it used public method instead of private, and moved to world config also improved the implementation to not use obfuscated stuff Also removed the Fix Double chest conversion patch since its fixed in other ways in vanilla

Subject: [PATCH] Optimize Light Recalculations
|
|
|
|
The server triggers light recalculations even if the new block
|
|
is the same as the old block. At this time, BlockData Properties
|
|
do not impact light calculations.
|
|
|
|
So the only way light should change, is if the block itself
|
|
changes from 1 block to another.
|
|
|
|
Also optimizes to not repeatedly look up the same chunk for
|
|
light lookups.
