Chapter 5 Using Behaviors 325
2 Do one of the following:
• In the Toolbar, click the Add Behavior icon, then choose a behavior from one of the
submenus.
• Select a behavior in the Library, then click Apply in the Preview area.
3 Play the project to see the animated effect in action.
Note: Not all behaviors automatically create motion on an object. Some behaviors,
such as Throw, require you to set the throw velocity (in the Dashboard or in the
Inspector) before the object is “thrown.” Other behaviors, such as Orbit Around, require
a source object to be specified for that object to move around.
When a behavior is applied to an object, the object parameters affected by that
behavior are automatically animated based on the behavior’s default settings. For
example, if you apply the Gravity behavior to an object in the Canvas, then play the
project, that object’s position is animated and it moves down, according to the Gravity
behavior’s default setting.
Note: You can also apply behaviors directly to layers in the Layers tab or Timeline.
Depending on the applied behavior, all objects nested within that layer are either
affected as if they were a single object or as individual elements. You can often change
this result by adjusting the Affect or Affect Object parameter.
Tip: If you do not see the expected result when applying behaviors to objects, try
turning the Affect Objects parameter on or off, or selecting a different option from the
Affect pop-up menu. These parameters determine whether the entire object (such as a
layer) or its components (such as the child objects nested within that layer) are affected
by the behavior and how an object interacts with surrounding objects, respectively.
Note: The Affect Objects checkbox only appears in the Inspector when the Throw and
Spin behaviors, or the Simulation behaviors, are applied to an object that contains
multiple objects, such as a layer, particle emitter, or text.
Removing Behaviors
Since behaviors don’t add keyframes, removing a behavior instantly eliminates its
animated effect. All types of behaviors are removed in the same way.
To remove a behavior from an object:
1 Select a behavior in the Layers tab, Timeline, Behaviors tab, or pop-up menu in the title
bar of the Dashboard.
2 Do one of the following:
• Choose Edit > Delete.
• Control-click the behavior in the Layers tab or Timeline, then choose Delete from the
shortcut menu.
• Press Delete.
