Using the Replicator
697
As previously noted, the replicator also has a special behavior called Sequence
Replicator, which allows you to animate the individual cells in sequence over time. For
more information on the Sequence Replicator behavior, see “
For more information on applying Parameter behaviors to the Sequence Replicator
behavior, see “
Using Parameter Behaviors With the Sequence Replicator Behavior
To apply a behavior to a replicator, do one of the following:
m
Drag a behavior from the Library onto a replicator in the Canvas, Layers tab, or
Timeline.
m
Select the replicator in the Layers tab, Timeline Layer list, or Canvas, click the Add
Behavior icon in the Toolbar, then choose a behavior from the shortcut menu.
The behavior is applied to the replicator, which begins to move according to the
parameters of the behavior.
Not all behaviors instantly activate an object when applied. For example, when a Throw
behavior is applied to an object, the Throw Velocity parameter must be adjusted before
the object moves.
For more information on behaviors, see “
Special Behavior Considerations
When Simulation behaviors, as well as the Spin and Throw behaviors, are applied to a
replicator that has animated parameters, some of the animation created by the
keyframes is ignored. For example, if the Angle parameter in the Cell Controls of the
Replicator tab is keyframed so that the pattern elements rotate over time and you
apply a Spin behavior—with the Affect Objects checkbox turned on (default)—the
elements rotate according to the rate set in the Spin behavior parameters, and ignore
the replicator’s Angle keyframes. To rotate the entire replicator object and enable the
Angle keyframe animation, turn off Affect Objects in the Spin parameters.
Simulation Behaviors and Keyframes
A good rule to keep in mind is that any Simulation behavior, as well as the Throw and
Spin behaviors (Basic Motion), applied to a replicator disables all animation that
affects the position or rotation or the individual elements.
To return to any keyframed animation that was created before you applied the
behavior, simply disable the behaviors. To disable a behavior, turn off its checkbox in
the Inspector, Layers tab, or Timeline Layer list.
