Class ChunkGenerator

java.lang.Object

net.minecraft.world.gen.chunk.ChunkGenerator

Direct Known Subclasses:

DebugChunkGenerator, FlatChunkGenerator, SurfaceChunkGenerator

public abstract class ChunkGenerator
extends Object

In charge of shaping, adding biome specific surface blocks, and carving chunks, as well as populating the generated chunks with features and entities. Biome placement starts here, however all vanilla and most modded chunk generators delegate this to a biome source.
