If the behavior was applied to one dimension of a multidimensional parameter, open
that parameter’s disclosure triangle and Control-click the dimensional parameter to access
the same shortcut menu, then choose Stop.
The parameter is animated until the frame where the Stop behavior begins.
Note: When applied in this manner, the Stop behavior takes effect at the current frame
(regardless of the Create Layers At Preference setting).
4 To assign the Stop behavior to a different parameter, choose a new parameter from the
Apply To pop-up menu.
The Stop behavior halts the animation of all behaviors that affect the selected parameter
of that object. For example, if the Gravity, Edge Collision, and Rotate behaviors are applied
to a shape and you apply the Stop parameter to the shape layer’s Position parameter,
the shape stops moving but continues rotating.
To control when animation affecting that parameter is stopped, trim the Stop behavior
in the Timeline. For more information on trimming behaviors, see Trimming Behaviors.
For more information about applying Parameter behaviors, see Applying Parameter
Behaviors.
Trimming Behaviors
When you apply a behavior to an object, the duration of the behavior in the Timeline
defaults to the duration of the object to which it’s applied. However, a behavior can be
modified to limit the duration of its effect. For example, if you apply the Spin behavior
to a replicator layer, by default that replicator spins around for its entire duration. If you
trim the Out point of the Spin behavior, the spinning stops at the new position of the
Out point.
As you trim the behavior, a tooltip appears, indicating the new location of the Out point
as well as the new duration of the behavior.
To change the duration of a behavior in the Timeline
1 Move the pointer to the In or Out point of any behavior in the Timeline.
2 When the pointer changes to the trim pointer, do one of the following:
• Drag the In point to delay the beginning of the behavior’s effect.
