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.
View 3 RepliesIs it possible to instantiate MovieClips that exist in the library (that have been exported for actionscript) with a for loop using an array that holds their link name?
var fruit:Array = new Array("apple", "banana", "blackberries");
for (var i:int = 0; i < fruit.length; i++)
{
var aFruit[i] : fruit[i] = new fruit[i];

Incorrect number of arguments. Expected no more than 0.hen I try to:ar countries:Country = new Country(10);ormally this would work in Java or C++, so I'm not sure what's up!?Here is my custom class.
package {
public class Country {
var cName:String = "noName";

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)

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);

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]
View 4 RepliesThe 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.

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.
View 1 Repliesexample:
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'm trying to call a function in one class from another class and I'm using an array in the function of the class that I am calling from the other class. The array is declared and instantiated in the one class but when the other class calls the function with the array in it I get an error #1010: A term is undefined and has no properties. because the class that is calling the function that contains the array doesn't know that it is already declared. Anyway here is the code.
//CLASS THAT CALLS THE FUNCTION OF THE OTHER CLASS WITH THE ARRAY:
public class SpaceWolf extends MovieClip
{
private var _playerMissiles:PlayerMissiles;

Migrating to AS3 is being harder than I supposed, because the way things are referenced. I have a stay movie clip instantiated from library like this:
Code:
var mcMyMain:MovieClip = new mcMain();
addChild(mcMyMain);
var mcMyChild:MovieClip = new mcChild();
mcMyMain.addChild(mcMyChild);
Within mcMyChild I have a timeline with some animation, and, at the end of this timeline I want to instantiate another movieclip in mcMyMain (that is in stage) like this:
Code:
stop();
var mcMyTest:MovieClip = new mcTest();
stage.mcMyMain.addChild(mcMyTest);

I would like to know if its possible, to use a string in order to create a UI element.I think many people have this kind of problem, they want an easy setup in flash to generate a dynamic UI, through code.It should look like this (pseudo code):

addToStage("TextInput","name");
private function addToStage ( o : Object, str : String ) : void {

View 1 RepliesI have been trying to get buttons to work when linking back from an html page to a frame in a .swf movie for a couple weeks now, I have searched exhaustively to no avail. I am out of resources, I have searched every variation of the issue in multiple places and just cannot find an answer.
In a nut shell, when the "home" page (.swf in an html container page published with html anchors) runs first time all is well, buttons function goes to certain frames no prob. But once the links go out to another html page, and then back to the frame in the .swf, all links properly back to correct frames, but then the buttons don't function anymore. The closest I have gotten to solving this is it was mentioned that the mouse event code is not instantiating for some reason that I cannot understand.
The code IS on all the fames that are in question, but just will not work after linkback.

As simple a problem as the title says. I must be doing something really stupid. I've got a large section of a site, built a month ago runs fine. Went to make some changes. Now when I compile the video instantiantion fails. I've gone back to basics to test this problem out and it persists.So, here's my document class:package sections{import flash.display.MovieClip;import flash.media.Video;public class LocketVideo extends MovieClip{private var _vid:Video = new Video(200, 200);public function LocketVideo() {trace("hi there");}}}When I compile the swf I get the following error:/Projects/[omitted]/Src/sections LocketVideo.as, Line 9 1137: Incorrect number of arguments. Expected no more than 0.( line 9 is the _vid line )Now, if I pull out the parameters of the video object it works fine... well compiles fine. A video object without a size isn't much use. Note that if I don't set parameters... all other calls to the object fail.My first thought was that my default Flash classes got corrupted. Nope. Ran this compile on two other computers, same issue. Also thought maybe I had the fla set to the wrong .

View 1 RepliesHow can I instantiate a TabViewNavigator from actionscript for the playbook? Currently, I add the necessary spark frameworks and have this piece of code in the Main of my actionscript project:

public class Main extends Sprite {
private var waitDialog:BaseDialog = new BaseDialog ();
public function Main() {
super ();

When the button is clicked, the button disappears as you would expect but the tab navigator is not added/does not appear. I tried without removing the Main class but that does not work either. What do I need to do to set up a tab interface. I can get similar code working through Flex and MXML but not in actionscript.

when you have some kind of module for a website for example, what is a better way to code you application?If i load external swf, then i obviously need to compile it before from fla, but i can have some symbols in the library directly in that fla file.if i make an instance of a class, then i dont need swf file but then i need to take care of library stuff (if any) differently...
