Subject: [PATCH] API to get a BlockState without a snapshot
|
|
|
|
This allows you to get a BlockState without creating a snapshot, operating
|
|
on the real tile entity.
|
|
|
|
This is useful for where performance is needed
|
|
|
|
also Avoid NPE during CraftBlockEntityState load if could not get TE
|
|
|
|
If Tile Entity was null, correct Sign to return empty lines instead of null
|
