ActionScript 3.0 :: Where Is Document Class In Parent/child Hierarchy
Jan 19, 2011
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.

i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).

I'm using a PreLoader as a parent SWF that loads the actual website as a child SWF. In the website SWF, the child SWF, will MovieClip(root) still work and refer to it's own root, or the PreLoader's root? And would I still access the websitite's document class (the child's document class), through MovieClip(root)? What if both files have a document class?So my main question is how do document classes and MovieClip(root) behave in the scenario when you have:
Parent SWF - document class, MovieClip(root)
|
Child SWF (loaded by parent) - document class, MovieClip(root)

I've got this interactive poem I've been working on for a class. I've basically finished each "episode" seperately. I made a parent document which essentially loads one of the ten child documents onto the respective key frame. Here's a sample of the code for the first key frame of the parent document:
stop();
import flash.net.URLRequest;
import flash.display.MovieClip;
import flash.events.Event;
stage.addEventListener(Event.ENTER_FRAME, LoadSWF2);
[Code]....
Well Two things are messed up about it, well my "ChildTimeline2" variable will off and on assosciate itslef not with the main time line of a child document, but of a nested symbol inside said child document. Even worse, the "gotoAndStop();" command I will give sometimes applies to Parent document... yaay! but often it will apply to the child document. The end result being this horrible looping moment where you are stuck in one child document for all time.
I wish I could attach the documents but they exceed the 300KB. how I can get Actionscript to listen fro the last frame of the maintimeline of the child document, or tell flash to gotoandStop for the parent document

I think this is a pretty simply problem but I do not seem to be able to pull it off. Basically I have a parent class A, and a child class B.Class A instantiates class B with addChild.There is a shared object which is being updated from a java server (red5) that has an event listener attached to it in class A.I have a function in class A which will pass certain, specific updates from this shared object to class B.The problem occurs is that when class B is instantiated, the event listener from class A doesn't work anymore. I have not removed the event listener from A.?

Lets say I have a Main Document Class called Main. I also have a child class called childClass that call a function from the Main class and is also imported in the Main class. How should I call the function? I tried this , but when calling the function, it's getting me error.

Code:
package {

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:
[Code].....
And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.

Setting properties of a nested clip from the associated document class of the parent clip. I am developing a Jigsaw puzzle in Flash. I am developing a class for puzzle piece. The code of the PuzzlePiece class in given as follows.
PuzzlePiece class
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class PuzzlePiece extends MovieClip {
private var pieceX:Number;
[Code] .....
Is it wrong to access it like that. The PuzzlePiece is the export for a puzzle clip. For the time being I am hard coding the dimension as 60. I have aloso uploaded the fla and as files. [URL].

I have a document class with a child MovieClip on the stage. I have the clip already on the stage because it's part of an complex layout provided by the designer and it seems easier to leave it on the stage than to use addChild (since I would have to add about 60 objects).What is the best way to reference the document class from inside the child MovieClip class?

i m getting an error, i am loading an external child swf file to main parent swf, and want to access the document class of the child swf through parent swf document class using application domain. Now when both child and parent swf resides in same directory it's works properly with application domain means we can access the document class of the child swf see the attachment samedirectory.zip and when we move child swf and it's document class to sub directory that time we are unable to access the document class of the child swf see the second attachment subdirectory.zip

I've been using greensock classes in a parent movie, but am now looking to use the same classes from within some child movies, but it doesn't work (I presently have to import them into each child movie - what a waste).
Do I need to create the classes as a shared library object perhaps? If so, how would I go about it? as I've only ever done this for MCs or MP3s.

I have a SWF with a document class called ClassA. I'm loading in an external SWF with a document class of ClassB. Then ClassB is loading in an external SWF that is used for graphical assets.
The problem is that all of the assets in the third SWF all extend a class called Actor. The assets swf is loaded and set as the var "_assets".[code]...

here is the scenario we ran across while working on our Flash AS3 project today.
/main/root.fla
/main/root.as
/main/sub1/sub.fla
[code]....
We have many sub swf's that are loaded by the main root swf. The root swf shows the art on the stage of the sub swf, and also runs some code from the sub swf's document class. However, we noticed the constructor was not getting called on the second sub swf if the document class is the same name- even if they are in different folders. Note that we publish our swf files to a separate directory (with the same structure as above) so it is easily copied to the web server.
-root.swf loads sub1/sub.swf
-the constructor of the document class sub.as in subfolder sub1 gets called
-root.swf shows sub1/sub.swf assets with the correctly constructed sub1/sub.as document class
-user chooses to switch to sub2
[code]...
We decided to use a workaround where we basically changed the two document class .as files to be different names (e.g. renamed sub1/sub.as -> sub1/sub1.as and sub2/sub.as -> sub2/sub2.as, and updated the .fla's to point to the renamed document classes), and it works as expected. Hopefully that workaround is useful for someone.I realize most people just name every single file differently and keep everything in one folder, but when you have a sufficiently complicated project, things like this come up.

I am new to AS 3 and I tried to solve this (probably really simple) problem, but I couldn't, so I gotta ask here. All I did was create a child through a function in my document class.It is in fact an altered version of the rotate circles tutorial from kirupa.

function makeCircle (e:Event):void {

I wrote two projects using the same 3D library but I modified it pretty heavily in one (to the extent that the inheritance is pretty different on one) - now I need to load one into the other and I'm getting some weird errors that look like the child swf is trying to use the same class definitions as the parent even though it should be in an entirely different namespace.
So - anyone have a tricky way of forcing the loaded swf to use the classes it's compiled with rather than the ones already defined in the parent swf (and vice versa) or do I need to refactor all my stuff?

If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request?In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?

i know this may seem kind of dumb, but how does one access the document class from a child movie clip on the stage?
i have a property in my class. Just a string for testing:
Code:
public var s:String = 'can you see me';
it traces on the root time line, but it errors out if tracing it from a movieclip on the root time line.

[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]

i've got an inheritance chain of AS2 classes set up where i have an array in the 'child' class that i'd like to be able to access from the 'parent' class:
bottomClass.as -'parent'
topClass.as -'child'
my question/dilemma is: how can the parent access the properties of a child class...is this even possible, or am i just looking at it wrong?

Let's say I am loading a movieclip from a remote url within another movieclip on another server.
This movieclip now needs to load another child movie clip on the same server as itself.
How can it get its own url and not the url of its parent container so as to load this child ? Because if it refers to "child.swf" it will be relative to the super parent container insted of the first server isn't it ? So it will not be able to load the child correctly if all it can get is the url of the parent.

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".
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 have one movieclip object with a custom class.
That class has a loop that creates / instantiates a number of copies of another movieclip from the library. This second movieclip has a textfield child in it. When I convert this textfield to a movieclip I can access the properties of it fine, but just as a dynamic textbox I can't access it.
This is the custom class of the second movieclip that gets instatiated a few times by the first custom class...
This custom class relates to a movieclip that has a child MC called recent_text (which I can access ok) and in that child is another child (a dynamic text field called "aDynamicTextBox", which I can't access)[code]...
