ok. So, i found otu today that the reason words are used to generate a map is because of a mathmatical numeric system used in the game. I've went through a few map seeds trying to find one i might enjoy, and repeatable that could give better for others if they wished.

My question is, what do the numbers and names need to give the map it's unique structure, has anyone found out how the algorithm works to like, lets say, make sure the map spawns a mushroom biome, or always gets a giant desert, maybe ten villages and a mountain range. something. and if so, what number where can i get a big enough mushroom and a nether fortress with?

also, what makes a nether fortress worth going into the nether for? the amount of blaze spawns, the warts, what? besides brewing, what good is a nether fortress and what makes a nether fortress a good find and hat makes it not worth finding?

It's not a huge deal but I really lime the nether brick. You can turn it into nether stairs which also look cool imo.

nothing there

I don't think anyone has actually cracked the formula to figure out what sort of number strings result in this biome and that biome. You can, however, repeat a seed generation simply by typing in the same string in exactly the same way (punctuation and capitals count). That's why the seeds list (pinned thread) exists. People post a description of what they've found and the seed string they used so that other people can generate that seed if they think they might like a seed like it.

As for the nether in general being worth going into. Blazes and nether wart are essential to brewing potions. Ghast tears are also an ingredient in some potions. Glowstone has long been a popular block people use for light. Nether brick, nether brick stairs, and nether fence can currently only be found in the nether fortresses (that is, you cannot craft them). If you don't mind not having these items, you certainly don't have to go there. Once the End gets added to the game, using potions will become more of a necessity if you will want to take on the Ender Dragon.

That is a lot of seed to crack.... I think the squirrels in my yard would do better...

Seriously though like up said, I don't think any has actually cracked it. If someone did, it would probably be a mathematical formula that not all could understand completely.

As for anything that is entered that is not the preceding - or just all #s; Those characters and such always convert to a number, positive or negative. So in saying that, the seeds you would have to figure things out with would be just the numbers. That would be easier than thinking of what the others convert to, as it all has to be numbers to be stored as a seed #.

Even though people usually just do the words and such, which is sometimes easier to remember, it still has an actual #, that you find out after saving and exiting to the menu.

The nether, eh. Glowstone mainly, but now that there are pumpkins (farming) my hidden lighting (still obvious though) works a lot better assuming I find pumpkins right off the back or a mine shaft that has the seeds. I don't trust the fortress as not one of my maps I ever generate has an obvious one. I just would be nice if nether bricks were craftable, as the stairs and fences are. Beyond brewing there really is not much in the nether, unless you would rather take down ghasts for gunpowder instead of creepers. (I think they still drop that)

The formula could probably be figured out. Are you volunteering to go through 4 billion seeds for us?

All a "seed is" is an instruction set for a psuedorandom number generator. When are talking about "cracking the formula," what you are really talking about is determining how the RND function works within the code and what strings of random numbers would be produced. Then you would need to know how the code would interpret those sequences of numbers.

Think of it this way. Each seed tells the RND what sequence of numbers to produce. The code then interprets those numbers through the terrain generator.

I like having the nether and i want EVERYTHING on any map i play so the nether fortress is essential. As a side note I have explored a lot of maps both named and not putting anything in the seed generator. I have found that not putting anything in the seed generator line actually gives you a more balanced map overall.

I think it has to do something with the #'s 666 & 13.
