I made a class in AS3 for representing complex numbers. It does not inherit anything. How can I enable casting from e.g. Numbers? I.e. I want this:
5 as Complex
to be the same as this:
new Complex(5);
is there a magic cast() function I can put in my class?
I have tree instance calling an iconFunction "getIconFromItem".
<mx:Tree dataProvider="{collection}" iconFunction="getIconFromItem" />
The getIconFromItem function is returning null even though the bitmap is not null.
public function getIconFromItem(item:Object):Class {
var result:Class = item.icon as Class ;
return result ;
}
Setting a break point on the return result line reveals that item.icon is a bitmap and result is null.
how to successfully cast a bitmap as class so that the bitmap is returned as an icon?
I am using Flex 4 and for whatever reason I cannot get the following code to work which happens inside of a ListEvent handler for a dataGrid:
_tempRule = DataGrid(event.currentTarget).selectedItem as Rule;
Rule is a custom class, and the above code always returns null. The dataprovider for the datagrid is an ArrayCollection. If I try to wrap the above code to make it like the following:
DataGrid(event.currentTarget).selectedItem as Rule
I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert Object@e15a971 to com.mycompany.arcc.business.Rule
Now I know I have done this before with native Flex classes like Button, etc, but it my case it will not work. Here is the Rule class:
package com.mycompaany.arcc.business {
import flash.utils.describeType;
import mx.collections.ArrayCollection;

I have a mediator that I've registered for a navigation page:
facade.registerMediator(new NavPageMediator(viewComponent));
I'm trying to retrieve that mediator on another page like so:
var navPageMediator:NavPageMediator = facade.retrieveMediator(NavPageMediator.NAME) as NavPageMediator;
However, that statement returns null. If I try to cast it using the NavPageMediator(facade.retrieveMediator(NavPageMediator.NAME)) syntax instead, I get a TypeError: Error #1034: Type Coercion failed: cannot convert com.website.mvc.view.page::NavPageMediator@237560a1 to com.website.mvc.view.page.NavPageMediator.`
I can't, for the life of me, understand why NavPageMediator@237560a1 would be unable to convert to NavPageMediator, nor what happened in between registering the mediator and retrieving it that caused this. Especially since trace(new NavPageMediator() as NavPageMediator); returns [object NavPageMediator].
Incidentally, and this may be part of my problem, I don't understand what the @hash at the end of the object is (@237560a1). Is it simply an internal identifier for that class instance?
Edit:Left a bit of important info: The SWF in which I instantiate and register the mediator is separate from the SWF in which I try to retrieve it.
Can I implement more than one interface to the same class?One option is to make interface A extend interface B and than have my class inplementing interface A. Is there any other way that I can implement two or more interfaces directly to the same class?
View 3 RepliesQuick question. Does a class have to implement a interface directly to be accepted, or can it be a child of a parent class that implements it. so If I pass a child object into a method that only accepts IOBJECT, but the child class parent implements IOBJECT. will child object be accepted ?

Is there any way of extending a class which is extending the movieClip class? Or generally a way to add extra methods to an allready existing class without having to add them in the actual class declaration. I was thinking of using Interfaces but how can I implement an Interface to a class which is extending a movieclip?
Code:
import interfaceName
class className implements interfaceName{
//stuff
}
But where do I put the code which extends the MovieClip?
Code:
class className extends MovieClip{
//
}
Actually, I already know the answer. The main reason I'm posting it here is for Google searchers, and if I copy and paste the post into my blog, my ActionScript code gets formatted all pretty, when all I have to do is add "as" tags here.

I'm having some trouble implementing a "virtual" camera for use in game development with Flash CS4 ActionScript 3.0.Basically, what I'm trying to accomplish is to have a camera that moves about the main stage so that my character can traverse the level which is much larger in size than the stage itself.I've been using Sham Bhangal's virtual camera script, and when I implemented it by sticking the code into the first frame of a movie clip, it worked great!
From there, I moved the code into a document class that i could instantiate and then drop onto the stage as a child.Finally, I wanted to have a main "builder" document class that would be added to the main stage as a child, and within THIS class I wanted an instance of the virtual camera. This is where I hit some obstacles.how to properly instantiate the virtual camera within the builder class which is then added to the main stage. I have a Stage reference that is being passed to the main builder, but I don't know where to go from here. To what do I add the virtual camera to as a child? To the Stage reference in the main builder class? To the main builder class itself?The main issue is that when I export my movie with the virtual camera added as a child to the Stage reference within the main builder class, it complains that I'm not allowed to access certain values.
Code: Error: Error #2071: The Stage class does not implement this property or method.
at Error$/throwError()
at flash.display::Stage/set x()
This happens when I try to access parent.x from within the virtual camera class. I assume this fails because "parent" from this perspective is the main builder class, but using the Stage reference produces this same error.I am, of course, willing to provide more detail if something I've written is confusing, and I will gladly provide a detailed fix for those seeking to use a similar solution in the future.
To start - its best to say im new to Flex / OOP in general. I have been trying to add a custom class based on StrokedElement in order to implement a simple grid (not like the existing Flex Grids - this would just be for display - not holding elements etc...)
My current class looks like this:
package ui.helpers {
import flash.display.Graphics;
import spark.primitives.supportClasses.StrokedElement;
public class SGrid extends StrokedElement {
public function SGrid() {

So I've been trying to move the stage's X and Y position and keep on getting this error:
Code:
Error: Error #2071: The Stage class does not implement this property or method.

I am using a document class, here it is:
Code:

import flash.display.MovieClip;

import flash.events.MouseEvent;

As for why I'm trying to move the stage, I have a movieclip which moves according to keyboard input and i want the stage/Background to always center on him.
I have a java class which has been deployed as WAR web application in a BlazeDS/Spring server sitting on JBOSS. Apart from the Flex application which will access the WAR file, I also need to start some server side process's which will initiate BlazeDS "pushes" to the Flex client via AMF messaging.
What is the best way to implement this server side process? - Should it just be a class with a main() method in the WAR file which gets called from the command line? Can this be done - not sure you can run a class in a WAR file from command line? - Should it just be a class with a main() method in a JAR file which gets called from the command line? Not sure what the standard practise here is. The key is that the process needs to be started on the BlazeDS server to push data out (not on the Flex client).
I've got a custom mxml component that currently implements IResponder. Passing this IResponder to a function works fine using this. This, however, includes implementing the public methods result and fault, so I'm asking if it isn't possible to pass a new IResponder to a function, somehow like this: object.function(someProperty:String, new IResponder());

View 2 RepliesI have a base class called Room and a subclass called Attic, and another called Basement.
I have a controller class that has an attribute called CurrentLocation which is type Room. The idea is I want to be able to put Attic or Basement in that property and get it back, then cast that to whatever type it is.
So if on the controller the content is of type Attic, I'm trying to figure out how to explicitly cast it. I thought I knew but its not working... Here's what I thought it would be, borrowing from Java:
var myAttic:Attic = (Attic) Controller.CurrentLocation;
This gives me a syntax error:
1086: Syntax error: expecting semicolon before instance.
So how do you cast implicitly? Or can you? I could swear I've done this before as as3.

I am calling on different types classes from within a loop. The objects can be of different types so therefore I am using the getDefinitionByName method. here is a piece of my code:
for(var y = 0; y < mapH; y++)
{
brickHolder[y] = new Array();
[Code]....
But I got an error when I tried to call on methods. The interface is blank; doesn't have any methods in it. I am not sure if that makes a difference. But the parent class inherits it and the subclasses inherit the parent class. Can I instead use the parent class?
var brick:ParentBrick2 = ParentBrick2(new classRef());
In a nutshell, what can I do to loosely cast these objects so I am able to use any subclass methods that get called?

Okay so quite an ambiguous title but what I'm trying to do is cast a shadow off shapes from a light source. Simple enough and I have it working but I just can't work out how to fix the problem of when the light source is at a certain angle to the shape I'm casting a shadow from.I know it's the whole 180 to -180 thing, but I just can't think of a work around.I've attached the swf and fla so you can see for yourself.Basically the code works by chucking points of the shape in an array and then arranging the array by the angle of each point from the light source. No big deal. From there it just takes the first and last point in the array and draws a shadow from there. Sketchy for the time being I know, but I just don't understand why it's doing what it is.
View 0 RepliesLet's say I have 3 items in the same package:Shouter interface - requires implementers to implement the shout() functionShell class - implements Shouter...this Shell.swf is to be loaded remotely from:ShellLoader class - loads Shell from a remote server, casts it as a Shouter and invokes its shout() function...uses allowDomain in order to cross-domain script.Now let's say ShellLoader.swf lives on and Shell.swf lives on ....I've got a cross-domain policy on Using LoaderContext's ApplicationDomain and SecurityDomain, I'm able to load and cast the Shell object as a Shouter and invoke the shout() function. Everything ok here.
Now let's say ShellLoader is run locally and is localTrusted. Shell.swf still lives on I'm now unable to use SecurityDomain property of LoaderContext within ShellLoader because it is now run locally. Shell.swf now exists in a different ApplicationDomain as my ShellLoader and I get the error "Type Coercion failed" when I try to cast the loader content as a Shouter.Is there anyway to resolve this issue? I believe it will require Shell.swf to be loaded in the same ApplicationDomain as ShellLoader but I don't know any way to do this when ShellLoader is run locally. Perhaps this is prevented in the Flash player on purpose?
