[Tween a drag and drop]

I am trying to drag and drop a very large movie clip (1600 X 1000), and would like to use a tween to make the dragging and dropping smooth.

 

 

 

holder_mc.addEventListener(MouseEvent.MOUSE_DOWN, PickImage);
stage.addEventListener(MouseEvent.MOUSE_UP, DropImage);

function PickImage (e:MouseEvent):void {
	holder_mc.startDrag();
	TweenMax.to(holder_mc, .2, {x:mouseX, y:mouseY, ease:Sine.easeInOut});
}

function DropImage(e:MouseEvent):void {
holder_mc.stopDrag();
       TweenMax.to(holder_mc, 4, {x:mouseX, y:mouseY, ease:Sine.easeInOut});

}

 

My method is all wrong. The movie clip want to snap to its registration point rather than jus tpick up where it was clicked. Maybe it should follow the mouse after a click instead? And how would I tween it tom make it nice?

 

Im trying to achieve an effect similar to this -- http://journey-to-zero.com/#/RSW
