Continuous up and over button animation

In this tutorial you will learn how to make a button with a true reversed up and over animation. The trick here is not to put the animation inside the button itself but put the button inside the animated movie that you as whole would use as a button. The animation method of this tutorial is to create a one way animation that rolls out as you put the mouse on the button and rolls back once back starting from its current position once you move the mouse away from the button.
