Unlike the Negate behavior, which inverts the value of the parameter to which it’s applied, the Reverse behavior reverses the direction of any animation that affects a parameter, whether it’s caused by behaviors or keyframes. For example, when you apply the Reverse behavior to path animation that begins at the left and moves to the right, the animation path won’t move, but the object instead begins at the right and moves to the left. The Reverse behavior basically switches the beginning and ending points of animated objects.

Adjust this behavior using the control in the Behaviors Inspector:

  • Apply To: A pop-up menu that shows the parameter affected, and that can be used to reassign the behavior to another parameter.
