In 2006, Adobe introduced ActionScript 3.0, which offered significant new functionality
as well as dramatic performance increases. Flash CS3 was the first version
of Flash to incorporate ActionScript 3.0. Flash CS4 added functionality to
ActionScript 3.0, including new 3D capabilities, new animation controls, and
ActionScript classes for working with Adobe AIR (see Lesson 14, “Creating Adobe
AIR Applications with Flash and ActionScript”). Flash CS5 continues the evolution
of ActionScript 3.0 and has added lots of new ActionScript for working with
advanced text features; enhancing the AIR platform; and working with a variety of
devices and controllers, including multitouch and touch-screen devices. Flash CS5
also has a number of new features to help you learn and work with ActionScript,
including the new Code Snippets panel, which lets you reuse common ActionScript
code with the click of a mouse. Other new ActionScript features, such as code
completion and tooltips for custom classes, will show their worth as you begin
working with the language.
