Understanding objects in ActionScriptI attended a Macromedia Flash MX seminar earlier this year (2002), at the end of which, Macromedia's representative asked the audience of designers and developers whether they understood the term "Object Oriented Programming"? Almost nobody in the room was confident enough to raise their hand. The basic animation techniques and predefined Macromedia methods in ActionScript are relatively easy for a beginner to pick up and teach themselves how to make interactive movies. This means that most Flash Developers are self-taught and pick up a lot of bad habits along the way. This tutorial introduces concepts which I use in my work, programming Flash-based software for e-learning projects.What is an object?Objects are used in Flash to created structured movies. Objects can be embedded within other objects. Object in Flash have properties and methods. How to initialise an object
myObj = new Object();
myObj = {};
this.myObj = {};
These examples all produce the same result, they create an object called myObj within the current MovieClip object timeline. If this code was written your movie’s main _root timeline then myObj would be a child of your main movie. The object created in these examples inherits the class of Object – a predefined Macromedia class. A class contains the initial properties and methods to apply to the new object.
