GenLayer

public GenLayer(long p_i2125_1_)

Method Detail

initializeAllBiomeGenerators

public static GenLayer[] initializeAllBiomeGenerators(long p_75901_0_,
                                                      WorldType p_75901_2_)

the first array item is a linked list of the bioms, the second is the zoom function, the third is the same as the first.

initWorldGenSeed

public void initWorldGenSeed(long p_75905_1_)

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_)

returns a LCG pseudo random number from [0, x). Args: int x

getInts

public abstract int[] getInts(int p_75904_1_,
                              int p_75904_2_,
                              int p_75904_3_,
                              int p_75904_4_)

Returns a list of integer values generated by this layer. These may be interpreted as temperatures, rainfall amounts, or biomeList[] indices based on the particular GenLayer subclass.

compareBiomesById

protected static boolean compareBiomesById(int p_151616_0_,
                                           int p_151616_1_)

returns true if the biomeIDs are equal, or returns the result of the comparison as per BiomeGenBase.isEqualTo

isBiomeOceanic

protected static boolean isBiomeOceanic(int p_151618_0_)

returns true if the biomeId is one of the various ocean biomes.

selects a random integer from a set of provided integers

selectModeOrRandom

protected int selectModeOrRandom(int p_151617_1_,
                                 int p_151617_2_,
                                 int p_151617_3_,
