This enables us a fast reference to the entities current chunk instead of having to look it up by hashmap lookups. We also store counts by type to further enable other performance optimizations in later patches.

Subject: [PATCH] Handle bad chunks more gracefully
|
|
|
|
Prior to this change the server would crash when attempting to load a
|
|
chunk from a region with bad data.
|
|
|
|
After this change the server will defer back to vanilla behavior. At
|
|
this time, that means attempting to generate a chunk in its place
|
|
(and occasionally just not generating anything and leaving small
|
|
holes in the world).
|
|
|
|
Should Mojang choose to alter this behavior in the future, this change
|
|
will simply defer to whatever that new behavior is.
