on the church tower..

SP and SMP Seed differ?[edit]

I found a great Seed on Singleplayer that I gave to my Fiance so we could use that perfect location I found together. When he enters the Seed on SP then he gets the exact same map but when he enters it in Multiplayer then EVERY TIME it's a DIFFERENT world. We do go to the exact same coordinates every time but it's nowhere near similar. It was a worded Seed so I used the /seed command on SP which gave me a few digits. He then tried this but it again wasn't the same Map. Why is that? Is there something we have to add? Are SP seeds not "compatible" with Multiplayer seeds?

The multiplayer seed has to be set in the server.properties file, and then the world needs to be regenerated. Thedarkfreak 04:30, 31 January 2013 (UTC)

0 in level generation[edit]

i have two questions about seed. 1: what happens if you use the seed 0, or a seed consisting of just zeroes to generate a world? would it be just a blank world? 2: does the algorithm include division? if so, what happens if the level generator is forced to divide by 0? if nobody can find answers to these questions, then it just goes to show how mysterious 0 is. please look into this for me. –Preceding unsigned comment was added by 184.38.41.87^(Talk) 21:23, 7 November 2012‎ (UTC). Please sign your posts with ~~~~

If the seed entered is mathematically equal to zero ("0", "00000", etc.), a random seed is used, as if you had left the seed field empty. The algorithm for turning non-numeric seeds into numbers is documented in the Java API, and does not include division. Not very mysterious. -- Orthotope 04:28, 8 November 2012 (UTC)

Determining Factors?[edit]

Is there any way to see how Seeds work? For example, what each individual number does to affect the world generation? I like to think that that certain biomes and structures are assigned to a number, and the number determines where they spawn. Can anyone prove/disprove this?

Just taking a look at Java's Random class will disprove that. All the seed is is a number that's fed into an algorithm that spits out a seemingly random set of numbers. There is no correlation to specific values of the input and results of the output. Thedarkfreak 04:29, 31 January 2013 (UTC)

Identical seeds[edit]

As i read in the seed article, it says the seed is generated using the system time.

Knowing that, those that means that if 2 players, at the same time, create a world with a "random" seed, will the world be identical (with different spawnpoints)?

If there is someone there with 2 computers to test this, please try, i am not able to do this.

Technically, yes; it would be like entering the same seed by hand. However, "at the same time" means within one millisecond, so it's almost impossible to actually do this. -- Orthotope^talk 19:24, 17 December 2013 (UTC)

Entropy of Minecraft seeds[edit]

Minecraft seeds generated on the server end randomly come from:

As documented in the Java documentation, there are only actually 2⁴⁸ possible outputs of this.

On the other hand, seeds generated for single-player worlds don't seem to follow the pattern of this. For example, -85074856741739097 is a SSP seed I just generated in 1.7.2, which is not a valid output of nextLong(). On the other hand, my local craftbukkit server has a seed of -2661703906412251709, which is valid. An older SSP world I have has the seed 6330060829006520259, which is also a valid output.

About the seed generation and integer reading[edit]
