ActionScript 3.0 :: Can't Instantiate A Custom Class
Sep 19, 2009
I keep getting this error: Incorrect number of arguments. Expected 0.Probably just something stupid... but I'm struggling...I have two classes (ribostrand.as and nucleo.as) in a folder called architect. The main FLA file is outside the folder.I'm trying instantiate the nucleo class with parameters, from the ribostrand class... but its not working.
var ribo:nucleo = new nucleo("A",50,50)
< code moved to the next thread and reformated >

I was chatting with my buddy about this, he is convinced you can do this and says he has done it, but I cannot get this to work.
I am wondering if it is even possible at all. I tried typing a var as a Class that is within the externally downloaded SWF and then making an instance but no can do.
some code
private static function onCompleteHandler(e:Event)
{
dashboardObject = e.target.content;
// registerClassAlias("Dashboard", ); doesnt work
[Code]....
So it seems you cannot make an instance of a class unless it is complied within the project SWF. Which if true is what I want it to do. I do not want people trying to make instances of my classes just from downloading the SWF file for what I am building here.

I have an abstract class which gives specific 'base' behavior to multiple sub classes. I want to instantiate a Singleton inside this abstract class. Is it good practice to:a) instantiate a class within an abstract classb) do this with a Singleton (I know these may be frowned upon)For clarity I will give an example, the method instantiating the Singleton is:
public function createErrorRepository(repositoryType:String):void {
this._errorFactory = ErrorFactory.getInstance();
this._errorRep = this._errorFactory.createErrorRepository(repositoryType);

To call a class we would type: var testClass = new TestClass();Can I store the class in an array, and somehow pull it when I want to call it the same way? I need to be able to call a new class like the example above, but from an array.

How can I instantiate another class object from a class instance? In the code below (which doesn't work) I'd like the function to return a new class instance based the passed argument's class. In other words, I want the function to return a new instance of MySprite without having to call new MySprite();.
var mySprite:Sprite = new MySprite();
var anotherSprite:Sprite = makeAnotherSprite(mySprite);
function makeAnotherSprite(instance:Sprite):Sprite {
return new getDefinitionByName(getQualifiedClassName(instance));
}

I'm trying to use a listbox to instantiate a class. "SEA30_05_215_Single_Classroom" is a class that is loaded in using another function just fine. When I attempt to use the function below I get an error that says "Instantiation attempted on a non-constructor."Any ideas how to either fix the error or do it a different way? It seems like it should be a fairly simple thing to instantiate a class using a list box..[code]

The following code works to instantiate a class from a listbox selection...
[Code]....
But when I try and load the same label and data from XML it does NOT work... Below is the for loop that I'm using to parse my XML and populate the listbox:
[Code]...
The setupID should be populating with a class that I can instantiate (just like when I hard-code it without using XML). Instead I get the error "Instantiation attempted on a non-constructor." I also received this error when I had quotes around the hard-coded version. So, I'm assuming that maybe the XML is being read as a string. But I haven't been able to find a way to cast it differently. I've been stuck on this for quite some time now.

Possible Duplicate: Where is the "proper" place to initialize class variables in AS3
Whether its better to instantiate class on it's variable declaration or within a constructor? For example, this:
protected var _errorHandler:ErrorHandler = new ErrorHandler();
or this:
protected var _errorHandler:ErrorHandler;
public function someClass() {
_errorHandler = new ErrorHandler();
}

I've got a string which, in run-time, contains the name of a class that I want to instantiate. I read suggestions to use
flash.utils.getDefinitionByName():
var myClass:Class = getDefinitionByName("package.className") as Class;
var myInstance:* = new myClass();
However, that gives me the following error:
[Fault] exception, information=ReferenceError: Error #1065: Variable className is not defined.

Can someone point me in the right direction on how to instantiate any class at runtime with any given number of arguments?
As an example and to be more precise, I included an example below. How could I write this example in one line of code - ok, maybe two : )

I have some classes stored in a swc which I would like to instantiate using data pulled in by xml - using a string to reference the classname.So where I would normally use
ActionScript Code:
var tagline:Sprite = new Tagline1();
I would now like to do something like
ActionScript Code:
var tagname:String = "Tagline1"; // really the string comes from XML
var tagline:Sprite = new [tagname]();
I have a vague idea this is possible using square brackets, but I don't seem to be able to find out anything about it.

Using org.as3commons.reflect I can look-up the class name, and instantiate a class at runtime.I also have (non-working) code which invokes a method. However, I really want to set a property value. I'm not sure if properties are realized as methods internally in Flex.I have a Metadata class which stores 3 pieces of information: name, value, and type (all are strings).I want to be able to loop through an Array of Metadata objects and set the corresponding properties on the instantiated class.[code]I realize that I have to declare a dummy variable of the type I was to instantiate, or use the -inculde compiler directive. An unfortunate drawback of Flex.Also, right now there's code to account for typecasting the value to it's specified type.

example:
var c : Class = Sprite;
//This can be random class such as movieclip/etc
var o = getDefintionByName(getQualifiedClassName(c));
this works, but in flash develop, it says that the variable 'o' has no type declaration
which basically means
var o : SOMETHING = getDefintionByName(getQualifiedClassName(c));
but how do i put that something there when i do not know what its coming because of random classes?

I'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?
MyCircle:
package {
//Imports
import flash.display.Shape;
//Class
public class MyCircle extends Shape {

I 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).

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function
var parameter1:customclass2;
customclass1(parameter1);
in customclass1 constructor:

This is my first time working with a class attached to a movieclip that is nested inside a class attached to a movie clip.I've tested all the properties and methods of PTListItem.as and they work properly but when I try to call them on the list item through PTListTop.as it returns undefined.The end goal is to dynamically load a checklist via a txt file.

I have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.

I couldn't work it out yet...
package components {
public class templateSelection extends VBox {
static public var tempSelectionBag:Dictionary;
[Code]....
I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:
Type was not found or was not a compile-time constant: Dictionary

If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.

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?

I keep getting an "undefined property" error when I try to call an external function from within the Doc class. I added the error message to the Doc Class below so you can see where it occurs.
If I take the code from the Tooltip.as below and place it on the FLA's main timeline I can get things working fine, but I would like to move all script to classes. The document class structure looks like this:
Drag_and_Drop.as
Code:
package {
import Tooltip;// Import custom class
public class Drag_and_Drop extends MovieClip {
[Code]....
I realize that I could just combine all the code in the Doc class to get it working, but it would be nice to separate out this particular code which has only one use.

the website I'm work on has the document class Main. Within this website I have a movieclip on the stage which I built a custom class for its functionality and I linked this movieclip to this class to make it work. There is no reference to this movieclip or class in Main.
Now, I need to communicate between these two classes. Can I do this? Can I dispatch an event from the custom class linked to the movieclip and have the document class listen for an event? How?
