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:
-
Select the motion tween on the stage.
-
Right-click (Windows) or Control‑click (Macintosh).
-
Choose Copy Motion as ActionScript 3.0 . . .
The second way is to choose the command directly from the Flash
Edit menu:
-
Select the motion tween on the stage.
-
Select Edit > Timeline >Copy Motion
as ActionScript 3.0.
After copying the script, paste it into a file and save it.
After creating a motion tween and copying and saving the script,
you can reuse it as is or modify it in your own dynamic ActionScript-based
animation.
