HitTestPoint trouble when moving root

Content

Hi,

basically, I’m having trouble with the hitTestPoint method. As soon as I move the root of the swf, it no longer works as it should.

To see what I mean, run this code:

package todd.test
{
    import flash.display.MovieClip
    import flash.events.Event;
    import flash.display.Sprite;
    import flash.events.MouseEvent;
    import flash.geom.Point;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;
    
    import com.containers.ContentScroller;
    
    public class Main extends MovieClip
    {
        private var block:Sprite = new Sprite();
        private var dummyBlock:Sprite = new Sprite();
        
        public function Main():void
        {
            block.graphics.beginFill(0x00C000);
            block.graphics.drawRect(-50, -50, 100, 100);
            block.graphics.endFill();
            addChild(block);
            
            dummyBlock.graphics.beginFill(0x00C000, 0.2);
            dummyBlock.graphics.drawRect(-50, -50, 100, 100);
            dummyBlock.graphics.endFill();
            
            this.addEventListener(Event.ADDED_TO_STAGE, added);
        }
        
        private function added(e:Event):void
        {
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align  = StageAlign.TOP_LEFT;
            
            stage.addEventListener(MouseEvent.MOUSE_UP, stageMouseUp);
            stage.addEventListener(Event.RESIZE, resize);
            
            stage.addChild(dummyBlock);
        }
        
        private function resize(e:Event):void
        {
            this.x = stage.stageWidth* 0.5;
            this.y = stage.stageHeight * 0.5;
        }
        
        private function stageMouseUp(e:MouseEvent):void
        {
            var point:Point = new Point(stage.mouseX, stage.mouseY);
            trace("Stage Click", point, block.globalToLocal(point));
            trace("hit?", block.hitTestPoint(point.x, point.y));
        }

    }
}

Click the square, everything works as normal. Then resize the stage and try clicking it again, no such luck. But the “ghost” square works when clicked on.

I would just pass in the root as the coords (which seems to work every time), but at some points I don’t have a reference to the root.

Does the root always have to be at (0, 0) for this function to work? or is there anyway I can compensate for it?

Cheers!
