Create A Motion Tween With An Alpha Setting - MACROMEDIA FLASH 8-FLASH Tutorials Manual

174 Creating Graphics: Making Animations with Easing (Flash Professional only)
Create a motion tween with an alpha
setting
In this section, you will create a tween of the alpha value of the shadow
graphic that appears under the eight ball. Because the changes in the
shadow should match the speed and timing of the bouncing eight ball, you
will use the same easing curve you created in the previous section.
