Working with motion tweens
Copying motion tween scripts in Flash
Flash Player 9 and later, Adobe AIR 1.0 and later, requires Flash CS3 or later
A tween generates intermediate frames that show a display object in different states in two different frames on a
timeline. It creates the appearance that the image in the first frame evolves smoothly into the image in the second. In
a motion tween, the change in appearance typically involves changing the position of the display object, thus creating
movement. In addition to repositioning the display object, a motion tween can also rotate, skew, resize, or apply filters
to it.
Create a motion tween in Flash by moving a display object between keyframes along the timeline. Flash automatically
generates the ActionScript code that describes the tween, which you can copy and save in a file. See the Motion Tweens
section in Using Flash Professional for information about creating a motion tween.
You can access the Copy Motion as ActionScript 3.0 command in Flash two ways. The first way is from a tween context
menu on the stage:
1 Select the motion tween on the stage.
2 Right-click (Windows) or Control-click (Macintosh).
3 Choose Copy Motion as ActionScript 3.0 . . .
The second way is to choose the command directly from the Flash Edit menu:
1 Select the motion tween on the stage.
