ActionScript 3.0 :: Using A Variable As A Class Name?
May 8, 2009
Having just made the jump from Actionscript 2 to 3, I'm having problems.Is it possible (I hope so) to use a variable when creating a class?I have a movieclip 'exclam' in the Library, and want to programatically add it to the scene: I can use the code:var asset:exclam = new exclam();to do this. However, if I have a variable 'textvar' containing "exclam", I'd like to use code like:var asset:textvar = new textvar();Of course, it doesn't work, since it thinks 'textvar' is the name of the movieclip I'm trying to use. Hopefully it's just a matter of syntax.

I realize this is kind of an odd issue, but I am wondering if there's any way to get Flash to allow me to access a class's static functions using a class variable that points to the class. Example:I create a class called FooClass that has a static function named fooI then create a variable of type Class that points to it
Code:
var class:Class = Class(getDefinitionByName("FooClass"));
However, when I try to call foo() using the variable, it errors saying the function

I'm trying to create a class which will create a tween for several different instances of an object. I am creating the instances in the Document Class. The trick is, I would like to specify how long each tween will take.
Here's what I have so far:
DOCUMENT CLASS
ActionScript Code:
package {
import flash.display.MovieClip;
import mcCloud;
[Code].....
As you can see, I have a variable "myTime" which syncs the timer and the tween. This causes to tween to repeat and the clouds to continually scroll across the stage. How can I determine the var myTime at the time I create each instance of the Movie Clip mcCloud?

When I declare a class variable
private var myVar:MyClass = new MyClass();
It creates a new instance of that class that will trace as [Object MyClass].
However, as soon as I assign it to something
myVar = thisOtherVar;
It will now trace as [Object thisOtherVar].
I need to get it back to where it's just an "empty" blank class instance, if that makes any sense at all.

I've only been programming in as3 for a couple months, and so far I've written several compositional classes that take MovieClips as inputs to handle behaviors and interactions in a simple game I'm creating. One problem I keep coming upon is that I'd love to access the custom variables I define within one class from another class. In the game I'm creating, Main.as is my document class, from which I invoke a class called 'Level1.as' which invokes all the other classes I've written.Below I've pasted my class 'DieLikeThePhishes'. For example, I would love to know the syntax for accessing the boolean variable 'phish1BeenHit' (line 31) from another class. I've tried the dot syntax you would use to access a MovieClip inside another MovieClip and it doesn't seem to be working for me.[code]

How do I listen from the main class to a sub class for a variable change?

public class DataBase extends MovieClip {

This is what I have so far for the sub class but I can't seem to figure out how to listen to this variable change from Main() or even if I am dispatching the event properly.

I have two document classes. One is Main.as the other is Step2.as. I want to declare a public variable in Main.as then need to give it a value from Step2.as. That value will later be used in my next Document class Step3.as How would I write the code that gives the value in my Step2.as and then how would I write the code that retrieves the value in my Step3.as?
Note I can't import my Step2/ or Step3 document class into my Main.as.

ActionScript Code:
private function xmlLoaded(e:Event):void{
xml = new XML(e.target.data);
for (var i:int = 0; i < xml.item.length(); i++) {
var btn:Button = new Button(xml.item[i].label, xml.item[i].@id, xml.@colorOver, xml.@colorOut);
btn.y = Math.floor(i * btn.height);
[Code] .....
Simple, inside my Button class I gave a value to "id" how can i retrieve it from the event? Tried lots of stuff, just don't know how:
trace(e.target.id);
Something like that.

I have just created a class 'ClassA' that loads an XML file.Within that class I have a public function that navigates through the XML and populates arrays with the XML content.
I am now creating another class, which will be called 'ClassB' which I plan to extend 'ClassA'.
>From 'ClassB' I would like to reference the array variable (which is not in the constructor) to re-use in the 'ClassB' class. I have tried tons of different ways all of which I get undefined.

i'm having an issue fitting setInterval() methods into an AS2 class--basically, since setInterval works by calling a function at a set interval, and it returns an object reference, like this:
Code:
public function loadSplash():Void {
var id=setInterval(loadSplashMC,1000);
var sM:Object=new Object();
Mouse.addListener(sM);
[code]....
the problem is that i can't set a class variable to id--i tried defining it as a generic object, like this:
public var id:Object;
but it didn't work...i'm not used to working with setInterval, so maybe i'm just not using it right--perhaps i should put it all into one function?

Any way that I could get a variable definition straight from a class (or some sort) without having to create an object and read it from the object. Basically I need to know a whether an object will have a specific true or a false variable definition but I don't need to create the object right away for anything else. It seems a bit of extra processing to create an object I may not use for sometime but just needed to know a true/false early on. I can give it the name of the class just hoping to bypass the object creation and hope garbage deletion will take care of it.

How to access a local variable from another class? I have this powerup class that changes the speed value of the enemy in enemy class(it's a game). For instance, if player hits the powerup it changes the local variable 'speed's value inside enemy class.

I am calling a function in one class from another (primary) class. That works with a straight function call.However, the function I am calling loads an XML file and, upon load completion, calls a handler function.My problem is that all data in the handler function disappears when the function terminates so I cannot access the result from the primary class.

I've created 2 public variables in my Document Class...
public var _wall1:Wall=new Wall();public var _wall2:Wall=new Wall();I've then added them to the stage and given them relevant instance names...
stage.addChild(_wall1);_wall1.x=32; _wall1.y=510;_wall1.name = "wall1";I then want to use these variables in another Class (Ball.as). They need to be accessed in a function within the Ball Class constructor.
function bubble(event:Event):void{if(this.hitTestObject(_wall1)){ this.x += 1;}else if(this.hitTestObject(_wall2)) { this.x -= 1;}However, the following Error message keeps appearing...
1120: Access of undefined property _wall1.1120: Access of undefined property _wall2.Any pointers? Do I need to import something into the Ball Class to point to the _wall# public variables in the Document Class?

I want to use height in [SWF height=200] for class variable.
I tried the following code but it causes compile error.

If I use the number, 200 instead of const SWF_HEIGHT, the compile error doesn't happen. But I don't want to write the same number on 2 places.
Is there way to avoid writing the same number on 2 places?

trying to get a variable set so that I can use it in another class.I am trying to set the class variable animate. My "intended" goal is that I am trying to load in an external SWF file that is a pulley In this external SWF file I have a function that stops the animation called "stopAnimation()". I want to be able to access this stopAnimation function in a couple of class files. So I pass this object to those classes and then I should be able to access the stopAnimation() function from where ever but I cannot seem to get the contentloader info into a class variable in order to call it from other objects.
Here is the code

package com.ahicks.assets{
