Seeded worlds are special "codes" which tell the game's pseudo-random number generator (a sophisticated mathematical function which produces numbers that seem random) where to begin generating a world. Because the random number generator is actually just a mathematical function and thus always produces the same result when given a certain input, you can "seed" the generator to produce an entire series of random numbers on another computer that are exactly the same as they were originally produced on the first computer. | Seeded worlds are special "codes" which tell the game's pseudo-random number generator (a sophisticated mathematical function which produces numbers that seem random) where to begin generating a world.

− | + | To use a seeded world, select ''Create a New World'' during the main menu, then hit {{key|s}} to specify a seed. Type in the seed and hit {{key|Enter}}, then hit {{key|Enter}} one more time to begin generation. It will still take the normal amount of time to generate the world, and you will still have rejects before the world is produced. | |
− | + | The random seed used also determines the world's name if a random name is selected. This disrupts the sequence of psudeo-random numbers. As a consequence, a seed with a player-given name will result in a completely different world than the same seed with a random name. Seed publishers should specify whether a random or a given name was selected when generating the world. | |
Mineral content is determined at the time it is allocated, (essentially when you dig near it). Accordingly, the map seed determines the layers and therefore the probability of certain rocks/ores, but the ore veins themselves will vary. | Mineral content is determined at the time it is allocated, (essentially when you dig near it).
