Learn about the relationships among events, triggers, and effects. Learn about two different ways to write ActionScript code to play effects. One way calls the setStyle method on the target component passing an effect trigger and an effect as parameters to the method. The other way creates an Effect object targeted to the component and calls the play method on the object. Also learn how to play multiple effects in parallel or in sequence.

All references to ActionScript in this lesson are references toversion 3 or later.

This tutorial lesson is part of a series of lessons dedicated to object-oriented programming (OOP) with ActionScript.

Several ways to create and launch ActionScript programs

There are several ways to create and launch programs written in the ActionScript programming language. Most of the lessons in this series willuse Adobe Flex as the launch pad for the sample ActionScript programs.

An earlier lesson titled The Default Application Container provided information on how to get started programming with Adobe's Flex Builder 3. (See Baldwin's Flex programming website .) You should study that lesson before embarking on the lessons in this series.

Some understanding of Flex MXML will be required

I also recommend that you study all of the lessons on Baldwin's Flex programming website in parallel with your study of these ActionScript lessons. Eventually you will probably need to understand both ActionScript and Flex andthe relationships that exist between them in order to become a successful ActionScript programmer.

Will emphasize ActionScript code

It is often possible to use either ActionScript code or Flex MXML code toachieve the same result. Insofar as this series of lessons is concerned, the emphasis will be on ActionScript code even in those cases where Flex MXMLcode may be a suitable alternative.
