I don't know the term for this problem, but essentially I want to create an object in Flex/AS3 based on the name of its class.
See my code explaination below:
private var obj1:String = "dog";
private var obj2:String = "cat";
this.createChildByClassName (obj1);
Basically... I want to create something based on the type - which is stored in a string.
I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.

I've been playing around with custom classes. My objective was to create a custom class (Testing) that would create a box when an instance of the class is created. I've tried three different approaches, however only (3) seems to be showing up. I'm just curious why (1) or (2) doesn't work?
Also is there a better approach than (3)? Since at the moment it's been created on _root. I hope the box can only be accessible through the instance. Since I'd like to incorporate the whole idea of public, private, encapsulation, etc.

i) Create a symbol called SimpleSquare. This should consist of a simple red square graphic
ii) Create a class file to define a class called SimpleSquare. This should be linked to the SimpleSquare symbol. SimpleSquare ashould have the following functionality: When the instance is placed on the Stage, it should start to disappear by decreasing its alpha at 0.01 in every frame (hint: alpha)
create a class that delivers the a text format to a requesting class. Unfortunately, even though when I trace the return it comes back with [object TextFormat], I do not see the results of the formatting. Heres [part of the clas trying to use the txtformatting class:
ActionScript Code:
private function buildTF(msg:String = null):void {
with (_tfield) {
alpha = 1;

I have been practicing and trying to understand how classes work and I was wondering if it is possible to create a class that can be reused by declearing the class only once in my fla file. Rightnow I create an instance of the class than I asign it to a MovieClip the problem is that I can only use it once and if I want to use it again I have to create another instance of the same class, something like this.

I have a problem with classes. What I am trying to do is this: I create a main class and then i import another class into it.then I create an instance of the new class and add it to the stage.the problem occurs when im trying to use the new classes methods.
import classes.NewClass;
var test:NewClass = new NewClass();
addChild(test);[code].....
How do I create a class that extends the String class?
Lets say I've created an 'exString' class that extends String.
In my project file I do the following
Code:
var test:exString = new exString();
test = "Hello World";
text.someExStringFunction();
I get a type mismatch in my "Hello World" assignment because Flash sees it as a String and not as an exString.
This is what i'm trying to do :
I have 1 class that extends movieclip, let's call it Class0. I have 1 class that extends movieclip, let's call it Class1.
I create an instance of Class0 on stage like : var myClip0:Class0 = new Class0(this, "Class1");
The class Class0 when initializing, will create a new movieclip (myClip1) and add it as child, as an instance of Class1, like myClip0.myClip1. But it's when i create that clip, i want to tell it, it's an instance of Class1, like :
private var myClip1:Class1 = new Class1(this);
Where Class1 could be any class.
How do i pass Class1 to Class0 so it can create it dynamically?? Do i have to use the apply function??
inside Class0, i have a function that does :
Code:
if(subClass){
initSubclass(subClass);
}

I want to create a movieclip class that subclasses another movieclip class and inherits all its properties (rather than having to rely on the include statement). In my project I'm using:An abstract parent class that extends a movieClip: "infantryDroid".[code]However everytime I try this, flash acts as though nothing was imported from the parent movieclip class.If I was to try the above code I would get the message that _root and speed (which were defined in the parent class) "are undefined".
View 6 RepliesI am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

View 3 RepliesI recently learned how to use gravity so I made a bouncing balls program but I have an issue with the interaction between the frame timeline code and the class.The problem is that when I create instances with a timer, I declare the variable inside the timer function. And I want to add a blackhole sort of thing when I click down on the stage but I cannot access the object from the blackhole function since it's declared inside the timer.

View 3 RepliesI can't figure out how to create a reference to a class so I don't have to keep typing the class.staticvar.item
So usually I have this: DocClass.build_class.firstFunction();
I would rather in my sub class just be able to say; private var build_class:Class = Class(getDefinitionByName("DocClass.build_class"));
so throughout the sub class I only have to type the reference, build_class...
What am I doing wrong?
In action script 3 I can just extend the event class and create my own Event Class.how can I achieve the same results using action script 2?

View 9 RepliesI have a class that I want to be able to create a movieclip from and then add it to the stage when it's instantiated. The constructor takes two arguments but nothing special.I had one solution that added the movie clip, but then I couldn't modify the _x and _y values of it directly from the .fla. What would be the best way to do this? Should my class extend MovieClip or no?the formatting is something like:
Code:
class Foo extends MovieClip{

View 3 RepliesI am attempting create a class for the first time. My idea with this class is that you will be able to pick a colour scheme "warm", "cold" and all the code will be there for you when you need it. So with warm, I have it randomly selecting different warm colours.
I have the code working the way it should in an action script 3 file, but when I transfered it into a class I have gotten many problems which I probably half solved. If someone could take a look at my work and let me know what I might be missing that would be helpful.
Right now when I go to preview it it just shows a black box. I'm assuming its something to do with my "beginFill();" which just has a "1" in it right now becuase I can't seem to write anything correctly!!
Here is what I have in my class;
package com.avis340.randomColor
{
import com.avis340.math.MoreMath;

View 1 RepliesI have written a Class for skinning the UI. The Class works by taking a movie clip name from the stage passed to it and create the skin for it.So I create an Object from the class such as this:
Code:
var CBox:UI = new UI();
Now what I wanted to do is reference a movie clip from the stage to this CBox variable, so when a call the Class methods it will know which movie clip to work on! Since currently I have to do this:
Code:
CBox.Skinning(content_mc, "content", 100, 200);
or
CBox.Over(content_mc);
As you can see Im passing the movie clip, content_mc, everytime. I just want to avoid this by creating a reference.
In class A I write
Actionscript Code:
[...]public class extends MovieClip public function ():void { public static var menuContainer:MovieClip; menuContainer = new
