If this is true recordBlock is called on chunk updates and on single block updates. This might be inefficient for some modules, so they can choose to not call that method on chunk updates.

Functions

allPositions

abstract fun allPositions(): Sequence<BlockPos>

Returns a Sequence providing all tracked BlockPos.

chunkUpdate

override fun chunkUpdate(chunk: LevelChunk)

Is called when a chunk is initially loaded or entirely updated.

clearAllChunks

abstract fun clearAllChunks()

clearChunk

abstract fun clearChunk(pos: ChunkPos)

getStateFor

abstract fun getStateFor(pos: BlockPos, state: BlockState): T?

Gets the state of specified BlockPos and its BlockState.

isEmpty

abstract fun isEmpty(): Boolean

Returns if there iss nothing tracked.

iterate

abstract fun iterate(): Sequence<Map.Entry<BlockPos, T>>

Returns a Sequence providing all tracked BlockPos and its state T.

onUpdated

open fun onUpdated()

recordBlock

override fun recordBlock(pos: BlockPos, state: BlockState, cleared: Boolean)

Registers a block update and asks the subscriber to make a decision about what should be done. This method must be thread-safe.

track

abstract fun track(pos: BlockPos, state: T)

Tracks a BlockPos with state.

untrack

abstract fun untrack(pos: BlockPos): Boolean

Untracks a BlockPos.
