In shape tweening, you draw a vector shape at one specific frame in the timeline and change that shape or draw another shape at another specific frame.
Flash then interpolates the intermediate shapes for the frames in between, creating the animation of one shape morphing into another
To create a shape tween:
- Start Flash and open a new blank document (ActionScript 3.0). Frame 1 in Layer 1 already contains a blank keyframe.
- Begin by adding a shape to the Stage
- Using the Selection tool, select frame 10 .
- Select Insert > Timeline > Keyframe.The tween will last for 10 frames.
- Make sure frame 10 is still selected and make one or more of the changes to your shape, or delete that shape and draw another shape.
- Click anywhere inside the tween span on the timeline and select Insert > Shape Tween or Right Click, Choose Shape Tween from Context Menu.
- Green shading with an arrow between keyframes indicates a shape tween span .
- Select frame 1 on the timeline (on the current layer).
- In the Tweening section of the Properties panel, adjust one or more properties of the Shape tween Ease, Blend(Distributive or Angular).
- Select Control > Test Movie > In Flash Professional to test the movie.
