Well I finally figured out why I shouldn't have skipped certain classes in school...
I have a circle with a point on it (marked with a red cross). The point is at x -60 and y 0 accodring to the circle's center. When I rotate the circle 90 degrees the x should be 0 and the y should be 90. But how can I calculate those values? I've been trying to work this out a bit but my math/algebra/triginomitry/whatever skills are non existend....
Can anyone look at my fla please and help me out on this subject?
