Question

I have the following function and interval, it is called once but then never again. Can anyone see why?

    function tweenArrow() {
        trace("called");
        var TweenAX:Tween = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
        var TweenAY:Tween = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);
    }
    setInterval(tweenArrow(),2000);

Answer 1

You are calling your function instead of giving a reference to setInterval. Try

setInterval(tweenArrow,2000);
