Quick 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 RepliesCan 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 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 am start developing small games (I have just finished reading a nice book from Rex van der Spuy) but I would like to use the best OO approach.Let's make a very simple example: suppose that i have a Player class which adds a listener to the stage waiting for keyboard events in order to move around the stage.I have also some enemies on the stage and the player must register a collision with them; what is the best approach in order to access the enemies on the stage and check for a collision with them on the ENTER_FRAME player's event? I have read a lot of solutions, but I am just starting coding and so I don't know which one is the best approach.
a) Access the document class directly with a getter (e.g. Main(root).allEnemies, supposing that every time an enemy is created it is added to the allEnemies array)?
b) A singleton class which has a reference to every instance in the stage?
c) I have read about using events, how?

View 1 RepliesIf i create a movieclip named player and in this class there is the proprety map(a string) and level(an int); I would like to know if there is a way of modifying these propreties without actionscript when i create an instance of that symbol.For exemple, like you would modify the height and the width of the object in flash, but modify this instance's proprieties instead.
View 1 RepliesI was wondering if there is a way to control the volume of a movieclip directly without using the sound class? Or is there a way to control the volume of the entire swf?
View 1 RepliesI 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 ?
I am creating objects for a game, they are all sprites. but I also want them to implement an interface. Is it possible to do both ?

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?
