Chapter 5 Using Behaviors 335
To reorder a behavior:
1 In the Inspector, Timeline, or Layers tab, select the behavior you want to reorder.
2 Drag it 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.
3 When the position indicator is in the correct position, release the mouse button.
Changing the Timing of Behaviors
You can change a behavior’s timing to control when it starts, how long it lasts, and
when it stops. There are several ways to do this. You can use the Stop parameter
behavior to suspend one or more behavior’s effects on a single parameter. You can also
trim each behavior in the Timeline. Finally, you can change some behaviors’ Start Offset
parameter to delay their beginning, and their End Offset to end the behavior prior to
the end of the object to which they are applied. This includes the Fade In/Fade Out,
Grow/Shrink, and Motion Path behaviors.
Using the Stop Behavior
The easiest way to control behavior timing is to use the Stop parameter behavior. The
Stop behavior halts the animation occurring in any one parameter, whether it’s due to
keyframes in the Keyframe Editor, or behaviors that have been applied to that object.
To stop a parameter from animating with the Stop parameter:
1 Select an object, then open the Properties tab in the Inspector.
2 If the Create Objects At preference is set to Current Frame, move the playhead to the
frame where you want animation to stop.
3 Control-click the parameter you want to stop, then choose Stop from the shortcut
menu.
4 Open the Inspector and click the Behaviors tab to reveal the Stop behavior’s Apply To
parameter, then choose a parameter to stop.
The Stop behavior halts the animation of all behaviors that affect the selected
parameter of that object. To control when animation affecting that parameter is
stopped, trim the stop behavior in the Timeline. For more information on trimming
behaviors, see the next section on page 336.
A position indicator appears whenever you
drag a behavior within the list.
