816 Chapter 9 Using the Replicator
You can also use keyframes to animate the parameters in a replicator’s Properties tab.
Parameters in this tab affect the replicator as a whole, not the individual replicator
elements. This can be useful for changing the replicator’s position or rotation over time.
Example: Creating an Animated Replicator
The following example demonstrates how quickly you can create attractive, complex
animated patterns with minimal effort. An animated replicator is created using a hand-
drawn shape as the source for the replicator’s cell. Once the replicator is created, the
Angle and Scale parameters are keyframed, and a Parameter behavior is applied to the
Radius parameter.
To create an animated replicator using keyframes:
1 Place the object that you want to replicate into your project.
This example uses a bow-shaped Bezier shape object that is filled with a custom
gradient. (You can also use a shape with the default white fill, and apply a gradient to
the replicator elements rather than the original source object.)
2 In the Layers tab, select the source layer and click the Replicate icon in the Toolbar (or
press L).
The default replicator object (rectangle shape with the tile fill arrangement) appears in
the Layers tab and in the Canvas. The original source layer is disabled.
