402 Chapter 5 Using Behaviors
You can convert the behaviors that are applied to all parameters of an object into
keyframes. Converting behaviors that have already been combined with keyframes
turns the sum of all behaviors and keyframes affecting that parameter into a thinned
series of keyframes (a curve with less keyframes). This results in a final animation curve
that closely replicates the shape of the background curve that appeared in the
Keyframe Editor. These keyframes can then be edited directly in the Keyframe Editor.
For more information on converting behaviors into keyframes, see “ Converting
Behaviors to Keyframes ” on page 404.
Animating Behavior Parameters
You can animate most behavior parameters in order to change the parameter’s effect
over time. You can animate behavior parameters using parameter behaviors, or by
keyframing them in the Keyframe Editor.
