A Parameter behavior is applied to a specific object parameter, and the effect is limited to just that parameter. You can apply the same Parameter behavior to different parameters, resulting in different effects. For example, you can apply the Oscillate behavior to the opacity of an object to make the object fade in and out, or you can apply the Oscillate behavior to the rotation of an object to make the object rock back and forth. You can also apply Parameter behaviors to filter parameters, generator parameters, the parameters of particle systems, or even the parameters of other behaviors.
There are 18 Parameter behaviors:
Audio links any parameter to the dynamic sound properties of an audio file.
Average smooths animation transitions.
Clamp restricts an animated parameter to a minimum and maximum value.
Custom lets you make your own behaviors.
Exponential modifies the speed of animations to create more organic effects.
Link synchronizes the value of one parameter to that of another parameter.
Logarithmic modifies the speed of an animation to create more organic effects.
MIDI lets you edit and animate parameters using a MIDI controller.
Negate inverts a parameter value to its opposite.
Oscillate animates a parameter by cycling it between two values.
Quantize modifies an animation to make parameter values change in incremental steps.
Ramp creates gradual changes in animations.
Randomize creates jittery animations by applying a continuous sequence of randomly increasing and decreasing values.
Rate increases a parameter over time.
Reverse reverses the direction of an animated parameter.
Stop abruptly suspends the animation of a parameter.
Track applies motion-tracking data to a parameter of an effect (a filter, for example).
Wriggle creates jittery animations, but with a slower effect than that of the Randomize behavior.
