This callback is called when a player starts to enter a vehicle, meaning the player is not in vehicle yet at the time this callback is called.
|playerid||ID of the player who attempts to enter a vehicle.|
|vehicleid||ID of the vehicle the player is attempting to enter.|
|ispassenger||0 if entering as driver. 1 if entering as passenger.|
It is always called first in filterscripts.
This callback is called when a player BEGINS to enter a vehicle, not when they HAVE entered it. See OnPlayerStateChange. This callback is still called if the player is denied entry to the vehicle (e.g. it is locked or full).
