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 ?
View 1 RepliesIs 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{
//
}
In ActionScript (AS3) how do I find all the classes that implement a particular interface?

View 3 RepliesBasically, what I want is to have a class that:
- extends Proxy.
- implements IEventDispatcher.
- has property "addEventListener" (it will also have this method).
or at least will trigger getProperty as a fallback when somebody tries to improperly access addEventListener...
Is there a way to generate an instance of a class that implements an interface based on the name of the class?
I am trying:
var ClassReference:Object = getDefinitionByName("movement.OuterSpaceMovement") as IMovement;
var m:IMovement = new ClassReference as IMovement;
trace("startup..." + m);
-But I am getting an error message ReferenceError: Error #1065 (OuterSpaceMovement) not defined.
I have several classes that implement the same interface (IMovement) but I need to be able to generate new instances of these classes and then pass these instances as a datatype (IMovement datatype) to other classes...
So then I tried:
var ClassReference:Class = getDefinitionByName("OuterSpaceMovement") as Class;
var m:IMovement = new ClassReference() as IMovement;
and this doesn't seem to work...but the following
var m:IMovement = new OuterSpaceMovement();
I'm trying to load a RSL library into a flash animation developed with Flash CS5 IDE, that extends a custom class and implements an interface. I have reduced the problem to the simplest setup and find that I can have my main class extend another class or implement an interface, but not do both at the same time if I want to load an RSL.I have a very simple class to extend:
import flash.display.Sprite;
public class MySprite extends Sprite
{[ code]...........
but if I want both I get the VerifyError: Error #1014 with MySprite not found and ReferenceError: Error #1065.
i am working on a project where i have some common code which i import in different movie clips and different files the code is in actionscript 2 in an external .as file. this is not a class its just a bucnh of functions and temporary variables.Problem is when i use the check syntax button or auto format button i get the following error."ActionScript 2.0 class scripts may only define class or interface constructs."this used to work fine in flash 8 but it always gives this error since i started using flash 9.the code works fine too. its just that my auto format button and the check syntax doesn't work.

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:

How do I implement a listener within a class? I am instantiating other objects within side of another class. A sorta parent and child thing.

I'm trying to publish a swf with Flash CS3.
I have one .fla file and two .as files. I think my problem is I don't know how to set the path for the action scripts. All three files are in the same directory
The files:
dtd.fla
TransformItem.as
TransformManager.as
The error: The class or interface 'gs.TransformManager' could not be loaded.
dtd.fla code appears to have an appropriate import: import gs.TransformManager; var manager_obj = new TransformManager([], onTransformEvent, true, false, false, false, false, true, true);
TransformManager.as code appears to have an appropriate import: import gs.TransformItem;
I'm doing a simple link code. I've tried many diferrent ways to do this but this error keeps comming up saying The class or interface could not be loaded...
home_btn.addEventListener(MouseEvent.CLICK, gotoURL);
function gotoURL(event:MouseEvent):Void{
navigateToURL(new URLRequest("my site"));}
This is the most recent method I've tried in doing this. I've tried changing the publishing settings of the document to and from Action Script 3.0- using an import command. But thats too complicated.

I have created the following classes for sharing images. They implement an interface, but I need a way of switching between them with user interaction. I've done it the following way:As you can see, service 1 and service 2 implement iSharingServices, and inherit from PolimorphSharing.PolimorphSharing is simply and an abstract class that implements the methods I want public from Service 1 and Service 2. Those methods will then be overridden on the Service 1 and Service 2. Because I need a way to switch the service in runtime, I've created a gateway class that inherits from PolimorphSharing. I can then call it the following way:
private var sharingService:PolimorphSharing = new SharingServicesGW('svc1').createService();
This all works flawlessly, and I can now switch between services with no problem whatsoever. However, I feel there's something wrong about it, so I would like to ask you guys for some advice on how to better implement this.
UPDATE:
Just adding some more insight to this. Basically the idea here is for my client to be able to upload images with various different public sharing services such as imageshack, imgur etc. I want my client to be able to select the service in which the image is to be published to (hence the "switching between them with user interaction" bit of the question.
The method that does the uploading bit, is requestShareImage(), processResults() simply turns whatever gets returned to a unique format, so my client can read off it always the same way. getObject() is my accessor, and onIOError will handle exceptions with any of the public API's

I am getting an error with RegExp class at my flash document. I am using an Action Script 2.0 at my document. Is RegExp class is not supported in AS1/AS2 ?
My code is as follows
function validateEmailAddress(emailString:String):Boolean {
var myRegEx:RegExp = /(w|[_.-])+@((w|-)+.)+w{2,4}+/;
var myResult:Object = myRegEx.exec(emailString);
if(myResult == null) {return false;}return true;
} if(validateEmailAddress(email) == false) {
contacterror = "Error ! Please Enter Valid Email Address";}
If RegExp not supported in ActionScript 2.0 then how to validate email address at ActionScript 2.0 ?

whats the purpose of having to have an extra class such as abstract class in Flash where the methods has no implementation,but the subclasses declare those implementations.The advantage of having the methods declared in subclass than the superclass is that it would not affect the other subclasses when there are certain changes.That makes me wonder, isn't it better not to extend(inherit) empty methods but directly create a class as its own? unless there is something that the child could use from parent.Anyone could give me examples of how applicable using abstract classes/interfaces?

View 1 RepliesI'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:

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.
