Spigot still maintains some partial implementation of "tick skipping", a practice in which the MinecraftServer.currentTick field is updated not by an increment of one per actual tick, but instead set to System.currentTimeMillis() / 50. This behaviour means that the tracked tick may "skip" a tick value in case a previous tick took more than the expected 50ms. To compensate for this in important paths, spigot/craftbukkit implements "wall-time". Instead of incrementing/decrementing ticks on block entities/entities by one for each call to their tick() method, they instead increment/decrement important values, like an ItemEntity's age or pickupDelay, by the difference of `currentTick - lastTick`, where `lastTick` is the value of `currentTick` during the last tick() call. These "fixes" however do not play nicely with minecraft's simulation distance as entities/block entities implementing the above behaviour would "catch up" their values when moving from a non-ticking chunk to a ticking one as their `lastTick` value remains stuck on the last tick in a ticking chunk and hence lead to a large "catch up" once ticked again. Paper completely removes the "tick skipping" behaviour (See patch "Further-improve-server-tick-loop"), making the above precautions completely unnecessary, which also rids paper of the previous described incompatibility with non-ticking chunks.

Subject: [PATCH] Don't fire sync events during worldgen
|
|
|
|
Fixes EntityPotionEffectEvent
|
|
Fixes EntityPoseChangeEvent
|
|
|
|
Asynchronous chunk generation provides an opportunity for things
|
|
to happen async that previously fired synchronous-only events. This
|
|
patch is for mitigating those issues by various methods.
|
|
|
|
Also fixes correctly marking/clearing the entity generation flag.
|
|
This patch sets the generation flag anytime an entity is created
|
|
via StructureTemplate before loading from NBT to catch uses of
|
|
the flag during the loading logic. This patch clears the generation
|
|
flag from an entity when added to a ServerLevel for the situation
|
|
where generation happened directly to a ServerLevel and the
|
|
entity still has the flag set.
