Yeah you don't need commands for this.
For a faction to open the gate to this:

pawn Код:

public CheckGate()
{
    new mygate_status;
    for(new i;i<MAX_PLAYERS;i++)
    {
        if(!IsPlayerConnected(i)) continue;
        if(IsPlayerInRangeOfPoint(i,10.0,closed_X,closed_Y,closed_Z))mygate_status=1;
    }
    if (GetPlayerTeam(playerid) == /*Your faction here*/
    {
        if(mygate_status)MoveObject(mygate, open_X, open_Y, open_Z,Moving Speed);
        else MoveObject(mygate, closed_X, closed_Y, closed_Z, Moving Speed);
    }
    else
    {
        return 1;
    }
}
