ActionScript 2.0 :: Variable Scope In Subclasses?
Nov 15, 2011
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?

I have 2 methods in a actionscript class.[code]I get duplicate variable warning. Is the local variable scope not limited to the method. Can't I declare same name variable in multiple methods?

Take a look at this code:
Code:
import mx.utils.Delegate;
class Test
{
[code]....
Well... Doesnt work at all... In the class, there isnt a instance of i, so, how may i access this property inside a class function? But i still have an way to access the class.
I could do this way:
Code:
class Test
{
function Test(mc:MovieClip)
{
[code]....
But this way, doesn't sounds good

I'm trying to make a Class for a slideshow. I have a problem using the setInterval and clearInterval methods.See my code below. In the showPic function I have a conditional clearing the interval (repeating the showPic function). At least, it should do so, but it's not working. The interval continues. I'm using "this" so that's not the problem. Maybe it has to do with the scope of the variable to which I assigned the interval?

I'm working on a sliding gallery like Hulu. Setting it up and the sliding slides in and out is working fine. However, I need to add and then remove a button to each slide as it comes in and goes out. (I initially tried including the button on each slide, a mc, but this proved problematic for the event listeners). So when the file loads up, I add a mc to the first slide of the group like so (features[] is an array of movie clips - my slides):
Code:
var goBtn:MovieClip = new FeatureButton();
features[0].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
So I add the button/mc to the first slide - works just fine.
So there are two handlers, next and previous. So I started with the next handler. The first thing I have to do is kill the button on the panel that is sliding out, so I do that like so:
Code:
features[featureCount].removeChild(goBtn);
goBtn = null;
(featureCount is a counter keeping track of the slides). This works fine. I click the next button, and the button on the slide disappears and we move to the next slide - perfect.
So then I add the following next - exactly like I did in the beginning:
Code:
var goBtn:MovieClip = new FeatureButton();
features[featureCount].addChild(goBtn);
goBtn.x = 350;
goBtn.y = 230;
This time adding it to the current slide coming in - but this generates the following error:
Code:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display::DisplayObjectContainer/removeChild()
at featuregallery_fla::MainTimeline/nextFeature()
How I'm getting an error on the removeChild() when that is already gone. I assume "parameter child" means goBtn - yes it is null because it's been removed. But I'm not trying to do something with that. I can only guess this is a variable scoping issue with goBtn - but I'm not seeing how to resolve it. Flash file attached.

I'm binding an array of items to a data grid using ItemRenderer. I use the data variable to control the bindable data. I also have someComponentVariable that need be inserted into every row but its declared at the component scope, so the data grid doesn't seem to reconize it (compile error). How can I use this variable (someComponentVariable) inside the ItemRenderer?

You will find enclosed a ".zip" file in wich there's a ".fla" file, a ".txt" file and 6 ".jpg" images. Frame 1 of the FLA only has a "Preload" class/constructor found on another site and works well. Frame 2 launches the graphic interface construction. The file "externalVar.txt" has one variable "maxVin" with a value of 6.
I would like to know WHY i can't acces this variable from outside of the loadVars object's scope (i would better say from outside of its ".onLoad" methode scope). In fact, when i trace my variable "maxVinNum" from outside of this function, flash player return "undefined". Even if i declare "maxVinNum" on the _root (_root.maxVinNum). For information, at the start of frame 2, i have let an instruction in comment: //var maxVinNum = 6; When we activate this instruction, then the variable is directely declared and everything works well. This test allow us to verify that scripts are not bugged. Here is the script of frame 2, some of you may understand quickly what's wrong :

In the code below, I'm looping through nested xml structure of an unknown number of levels. GenMenu is (or will be) a recursive function that will build each level of the menu. My problem is that I can't figure out how to reference the variables from an eventlistener function. I need to pass the children node_xml[i] to the next recursion, as well as set hover styles on the menu links, etc...
Code:
function GenMenu(container, name, x, y, depth, node_xml) {
// variable declarations
var curr_node = new Array();
var curr_menu:MovieClip = new MovieClip();
addChild(curr_menu);

I'm not an experienced Actionscript user so I'm not sure what the normal way to associate a custom class with a movieclip that has been designed in the Flash IDE is. I made a class called Window to control a movieclip called TestWindow. There are some buttons in the movieclip whose
functionality I would like to assign the instance of class Window. How is this supposed to be done? Here's a representation of what I mean. I hope it is sort of clear. My actual problem is that the local variables are outside the scope of the onPress function but I also think there must be some other way of associating classes with movieclips that have been designed in the IDE.

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).

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.

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);

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?
