Is this possible ? If yes how ?Otherwise what's the alternatives ?
By dynamically I mean using

Is it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip {
public function CustomRectangle(width:int, height:int) {
this.width = width;
this.height = height;
}
}
I'm passing a DisplayObject to a command that will instantiate it. Something like this:
// ViewClass is passed into this method typed as a Class
var view : DisplayObject = new ViewClass() as DisplayObject;
Is there a way to pass arguments to ViewClass() without knowing it's type? I'm assuming the list of parameters passed to any object's constructor is an array, but I'm not certain how to proceed.
I know I can do something like this:
// Assume arguments, an Array of arguments, has also been passed in
var view : DisplayObject = new ViewClass(arguments[0], arguments[1], arguments[2], arguments[3], arguments[4]) as DisplayObject;
But clearly I'd like something more dynamic, like to be able to just pass the arguments Array directly. I suppose all of this, however, goes against any type safe checking
For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)

I have an object that has all the elements I would want to pass arguments: var args:Object = { 'dog', 11, myArray }; and I want to be able to pass the contents of args to doSomething without making any changes to doSomething (assume it's someone else's function) and I'd like to do it in a way that doesn't assume I will know anything about the contents of args.
I want to pass through configuration arguments to a class. These are all the optional vars that go into configuring the class - and should be able to run in any order.
at the moment i just pass through the optional vars the regular way. Supposing the constuctor was like the following:
private var _reqVar:String;
private var _optVar1:String;
private var _optVar2:String;
[Code].....
assigning the argument to the var of the same key (i know in php to reference a variable name from a key you can use $$key = $value, is there an equivalent in as3?) display an error (using the 'throw' method) for variable names not supported by the class
I have the Class and the parameters of its contructor as an object. What I need to do is a function that returns an instance of this class, passing this parameters to the constructor.
This is the code:
Some random and unmodifiable class:
public Foo {
public function Foo(a:int, b:String) {
// constructor
}
}
And some function (in some another class):
function bar(params:Object):* {
var baz:Foo = new Foo(params.a, params.b);
return baz;
}
What I need to do is make this function generic, without pass params as parameter to Foo constructor because I can't modify it. Something like:
function bar2(clazz:Class, params:Object):* {
var baz:* = new clazz(/*some magic way to transform params in comma separated parameters*/);
return baz;
}
I have a class (ImageLoader) that extends Sprite container and loads an external image to its instance. When i instantiate an object of this class from another (Main) class i want to have the dimensions (width, height) of the loaded image being known to this (Main) class. It seems that is difficult for me as the dimensions are known after the image compete loaded. But i don't know how to pass this information from completeHandler event handler to the Main class.

I am really pulling my hair out with this one. Flash game, container swf loads a img using the loader class. The image is the map which will be used on the levels. The problem im having is that I originaly had each level load the map image, convert to a bitmap, and us it to create x and y's for colision detection.
the problem was that the game was loading and sometimes the map image hadent loaded. It also ment that each level was loading the same image and if the above happened on the 3rd, 4th level it was very annoying. So I need a way to load the image in the parent, but have it available to the child, however it must be available as at bitmap to work.

Is it posible to have predefined arguments in a constructor so if the user doesn't enter one it takes the default value? I tried doing it this way:
[Code]...
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap;
var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
I have a bunch of sprites in my library which all behave in the same way.
now i want to put the behavior and all the common methods into one BaseClass [code]...
I'm having a weird behaviour with some some classes that I'm making. It seems that the Boolean values from arguments get changed on the way. I have two classes. On is called Carousel and the other Activity. The Carousel main task is to instantiate several Activity objects and place them in a way that resembles a carousel. This part is done, but there's a problem passing arguments from Carousel to Activity. Some data to instantiate the Activity come from an XML file. The XML resembles something like this:

I'm making a game in action script 3. In it, I have an actor class from which player and enemy classes will be derived. I'm doing this so that unless I need to provide specific AI or fancy behavior (such as for bosses), I can just make a new clip in the library for each enemy without making an actionscript file.
However, I've run into a problem.
Whenever I try to pass arguments to the construction of an enemy (make it spawn with more health), I get error 1136 (Incorrect number of arguments.)
This is because the constructor created automatically at runtime doesn't have the same arguments as it's parent class. Is there any way to get around this without making a class file where I copy and paste the parent constructor function for each of my hundreds of enemies?
I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.

I like finding out about tricky new ways to do things. Let's say you've got a class with a property that gets set to the value of an argument in the constructor, like so:[code]That's not exactly a hassle. But imagine you've got... I don't know, five properties. Ten properties, maybe. Rather then writing out each individual assignment, line by line, isn't there a way to loop through the constructor's arguments and set the value of each corresponding property on the new instance accordingly? I don't think that the ...rest or arguments objects will work, since they only keep an enumerated list of the arguments, not the argument names - I'm thinking something like this would be better:[code]
