ActionScript 3.0 :: Create Movieclip Class That Subclasses Another Movieclip Class
Sep 3, 2010
I want to create a movieclip class that subclasses another movieclip class and inherits all its properties (rather than having to rely on the include statement). In my project I'm using:An abstract parent class that extends a movieClip: "infantryDroid".[code]However everytime I try this, flash acts as though nothing was imported from the parent movieclip class.If I was to try the above code I would get the message that _root and speed (which were defined in the parent class) "are undefined".

I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

I'm trying to write a class that will create my movieclip buttons dynamically, and assign some text to a dynamic text box inside it, based on the argument I pass to the method in this class. I've got a movieclip in my library with the linkage shown below - And I've got this so far in its own AS file -
Code:
package com.willgoldstone.tutorials {
import flash.display.MovieClip;
public class Mybtn extends MovieClip{
[code]....
All I want to do is instantiate a copy of this movieClip in my library and assign a value to its dynamic text field..

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).

If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.

Ok, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?

How can I run function of the main document class from a class of a MovieClip? I usually just used MovieClip(parent).function(), but now my MovieClip has another parent. Or what do I have to pass to the MovieClip class when creating the MovieClip to acess the main document class?

Is there a way to refer to a Movieclip on the stage from a class file of the document class
Lets say I have 3 MovieClips on the stage(a Circle, a Square and a Triangle)
I have the document class which calls another class that controls the MC on the stage
Example
ActionScript Code:
package {
public class Example extends Sprite {
//Create the instance of the class being called

I'm creating a mask effect. i create 10 movieclip with a library class reference that appear on the screen with a random alpha effect. THe problem is that if i try the effect alone all works ok. if i mask the layer that contains the effect on an image i don't see the effect. i see directly the image masked with the boxes. i can't explain that because i've the effect first but it seems that when i test the movie the effect doesn't play and the boxes appear directly on the screen.

I'm trying to build a shuffle function that somebody gave me into my card game. I two external .as classes; one is Shuffle.as, which is my document class, and the other is card.as. I'm building the shuffling function into Shuffle.as. I think I'm getting close to making it work, but there are some problems. I keep getting this error message: "5000: The class 'Shuffle' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type." Here is my code. Shuffle.as code

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 am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG();
var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.

I'm new to Flash AS3. I started making a game and I am a bit confused. Let's assume that I want to create a game that has multiple levels/modes, how can I do this in an object orientated way?
When i create games in other languages e.g. XNA C#, i create a separate class then create an object of that class within the main class and run the game based on a simple statement.
