Chapter 2 The Playground 69

It is important to remember that applying a behavior to an object applies a rate of

change to an object’s parameters, and does not create editable keyframes. For fine

tuning, many behaviors can be converted to keyframes. For more information, see

“C

onverting Behaviors to Keyframes” on page 118. You can affect some of the Basic

Motion behaviors in the Timeline.

Stopping the Effect of Basic Motion Behaviors

You can stop the effect of the Basic Motion behaviors in two ways: Change the

duration of the behavior in the Timeline, or apply a Stop parameter behavior to the

parameter that is affected by the behavior. Since the Throw behavior affects the

Position parameter of the lion object, the Stop behavior is applied to the Position

parameter.

To stop the Throw in the Timeline:

1 In the Toolbar, click the Timing icon (in the upper-right corner of the interface).

The Timeline appears. Layers and objects appear as blue bars, and behaviors (as well as

filters) appear as purple bars. To change the duration of an object, you can drag the

end (or beginning) of a bar. Since the duration of the Throw behavior is the length of

the object to which it is applied, trim the Throw behavior bar to stop the Throw before

the end of the object to which it is applied.

2 Click the right end of the Throw behavior and drag toward the left to the frame where

you want the object to stop moving.

The object stops at the frame where the Throw duration bar ends.
