The new object is inserted into the track. The original object bar is split into two bars,
and the frames that follow the inserted object are pushed out later in time.
For more information on using the drop menus, see Chapter 4, “Using the Timeline,” in
Motion Help.
Modifying Behaviors in the Timeline
The Timeline can be an important tool for modifying behaviors. Like objects, behaviors
appear as colored bars in the Timeline, and can be moved and trimmed to define new
start and stop points for the behaviors. With the exception of slip, the same controls
that are used to edit objects and layers in the Timeline are used to edit behaviors. For
information on editing objects in the Timeline, see “
When a behavior is applied to an object, it defaults to the duration of the object to
which it is applied. For example, when the Grow/Shrink behavior is applied to an object
(and set to Grow), the object scales up continually from the first frame of the object to
the last frame of the object. To change the timing of the behavior’s effect on the object,
adjust the duration of the behavior in the Timeline. For example, you can trim the
Grow/Shrink behavior bar so that the grow does not take effect until frame 30.
To change the default duration of a behavior:
1
In the Timeline, position the pointer at the In point of the behavior.
2
When the pointer changes to the Trim tool, drag the bar toward the right to the frame
in which you want the behavior to start.
The behavior does not take effect until the In point of the behavior.
3
Trim the Out point of the behavior by dragging toward the left, to the frame in which
you want the behavior to end.
The behavior’s effect stops at the Out point.
Note: To change the rate of the Grow/Shrink behavior, use the controls in the
Dashboard or the Inspector.
