Moving an object along a curve with AS

hello guys, ā€¦ iā€™m stuck and i need your help :angel:

i want to create a menu similar to The Infinite Menu (Link here), but with the difference that the menu will not run along a straight line, but along a curve (elipse).

I allready created a tween along a path, but it looks ugly when movement is slow, cuz of the limited frames :a:

any you guys have any ideas how to make this?

tnx, Shulchi
