Basics of Motion Tweens
Flash Player 9 and later, Adobe AIR 1.0 and
later, requires Flash CS3 or later
|
Motion tweens provide
an easy way to create animation.
A motion tween modifies display object properties, such as position
or rotation, on a frame-to-frame basis. A motion tween can also
change the appearance of a display object while it moves by applying
various filters and other properties. You create the motion tween
interactively with Flash Professional, which generates the ActionScript
for the motion tween. From within Flash, use the Copy Motion as
ActionScript 3.0 command to copy the ActionScript that created the
motion tween. Then you can reuse the ActionScript to create movement
in your own dynamic animation at runtime.
See the Motion Tweens section in
Using Flash Professional
for
information about creating a motion tween.
