Subject: [PATCH] Avoid Chunk Lookups for Entity/TileEntity Current Chunk
|
|
|
|
SPECIAL 1.14.1 NOTE:
|
|
This patch caused a memory leak since the tile entity's chunk was set to null
|
|
before it was removed. Ensure this issue is resolved!
|
|
|
|
In many places where we simply want the current chunk the entity
|
|
is in, instead of doing a hashmap lookup for it, we now have access
|
|
to the object directly on the Entity/TileEntity object we can directly grab.
|
|
|
|
Use that local value instead to reduce lookups in many hot places.
