This callback was added in SA-MP 0.3z R4 and will not work in earlier versions!
This callback is called when a player sent a trailer update.
|playerid||The ID of the player who sent a trailer update|
|vehicleid||The Trailer being updated|
0 - Cancels any trailer updates from being sent to other players. Update is still sent to the updating player.
1 - Processes the trailer update as normal and synchronizes it between all players.
It is always called first in filterscripts.
This callback is called very frequently per second per trailer. You should refrain from implementing intensive calculations or intensive file writing/reading operations in this callback.
