getAuxLightManager

public LevelChunkAuxiliaryLightManager getAuxLightManager(ChunkPos pos)

Description copied from interface: IBlockGetterExtension

Get the AuxiliaryLightManager of the chunk at the given ChunkPos.

The light manager must be used to hold light values controlled by dynamic data from BlockEntitys to ensure access to the light data is thread-safe and the data is available during chunk load from disk where BlockEntitys are not yet added to the chunk.

Specified by:

getAuxLightManager in interface IBlockGetterExtension

Parameters:

pos - The position of the chunk from which the light manager is requested

Returns:

the light manager or null if the chunk is not accessible (ChunkSource.getChunkForLighting(int, int) returned null) or the given implementation of BlockGetter does not implement this method

syncData

public final void syncData(AttachmentType<?> type)

Description copied from interface: IAttachmentHolder

Syncs a data attachment of the given type with all relevant clients.

If there is currently no attachment of the given type, the removal of the attachment is synced to the client.

Specified by:

syncData in interface IAttachmentHolder
