326 Chapter 5 Using Behaviors
Applying Parameter Behaviors
Parameter behaviors are applied differently than the other types of behaviors. While all
other behaviors are applied directly to an object and affect specific parameters of that
object, Parameter behaviors are applied to an object’s parameter. This also includes the
parameters of filters, emitters and cells in particle systems, and other behaviors that
have been applied to an object. In a simple comparison, a Throw behavior is applied to
an object and that object travels across the Canvas. If an Oscillate Parameter behavior is
applied to the Position parameter of an object, that object moves back and forth across
the Canvas.
A Parameter behavior’s effect on an object depends on the parameter to which it is
applied. For example, if you apply the Randomize parameter behavior to an object’s
Position parameter, that object drifts around the screen when the project is played.
Applying the Randomize parameter behavior to an object’s Scale parameter makes the
object randomly grow and shrink.
To apply a Parameter behavior to an object’s specific parameter:
1 Select an object to which you want to apply the Parameter behavior.
2 Do one of the following:
• Control-click a parameter in the Inspector, then choose a Parameter behavior from
the shortcut menu.
• Control-click a parameter in the Dashboard, then choose a Parameter behavior from
the shortcut menu.
Once a Parameter behavior is applied to a parameter, the Inspector automatically
switches to the Behaviors tab.
Note: If you save a Parameter behavior as a favorite, the parameter to which it was
applied is saved along with the rest of that behavior’s settings. As a result, it can be
applied like any other behavior and that parameter is automatically affected.
