There is no reason for the light queue to even be an option. This enables the light queue for everyone. This also improves the "can we still tick" time logic to always check before running a light operation. previously, we always executed at least 10 on the first world (but not other worlds...), but we are seeing light take up some heavy time, so improving that for now. I've now also improved recheck gaps logic to happen at the end of all single block updates This also prevents multiple gap checks, as previously if a tick skipped the gaps check, the next tick would end up re-adding the entry again, resulting in multiple gap checks. This now just sets a marker "We need to recheck gaps" and will only occur once. This also should reduce chunk loads, as previously, we checked if the neighbor chunks were loaded for the gap check, however those neighbor chunks might of unloaded before the light queue operation actually ran. Now, the neighbor chunk is done when the gap check is being done, so it should avoid loading chunks. Fixes #1466 Fixes #1431

Subject: [PATCH] Optimize isValidLocation, getType and getBlockData for inling
|
|
|
|
Hot methods, so reduce # of instructions for the method.
|
|
|
|
Move is valid location test to the BlockPosition class so that it can access local variables.
|
|
|
|
Replace all calls to the new place to the unnecessary forward.
|
|
|
|
Optimize getType and getBlockData to manually inline and optimize the calls
