Hi,

hitTestPoint works fine in my application until the application is scaled. I’m hoping that someone can explain where I’ve gone wrong. In the following details the ‘source’ is a sprite being dragged over the ‘target’.

Display Hierarchy:  
stage  
frame [frame.swf]  
content [content.swf]  
source & target sprites

Hit Test Pseudo-code [content.swf]:  
var pt:Point = source.parent.localToGlobal( new Point( source.x, source.y ) );  
if( target.hitTestPoint( pt.x, pt.y, true ) )  
{ … }

Scaling Pseudo-code [frame.swf]:  
stage.scaleMode = StageScaleMode.NO\_SCALE;  
stage.align = StageAlign.TOP\_LEFT;  
…  
scaleX = \<computed scale\>;  
scaleY = \<computed scale\>;

Cheers!
