CHAPTER 10
Creating Motion
Macromedia Flash Basic 8 and Flash Professional 8 offer several ways to include animation
and special effects in your document. Timeline effects, such as blur, expand, and explode,
make it easy to animate an object: you can simply select the object, then select an effect and
specify parameters. With Timeline effects, you can accomplish in a few easy steps a previously
time-consuming task that required more advanced knowledge of animation.
To create tweened animation, you create starting and ending frames and let Flash create the
animation for the frames in between. Flash varies the object’s size, rotation, color, or other
attributes between the starting and ending frames to create the appearance of movement. See
“About tweened animation” on page 248.
You can also create animation by changing the contents of successive frames in the Timeline.
You can make an object move across the Stage, increase or decrease its size, rotate, change
color, fade in or out, or change shape. Changes can occur independently of, or in concert
with, other changes. For example, you can make an object rotate and fade in as it moves across
the Stage. In frame-by-frame animation, you create the image in every frame. See “About
frame-by-frame animation” on page 249.
