Behavior effects in the Keyframe Editor
If you open the Keyframe Editor and look at a parameter affected by a behavior, you see a
noneditable curve that represents the behavior’s effect on that parameter. The noneditable
curve (in this example, position channel animation that corresponds to the Oscillate
parameter behavior) appears in addition to that parameter’s editable curve, which can be
used in combination to keyframe that parameter. For more information about the Keyframe
Editor, see Display the Keyframe Editor in Motion.
Note: Use the pop-up menu above the Keyframe Editor to select which parameters are
displayed and to create curve sets. For more information on curve sets, see Create a
custom curve view in Motion.
Add or remove a Parameter behavior in Motion
A standard behavior is applied to an object and typically affects multiple parameters of that
object. However, the special class of behavior known as the Parameter behavior is applied
to a specific parameter of your choosing. In this way, you can modify a single parameter
belonging to a filter, particle system, shape, text, or any other object in your project. You
can even apply a Parameter behavior to a parameter of another behavior.
A Parameter behavior’s effect on an object depends on the parameter to which it is
applied. For example, if you apply the Randomize parameter behavior to a particle emitter’s
Position parameter, the emitter drifts randomly around the screen when the project plays.
Applying the Randomize parameter behavior to a shape’s Scale parameter makes the shape
randomly grow and shrink.
