Need help with stopping a tween from looping after it is done playing

1

I’ve just started AS3 with no AS experience. I have an attack button to allow my character to run across the stage. The problem is it keeps looping after the tween finishes playing. I want to be able to stop and put my character back to frame 1 which is just a frame of the character standing there.

I’ve tried the following and still can’t get it to work…

Failed…
Trying to add a stop(); to various frames. It’ll just stop the entire mc.

Semi worked…
Tried a collision detection but the box just doesn’t make it look good.

Tried setting a timer, but don’t think that’s what I want.

Having a stop button works, but not what I want.

I’ve ran out of ideas. Any help is appreciated. Thanks. I uploaded the file since I’m over the limit here.

function onButtonAttackClick(event:MouseEvent):void
{
    if (playerTurn == true)
    {
        player.gotoAndStop("playerAttack2_mc");
        //playerAttack = false;
        //playerTurn = false;
        //trace("is now false");
    }
    
}
