Package net.minecraft.world.gen.chunk

Class ChunkGenerator

java.lang.Object
net.minecraft.world.gen.chunk.ChunkGenerator
All Implemented Interfaces:
BiomeAccess.Storage
Direct Known Subclasses:
DebugChunkGenerator, FlatChunkGenerator, NoiseChunkGenerator
public abstract class ChunkGenerator extends Object implements BiomeAccess.Storage
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.

    • locateStructure

      @Nullable public @Nullable BlockPos locateStructure(ServerWorld world, StructureFeature<?> structureFeature, BlockPos center, int radius, boolean skipExistingChunks)
      Tries to find the closest structure of a given type near a given block.

      New chunks will only be generated up to the ChunkStatus.STRUCTURE_STARTS phase by this method.

      The radius is ignored for strongholds.

      Parameters:
      radius - the search radius in chunks around the chunk the given block position is in; a radius of 0 will only search in the given chunk
      skipExistingChunks - whether only structures that are not referenced by generated chunks (chunks past the STRUCTURE_STARTS stage) are returned, excluding strongholds
      Returns:
      null if no structure could be found within the given search radius
