I have a image enlargement slider that the user can click on and drag up and down to enlarge an image next to the slider. The sticking point is that it has to slide in an arc. I created the slide bar attached to a large circle that should anchor the slide bar to a center point, but I can’t manage to constrain the dragging action to just rotation. I have tried to use a guide layer, but that doesn’t seem to work. So far, I just have code that allows the user to click on and drag the slide bar around, constrained in a small rectangle. Using code from the circular movement tutorial, I managed to anchor the centerpoint of the movie clip, but then the slide bar couldn’t move at all. How can I do this?
(Edit: I am currently checking out Afterburner’s post just below this one for clues…)
I can’t make sense of it… pretty advanced stuff. 
Edit2:
Senocular has some good stuff that may help me:
