Flash - ActionScript - Syntax

scripting syntax

* the dot operator (.) provides a way to access the properties and methods of an object. Type the instance name, followed by a dot, and then the name of the property or method. Think of the dot as a way to separate objects, methods and properties.

* whenever you are entering a string or the name of a file, use quotation marks

Flash - ActionScript

Adobe Flash CS5 uses Action Script 3.0, which is a robust scripting language, that can be used to extend the functionality of Flash.

ActionScript, which is similar to JavaScript, allows you to add more interactivity to Flash animations.

You can use ActionScript to attach behaviors to buttons.

You can also use ActionScript to perform simple tasks like stopping an animation..

Flash - Notes - Chap.6 Classroom in a book

In Flash, you use ActionScript to achieve most interactivity.

ActionScript provides the instructions that tell each button what to do when a user click on one of them.

In chapter6, you will learn to create a "non-linear navigation", where a movie does not neccessarily have to directly play from beginning to end.--> Action script can tell the Flash playhead to jump around and go to different frames of the Timeline based on which button the user clicks. Different frames on the timeline contain different content. The user doesnt actually know that the playhead is jumping around the tmeline: the user just sees (or hears) different content appear as the buttons are clicked on the Stage.
