There is now a Latvian translation of the OOP for AS2.0 series of posts available at Flash.lv. Again, links to the translations will be posted in the comments as they are complete.

Thanks to Darklow for doing the translations.

The next entry in the English series should be up early tomorrow morning.

Installment 4 of my series on Object Oriented Programming with ActionScript 2.0 will cover dynamic classes – a relatively simple topic, but one worth being familiar with so as to avoid frustration.

Again, if you haven’t read the previous posts, you should because they all build on one another. Also, if you want all the nitty gritty details, you’ll have to buy “Flash MX 2004 Demystified”, which is forthcoming from Macromedia Press.

By default, the actionscript 2 compiler in FlashMX 2004 will not allow you to add new properties or methods to instances of a class. Attempting to do so will result in a compiler error.

Zooil Yang is translating my Object Oriented Programming with Actionscript 2.0 series of posts into Korean, and posting them to feople.com.

The first two posts are up:

OOP4AS2#1: Classes and instances

OOP4AS2#2: Class members

He will be posting links to other translations in the comments.

Thanks Zooil!

I neglected to mention this important point in OOP4AS2#2 – when creating array or object properties for classes, you must initialize them in your constructor as with “goodList” below. The “badList” array property below will share the same data amongst all instances of the class:

class MyList {
var goodList:Array;
var badList:Array = new Array();
MyList = function() {
goodLlist = new Array();
}
}

Bokel has a good description of the issue, with some sample code here.

Installment 3 will build on the previous 2 parts (so if you haven’t read them already, you should), by taking a look at how to create a constructor function for a class in ActionScript 2.0.

A constructor lets you pass in parameters when you create a new instance of a class, and use those parameters to set properties and carry out operations on the new instance as it’s created.

This has got to be one of the coolest new features in Flash MX2004: Global Search and Replace. Go to Edit, and select “Find…” and you will be shown the new search and replace panel. You can search for virtually any type of asset in your entire FLA: Text (script and/or text content), Images, Sounds, Fonts, etc.

While it still seems a little buggy, and it’s a shame it has no undo capability, or the ability to search on an entire project, it sure will save me a lot of time. I don’t know how much of my short life I’ve wasted hunting in vain for the final occurence of a font in a FLA, trying to eliminate the extra 20kb added to the SWF because I’m using both bold Arial and Arial Bold.

Goodbye Movie Explorer!!

In installment 1, we learned how to define a class in AS2, and how to make instances of that class – if you didn’t read installment 1, you should. Now, we’re going to have a look at how to add members (properties and methods) to our class. We’ll also have a quick look at using strict-typing.
