Subject: [PATCH] Optimize BlockStateList/BlockData
|
|
|
|
Mojang included some sanity checks on arguments passed to the BlockData.
|
|
This code results in the Hash look up occuring twice per call, one to test if it exists
|
|
and another to retrieve the result.
|
|
|
|
This code should ideally never be hit, unless mojang released a bad build. We can discover bugs with this as furthur code that never expects a null
|
|
would then NPE, so it would not result in hidden issues.
|
|
|
|
This is super hot code, so removing those checks should give decent gains.
