How to Copy and Paste Motion in Adobe Flash CS6
A new addition to Adobe Flash CS6 is its capability to copy the behavior of a motion tween that you then paste into a completely different symbol instance. This technique is handy if you need to have multiple objects follow exactly the same animation behavior, such as birds of different colors and sizes all following the same flight pattern.
To copy and paste motion, you need an existing tween to copy from and then a symbol instance on a different layer to copy to. The following steps show you how to copy animation behavior from one tween that you can paste and apply to a different symbol afterward:
Select an existing tween span on the Timeline, right-click (Windows) or Control-click (Mac), and then choose Copy Motion from the contextual menu that appears.
On a new layer, place an instance of a symbol from your library.
It can be the same symbol you’ve already tweened or a completely different symbol.
Right-click (Windows) or Control-click (Mac) the first keyframe of the new layer and choose Paste Motion from the contextual menu that appears.
A new tween span is created.
Press Enter or Return to play your movie.
The new symbol instance animates in the same way as the original object from which its motion was copied.
You can work with two instances of the same symbol, but the beauty of this feature is that you can copy and paste animation between completely nonrelated symbol instances. You can also paste motion between symbol instances that have drastically different size, color, and rotation properties.
