Bad practice to use tween function in loop event?

[ukla]

Is it bad to use a tweening function in a loop event?

 

I have never had an issue with doing it this way. Just curious to know if it is a bad practice.

 

addEventListener(Event.ENTER_FRAME, loop);
private function loop(e:Event):void
{
    var distx:Number = (mouseX - stage.stageWidth*0.5)/100;
    var disty:Number = (mouseY - stage.stageHeight*0.5)/100;

    TweenMax.to(_currentitem, 1, {rotationX:-disty,ease:Expo.easeOut });

    TweenMax.to(_container, 1, {shortRotation:{rotationY:_roty + distx},ease:Expo.easeOut });
    sortZ();
}

It's acceptable to do it. A bit processor-intensive, but doable. I've seen it done many times before.
