use this function

pawn Code:

stock VehicleOccupied(vehicleid)
{
    for(new i=0;i<MAX_PLAYERS;i++)
    {
        if(IsPlayerInVehicle(i,vehicleid)) return 1;
    }
    return 0;
}

then do something like this

pawn Code:

if(!VehicleOccupied(vehid))
{
//your code respawn here
}

you must define the vehid yourself
