Although you can animate shapes in your project by applying standard behaviors, a special category of behaviors is designed for use with shapes and their parameters.
There are nine Shape behaviors:
Apply Pen Pressure maps stylus pressure to width, opacity, spacing, jitter, and other parameters when you draw a paint stroke with a Wacom tablet.
Apply Pen Speed maps stylus speed to width, opacity, spacing, jitter, and other parameters when you draw a paint stroke with a Wacom tablet.
Apply Pen Tilt maps stylus angle to width, opacity, spacing, jitter, and other parameters when you draw a paint stroke with a Wacom tablet.
Oscillate Shape animates a shape by cycling its control points between two values.
Randomize Shape animates a shape by applying a random offset to each control point.
Sequence Paint animates the individual dabs of a paint stroke in sequence over time.
Track Points pins the control points of a shape or mask to a moving clip or animated object.
Wriggle Shape animates a shape with an effect similar to the Randomize Shape behavior, but more slowly.
Write On draws a paint stroke or shape outline in the Canvas over time.
You apply a Shape behavior the same way you apply standard behaviors to any object in Motion. And after you apply a Shape behavior, you can modify its parameters in the Behaviors Inspector to create highly customized animations.
Note: For general information about animating with behaviors, see Behaviors overview.
