You can also use the Tween and TransitionManager classes outside of a screen-based
document, in either Flash Basic 8 or Flash Professional 8. For example, you can use the classes
with the component set of version 2 of the Macromedia Component Architecture, or with
movie clips. If you want to change the way a ComboBox component animates, you can use
the TransitionManager class to add some easing when the menu opens. Easing refers to
gradual acceleration or deceleration during an animation, which helps your animations appear
more realistic. You can also use the Tween and TransitionManager classes, instead of creating
motion tweens on the timeline or writing custom code, to create your own animated
menu system.
The Tween and TransitionManager classes are available only in ActionScript 2.0, but
these classes are available in both Flash Basic 8 and Flash Professional 8.
For information on each method and property of the Tween class, see Chapter 51, "Tween
class" in the Components Language Reference. For information on each method and property of
the TransitionManager class, see Chapter 48, "TransitionManager class" in the Components
Language Reference. For information on working with packages, see
packages" on page 499.
