Thanks - the buttons are rectangular - any tips on how to calculate the corner positions if the displacement map is a gradient distorting on both x and y?

A possible workaround would be to calculate the new distorted hit area and manually build a button with those dimensions, using MovieClip.beginFill, MovieClip.lineTo, and so forth. Then set its alpha to zero and place it where it'll intercept clicks meant for the visually-distorted button (which you should just disable). Assuming the button is originally a rectangle, and you're applying a static hand-made displacement map, you should be able to calculate or estimate the transformed corner points of the button. Now, if your displacement map is dynamic, you have a much sticker situation... _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
