Here's a completely different way:

at the start of your script, add this:

pawn Код:

new object;

and

pawn Код:

forward close();

now, under OnGameModeInit add this

pawn Код:

public OnGameModeInit()
{
           object = CreateObject(your gate informations);
           return 1;
}

Now, get the coordinates of the gate when it's opened, and now you need the command..

pawn Код:

if (strcmp("/openmygate", cmdtext, true, 10) == 0)
{
        MoveObject(object, and then type here the new coordinates when it's opened,and now the speed you want the gate to open);
        SetTimer("close", 7000, 0); // 7000 = 7seconds
        return 1;
}

and now, the coordinates of the gate when it closes:

pawn Код:

public close()
{
       MoveObject(object, new coordinates of the gate when it close, speed);
       return 1;
}

Hope I helped..
