ActionScript 3.0 :: Using Static Variable To Create External Classes?
Feb 25, 2011
I've rarely used static variables or methods when creating external classes, but I have on occasion, and it's very useful when I need global access to a value. I've seen negative criticism on the use of the "static" keyword, but never understood why. Is there a right and wrong way of using it, or is this not true? I'd like to use it in a context similar to classes such as MouseEvent or TextFieldAutoSize, where there is a list of values globally accessible for identification purposes.
It allows better code readability, and also allows for easy customization in the future. The value of TextFieldAutoSize.NONE is "none", but as long as a programmer used the reference TextFieldAutoSize.NONE and not the string literal "none", Adobe could change the value of TextFieldAutoSize.NONE to be "hahahahaha" and everything would still work just dandy because (TextFieldAutoSize.NONE == TextFieldAutoSize.NONE) is still true even though ("none" == "hahahahaha") is not.
Is there any kind of negative impact on using static variables this way? Or even functions for that matter? I'd just like to clarify this before I go and build a large project around the idea this is perfectly okay.

Yesterday I found myself wondering, what is the difference between either having a class with methods that are all static, or simply giving your class the static attribute?

At the moment, my main classes game variable, is static, so I can access any class in the game, from any class in the game. However I keep getting errors related to the fact it is static; is there any alternative to this?

I have a Flash application that creates a sort of powerpoint presentation. All the 'slides' are stored in an XML files which is read and processed.
I'm trying to build the presentation using this XML file. At the moment, my main class has it's initial function main and a static function processXML main initiates my database class with a function called initDB. One of my issues is that initDB forgoes processing because it's dependant on an event listener. On completion of loading the XML files, the event listener initiates my static function on my main to create objects from this file.
The issue is that because the event listener continues the processing (after an indeterminate amount of time), the functions are no longer controlled by the main class.

How do Static classes work in projects where child swf's use the same Static class as their parent?
For simplicity... lets say we have some older content swf files that are using TweenLite version 8 ( a common enough Static class.) But the parent SWF is being updated and uses a more recent version of TweenLite (version 10). The child SWF's are loaded into the parent SWF. Do the child SWF exist in there own sandbox and have TweenLite version 8 running and the Parent runs it's own copy of TweenLite 10? Or does the parents clips Static class of TweenLite (version 10) overwrite the children Static class using some sort of magical shared memory space when JIT (runtime) compiling?

I have a movieclip (listBtn) defined in my document class and need to use it in my view class to dynamically create multiple instances of it in a loop. For some reason I'm getting 1180: Call to a possibly undefined method listBtn but can't figure out why since the listBtn is defined as you can see in the view class [code]...

I load many classes in at runtime from external SWF's, accessing those classes is pretty simple, like so -
var currentDomain:ApplicationDomain = ApplicationDomain.currentDomain;
var modelClass:Class = currentDomain.getDefinition(className) as Class;
var model:Model3D = new modelClass();
However I've never tried to access static functions from a runtime class, and now I need to. How is it done? It seems like something that should be simple, but I haven't worked it out yet.

The Idea is i want to make avariable that stores his value after i close the swf and open ti again,
an example:
i make acounter
var i:int = 0;
var timer:Timer = new Timer(1000);
timer.start();
[Code]....
the value of i will increase but after i close the application and open it again the value will return to 0 , keep the variable stores his value after closing the application ?

I have a question about classes. I just learn that static means that functions and/or properties are specifics to a class, but is it a synonym of private? And why statics (not available to any instances?) properties and/or methods can have a public (available anywhere else (timeline)) access modifier? PS: I just start with classes.

i'm trying to learn about clases, and i tried to make an easy XML loader, but i gotta a problem with the attributes that doen't take the value i provide with the att variable. it shows me on the trace statement like undefined, and for example if i change the atrribute instead of being dynamic, to be static, it does work.
Code:
class XMLS {
function XMLS(Path:String, textfield:TextField, att:String, n:Number) {
var miXML:XML = new XML();[code].....

So i have an external text file organized like this:
/* $file: data.txt */
&title0=Sacrum
&detail0=Detail text for Sacrum
&title1=L5
[Code].....
There are 28 of these 'title' and 'detail' pairs. The 'title' text is to fill a dynamic text box and the 'detail' to fill another dynamic text box depending on which section the user is mousing over.
My issue is getting the text from the file stored into arrays. For my test loop I keep getting undefined as the stored value, and i know it has something to do with converting a string value to object..
var lv:LoadVars = new LoadVars();
lv.onLoad = handleDataLoad;
lv.load('data.txt');
function handleDataLoad (success:Boolean) {

I have a site with ScrollPanes, that are calling a Class on what to display. (so the movieclip that I want displayed in the ScrollPane has a Class name.) Within that movieclip (webScroll) that is being displayed in the scrollpane, I have 2 other movieclips (web1 & web2), with unique instance names and eventlisteners targeting those instances. when I preview my site, i get this error: 1119: Access of possibly undefined property web2 through a reference with static type Class.

f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".

I have a class named Locator that I use to GeoLocate a user. There's a static method in that class called "locate()". This method then calls another method which sets a static variable called "loc" to an instance of a LngLat class.The issue I'm having is, when I call the locate method at Frame 1 on the scene, and then try to access the loc variable it shows as null... but when I trace the loc variable after it's set in the Locator class it shows as an object.[code]and then trace the variable at the end of the static method in the Locator class it shows as a object and the city is traced as expected.

It is possible to call variables using this[ "stringname" ] for instance, to refer to a variable called "stringname".
However, when referencing a static variable by the name "stringname", the "this" attribute no longer works if applied.
Is it possible to use this technique with statics?

Code:

public class Factory

A break point on the "Okay" line shows that x1 is null but x2 is equal to "<entity id="DRONE" points="100"/>".
If I take the whole block out of the switch statement, both x1 and x2 are equal to the expected xml.

I'm trying to change a static variable in the class's constructor. At the start I have:
public static var mainReference:Main;
public static var timerReference:Timer;
public var timer:Timer = new Timer(1000);
This is so my static functions can access main and timer. At Main's constructor I have:
mainReference = this;
timerReference = timer;
The problem is, the first gives no error when I compile it, but the second tells me Access of undefined property (timerReference).

Is there any way that you can have dynamic variables inside of a static function considering that you can't use "this" inside a dynamic function.
What I am trying to do:
public static function convertToDynamicString(pString:String):String
{
if(pString == "" || pString == null) return "";

I am accessing the variable in different modules that are loaded, so they are all in their own separate .swf file.
