Audio behavior in Motion
The Audio behavior lets you animate nearly any parameter based on properties of an audio
file, such as bass frequency. For example, the Audio parameter behavior can be applied to
the Scale parameter of an object, causing the object to scale up and down based on the
amplitude of the bass. See Apply the Audio parameter behavior in Motion.
Average behavior in Motion
The Average behavior smooths the transition from one value to another in animations that
are keyframed and in behaviors that are applied to a parameter. Use the Average behavior
to smooth out animated effects. Averaged motion moves more fluidly, while averaged
changes to parameters such as Opacity and to filter parameters appear to happen more
gradually. Use the Window Size parameter to adjust the amount of smoothing applied to
the affected parameter.
Tip: The Average behavior can be used to smooth out the sequence of values generated
by a Randomize behavior.
Adjust this behavior using the controls in the Behaviors Inspector:
Window Size: A slider that adjusts the amount of smoothing applied to the affected
parameter, by specifying the number of adjacent frames to average together. Higher
values apply more smoothing by averaging a wider range of values, resulting in more
fluid animation. Lower values average a narrower range of values, resulting in less
smoothing, with values closer to the original.
Apply To: A pop-up menu that displays the parameter affected. You can also use this
control to reassign the behavior to a different parameter.
Clamp behavior in Motion
The Clamp behavior sets a minimum and maximum value for an animated parameter. In
the following image, the center star has an applied Vortex behavior set to affect the two
airplane shapes. As a result, the airplanes circle around the center star, as indicated by the
red animation paths.
