Method Detail

initializeAllBiomeGenerators

public static GenLayer[] initializeAllBiomeGenerators(long seed,
                                                      WorldType p_180781_2_,
                                                      ChunkProviderSettings p_180781_3_)

initWorldGenSeed

public void initWorldGenSeed(long seed)

Initialize layer's local worldGenSeed based on its own baseSeed and the world's global seed (passed in as an argument).

initChunkSeed

public void initChunkSeed(long p_75903_1_,
                          long p_75903_3_)

Initialize layer's current chunkSeed based on the local worldGenSeed and the (x,z) chunk coordinates.

nextInt

protected int nextInt(int p_75902_1_)

Generates a pseudo random number between 0 and another integer.

getInts

public abstract int[] getInts(int areaX,
                              int areaY,
