Flash CS5: The Missing Manual

Chapter 8. Advanced Tweens with the Motion Editor

Tweens have always been a big tool in Flash’s animation toolbox, and, as explained in Chapter 3, these days you have more control over tweens than ever. Flash’s motion tween (Making It Move with Motion Tweens) can do more than just show a car moving down a street—it can make the car stretch out and turn blazing red when it’s going really fast and scrunch up when it stops. It can even make the car’s shadow change position as the car and sun move across the screen.

You accomplish these sophisticated tweens by making multiple property changes at multiple points in time. Want precision control over every aspect of a tween? Turn to the Motion Editor. This chapter shows you in detail how to apply and fine-tune your motion tweens, focusing in particular on Motion Editor control. You’ll start with a refresher on motion presets, which are simply predesigned tweens that you can apply to objects with a couple of mouse clicks. Then you’ll learn some of the different ways you can edit your tweens on the stage, in the timeline, and using the Motion Editor. Along the way, you’ll learn how to apply filters for special effects and how to create more realistic motion (easing).
