Loops: Sets the number of times the animation sequences through the paint stroke
over its duration.
Note: Loops is not available when the Traversal parameter is set to Custom.
End Condition: Determines how the sequence animation is repeated over the duration
of the sequence behavior. This parameter has no effect for Loop values less than or
equal to 1. The End Condition options are:
 Hold: Completes the sequence animation cycle one time, then starts it over again
from the beginning (once the last dab in the sequence has completed its animation).
 Wrap: Treats the sequence animation as a continuous loop so the spread wraps from
the last dab in the sequence to the first dab.
 Ping Pong: Completes the sequence animation cycle forward, then completes the
animation backward, then forward, and so on.
Track Points
This behavior allows you to either track the control points of a shape or mask to a
moving clip or animated object, or to apply existing tracking data to a shape or mask.
For information on using the Track Points behavior, see “
Motion Tracking ” in the Motion
Supplemental Documentation PDF.
Wriggle Shape
This behavior works similarly to the Randomize behavior, but with a slower effect (think
of a shape that’s had one too many espressos before dance class). It also allows for a
greater range of possible values.
When the Wriggle 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 Wriggle Shape HUD contains the Amount, Multiplier, Apply To, Frequency, Wriggle
Offset, Noisiness, Link, and Preserve Angle parameters. These controls, and the
additional parameters in the Inspector, are described below.
