ActionScript 3.0 :: Traversing A Class Hierarchy?
Jun 9, 2010
I'm currently working on a tower defense game and am in kind of an odd situation. I've programmed it in such a way that a large class hierarchy is in place. It's like this StartScreen class ---> BaseLevel class ---> GUI class ---> TowerPlacer class(towers are stored in an array in this class) ----> etc.My problem is that i need to access an array in BaseLevel from my GUI class, is there any fancy trick for doing this? or have i screwed myself over.

I have a class1 in which I create a child from a class 2. Of course I can access class2 properties, fields and methods from class1. But is there a way to access class1 fields and methods from class2? Like to go a step back in the hierarchy?

I have a class linked with a movie clip, and in this movie clip I want to be able to add an event listener that calls a function in the Document class (the class you link with the fla as a whole). How can I do that? Say the name of my document class is KPScript.as. In my GameController.as class, I want to listen for key input and call pageChange() in KPScript.as when it gets called. Would I have to import KPScript.as into the GameController.as? If so, I wouldn't want to create another instance of the KPScript object.

Im making different quizes and small games. I always use a Document Class when coding, and usually i call this Main.as. Usually the Main.as contains pointers to different classes like:
private var _menu:Menu;
private var _messageBoard:MessageBoard;
etc..
My question/scenario is this: In for example _menu, i have a button that has an event listener on it (example: "Start" button). When this event is triggered (ie user hits "Start") I want to trigger a function in Main.as. How is the most elegant way of doing it? The solution i use now, is that i send a reference pointer of Main.as to each new class i make. ie in Main I would do something like this:

I have spent multiple hours on it to find no result. Here is the situation. MY xml structure looks like this:
<root>
<RES>
<R N="1">
[Code]....
But I am not able to refer to the corresponding parent <R> so that I can traverse it to retrieve corresponding <SEZ N="name" V="dummy name"/>

First of all, this is not specifically for homework. It's a project I've been working on for the past few months and I've kinda hit a road block. The short version: I've got a Flash file (which is a DJ program) whose main functionality is to play mp3 files, load the files a user uploads into a web page I made and let the user have the ability to choose which song they would like.
I literally have this almost completed except for this final piece: playing what the user uploads. More details of how I got here: I've got a PHP page that creates (or updates if you wish to call it that) an XML file. I'm not sure which way I should approach it (most tutorials online show AS2 but I've already made my project in AS3 and I've seen it's easier...yet I'm not able to figure this out).

I have 2 classes Main.as and RedPawn.as (yes, in the same folder).I am wanting to check if a child exists on a movie clip in Main.as through RedPawn.as.This is within a for loop since I am checking 24 possible values for _dest until I find a match.This simplified code example would be in the RedPawn class:
Code:
_dest = 'example_mc'; // example_mc is pulled from an array
if ( MovieClip(root)._dest.numChildren < 2 ) { // do stuff; }

I am experiencing problems when trying to traverse XMl returned from the youtube data api.I can trace the XML but cannot access any of the nodes, not sure where I'm going wrong, I have tried various methods including parsing JSON format from youtube but to no avail. I thought it maybe the namespaces so I replaced these using a script to replace them as attributes. A snippet of returned XML is below:

I've been searching around forever trying to find a way to make traversing nested display lists more of a 1-line possibility.In AS2 you could grab a clip just by _container.clip1.nestedclip2.nestedclip3 and it was blatently simple.In AS3, is there any way to do that?So far my only methods are keeping a class level reference to important parts of the UI or doing a painful series of getChildByName chains until I drill down to it:[code]The casting makes the getChildByName method possible.

I've created some classes for a nav menu and I'm having some trouble dealing with the click. The bottom class of the chain gets the click, but I need to pass that event up a hierarchy of classes to the very top so it can get handled.My hierarchy looks something like this:
AllMenus
- MenuBar
- - MenuItem

I have
level 1: <Element>
level 2: <a>some content</a>
</Element>
<a> is nested in <Element> and I need to delete <Element> without deleting <a>. So basically I want <a> to be the parent element of itself.
Like this:
level 1: <a>some content</a>

Where do I place a function, at the lowest level, so I can call it from any other container above it? For example, I have 3 frames and they all need to use the same function, called "myFunction()". Do I really have to create it in each frame? There has so be a lowe level where this can be placed? Is there a good simple description of AS3 Hierarchy somewhere? Also, how do you specify global variables in AS3?

There are a few mc's already on stage that I've attached dynamically to _root. Now I want to take one of them and attach it into some other mc on stage, also attached dynamically. I want to retain the position, width and height of the former mc. Is this possible? some way to manipulate the pointers or addresses? Can I manipulate the ._parent property?

When I click on a menuitem, I wish to print out the selected item, but in the form of (for example if I were to click Madone 4.5) "Road > Madone > Madone 4.5".

I'm trying to make an onPress function for a MC inside a MC and I have figured it will look something like this:
_root.mc1.mc2.onPress = function(){}
It won't work though. What to do? (Now I see, I have that mc2 on the 2nd frame inside mc1... if I put it also on the first frame it works fine, but I don't want it on the first frame).

To give a brief background of what's going on here.I am building a personal site where I have a navigation, and I have other subnavs inside of certain pages.Such as if I go to "work" inside of work i have "motion", "web" & "print".Here is some example code of one button on the navigation:
nav_mc.personalbtn_mc.addEventListener(MouseEvent.CLICK, buttonClick2);
function buttonClick2(event:MouseEvent):void {
gotoAndStop("personal");[code]...
It seems to me that actionscript will not read all the way down to the bottom when looking for objects.For example: The first if statement where it's asking if workss_mc exists or not, that will work if it's at the top, but if I move it down to the bottom it will not work.

I have two components being absolutely positioned within a container (they are MapSymbols on an ILOG Elixir map, if that helps). Each component is a VBox with an Image and a Label. Images have functionality tied to the Click event; labels do not.
The problem is when 2 items are positioned so that the label of one is above the icon of another in the z-index, so that the label eats any mouseOver and mouseDown events. Bubbling doesn't help since it bubbles from the label to the vbox to the container, never hitting the lower element. I can't set the vbox to mouseChildren="false", since that keeps the image from getting clicked, as well.[code]...

I have some FLA/SWF assets which are hierarchies of bitmaps.They have timelines which page-flip through different bitmaps.I'd like to scale these assets down in pixel-size, including the bitmaps they're composed of.I'm not a Flash Animator, but the artist i'm working with doesn't know of an automated way to achieve this. ie, that it's a long a laborious manual process.Does anyone know of a tool which can simplify the re-scaling of bitmap-based FLAs ?

I'm having a problem with remove child in certain areas.. One would be when I load one page from the navigation then go to the "WORK" link, work won't show. Also..when I remove a movieclip elsewhere(this is under the same circumstance) then click on a link it does not remove that movieclip that is loaded again.
For example, click personal, click a thumbnail,(this adds workpersonalss_mc) then click back(this removes work personalss_mc then adds workpersonal_mc back), the click a navigation button it still remains..

I am confused as to why on your C Drive the folder structure in regards to classes in flash does not seem to resemble the hierarchy/structure when you are actually using them? For example, I kind of expected there to be a Classes folder with Top-Level Classes, then two sub folders, the fl. folder and flash. folder, and in them, packges...etc...
Instead there is a "FP7" folder, "FP8" folder, "FP9" folder, "FP10" folder, an "mx" folder, and a toplevel.as class. FP7 and MX seem to hold a lot of the primary classes that I am most familiar with...but how do they relate? I thought I would find the Sprite class in a display package/folder...but have yet to locate it (my search feature is weird at the moment, I am not sure why it can't really even find anything, even though I know that that thing exists).
How does this relate to the hierarchy / structure of classes when you are using it? I am basically trying to visually things but am confused. I may need to explain a bit more later... how to put into words at the moment...

I have a class called Bike.as, linked to a movieClip in the library. The class essentially tweens a bike graphic across the stage. At the end of the tween, I instantiate a new class called Slideshow. Slideshow loads an image. The image loads(I get no loading error, and I can trace info about the loaded content)... I just can't seem to see it. In attempting to debug, I wrote the loading code(in Slideshow) into the Bike.as file(replaced the code that instantiates Slideshow), and it worked. Did it work because Bike is linked to a movieclip, and Slideshow is not(Slideshow is called in Bike.as)? I'm attempting to transition from AS2 to AS3. Here's my Slideshow class:
public class Slideshow extends Sprite {
private var container:Sprite;
private var loader:Loader;

I am trying to animate using a heirarchy of symbols and motion/shape tweens for the first time. I have my character built using symbols and groups of them are already in subgroups (I click on one symbol and I can go into that one and there's more inside that). When I go into my character's eye symbol and click the upper eyelid, I can shape tween a blink. It works fine when I scrub through the timeline while still in the character's eye symbol and it still shows up when I publish a preview. But when I go out of that symbol to the top of the hierarchy and play the animation in the frame, I can't see the blink. I don't know why it's happening, but I can't edit all my shapes without knowing where the ones I've already moved are.

say an application has panel and panel has button and textField or textArea. we click on a button to hit a service say via cairngorm framework.
The Events lifecycle follows the capture-target-bubble cycle in the display hierarchy like the MouseClick event on button will call the handlers for the listeners attached to button and/or panel and/or application and/or stage since the flow moves in this direction.
How do the event on non hierarchy works e.g the result from the service fires a custom event DataRecieved. we have a listener attached to the panel/button for this dataRecieved event. How do this listener gets the information? how the event lifecycle comes into this picture?
