Method Detail

getExtBlockID

public int getExtBlockID(int par1,
                         int par2,
                         int par3)

Returns the extended block ID for a location in a chunk, merged from a byte array and a NibbleArray to form a full 12-bit block ID.

setExtBlockID

public void setExtBlockID(int par1,
                          int par2,

                          int par4)

Sets the extended block ID for a location in a chunk, splitting bits 11..8 into a NibbleArray and bits 7..0 into a byte array. Also performs reference counting to determine whether or not to broadly cull this Chunk from the random-update tick list.

getExtBlockMetadata

public int getExtBlockMetadata(int par1,
                               int par2,

                                int par4)

Sets the metadata of the Block at the given coordinates in this ExtendedBlockStorage to the given metadata.

isEmpty

public boolean isEmpty()
