Question

I need to develop my own drag function in AS3 (instead of using startDrag) because I’m resizing a MovieClip.

I’m doing this:

public class resizeBR extends MovieClip {

        var initialScaleX, initialScaleY;

        public function resizeBR() {            
            this.addEventListener(MouseEvent.MOUSE_DOWN, initResize);
            this.addEventListener(MouseEvent.MOUSE_UP, stopResize);
        }

        public function initResize(e:MouseEvent):void
        {
            initialScaleX = e.target.scaleX;
            initialScaleY = e.target.scaleY;
            e.target.addEventListener(MouseEvent.MOUSE_MOVE, startResize);
        }

        public function startResize(e:MouseEvent):void
        {
            e.target.x +=  e.localX;
            e.target.y +=  e.localY;
            e.target.parent.parent.width +=  mouseX;
            e.target.parent.parent.height +=  mouseY;
            // Keep its own scale
            e.target.scaleX = initialScaleX;
            e.target.scaleY = initialScaleY;

        }

        public function stopResize(e:MouseEvent):void
        {
            e.target.removeEventListener(MouseEvent.MOUSE_MOVE, startResize);
        }
    }

But the drag feature is not working fluently. I mean, when I drag a MovieClip from class resizeBR I need to move slowly my mouse cursor or it’s not going to work propertly.

resizeBR is a MovieClip as a child of another MovieClip; the second one is which I have to resize.

What am I doing wrong?

Thanks!
