Subject: [PATCH] Optimize NavigationListener
|
||
|
|
|
||
|
|
I believe Mojang intended to call the NavigationListener Block Update
|
||
|
|
method anytime a block is changed, but accidently added it for every
|
||
|
|
block physics event instead.
|
||
|
|
|
||
|
|
This code is massively ineffecient, and physics is so super hot, it
|
||
|
|
destroys server performance.
|
||
|
|
|
||
|
|
This patch moves the block update call to setTypeAndData instead of
|
||
|
|
on Physics.
