Instruction Manual

Chapter 20 Shapes, masks, and paint strokes 879
•
End: A slider, available when Unit Size is set to Custom, that sets the ending point for the dabs
on the stroke aected by the animation.
•
Spread: A slider that, when increased, creates a softer transition between dabs. (This parameter
is not available when Unit Size is set to All.)
•
Traversal: A pop-up menu that sets the action of the sequence behavior to any of the
following options:
•
Constant Speed: Moves the animation from the origin of the paint stroke through the end of
the stroke at a constant speed.
•
Ease In: The sequence animation begins slowly and increases to normal speed as it moves
through the paint stroke.
•
Ease Out: The sequence animation begins at normal speed and slows toward the end of the
paint stroke.
•
Ease In/Out: The sequence animation begins slowly, increases to normal speed as it moves
toward the middle of the stroke, and slows as it reaches the end of the paint stroke.
•
Accelerate: The sequence animation increases in speed.
•
Decelerate: The sequence animation decreases in speed.
•
Custom: Lets you keyframe how the animation moves through the paint stroke. When you
choose Custom from the Traversal pop-up menu, the Location parameter replaces the
Loops parameter.
•
Loops: A slider that 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.
•
Location: A slider, available only when Custom is selected from the Traversal pop-up menu,
that denes the location of the stroke where the animation is in eect.
For more information on using the Custom Traversal option, see Use the Sequence Replicator
Custom Traversal option on page 605.
•
End Condition: A pop-up menu that determines how the sequence animation is repeated over
the duration of the sequence behavior. This parameter has no eect 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 (after 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 rst dab.
•
Ping Pong: Completes the sequence animation cycle forward, then completes the animation
backward, then forward, and so on.
Track Points
This behavior lets you 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 Track Points on page 958.
