Trying to find a straight answer for this. I am going to be creating some sub classes in actionscript 3. I was wanting to know if it is possible to override the parent class. If so, do I need to put a override assigner on the parent class method or what.

This is a little odd but I need to know all subclasses of a specific class. So let's say I have the base class called Shape and 3 subclasses (Circle, Triangle and Rectangle) that implement it. I would like something like this :
public function getSubclasses(aClass : Class) : Vector.<Class>
{
//???
}
that returns a vector containing Circle, Triangle and Rectangle.I unfortunately cannot count on the fact that each subclass be instanciated at least once before that function is called.t the moment I need to manually add the classes to a list but this is error prone (if I forget) and also not as versatile as the function proposed above would be (since I would need to make a new list for every class I want the subclasses of).
I have been assigned to work on a Java/Flash/BlazeDS project. When I pull down the project code, I need to run an Ant script as part of the setup. This script eventually compiles the Flash code, as seen below.[code]...
View 1 RepliesI've seen methods for overriding addChild inside of movieclips, but can you do it at the upper-most root level? As in, overriding it on the main timeline.
View 3 RepliesI want to override the dispatchEvent method while inheriting from flash.display.Sprite. Whenever an event gets dispatched now like ADDED_TO_STAGE and CLICK it will get through dispatchEvent in my theory. However there is no single trace he'll get through dispatchEvent.. so the events get dispatched internally from some where else?
[Code]...
In the below example, stage is always null. If I move the listener for enterframe to TestSubClass, it obviously works OK (even if the added function remains in TestClass?) - but why can't I detect stage in TestClass and reuse that code for all classes that extend it?
Some code:
Code:
// ParentClass
var testClass:TestSubClass = new TestSubClass();
this.addChild(testClass);

I've been having trouble with scope in subclasses, where variables that I would like to be local to each instance of a class are instead global. For example:
Code:
class Prototype extends MovieClip {
//Various functions all clips have access to
}
class Ship extends Prototype {
[code]....
I've found that if I instantiate more than one ship, the hitboxes array is populated with clips from every instance of the class, instead of staying local to each instance as I'd like. Is this because I'm attaching them with a constructor?
how subclasses, instances, and inheritance work. The below code isn't actual project code, it's theoretical code, generalized to a simplistic level so that we can talk about the big issues. I have animals_app.fla, with a "Dog" class MC and a "Cat" class MC. Both "Dog" and "Cat" are subclasses of "Animals"; animals_app.fla uses document class "Main".
Intuitively,I think Animals should declare that every subclass should have some animalSpecies ,and each subclass will define the value of its own animalSpecies. It wouldn't make sense for Animals to provide any default value, because it will always be different per subclass.Is this correct?
I had tried out some code similar to that below, and was perplexed because it seemed like whenever a subclass tried to define a value for its own animalSpecies variable, it was actually changing the value of the variable in the Animal class, but that's not what I want. How do I rewrite this code so that each subclass defines the values of variables it inherits from its superclass, without altering the superclass? And how would I define the value of variables for each instance of a class, so that I'm only changing the values of that instance, without altering the subclass?
Animals.as
package
{import flash.display.MovieClip;[code]..........
Also, conventionally, what should be in my Main class? Only the addChild code which attaches MCs to the stage? Or should the values of variables be defined in Main? What am I missing?I recently read Foundation Game Design with Flash and didn't feel like the explanation was sufficient.

I'm trying to access a MovieClip object in a SuperClass from a SubClass. The only way I can tell this is possible is through an event dispatch, but I'm dealing with a preloader and a loaded external SWF. So I can't make an instance of the "not yet loaded" classes because I'll get errors. Furthermore, the objects in both SWF need to be controlled in sync.

I'm trying to create a base class for components by extending Group in Flex 4, but I can't seem to define the layout through MXML. Any time I try to move the definition to a subclass of my base component, I get the following error:
Error: Could not resolve <s:layout> to a component implementation.
Judging by that error, it seems that some magic from the framework's side goes into assigning it for a Group and thus the compiler fails when trying to assign it for any other classes. Does anyone know how this is supposed to work? how to allow me to define it in subclasses?

This doesn't compile. Say, you don't have control of the base class, what ways is there implement the same thing? The obvious is create a function setSpace(), but this object is being embedded in an already existing system that use the public space.
I would like to create many different labels which have identical properties but which have a different position and a different name. I created a main class called DefaultLabel which defines the format of a standard label and then I created a seperate class called Label which overrides the createLabel method with a different position and a different label text.
Ever since I added the Label class, my original label doesnt appear anymore and I receive error msgs (1119) stating that my formating properties (text, color, etc) are not defined and that they reference to a static type Label. Unfortunately I do not have Flash installed in English so I cant give you the original msg. Everything worked fine when I just created one standard label so I guess I made a mistake with overriding...
The various labels should be created in this class:
PHP Code:
package {
public class Label extends DefaultLabel
{
private var myLabel1 : Label = new Label();

View 4 Repliessuper.zValue(n) should be super.zValue = n ........ wowy Nothing to see here folks, just keep moving on I'm having some difficulties in working with the as3 way of overriding methods.. specifically setters. I'm a recent convert from working with as2 for a few years, so some of these quirks are beyond me right now.Here are my two classes:class tempBase in package core
Code:
package core
{
import flash.display.MovieClip;
public class tempBase extends MovieClip
[code]....
I do not have any errors for the override of baseFunction, but on compile I get the error 1061: Call to a possibly undefined method zValue through a reference with static type core:tempBase.In as2, this would have been perfectly acceptable (even without the override function), and was incredibly useful in creating my class structures.
I recently started on a new portfolio site and can't seem to figure out why some of my swfs override the html pixel size. I have included a link to the page. When you click on 'portfolio' there should be three thumbnails on the right. When you click on one of the thumbnails you'll see the size shift.
upload the xml files as well.
I frequently find myself wanting more granular control of the width/height properties. Consider either of the following cases:
- The DisplayObject is clipped with DisplayObject.mask, but Flash reports unmasked width.
- An image is displayed with a transform cage drawn over it. The width of the cage shouldn't be calculated when determining the DisplayObject's width.
The naive way to solve this problem is to override the width getter of the DisplayObject in question. The problem is that the core implementation of DisplayObject.width is written in native code. If after overriding the width getter, I call overridenObject.width, I get what I want; however, if I call overriddenObject.parent.width, DisplayObject.width ignores my override and calculates the dimensions based on its own internal display list representation.
Does anyone know of a technique to limit which children are considered when calculating width without having to override every parent's width getter? I've tried overriding width, getRect, getBounds, and scrollRect, but none of them seem to be referenced by DisplayObject.width's native implementation.
I'm an animator trying to use actionscript along with timeline animation.The setup is flock>fly>wings flock movieclip 30f long, the script looping, starting multiple fly movieclips at different points.
fly movieclip 30f long, controls wings0 movieclip timeline (3 frames, each with a movieclip). Frame1: wings0.gotoAndStop(2) Frame24: wings0.gotoAndStop(1) Frame48: wings0.gotoAndStop(3)
From flock timeline I'm trying to override actions in fly3. to call a different wings0 animation.
flock Frame1: var loop:Number = 0; fly1.gotoAndPlay(15); fly2.gotoAndPlay(8); fly3.gotoAndPlay(20); if(fly3.currentFrame==24){ fly3.wings0.gotoAndStop(3); }
flock Frame 30:
loop = loop + 1;if (loop > 0) {this.gotoAndPlay(2);} else {this.stop();}
But the animation of fly3 doesn't change.

View 2 RepliesI have a class (Wall) that inherits from Sprite.Sprite already has width and height properties.

is the only alternative to create my own connect-like method with my own parameters, call super.connect from this function and override the stock connect function to throw an error if it's called?
