Summary: 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.
