Animation where the moving, growing or shrinking disk has a little
more personality and rotates its "face" too.
Buttons have UP, OVER, DOWN and HIT states. Any of these can have its
own separate KeyFrame. Buttons are Symbols from the Library
What is the UP state for each button?
Contrast the UP state to the OVER state by moving your MOUSE on and
off the respective buttons.
Press your mouse button down to see the DOWN state.
What happens? Press and hold your mouse button down for a second
or so before you let it up. What happens?
We will see the importance of the HIT state later on. The HIT state
does NOT necessarily need to have a KeyFrame. You will see later why it
might
be funny if it did NOT have one for these buttons.
