Using Behaviors
451
HUD Control
The HUD control allows you to change the parameter assignment.
Parameters in the Inspector
Apply To: The Apply To (“Go”) pop-up menu shows the parameter being stopped and
can be used to reassign the Stop behavior to another parameter.
Track
This behavior allows you to apply tracking data to a parameter of an effect, such as the
center point of the Light Rays filter. For more information on using the Track behavior,
Motion Supplemental Documentation PDF.
Wriggle
This behavior works similarly to the Randomize behavior, but with a slower effect.
HUD Control
The HUD lets you adjust the Amount, Multiplier, Frequency, Wriggle Offset, Noisiness,
Link (for multidimensional parameters), Start Offset, and End Offset parameters, as well
as change the parameter assignment.
Parameters in the Inspector
Amount/Multiplier: This parameter is set to Amount when the Apply Mode is set to
Add, Subtract, or Add and Subtract. This parameter is set to Multiplier when the Apply
Mode is set to Multiply. This parameter defines the maximum value that the Wriggle
behavior generates.
Apply Mode: A pop-up menu that determines how values generated by this behavior
are combined with other behaviors and keyframes that affect the same parameter. This
provides you with different ways of using a Wriggle behavior to modify a parameter’s
preexisting values. The options are Add, Subtract, Multiply, or Add and Subtract.
Frequency: A slider that lets you adjust the amount of random variation per second.
Higher values generate faster variations, whereas lower values generate slower
variations.
Wriggle Offset: A slider that allows you to offset the sequence of random values when
you want to apply the same Wriggle behavior to multiple objects. By offsetting each
object’s version of the Wriggle behavior, you can prevent objects from moving in sync.
Noisiness: This slider adds an additional overlay of random variance to the Frequency
you’ve set. Higher Noisiness values result in more erratic variations in the affected
parameter.
