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.
