Talk:Seed (level generation)

Mechanics
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?
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)


 * 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 03:08, 23 February 2011 (UTC)


 * Pffft. People. Anyways, I think 0-9 and probably alter the terrain average, and mixing the numbers probably mixes and/or amplifies the terrain alterations. A-Z might aswell. --Fishrock123 03:55, 23 February 2011 (UTC)

Different spawn point every time?
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.

 * I tested this with a friend- first using notable seeds, such as Glacier and Archimedes, then with random gibberish. Result was 100% 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 capital.Mick666 05:03, 8 April 2011 (UTC)

Can we get some clarification on how a alphabetic seed is converted to numeric?
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)
 * 99 * 1 = 99

Discussion
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. --Abcorntalk 21:33, 12 April 2011 (UTC)


 * Whenever we allow fansites, we just have people revert warring over them. – ultradude25 ( T at 01:23, 13 April 2011 (UTC)


 * Just put the fansite links under "External Links", and ask people nicely to not revert.--Abcorntalk 01:36, 13 April 2011 (UTC)


 * That's exactly how it was before, but people still did it up until the point where they earned themselves a block. – ultradude25 ( T at 02:24, 13 April 2011 (UTC)


 * Okay, here's a couple more ideas:
 * Put them back and put a comment like, or
 * Put them on a subpage like Random seed/Fansites --Abcorntalk 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)



Link to my seed reader?
Just wondering if you guys think it'd be ok for me to add a link on this page to my seed reader: https://github.com/thedarkfreak/Minecraft-Save-Seed-Reader/wiki

The reason I suggest it is I find it much easier to use than the MC Seed Scope listed, as the user doesn't have to find and upload their level.dat file to get it. Thedarkfreak 03:02, 14 April 2011 (UTC)


 * 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. -- Wynthyst [[Image:User Wynthyst sig icon.png ]] talk  09:43, 14 April 2011 (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 00:36, 15 April 2011 (UTC)

"no random seed that will give you (...) entirely desert world."
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&#124;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. – ultradude25 ( T 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)


 * 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.
 * 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.
 * No.

Relevant info?
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 T ~ C 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
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.

duplicate worlds
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)

 * 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

 * 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
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&#124;Contribs) 23:50, 9 January 2012.

 * 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)

 * Try putting in 21071965


 * Its totally flat with 2 villages (that I could find)


 * There are lots of slimers. Which become a problem If you let them.
 * I nicknamed it "final days"
 * 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..
 * Its a long run and will need an emergency overnight bunker (dig down 2 and cover yourself in.
 * Good luck –Preceding unsigned comment was added by 94.5.16.138 (Talk) 22:38, 6 July 2012. Please sign your posts with

Minecraft 12w26a not showing seed
When I press F3 in Minecraft 12w26a Singleplayer, it doesn't even give me my seed anymore! Is there any way to find out my seed if I chose a random one now? 95.96.128.2 19:51, 30 June 2012 (UTC)


 * Right I got it, you have to type /seed in the chat screen, works with Cheats off. Putting it in Trivia. 95.96.128.2 19:57, 30 June 2012 (UTC)

SP and SMP Seed differ?
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?

0 in level generation
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).

 * 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)
