Actionscript 3.0 :: Using AddChild In OOP?
Mar 7, 2009
I'm new to programming in general, so not only are the basic concepts new to me but OOP and all of the various underlying rules are keeping me very frustrated in this learning process..I've reached a point that I'm simply stuck and can't find the solution through trial and error, and perhaps am not grasping how addChild works. traces just fine, but then when I try to run addChild I get "error 1023: stack overflow occurred: at Bullet$iinit()".Ignore the commented out lines, they're just for some testing and some trial and error).
//Bullet Class
package {
import flash.display.MovieClip;

I'm trying to have a class file which can add objects to the stage via addChild; however, when I call addChild from within the class file, I get the error "1180: Call to a possibly undefined method addChild." I've tried importing flash.display.* and that doesn't fix the problem. Does the class file have to extend Sprite or MovieClip to be able to add objects to the stage?

I have downloaded Box2d ([URL]) and created a project that looks like this: [URL]. catalyst is the green cube and it has the base class "shapes.box", it is inside "world" which has the base class "wck.World". What i want to do is to add another "catalyst" from the library inside "world" when i click on add_btn. I tried to accomplish this by this code:
[Code]...
Symbol 'buttons', Layer 'Actions', Frame 1, Line 41061: Call to a possibly undefined method addChild through a reference with static type Class.

I have the followings:
_p:Player (which is a MC)
a1:Animation1 (which is a MC)
_p.addChild(a1); //doesn't display anything
_p.stage.addChild(a1); //displays a1
Why won't the MC display a child without using his stage?

I'm trying to resolve an issue that reared it's ugly head yesterday.Frame one of main timeline I have the following code:
Code:
import flash.display.MovieClip;
import flash.events.MouseEvent;
[code]....
The newMC doesn't show up.If I add 'parent.' in front of the addChild then it appears.mc_LibItem has a base class of "flash.display.MovieClip" and is exporting for ActionScript and on frame one.For grins I created a new .fla and began messing around with the same addChild idea and it worked.

somewhat understood the basics of adding and removing children, however, I am facing another problem. After using the removeChild Function, I can't seem to add another child.For example:
ActionScript Code:
var attachedMC = new (getDefinitionByName("Content1") as Class)()
Page.addChild(attachedMC);

I have a main "shell" swf which, by clicking several buttons, will load/unload various external swfs into a Placeholder_mc which resides on the main timeline in Shell.swf In the documentation and tutorials I've seen a couple different methods, and I'm not sure I quite understand the difference, or at least the reason you would use one over the other...In the 1st method, you can just add the Loader object using the addChild() method:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
Placeholder_mc.addChild(myLoader);
This will apparently add myLoader to the display list once it has completely loaded.The 2nd method, you supposedly can add the Loader.content; however, it appears you can only do this once the content has completed loading, so you need to incorporate an event handler with the contentLoaderInfo object:
Code:
var myLoader:Loader = new Loader();
var myURLRequest:URLRequest = new URLRequest("ExternalFileA.swf");
myLoader.load(myURLRequest);
[code]....
What are the pros/cons of adding the entire Loader object, as opposed to the Loader.content and vice versa?

What I have is a function that occurs every second. Every time this function is called, it will add two movie clips from the library onto the screen. I am wondering if there will be a problem if my function keeps on continuously adding children to my scene?
Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;[code].............

where addChild comes from? Is it pre-built in or does it com from importing Flash.display. Sprite (and if it is from Flash.display.Sprite, does it mean it gets imported whenever you display *any* subpackage of Flash.display?)

I am trying to add and remove children from the stage using a string. the string takes the instance name from the button pressed and i want to use that string to add a child from my library and its giving me:
"TypeError: Error #1034: Type Coercion failed: cannot convert "Floor2" to flash.display.DisplayObject."
I realize i have to make the string into the actual object but not exactly sure how.
Code:
var rollstr:String = this.toString();
var Floor1 = new floor1();
var Floor2 = new floor2();

I am looking at an xml file, and creating a big list of visible buttons for each "flag" via addchild().
One of the subsets of each "flag" button in the xml is "Content"
I've been reading a lot on this but I'm just getting more and more confused. Can someone break down for me:
How to pass the xml Content to each addchilded button, so it can then pass that Content to a function when it's clicked.
The Content is a string, like "Flag40.swf" which is the file I want my function to load when I click the button. I have everything working except for getting each button to tell my function which .swf to load.

I had a previous old script working with AS2 and have tried to convert it as the new system requires AS3 .the below script :
function displayItems() {
var xPos = 0;
var yPos = 0;[code].....
This gives me the following for the bolded line
Scene 1, Layer 'as', Frame 1, Line 44 1067: Implicit coercion of a value of type String to an unrelated type flash.display:DisplayObject.
This line used to be addmovieclip which worked. I'm not sure how to edit this to suit the new addchild method.

Is there a way besides pasting frames inside a layer to add an element into a timeline? I'd like to replicate the addChild functionality from actionScript into JSFL. So basically, I'd like to add a bunch of movieClips instances into another movie clip, does anyone know how to do this in JSFL?

I have an array with names referencing movieclips, how do I add them so that I can control them in a function? I want to control each one seperately.
If I wish to control the .x value of say myArray[1][6][12] do I have to call them individualy as in:
myArray[1].x+=128
myArray[6].x+=194
myArray[12].x+=236
Or can I control say the X coordinates of a bunch of movieclips in one line of code?
Here is my code:
ActionScript Code:
var myArray:Array = new Array();
var star:mcStar;
//var xpo:Number = new Number (Math.ceil(Math.random()* 400));//ignore

I am working on an Augmented Reality project .. This is the code that is called when the marker makes contact with the webcam.
[Code]...
Every time I remove the marker and put it back in view .. this script is called and is causing the action to duplicate itself over and over each time the marker is present. How can I do some sort of check to see if this is already added so that it wont duplicate ?

I still don't fully understand the way Flash works. (or both) I've made this class, objWipeable. It has three properties
wipeContainer is a Sprite that has a mask attached to it. Any display object passed in via addChild is added to wipeContainer because I've overridden addChild.
wipe is a MovieClip animating a blackboard being wiped clean - it is wipeContainer's mask. hand is a MovieClip showing the hand doing the erasing. It should be ObjWipeable's only child.
If I create a new ObjWipeable and add something to it:

I've got 2 classes:
Main.as
ActionScript Code:
package {
import flash.display.Bitmap;
import flash.display.Sprite;
[Code]....
When I do this there are no errors, but the 'addChild' function is not working. if I put the addChild function in the Main.as then everything works just fine. So my question is: How can I Let the addChild function work from another class then the main class.

I've come across something strange. In the game I'm building I have hearts representing the lives which th player has. I add and remove them from stage with add/removechild command. But for some reason one or more of the hearts gets a different visual size then the rest. I've traced out the size and it all matches. They are all width 25 and height 30, just as they are programed to be in my class.
Edited with code added.
Code: Select allpublic class RetroGameClass extends MovieClip
{
/*!-----VARIABLER------!*/
var heart1:Heart = new Heart();

I am trying to use addChild on a current project I am working on, the only problem is that I have to add movieclips to the stage based on an array of movieclips given to me and a number (index).
At this point I am trying it like so:
Code:
var array:Array = new Array('Mc1', 'Mc2', 'MC3'); // etc.
var num:Number = 1;
addChild(array[num]);

I have two classes, Init (which is my Document class) and LoadXML which... er.. loads in some XML data.
Init calls the LoadXML and when it has completed a green backdrop is draw to the screen...
but...
Why do I need to put addChild in both classes before the green backdrop (a simple rectangle) will show up.
Init.as
Code:
package{
import flash.display.Sprite;
import flash.display.Stage;
[Code].....
the confusing thing is why I need the addChild twice, once in each class - otherwise the green box doesn't show, no matter which one I take it out of?
And if its twice is that two green boxes on top of each other being added to the stage? one at depth 0 and one at depth 1?

I want to dynamicly add 4 different Objects (Info1 - 4) to the Stage with one function. I have 4 different buttons (Logo1 - 4). When - for example - button 1 is clicked, I want to add Info1 to the stage; when button 2 is clicked, I want Info2 to replace Info1 at the same level (7). Somehow I cannot get the correct instance name to control Info1 - 4. I get a "NULL"
