2 Do one of the following:
In the toolbar, choose a behavior from the Add Behavior pop-up menu.
Select a behavior in the Library, then click Apply in the preview area.
Important: Not all behaviors apply motion to an object. Some behaviors, such as Throw,
require you to set the throw velocity (in the HUD or in the Inspector) before the object
is “thrown.” Other behaviors, such as Orbit Around, require a source object to act as the
central object for other objects to move around.
When a behavior is applied to an object, the object parameters affected by that behavior
are animated based on the behaviors default settings. For example, if you apply the
Gravity behavior to an object in the Canvas, that objects position is animated and it
moves down, according to the Gravity behaviors default setting.
Default Behavior Duration
In most cases, a behavior’s duration is the Timeline duration of the object to which it is
applied. For example, if you apply a Spin behavior to an object that begins at frame 20
and ends at frame 300, the Spin behavior’s duration is also frame 20 to frame 300. For
information on trimming the duration of a behavior, see Trimming Behaviors.
Removing Behaviors
Because 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 list, Timeline, Behaviors Inspector, or pop-up menu in the
title bar of the HUD.
2 Do one of the following:
Choose Edit > Delete.
Control-click the behavior in the Layers list or Timeline, then choose Delete from the
shortcut menu.
Press Delete.
Applying Parameter Behaviors
Although all behaviors affect parameters of the objects to which theyre applied, Parameter
behaviors are applied to specific parameters of your choosing.
This includes the parameters of filters, emitters and cells in particle systems, shapes, text,
and so on. You can even apply Parameter behaviors to the parameters of other behaviors
applied to an object.
