Using Shapes and Masks
When the Oscillate 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 multiple control points.
The Oscillate Shape HUD contains the Wave Shape, Phase, Amplitude, Speed, and
Alternate Phase parameters. These controls, and the additional parameters in the
Inspector, are described below.
Parameters in the Inspector
Wave Shape: A pop-up menu that lets you select the shape of the oscillation’s wave.
The options are Sine (default), Square, Sawtooth, and Triangle. For more information on
wave shapes, see “
Phase: A slider that lets you adjust the point of the specified oscillation at which the
behavior starts. This parameter allows you to put multiple shapes with identical
Oscillate behaviors out of phase with one another so that they don’t all look the same.
Amplitude: A slider that lets you adjust the maximum values that the control points
oscillate between. The control point swings between the amplitude values, and the
negative of the amplitude value. Higher values result in more extreme swings from the
beginning to the ending of each oscillation.
Speed: A slider that lets you adjust the speed at which the oscillation occurs, in
oscillations per minute. Higher values result in faster oscillations.
Alternate Phase: When this checkbox is selected, the motion of each control point is
offset by a phase of 180 degrees from its neighboring control point.
Oscillate Around: This pop-up menu allows you to define whether the oscillation for
each vertex is generated from a point or a perpendicular line.
