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] Fire PlayerJoinEvent when Player is actually ready
|
|
|
|
For years, plugin developers have had to delay many things they do
|
|
inside of the PlayerJoinEvent by 1 tick to make it actually work.
|
|
|
|
This all boiled down to 1 reason why: The event fired before the
|
|
player was fully ready and joined to the world!
|
|
|
|
Additionally, if that player logged out on a vehicle, the event
|
|
fired before the vehicle was even loaded, so that plugins had no
|
|
access to the vehicle during this event either.
|
|
|
|
This change finally fixes this issue, fully preparing the player
|
|
into the world as a fully ready entity, vehicle included.
|
|
|
|
There should be no plugins that break because of this change, but might
|
|
improve consistency with other plugins instead.
|
|
|
|
For example, if 2 plugins listens to this event, and the first one
|
|
teleported the player in the event, then the 2nd plugin actually
|
|
would be getting a valid player!
|
|
|
|
This was very non deterministic. This change will ensure every plugin
|
|
receives a deterministic result, and should no longer require 1 tick
|
|
delays anymore.
