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] ExperienceOrb merging/stacking API and fixes
|
|
|
|
Adds an option for maximum exp value when merging orbs
|
|
|
|
Adds ExperienceOrbMergeEvent
|
|
Fired when the server is about to merge 2 experience orbs
|
|
as entities. Plugins can cancel it if they want to ensure experience orbs do not lose important
|
|
metadata such as spawn reason, or conditionally move data from source to target.
|
|
|
|
Fixes an issue where the stacked count was not taking into account
|
|
for mending repairs and when merging with spigot's merge-on-spawn
|
|
logic
|
|
|
|
== AT ==
|
|
public net.minecraft.world.entity.ExperienceOrb count
