7. When this partner snaps into place, it will turn green. Return to frame 20, and notice that the
original shape hint has turned yellow. It s a dramatic improvement, but there are still a few trouble spots. It may be that shape hints have a thing for stoplights (not that there s anything wrong with that), but the point is that the color change indicates something. It tells you that this shape hint pair has entered into a relationship. You have now indicated to Flash your intentions that these paired regions now correspond to each other.
8. Slide the playhead along the timeline again, and you ll see a remarkable improvement (as shown
in Figure 7-14).
Figure 7-14. It s a dramatic improvement, but there are still a few trouble spots. The improvement is so remarkable, in fact, that the authors look deftly side to side, wink, and silently mouth the word voodoo. To be frank, if we may, the placement of shape hints often makes a noticeable difference, but the decision on placement is something of a dark art. We encourage you to reposition your first shape hint pair at other corners to see how the remaining trouble spots ripple to other areas. You should get the idea by now that shape hints are a bit like cloves (you know, the star-shaped things you poke into your ham during the holidays) a little goes a long way. Let s add a few more, but do so sparingly.
9. To get rid of the kink in the upper curve, add a new shape hint to the upper-right corner of the i
on frame 20. This time, you ll see a small b in a circle. Snap its b partner to the upper-right corner of the logo at frame 35, and drag the playhead again to see your progress.
10. Add shape hints c and d to the lower-left and right corners, and you should see a very smooth
morph along this span of frames.
11. The only problem remaining, if you re a perfectionist, is a slight wrinkle along the bottom of the
egg between keyframes 37 and 55. Remedy this by adding a new shape hint at frame 37. It will start again at a, because this is a new pair of keyframes, and snap in place to the corresponding curve at frame 55.
ANIMATION, PART 1
Compare your work with the LogoMorph.fla file in this chapter s Complete folder, if you like. When you open a file that already contains shape hints, you ll need to take one small step to make them show, because they like to hide by default. To toggle shapes hints on and off, select View Show Shape Hints. Even with the benefit of shape hints, we caution you to keep simplicity in mind. Certain collections of shapes are simply too intricate to handle gracefully. Remember that not every website visitor will have as powerful a computer as yours. It is entirely possible to choke Flash Player through the use of an overwhelming number of anchor points. To see what we mean, open the FlowerWeed.fla file in this chapter s Exercise folder, and drag the playhead along the timeline. The morph isn t especially polished (see Figure 7-15), but it certainly doesn t count as a complete eyesore. Test the SWF (Control Test Movie), and depending on the power of your computer you may see that playback slows or skips during the most complex portions of the tween. If that doesn t happen for you, count yourself lucky! But generally speaking, try to avoid asking this much of your users. Why do we mention this The reason is because it is a bad experience for the user. In the case of this exercise, you are the only user. Now extrapolate this out to the flower being in a banner ad and your bad experience is now being shared by thousands of others.
Figure 7-15. Moderation in all things! Although this transformation doesn t look awful, it nearly chokes Flash Player.
