I want to break my code into several classes for the sake of readability and reusability, but I keep getting various errors for code that works perfectly well when it's all contained in the DocClass.

Is it possible to create Abstract classes in AS3?
In other words, is it possible to declare a virtually pure method in AS3?
For instance, from my C++ knowledge, is it possible to do something like this in AS3[code]...
Im building a project using an MVC pattern. I have (pseudo) abstract classes Model and View, each extended with particular models and views. But I cannot access properties on the extended classes of Model...Model simply distributes XML data, heres its constructor:
Code:
public function Model(data:XML)
{
_data = data; /*_data is a protected var of type XML in Model*/
}
MainModel extends Model, and has a property called _background of type Background which also extends Model:
Code:
private var _background:Background = new Background(some XML source);
public function MainModel(data:XML)
{
[code]....
The problem arises when I try to pass MainModel's background property as a parameter of _bgView (highlighted in red above). The compiler says there is no background property on Model, which is true, but I need it to look at its extended class MainModel, not Model. I've typed MainView's constructor parameter with MainModel, but it is still seeing it as Model.

How should I set my Local playback in publish settings? Access Local Only? or Access Network Only?
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);

I'm building a demo that has a keyboard in it. Obviously, people will type stuff with it and it will go into a dynamic text field. So I have a full keyboard (a movie clip named "keyboardStandard") made up of button symbols. That is placed in the same frame as the text field. Then I wrote this code, using the Q key ("keyQ"):
Code:
keyboardStandard.keyQ.addEventListener(MouseEvent.CLICK, addQ);
function addQ(ev):void {
enterPlayerID_txt.appendText("Q");
}
This works just fine, the Q goes into the text field. However, I sure as heck don't want to write 26 event listeners, then 26 more functions, even if it is copy paste. That's just gnarly. Plus, there are actually 3 keyboards - a numeric and special char one as well I need to handle.I seems passing a parameter from the event listener is not doable?
I am now trying to make a flash intro for my web site.I have downloaded some free templates for the same and examined them.Some special effects, means colour abstrract moving effects or explosion like effects are in that 'fla' file.They appear as movie clips. I can export them as flv also.How they are created? Is it in flash itself or from some other programs like after effects or something?I would like to create such effects for myself. If it is not in flash, then there is no point in wasting time figuring out the methods by myself.
View 6 Replieswhat is the keyword that allow me to implement an abstract class? It was asked in my interview..Can you say it from both java and ActionScript(flex)
View 2 Replieswhats 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 3 RepliesCan it be done in flash with some of the glow filters? Or is this probably being created in something like After Effects or Motion and then being pulled in as JPEG StillsI've looked through some tutorial sites, but most of the animation tutorials are pretty basic... and I'm not sure what to really call the effect...making searching for tutorials or forum posts a bit tricky
View 5 RepliesI apologize in advance if my question is not clear, because I don't know how to put this. What I am trying to do is to reduce few lines of repeated code by implementing various OOP methods/concepts.
The problem I have few set of of classes which has initialization process. So, I am implementing an init() method in all those classes. From the calling class (main), these objects will be instantiated and init() method of each object is called in the the order and call some other process after all of them are initialized. Something like this

what I meen is to get all objects and their properties, is it possible? How to do such thing?
View 2 RepliesIs there any way to auto-import as3 classes (internal/intrinsic Flash Player classes at least) using Emacs ?
Looked for as3-mode and actionscript-mode but nothing working was found. as3-mode can import class if it is opened in buffer (but not *.mxml files)
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).

I'm trying to import a class from a class that is located in another folder. How do you move up a directory? Using./ or ../ doesn't seem to work. Essentially I want to access a TweenLite Class but not from the document class. My class is at com/myName and the class I want to access is at com/TweenLite. import ../TweenLite doesn't work... I realize I could just copy and paste the entire Tweenlite folder again, but there's got to be a less duplicative way of doing this..
View 2 Repliesinheritance and building classes from other classes.
I have 3 classes:
gfxRoomText - changeable colour
gfxRomInter - changeable colour - interactive
gfxRoomImg - interactive - only image / no colour
The first two incorporate the same text field and functions to change colour. The second and third incorporate another class to interactive with. What is the best way of creating these classes using inheritance and how?
I have to use many custom classes for a project, each class includes lots of elements(methods,properties) and I generally forget their names when coding. Is there any editor which I can enumarate the elements of my classes after pressing "." like Flash's built in classes?

View 2 RepliesI am new to classes and I am just starting to follow tutorials on how to assign classes and sub classes and I am wondering when you assign a base class or class to an object(Symbol e.g movieclip) through the properties, are all instances on the stage no matter how many and what they are named influenced and is the Stage/main timeline always the parent? and just one more question, is the parents objects display list all the movieclips that are used on the stage or all the instances on the stage?

I've created a base class to house some basic functions I'd like to have across several movie clips in a game I'm making, however, when I link a custom class to the same movie clip I get the message; "The base class will not be used because the class specified is already defined and extends its own subclass. If you wish to use the base class, specify a class name in the Class field that will be auto-generated or enter the default base class 'flash.display.MovieClip' in the Base Class field." I removed the 'extends MovieClip' inside the Class but it still shows the message. Does this mean that I cannot use a custom class and a custom base class on a movie clip?
