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 ? If not, how can i have an object have the capabilities of a sprite and also have it implement an interface. I am wanting to create another class that checks all my objects to see what datatype they are and evaluate them accordingly
View 1 RepliesI can't quite wrap my head around the differences. In what situations would I choose one over another?Specifically, I'm creating a sort of View component (in a very hack-y sort of way, I'm sure) that can redraw the interface with the same visual components (some of which change slightly depending on the mode) in 3 different modes: Normal, Small, or Fullscreen. The trick here is that both the Normal and Small modes can *also* go fullscreen as well, though you'll never be able to switch between Normal and Small in the same session (it's determined up-front).
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{
//
}
i seem to have trouble finding on the internet what happends when one interface extends another interface.

If you run these, you'll notice that the MXML-component can't hear the event. The question is simple, is there some way of getting the Event-metadata tag to work WITHOUT extending EventDispatcher? I would like to keep this class independent and use object composition as much as possible. And no, I don't want to use ActionScript addEventListener in the MXML-file. It doesn't tell the developer anything like good old Event metadata tag, and besides, that is not the point of this example. :)

View 6 RepliesIs 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

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.
View 5 RepliesI want to add a property to the MovieClip class. I just have a bunch of MovieClips that are placed on the stage by reading an XML file and creating lots of clips according to the information in them. Now, I need to know which MovieClips were created below previous clips, and I figure that the easiest way to do so would be by extending the MovieClip class and add an order property.I have some problems though: I don't know how to set or get this order property within the main clip, I don't know how to place this clip within my movie, and I don't know how to create them dynamically (do I just do something like var myNewObjectOfExtendedClass : myExtendedClassName = new myExtendedClassName?)

I made the transition to AS3 two years ago, but I still carry with me old AS2 habits. Could someone please help me understand how I extend a custom class correctly. I have the bad habit of putting most of my code in one .as file (the Document class), but I use a few custom classes now and then. What I'm tring to figure out is how I would extend a class of this type:
public class ClipDragger {
private var _clip:MovieClip;
public function ClipDragger(clip:MovieClip) {
_clip = clip;
[code]....
For example I would like to add a MOUSE_MOVE listener, and also add actions to the drag function.
Is this possible? Extending From the Document Class?
Because I have this as code and can't get a trace[code]...
All I can find online are examples of instanciation, not inheritance when connecting/accessing the document root:
var mySubTest:TheSubTest = new TheSubTest();
Is extending from a document root impossible? I can create a new instance, but branching out seems like a dead end.
I'm having an issue extending a class in the JWPlayer API, but I think it's probably more of an issue of the way I'm extending the class in AS3 rather than the class itself. Here is the code:
Code:

import com.longtailvideo.jwplayer.events.*;
import com.longtailvideo.jwplayer.parsers.*;
import com.longtailvideo.jwplayer.utils.*;

All three of the final functions do not return values even though I have event listeners only calling those values one Event.COMPLETE (of the loaded SWF that contains this script).
am attempting to make a simple asteroids game using push button engine. In the game the ship should fire when the user pushes the spacebar button.To do this my KeyboardController class should make a new instance of the Bullet class on every tick when the spacebar is down.The problem is for some (probably simple) reason I can't extend the Entity or IEntity class. IEntity is an interface so I understand why I can't extend that, but I'm not sure why it's not letting my extend entity. Heres my code for calling the bullet constructor:
if (PBE.isKeyDown(InputKey.SPACE)){
var _newBullet: Entity = Bullet();
}
and here is the first line of the bullet class.
public class Bullet extends Entity{...}
By this question, I don't just mean add a final to your class name.I'm talking about, let's say that you have a class that only one other class uses, but should not be accessed by no other class. Is it possible to say in the extended class that only this other class can extend me?*Change* Also, can you restrict which classes are allowed to initialise it?
View 2 RepliesI have an AS file named MovieClipTLnd which I created to add a property to the MovieClip class, plus a function to trace the current value of the property I added. I works out just fine. But when I do the same trying to extend the Button Class, it won't work.

I know there are some workarounds for this problem... like embedding the button into movieclips and assigning properties as objects, but I need to know if it's possible to Extend the Built-in Button class itself just like it can be done with the MovieClip Class.
extending a class from MovieClip? I could just make a movieclip variable in the class to make it simpler. I heard if you extend from Movieclip it makes it feel like its dynamic because you have frames (gotoAndStop, etc). However, it allows me to have direct access to variables (or this.) instead of somemc., and I believe thats faster because 1) smaller name variable lookup, 2) no get function call.
View 1 RepliesI've been going through the OOP AS 2.0 tutorial here on Kirupa, and I was curious WHY this code is in a class which extends the MovieClip class and is used to affect a linkage item in the library:
Code:
// init method for arguments which in other normal
// circumstances (non-MovieClip classes) would be
// given to the constructor. Not an option with MovieClips

Is there something undocumented about why I wouldn't pass those parameters in when instantiating a new instance of the class in question? What is different about extending the MovieClip class?
I have class that subclasses fl.controls.DataGrid. The function below from the DataGrid superclass throws a compile time error (implicit conversion fl.controls.DataGrid to DataGrid) when the subclass resides in an unnamed package.If I place the subclass in a named package, the error disappears. If I use a different class name (e.g. DataGrid2), the error disappears.I never intended to leave the subclass in an unnamed package. However, I am curious as to why the unnamed package is preventing the compiler from seeing that DataGrid is a subclass of fl.controls.DataGrid.
Code:
public function addColumnAt(column:*, index:uint):DataGridColumn {
var dataGridColumn:DataGridColumn;

I'd like to write a class that extends String, changing the functionality of several methods such as charAt to incorporate the Welsh alphabet. The reason for this is that the Welsh alphabet is as follows: as you can see, some "letters" actually contain two characters, which messes up any charAt operations, etc.
Is it possible to extend String? When I try, I get "base class is final".
I found this thread on another forum which talks about doing this, but has no mention of it not being extendible:[URL]..

Initially I thought that I might be extending the class in the wrong way, but all the examples I found look the same.
I'm creating a class that extends another class.
public class ASClass extends UIComponent{

but I'm trying to make it extend multiple classes. Is this somehow possible? I read it may be possible through composition?
I don't how to describe the situation in short, so I am going to describe it in details.
I have created a class, extended from MovieClip. It looks like this:
// Libraries are imported
public class WindowObject extends MovieClip {
public function WindowObject():void {

When I clicked on the errors, they redirected me to the WindowObject class.If I don't create new classes, but just write the additional functions on the MovieClip directly, and set back the base class to be WindowObject, it works fine again.
