pawn Код:

if (!strcmp (cmdtext,"/nos", true))
{
    if(IsPlayerInAnyVehicle(playerid))
    {
        new vehid, modid;
        vehid = GetPlayerVehicleID(playerid);
        modid = GetVehicleModel(vehid);

        if(modid != 581 && modid != 509 && modid != 481 && modid != 462 && modid != 521 && modid != 436 && modid != 510 && modid != 522 && modid != 461 && modid != 448 && modid != 471 && modid != 468 && modid != 586)
        {
            AddVehicleComponent(vehid,1010);
            return 1;
        }
        return SendClientMessage(playerid,0xFF0000FF,"Invalid vehicle!(probably a bike)");
    }
    return SendClientMessage(playerid,0xFF0000FF,"Enter a vehicle first!");
}
