Actionscript 3 guide to constants and variables.

This article assumes you have a knowlege of Classes and instances.

public class Cow extends Mammal {
	protected static const NUM_LEGS:uint = 4;
}

Let's dissect this cow, specifically, the NUM_LEGS constant.

There are 6 parts to this declaration:
protected
static
const
NUM_LEGS
:uint
4

I'm going to explain them backwards in order to go from simplest to most complicated.

This is a beginner's guide to E4X.
Flash has some good documentation on using E4X at:
http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/index.html?XML.html&class-list.html,
but it's hard to digest all that if you're just getting started.

You can download the example attached below and follow along.

Loading xml

Before we begin parsing any xml, I'll explain briefly how to load the xml.

Attached below is a utility class with 3 static methods:

• clone
• compare
• mergeObjects

Clone lets you copy Objects and Arrays. If you copy a different class, the public properties (and recursive public properties) will get transferred, but the private properties won't. Also, the cloned object can only be of type Object or Array.

Compare lets you compare recursively the public properties of two objects or arrays. Useful for multi-dimensional arrays.

Localization, Internationalization, or I18N, whatever you want to call it, is just a way to separate your text from your interface so that it can be translated and/or maintained apart from your application.

There are many benefits to this, even if you never plan on having your application in multiple languages. Localization makes your program more maintainable, easier to update, and more flexible to change.

Here's how to localize your content in Flash. It's a lot easier than you might think!

First, open your strings panel:
