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:

function Test(mc:MovieClip)

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

ActionScript 2.0 :: SetInterval, Classes And Variable Scope?
Jul 27, 2005I'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?

ActionScript 3.0 :: Parameter Child Must Be Non Null - Variable Scope?
May 5, 2009I'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.

ActionScript 2.0 :: Can't Access Variable From Outside Of The LoadVars Object's Scope
Feb 23, 2004You 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 :

ActionScript 3.0 :: Recursive Menu And Variable Scope With MouseOvers
Aug 7, 2009In 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:

// variable declarations
var curr_node = new Array();
var curr_menu:MovieClip = new MovieClip();
addChild(curr_menu);

ActionScript 3.0 :: Associate Custom Class With MovieClip - Variable Scope
Oct 25, 2008I'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.

View 1 RepliesActionScript 3.0 :: Memory Leaks - Variable Reference Inside A Function Or Outside It?
Mar 11, 2009I wonder what the most common reasons for memory leaks in AS3 are.First thing what I am not sure about is: is it better to have a variable reference inside a function or outside it. Will the variable be null-d automaticly inside a function or when do I have to null it and when not?I have massive problems with my game with memory leaks. I noticed I reference some of the clips of the timeline even inside my debugging clip to display propertys and this was causing collecting huge amount of memory.But even before I go into the game with bigger objects the System.memory is slowly growing and growing.I just have a socket connection and some interval loops and enter_frame events.

Am I correct in thinking that each time I created a new Sound I would be overwriting the previous allocated memory?
ActionScript 3.0 :: Local Variable Physically Exists (in Memory) Outside Of The Function?
Dec 23, 20101- Variable Scope : Accessibility and existence are used almost interchangeably in various documents I've read. I'd like to know if a local variable physically exists (in memory) outside of the function it was declared in, and is not accessible from other methods, or if its existence ceases outside the function.

View 2 RepliesActionScript 3.0 :: Learning About Scope And Packages
Jul 15, 2009I have made a script, and now has come the point when I need to use removechild. Whenever I try this I get an error. After looking at the problem, I think I need to learn more about scope and packages. I think if I put everything in the correct scope, I will be able to use the removechild command. I tried to make all my vars public, so that removechild would work, however I got an error that anything public needs to be in a package. I tried to add the package part to my script, but got the error that packages cant be nested. I tried some other things and still no luck, just more errors.
So, if anyone could point me to a tutorial, or recommend a book or something, that will help teach me about scope and packages, Or if you are feeling patient and generous, and you think you could explain this problem to a 5 year old, please explain it to me the way you would to said 5 year old.
