For some reason I just don't get Flash. I even bought the dummy book and took it out to my pool and read that thing and still don't get it. I can't even make a ball bounce. And I know if I could learn it I would do great with it.
Simple animation =
Draw a circle on your first keyframe.
Add new keyframe on say frame 20.
Drag circle to end point while frame 20 is still highlighted.
Right-click with your mouse in the timeline between frames 1 and 20.
Click 'create classic tween'.
Cntrl-Enter to test.
My syntax may be incorrect but that's basically how you do simple animations. You could add easing and tween the shape as well to create a more realistic animation, but that's how simple it is.
