Macromedia Flash Mx 1002004 Actionscript Training From The Source [Electronic resources] نسخه متنی

Lesson 2. Using Event Handlers

We push buttons, we push people, we even push people's buttons, all with a single purpose: to elicit a response. The Macromedia Flash way of saying this is that for every event there is an action.

In a Flash environment, the responses that come from pushing, holding, moving, entering, and leaving are triggered by event handlers. Event handlers represent the first step in getting your movie to do anything interactivewhich is why a thorough understanding of them is vital.

We'll create several projects in this lesson, including this self-running presentation that uses frame events to provide the user with a hands-free experience.
