A seed[1] is a code used in Minecraft's world generation process.[2] Each world has its own seed value which is used to keep generated terrain consistent, as generation is psuedo-random. Prior to Beta 1.3, seeds were automatically generated per-world. Since then, the player can input their own seed, which is not limited to numbers due to the use of the Java String.hashCode() function. For instance, a seed of "abc" is converted to the numeric value 97 * 31**2 + 98 * 31 + 99 = 96354.
Using the same seed to generate two separate worlds will generate the same terrain consistently, even on different systems. As such, seeds can be shared by players to generate the same world between them. However, the player's initial spawn point will be random; it is not tied to the seed value.[3]
Trivia
- If you leave the seed blank, the game will use the current computer clock to select a new seed. Thus the term "Random seed" is a misnomer, as it is never truly random.
