1070 Chapter 12 Using Shapes and Masks
When the Randomize Shape behavior is applied to a shape, all control points of the
shape are affected by default. When the behavior is selected in the Layers list, affected
control points appear white. To disable one or more control points, click the control
points. A disabled point appears blue. Drag to select the points to select multiple
control points.
The Randomize Shape HUD contains the Amount, Multiplier, Apply To, Frequency,
Noisiness, Link, and Preserve Angle parameters. These controls, and the additional
parameters in the Inspector, are described below.
Parameters in the Inspector
Amount/Multiplier: This parameter is set to Amount when the Apply Mode is set to
Add, Subtract, or Add and Subtract; it is set to Multiplier when the Apply Mode is set to
Multiply. This parameter defines the maximum value the Randomize behavior will
generate.
Apply To: A pop-up menu that defines whether the behavior is applied to the shape’s
control points, tangent handles, or both points and handles.
 Points: The control points of the shape are randomized, changing their position over
the duration of the behavior.
 Tangents: The control points’ tangent handles (rather than the control points) of the
shape are randomized. The control points stay in a fixed position while the curves in
between the points are animated.
 Points and Tangents: Both the control points and handles are animated.
The white control point is enabled and
affected by the behavior.
The blue control points are disabled and not
affected by the behavior.
