•
Link: A checkbox available when you apply this behavior to a two-dimensional parameter
(such as Distort) or three-dimensional parameter (such as Position or Rotation) that consists of
X, Y, and/or Z values. Select this checkbox if you want the transformation applied to the X and
Y vertices to be the same. For instance, a +10 change to X will result in an identical +10 change
to Y.
•
Preserve Angle: A checkbox that causes the tangent handles become (or remain) flat,
maintaining the continuity of the curves.
•
Random Seed: A button that selects a new random seed number. This number is used to
randomly generate new sequences of values, based on the other parameters of this behavior.
Sequence Paint
The Sequence Paint behavior animates the individual dabs of a paint stroke in sequence over
time. This is the only way to animate the dabs individually—keyframing the stroke parameters or
applying other behaviors affects all dabs in the stroke uniformly.
The Sequence Paint behavior is very similar to the Sequence Text and Sequence Replicator
behaviors, which allow you to animate the Rotation, Color, Opacity, Scale, and Position
parameters in sequence through the characters of a text layer or the elements of a replicator
pattern. The Sequence Paint behavior adds Width to that list of parameters, allowing you to
create sequenced animation through the dabs of a paint stroke.
For an example of using a sequence behavior, see Apply the Sequence Replicator behavior on
page 596.
Parameters in the Inspector
•
Sequence Paint: An activation checkbox that turns sequencing on or off. Before any sequencing
animation can occur, you must add at least one parameter to the behavior in the Inspector,
and then set a value for that parameter. Until a parameter is added, adjustments in the
Inspector or HUD have no effect.
•
Parameter: Add and Remove pop-up menus that add and remove parameters to the sequence.
After you add the parameter, additional controls appear in the Behaviors Inspector. Adjust
those controls to create a sequence animation based on the difference between the original
value of the dabs and the modified value. There are six menu options and related controls:
•
Rotation: Specifies (in degrees) the rotation of the stroke dabs. You can rotate the dial or
use the value slider. Click the disclosure triangle next to the Rotation parameter to reveal
separate X, Y and Z Rotation controls.
•
Color: Specifies a color to tint the stroke dabs. You can click the color well to choose a color,
or open the disclosure triangle and use the Red, Green, and Blue sliders.
•
Opacity: Defines the opacity of the stroke dabs. Set a new value using the slider.
•
Scale: Defines the scale of the stroke dabs. Click the disclosure triangle next to the Scale
parameter to reveal separate X Scaling and Y Scaling subparameters to scale the width and
height of the dabs separately. By default, Scale is set to 100%—the size of the stroke dabs is
equal to the original size defined in the stroke parameters.
