Talk:Seed (level generation)

As of yet, there are a few theorys as to how these things work. I am somewhat new to wikis, so I probably shpuldnt 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)

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)

Rename
I suggest renaming this page to Seed (technical) (to avoid confusion with Seeds because the current title isn't useful. Is "technical" a good disambiguation for it though? --Gnu32 05:59, 23 February 2011 (UTC)
 * I'd have to say Seeds (technical) due to that's what it is. IKJames 15:36, 23 February 2011 (UTC)
