PHP код:

CMD:mydoor(playerid, params[])
{
    if(PlayerInfo[playerid][pDoor1] == 1)
    {
       SetPlayerCheckpoint(playerd,DDinfo[PlayerInfo[playerid][pDoor1]][Ex],DDinfo[PlayerInfo[playerid][pDoor1]][Ey],DDinfo[PlayerInfo[playerid][pDoor1]][Ez], 3.0);
    }
    else
    {
        SendClientMessage(playerid, COLOR_WHITE, "You don't own a door.");
    }
    return 1;
}
