Global variables

[Leozack]

Another quicky - I'm used to coding where I can declare global variables at the start of a project and any funciton can get/set them. For flash now I'm breaking things into functions, I'm finding myself repeatedly passing things lik ean xml root node to another function. And if a function loads in a bunch of text as part of the function, how will other functions it goes back to ahve access to them? I'm not sure which is the best way to do it in AS o.o

If you're using them in a class, you can make them class-level variables.

public class MyClass
{
    public var MyVar:Object = new Object();

    // Your functions, constructors, etc.
}

Of course, you should use Properties, rather than public variables.

public class MyClass
{
    private var _myVar():Object = new Object();

    public function get MyVar:Object
    { return _myVar; }

    public function set MyVar(value:Object):void
    { _myVar = value;

    // Your functions, constructors, etc.
}

After a quick read there I think I've got it sussed. I'm just using _global.varname to make my variables now and it's replaced the need to keep pasing variables around between all the functions, huzzah

Having done this, I've got another quickie I don't want to waste a new topic on

That being that when I look at the variables that contain text like "characters you'd escape" apostrophies etc, they come out in the textbox as html entities, eg &pos; and I've tried things I can think of lik eunescape() but I dunno AS well enough to know what function to convert them back. What is it? x.x I tried saying .htmltext on the textbox instead of just .text but that didn't help either.
