changed in frame 10 (for example, the widening applied in step 5). Right-click (Windows) or Control+click (Mac) anywhere in the span of frames between both keyframes, and select Create Shape Tween from the context menu (see Figure 7-3). Two things will happen: The span of frames will turn green, which indicates a shape tween. They will also gain an arrow pointing to the right, which tells you the tween was successful. The pepper will update to reflect a visual state between the artwork in either keyframe, depending on where the playhead is positioned.

If you applied the tween while in frame 1 a perfectly legal choice, by the way you wouldn t immediately see the pepper change. Why Because the tweening is applied between the two keyframes, and frame 1 still represents the artwork as it was before tweening changed it. Drag the playhead back and forth, and you ll see the tween.

9. Let s try another tween. Right-click (Windows) or Control+click (Mac) your frame span, and
choose Create Motion Tween. Motion tweening is not supported for shapes, and Flash gives you an unmistakable sign that you ve gone wrong. You ll see an alert box that offers to convert your shape into a symbol, as shown in Figure 7-5. Click OK, and you ll see most of your frame span turn blue, along with the appearance of a new movie clip in the Library.
Figure 7-5. Tweens other than the shape variety require symbols. It s nice that Flash does this for you, but generally speaking, you ll want to decide on your own what sort of symbol to create: movie clip, graphic, or button. Unfortunately, this automated process does the choosing for you. Motion tweens are part of the new After Effects like tweening model you ll learn about in 8. Motion tweens are nothing like shape tweens; they are an altogether different concept.
10. Select Edit Undo Create Motion Tween to step back. That sets the frames back and
automatically removes the Library s movie clip.
11. Time for another mistake. Right-click (Windows) or Control+click (Mac) your frame span, and
choose Create Classic Tween. Instead of green, the span of frames will become purple, and you ll see two new symbols in the Library (this time, graphic symbols) without even a warning! Purple frames indicate a classic tween, which you ll learn about later in this chapter. These, too, are nothing like shape tweens.
12. Perform an undo, and the frames will revert to a nontweened state. You ll need to delete the
graphic symbols by hand, though. Go ahead and do that by selecting them in the Library and clicking the Trash Can icon at the bottom of the Library panel.
13. Reapply a shape tween, and scrub to frame 10. 14. Select the Free Transform tool, and drag around one of the bounding box corners to change
both the horizontal and vertical scales. If you like, hold down Shift to constrain the aspect ratio, and Alt (Windows) or Option (Mac) to apply changes from the center of the transformation point. Make the pepper a good bit bigger than the original size. This shows that it s possible to adjust keyframes even after they re already part of a tween.
Another way to apply shape tweens is to click between two keyframes and select Insert Shape Tween. To remove a shape tween, select Insert Remove Tween. You ll see that you can do the same with motion and classic tweens.
Modifying shape tweens
There are a couple ways to refine a shape tween once it s applied. These are shown in the Properties panel when you click in a tweened span of frames: Ease and Blend. Easing tends to make tweens look more lifelike because it gradually varies the amount of distance traveled between each frame. If an astronaut throws a golf ball in outer space, the ball flies at a constant rate until...well, until it hits something. That s not how it works on a planet with gravity. The ball flies faster at first and then gradually slows down. This deceleration is called easing out. A ball dropped from a tall building begins its descent slowly and then gradually increases speed. This acceleration is called easing in. Click anywhere between two key frames of a tween, and adjust the Ease hot text in the Properties panel to see how easing affects the shape tween applied to the pepper in the previous exercise. Supported values range from 100 (strong ease out), through 0 (no easing), to 100 (strong ease in). As shown in Figure 7-6, easing can have a profound effect upon an object in motion. We ll cover easing in greater detail in the Classic tweening section.
If you don t see much of a difference after experimenting with easing, try lengthening the duration of your shape tween. To do so, click somewhere in the tween span between the two keyframes, and then press the F5 key several times to insert new frames.
