I'm learning loads in my first few days of using flex and
actionscript 3, however, I am stuck and need some help.
As of now I have a rotating disc that rotates on click of a
start button. What I need is a mask that shows the disc as a semi
circle at the bottom of the page but allows the circle, while
spinning, to have the top half of the disc visible.
I have looked into masking in flex but can't quite grasp how
they will be implemented into my example.
