A position indicator shows where the behavior appears when you release the mouse
button.
Position indicator
shows where you are
moving the behavior.
2 When the position indicator is in the correct position, release the mouse button.
Note: Motion has a specific order of operations for keyframes and behaviors. For more
information, see Behavior Order of Operations.
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 a behavior’s effect on a single parameter. You can also trim each behavior in the
Timeline. Finally, for some behaviors, you can change the Start Offset parameter to delay
their beginning, and you can change the End Offset to stop the behaviors before the end
of their object duration in the Timeline. These behaviors include Fade In/Fade Out,
Grow/Shrink, and Snap Alignment to Motion.
Using the Stop Behavior
The easiest way to control behavior timing is to use the Stop behavior (in the Parameter
category). The Stop behavior halts the animation occurring in any one parameter, whether
the animation is based on keyframes in the Keyframe Editor or behaviors applied to that
object.
As explained in Applying Parameter Behaviors, all Parameter behaviors can be applied
to a parameter of an object (such as opacity or position) or to an object (such as text or
an image). If the behavior is applied to an object, you must assign a specific parameter
to the behavior (in the Behaviors Inspector).
To stop a parameter from animating
1 Move the playhead to the frame where you want animation to stop.
2 Select the affected object, then open the Properties Inspector.
3 Control-click the parameter to stop, choose Add Parameter Behavior from the shortcut
menu, then choose Stop.
