Chapter 9 Using the Replicator 835
5 At the frame where you want to begin the animation, drag the Location slider (or use
the value slider) to set where the sequence begins.
As you drag the slider, the sequence moves through the pattern elements. Values
displayed in the Location parameter specify where in the pattern the sequence is (in
percentage points)—0 representing the origin of the pattern, and 100% representing
the end of the pattern.
In the Inspector, a keyframe is added to the Location parameter.
6 Go to the next frame where you want to set a keyframe, and move the Location slider.
7 Repeat step 6 until you have created all of your keyframes.
8 Play the project (press the Space bar).
The animation moves through the replicator pattern based on its keyframed locations.
In this case, the scale moves erratically back and forth around the circle, rather than in a
constant direction.
Using Parameter Behaviors With the Sequence Replicator Behavior
Like all other layers in Motion, you can add Parameter behaviors to the Sequence
Replicator parameters to create even more varied, complex effects without keyframing.
To apply a Parameter behavior to a Sequence Replicator behavior:
1 In the Layers tab or Timeline layers list, select the Sequence Replicator behavior.
2 Control-click the parameter to which you want to add a Parameter behavior, then
choose a Parameter behavior from the shortcut menu.
