434 Chapter 5 Using Behaviors
To add a parameter you want to animate in a Custom behavior:
m Choose a parameter you want to add to the Custom parameter list from the Add
Parameter pop-up menu. This menu contains every animateable parameter.
The parameter appears in the Behaviors tab below the Custom behavior.
Once you’ve added all the parameters you want to animate in your Custom behavior,
you can keyframe them in the Keyframe Editor to create whatever animated effect you
require. For more information on keyframing parameters to create animation, see
“
Animating Behaviors ” on page 514.
To remove a parameter from the Custom parameter list:
m Choose the parameter you want to remove from the Remove Parameter list.
That parameter no longer appears in the Custom parameter list. Any keyframes that
were applied to that parameter are deleted.
Once you have animated all the parameters you added, you can save the Custom
behavior into the Library for future use. For more information about saving Custom
behaviors to the Library, see “
Saving and Sharing Custom Behaviors ” on page 405.
The new parameter
appears here.
