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] Add PlayerShieldDisableEvent
|
|
|
|
Called whenever a players shield is disabled. This is mainly caused by
|
|
attacking players or monsters that carry axes.
|
|
|
|
The event, while similar to the PlayerItemCooldownEvent, offers other
|
|
behaviour and can hence not be implemented as a childtype of said event.
|
|
Specifically, cancelling the event prevents the game events from being
|
|
sent to the player.
|
|
|
|
Plugins listening to just the PlayerItemCooldownEvent may not want said
|
|
sideeffects, meaning the disable event cannot share a handlerlist with
|
|
the cooldown event
