How to use hitTestPoint when a movie is scaled

Google says that:

displayObject.hitTest(stage.mouseX, stage.mouseY, true)

is the way to test for the mouse being over a DisplayObject开发者_运维问答. This works if my movie is displayed at 100% scale. But if maximise my browser window so the Flash movie changes scale, it all goes to pieces.

Does anyone have a way to fix this, please?

Many thanks.

I normally use:

 stage.addEventListener(MouseEvent.MOUSE_OVER, functionName);

But, if you have a specific reason for using the hitTest method, than you may want to look into converting your point from a global to a local MovieClip coordinate. Once you scale a MovieClip, it's x-y coordinates are no longer mapped 1-to-1 to the stage coordinates. BUT, you can make Flash figure out which coordinate you ARE talking about by using:

 yourMovieClip.globalToLocal( yourTestPoint )); // [x=-10, y=0]

Here is the related link with all the documentation...

You may also want to take a look at the "hitTestObject()" method which does the same thing as hitTestPoint, only using the entire object... no points!

hope this helps.
