Using Behaviors

You can keyframe a parameter either before or after applying a behavior to the object
that affects it. When you keyframe a parameter that is already affected by a behavior,
the value of the keyframed curve is combined with the value generated by the
behavior at each frame, which either raises or lowers the resulting value displayed by
the background curve. The background curve doesn’t just display the behavior’s
animated values, it displays the sum of all values affecting that parameter.

Raising or lowering a keyframe in the Keyframe Editor also raises or lowers the
background curve, since it’s modifying the values generated by the behavior.

Important:

The value displayed in the Inspector for the affected parameter reflects the

final combined result of both keyframes and behaviors that are applied to that
parameter. Editing a parameter’s values directly in the Inspector only results in changes
made to the underlying parameter value, whether keyframed or not. This parameter
value is then combined with the behavior’s effect, yielding a final value that may differ
from the value you entered.
