Subject: [PATCH] Fix Longstanding Broken behavior of PlayerJoinEvent
|
|
|
|
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.
