Is there any advantage to deleting vars instantiated within public or private functions in a class, or are they removed from memory after the function has been invoked/run? The function below is completely arbitrary for example:
Code:
private function someFunctionHere(_ar:Array):Void {
var _swf:String = _ar[0];
var _nm:String = _ar[1];
[Code]....

it doesn't seem like you can use locally scoped vars within a static block?For example I was thinking I could do:
Code:
public static var standardAgeRange:ArrayCollection = new ArrayCollection();
//static block
{
[code]....
but apparently I have to first declare _n as a static var of my class (or as a static var within the block itself) in order to use it within the static block.needed to do...
private static var _n:int = 2;
then in the static block:
for (_n=2; _n<120; _n++)
In Java I'm able to use locally scoped variables within the static block. I know this isn't Java, just wondering if I'm missing something fundamental. (I couldn't find a lot of documentation online concerning static blocks in AS.)
I've been sorting through the XML docs and i've bumped my head into a bit of a question. So, to preface, I have been able to load the XML successfully, but I want to be able to use my own XML loader class to load the XML and then be able to reference it from the document class. Also, I'd like to be able to send a file path to the loader class when I call it.
The document class:

package rg.sites{

I have a class called Unit. When I use this class in a .fla file, I create it by saying:
var unit00:Unit = new Unit(...);
So then it creates a gfx representation of the screen for me. I would like to have a method like this:

So how do I get this to work? I know that delete this will not work when defined inside the class. How do I target the .fla's instance name when I don't know what it will be called?
ok, first of all, im not totally sure how to describe my problem so im going to recreate a simple example of what im trying to do...
my problem is that im not sure how to refer to a dynamic mc in a function...i know that sounds confusing but maybe this will help...
lets say i have a function like:
[Code]...
the problem with this is that the function looks for an mc titled "mcName"...and the function is hard coded...what i want to do....is to reuse this function with any movieClip on the timeline i want...so how do i refer to the mc in the function dynamically? i hope this makes sense?
ive also tried something like this
_root[mcName]_x = 123;
but this doesnt work either....ive seen something like this done before...using brackets to target an mc with a var...
ActionScript Code:
private var __milena:LoadVars;
private function Loadprom(prom:String):Void {

I am trying to make a button that when clicked on loads an external text file into a dynamic text box.
I can make it work when I use it specifically - but I can't make it work when I want to use it as part of a generic 'button function'.
Basically I have a .txt file "mycontent.txt" which is called using the Load Vars function inside a generic function (tab_grow) i created to managed the behavior of the 12 tabs that are the navigation for the movie. For now i'm just focusing on ONE of the tabs. Basically the tabs move when a user hovers over them and when they mouse off. When they click it should call the external text file. The section in the .txt i'm calling is called 'mega_data'.
This is what I have right now:
HTML Code:
function tab_grow(mov, file) {
mov.onRollOver = function() {
mov.onEnterFrame = function() {
[Code].....
BUT then I can't change which section of the .txt file I pull up for different tabs - which is the whole point of the function!!
I'm trying to load a local xml file:

I don't get this error when I embed the XML file directly with the EMBED metadata tag.

Lately I changed Flash CS3 for CS4. In older version classes written by me worked fine. However, in CS4 I have serious problem with them. Compiler states that part of my functions and vars are undefined, which is not true. I tried everything - changing name of class, functions, moving class file to different directory, removing package. I even counted { to check if they have pairs. I'm really out of options what can cause those errors.
Here are error given by compiler:
1120: Access of undefined property mnChangeMan.

Is it possible to delete a function?
I have a reusable function, on the first frame it works, but on the 2nd it doesn't load properly and duplicates itself because the other function is still running in the background.
I want to name a function, and in the next frame of the movieclip to delete it.[code]...

View 2 RepliesFor the example, there's a single FLA with a document class "main.as." In the public class main.as package, there is a public variable: "var example:String='example';." Inside of the FLA, there is one movie clip in the library and it is assigned a custom base class "sub.as." The movie clip is then placed on the first frame of the stage so its constructor is run at runtime and reads the value of example.
What is the proper way to get the value of "example" in the root document class? Using "root.example" in the sub.as class to target the document class returns an error and when I trace "root", I get "null." Main.example naturally throws an error because that's looking at the actual class and not the movie / stage its attached to.The round-about way I've done it before is to dynamically add the object in the library and pass in the root path when I create a new instance of it (example: submc:sub = new sub(this); ).Is there anyway to get back to the document class with a built-in method like root, etc?
I am trying to set the value of some static vars but I need to reference the class with a string rather than a proper constructor. In AS3 I can do this with:
var ref:Class = getDefinitionByName(classDefinitionAsString) as Class;
ref[varNameAsString] = newValue;
I can't find an equivelant approach that will work in AS2 though. I have tried:
var ref:Object = new [classDefinitionAsString];
ref[varNameAsString] = newValue;
This seems to just create an Object and as the vars that I am trying to access are static I don't really want to be using 'new' I just want to reference the vars.

I am a bit puzzled why this does not work when placed in my document class, but works when directly added a key frame in the Flash IDE.
ActionScript Code:
this['myVar1'] = new Object();
When within the document class I get this error when compiled,
ReferenceError: Error #1056: Cannot create property myVar1
I have tried the following but I still get an error.
ActionScript Code:
public static var root_Ref:Object;
root_Ref = root;
root_Ref['myVar1'] = new Object();

If I only instantiate a class once should I make its vars static? I understand how this is of benefit if I make multiple classes, clearly you use less memory as it creates a reference to the same place for each class. Are there any other benefits for creating static vars or functions ?
For example I have my class 'MainMenu' which I create once (might even be my document class). In it I create a
Code:
private var someHolderForStuff:Sprite = new Sprite();
Should I rather create
Code:
private static var someHolderForStuff:Sprite = new Sprite();
I cant access to var in parent movie from class in child.I have two swf's: parent.swf and child.swf. In parent.swf in frame 6 is:

stop();
var TestVar:String = "hello!";[code]....
I was trying use parent, parent.parent, parent.parent.parent etc. and any result - null object error.
The order of events are this. From the main stage I load a movie clip (movie clip 1), within that movie clip I have a button that loads another movie clip (movie clip 2) and also starts a timer that will automatically unload movie clip 2 . Within movie clip 2 I would like to create a button that stops the timer on movie clip 1 and starts it again.
I need to stop a function in movie clip 1 from movie clip 2 and then start that same function on movie clip 1 from movie clip 2.
This is the code I am using
This is the movie clip 1 code:

function moreTimerFun(moreTime) {
this.onEnterFrame = function() {
if ((getTimer()/1000)-moreTime>7) {
delete this.onEnterFrame;
