this was degraded whenever it was I decided to make chunks always be allocated. This commit uses a fast path for light filling in subchunks which are completely clear of the heightmap, which returns the performance back to its old fast levels.
This commit fixes the 5+ years-old bug with the movement anti-cheat that everyone has complained about: sprinting on stairs causes rubberbanding.
This commit addresses this problem at long last, along with a handful of precursor commits that were necessary to fix this problem:
- dac76f0e0f
- 89fe8f7f10
- 2d77b1e364
Additionally, these changes now allow the anti-cheat to be accurate to at least 0.001 of a block, perhaps even better. I didn't commit a change to the threshold here, but it was instrumental to pinning down the exact nature of these bugs.
This closes#1475, at long last.
this fixes bugs where the entity would jump in the air when walking on blocks like carpet. It also fixes a lot of the issues with stepping in the anti-cheat, allowing to reduce the error tolerance on movement processing.
this was causing the movement anti-cheat to shit itself after the first movement because it used setPosition() on the player if the position wasn't exactly perfect (which obviously it never is perfect, because of fp rounding errors).
since the removal of EntityFactory::create() this isn't needed anymore, since these creation functions are only used for creating entities loaded from disk.
this bug became painfully obvious when testing bamboo. Detonating TNT near tall bamboo canes would result in bamboo canes not deleting themselves in some circumstances, because the non-destroyed parts of the cane would be updated before their supporting block was deleted, and subsequently would not be re-updated afterwards.
I think this bug should also reproduce with cacti, but I have not tested.
this version doesn't change any packets as far as I know, but it does change some packet content (most notably, some blockstates changed, which are troublesome when not in sync).
this allows generating a docblock / code for a registry without the class needing to exist or be populated yet, which makes code generation significantly less cumbersome.
