hi,
got myself into a tough situation while trying to make something with text area.... it goes like this:

I have a background JPG, and on it a triangle with it's alpha set to 50% for instance. A part of this triangle is masked, and the background is seen through it...
I need to move the triangle and it's mask (the mask changes its place when different buttons are pressed {with easing} )
maybe the description sucks, but i dont have any better examples for now.
will be happy to hear some advise at least on the approach
thanks!
