pawn Код:

COMMAND:tune(playerid, params[])
{
    if(!IsPlayerInAnyVehicle(playerid)) return SedClientMessage(playerid, 0xFFFFFFAA, "You must be in a vehicle to use this command");
    {
        if(GetPlayerVehicleModel(playerid) !411)) return SedClientMessage(playerid, 0xFFFFFFAA, "You must have a elegy to use this command");
        {
            new vehicleid = GetPlayerVehicleID(playerid);
    
            AddVehicleComponent(vehicleid, 1034); //Alien Exhaust
            AddVehicleComponent(vehicleid, 1035); //X-Flow Roof Vent
            return 1;
        }
    }
    return 1;
}
