Put this just under the #include

pawn Код:

#include <a_samp>

new admingate;

Now, put this in before return 1; in public OnGameModeInit, like so:

pawn Код:

public OnGameModeInit()
{
    SetGameModeText("Your Script");
    AddPlayerClass(0, 5.0, 5.0, 5.0, 269.1425, 0, 0, 0, 0, 0, 0);
    admingate = CreateObject(969, 0.0, 0.0, 3.0, 0.0, 0.0, 0.0);
    return 1;
}

Now, here comes the somewhat hard part. I'll use strcmp, the native PAWN command processor, forsake of experience of your scripting.

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/move", cmdtext, true, 10) == 0)
    {
        MoveObject(admingate, 0.0, 0.0, 10.0, 1.6);
        SendClientMessage(playerid, 0xFFFFFF, "The gate has magically moved!");
        return 1;
    }
    return 0;
}

To close, all you have to do is basically reverse it!

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/moveback", cmdtext, true, 10) == 0)
    {
        MoveObject(admingate, 0.0, 0.0, 3.0, 1.6);
        SendClientMessage(playerid, 0xFFFFFF, "The gate has magically moved back down!");
        return 1;
    }
    return 0;
}

And all you have to do is change the coordinates!

NOTE:THIS COMMAND IS FOR EVERYONE.
