There are more issues.

- 3 specifiers and 2 arguments in sscanf.
- comparing "params" to a single number. "params" will hold two parameters so the check will fail. Compare integers instead with "doorid".

A better way is to store the states of the doors and apply only to the specified. If it is closed, it will open and vice versa.

PHP код:

CMD:vdoor(playerid, params[]) 
{ 
    new vehicleid, door; 
    if (sscanf(params, "ii", vehicleid, door)) 
    { 
        SendClientMessage(playerid, -1, "Usage: /vdoor <vehicleid> <door>"); 
        SendClientMessage(playerid, -1, "Doors: 0 - driver | 1 - passenger | 2 - back left | 3 - back right"); 
        return 1; 
    } 
    if (!GetVehicleModel(vehicleid)) return SendClientMessage(playerid, -1, "This vehicle does not exist."); 
    if (!(0 <= door <= 3)) return SendClientMessage(playerid, -1, "The value of 'door' parameter should be between 0 and 3"); 

    new driver, passenger, backleft, backright; 
    GetVehicleParamsCarDoors(vehicleid, driver, passenger, backleft, backright); 

    switch (door) 
    { 
        case 0: SetVehicleParamsCarDoors(vehicleid, !driver, passenger, backleft, backright); 
        case 1: SetVehicleParamsCarDoors(vehicleid, driver, !passenger, backleft, backright); 
        case 2: SetVehicleParamsCarDoors(vehicleid, driver, passenger, !backleft, backright); 
        case 3: SetVehicleParamsCarDoors(vehicleid, driver, passenger, backleft, !backright); 
    } 
    return 1; 
}
