Subject: [PATCH] Allow multiple callbacks to schedule for Callback Executor
|
|
|
|
ChunkMapDistance polls multiple entries for pendingChunkUpdates
|
|
|
|
Each of these have the potential to move a chunk in and out of
|
|
"Loaded" state, which will result in multiple callbacks being
|
|
needed within a single tick of ChunkMapDistance
|
|
|
|
Use an ArrayDeque to store this Queue
|
|
|
|
We make sure to also implement a pattern that is recursion safe too.
