Chapter 5 Using Behaviors 393
Applying Multiple Behaviors to an Object
There is no limit to the number of behaviors you can add to an object. When multiple
behaviors are applied to a single object, they all work together to create a final
animated effect.
Because each behavior applies a value to a specific parameter, the values generated by
all behaviors that affect the same parameters are combined to create the end result.
For example, applying the Throw, Spin, and Gravity behaviors to a single object results
in the combined result of the Throw and Gravity behaviors affecting the position of the
object, and the Spin behavior affecting its rotation.
Reordering Behaviors
When you apply a number of behaviors to a single object, they all appear nested
beneath that object in the Timeline and Layers tab. You can change the order in which
they are applied. While the effects of most behaviors on a parameter are additive, this is
useful more as an organizational tool than as a way to change the animated effect
created by the behaviors. One notable exception to this is the Stop behavior. It
suspends the activity of all behaviors appearing beneath it that affect the same
parameter, while not affecting any behaviors above it in the Layers list.
To reorder a behavior:
1 Drag the behavior you want to reorder up or down in the list of nested behaviors
applied to the same object. A position indicator shows where the behavior appears
when you release the mouse button.
2 When the position indicator is in the correct position, release the mouse button.
A position indicator appears whenever you
drag a behavior within the list.
