了解如何使用“行为”，“关键帧”和“运动跟踪”制作动画
Animating Motion's effects can be easily accomplished by using Behaviors. Behaviors are sets of parameters that you apply to objects to move them, in a myriad of ways, around the frame. In this tutorial Michael Wohl shows you how use these built-in actions and reactions to quickly and easily create complex animations.
Think of Behaviors as object-assignable personality traits that determine how all the different objects in your project conduct themselves in relationship to all the other objects on the screen. By setting up these "rules of behavior" you can quickly create very cool and complex animations that, some years ago, would have taken hours, or even days to produce!
However, there are times when Behaviors just can't get the job done. Keyframing to the rescue! In the final section of this animation tutorial Michael shows you everything you need to know to control your animation with keyframes in Motion 5.
