Constructor & Destructor Documentation

net.minecraft.world.chunk.Chunk.Chunk	(	World	par1World,
		int	par2,
		int	par3
	)

net.minecraft.world.chunk.Chunk.Chunk	(	World	par1World,
		byte[]	par2ArrayOfByte,
		int	par3,
		int	par4
	)

net.minecraft.world.chunk.Chunk.Chunk	(	World	world,
		byte[]	ids,
		byte[]	metadata,
		int	chunkX,
		int	chunkZ
	)

Metadata sensitive Chunk constructor for use in new ChunkProviders that use metadata sensitive blocks during generation.

Parameters

world	The world this chunk belongs to
ids	A ByteArray containing all the BlockID's to set this chunk to
metadata	A ByteArray containing all the metadata to set this chunk to
chunkX	The chunk's X position
chunkZ	The Chunk's Z position

net.minecraft.world.chunk.Chunk.Chunk	(	World	world,
		short[]	ids,
		byte[]	metadata,
		int	chunkX,
		int	chunkZ
	)

A Chunk Constructor which handles shorts to allow block ids > 256 (full 4096 range) Meta data sensitive NOTE: The x,y,z order of the array is different from the native Chunk constructor to allow for generation > y127 NOTE: This is possibly more efficient than the standard constructor due to less memory skipping

Parameters

world	The world this chunk belongs to
ids	A ShortArray containing all the BlockID's to set this chunk to (x is low order, z is mid, y is high)
metadata	A ByteArray containing all the metadata to set this chunk to
chunkX	The chunk's X position
chunkZ	The Chunk's Z position
