A timer is un-necessary and I recommend using the following callback, which is called when an object finishes moving..

A similar callback is available for player objects and dynamic objects.

I assume you're using something like the following function to open/close it:

When using the move object function, I would set a variable belonging to the gate to indicate it is moving (not fully opened or closed). Then at the OnObjectMoved callback, set the variable to some number to indicate opened/closed position. For example, some psuedo code of how I might do it:

PHP код:

//Some Defines
#define GATE_POS_CLOSED 0
#define GATE_POS_OPENING 1
#define GATE_POS_OPEN 2
#define GATE_POS_CLOSING 3
//Some Variables
new myGate = CreateObject(...);
new myGatePos;
public OnObjectMoved(objectid)
{
    if (objectid == myGate)
    {
        //Check if object was opening..
        if (myGatePos == GATE_POS_OPENING)
        {
            myGatePos = GATE_POS_OPEN;    //Mark gate as now open
        }
        
        //Check if object was closing
        else if (myGatePos == GATE_POS_CLOSING)
        {
            myGatePos = GATE_POS_CLOSED;    //Mark gate as now closed
        }
    }    
    return 1;
}
SomeGateMovingFunction(...)
{    
    if (myGatePos == GATE_POS_OPEN)
    {
        MoveObject(myGate, ... to closed coordinates ...);    //Mov object toward closed pos
        myGatePos = GATE_POS_CLOSING;                //Mark object as closing
        
    }
    
    else if (myGatePos == GATE_POS_CLOSED)
    {
        MoveObject(myGate, ... to closed coordinates ...);    //Move gate toward open pos
        myGatePos = GATE_POS_OPENING;                //Mark object as opening
    }    
    return value;
        
} 


P.s. I have used a similar method in the past which worked successfully.
