ActionScript 3.0 :: Get Child Properties From Stage?
Nov 14, 2009
I have some code that adds a child using addChild(dragsquare); dragsquare is what I used as the class for a movieclip, mcsquare.
Everytime a child is added to the stage, it is called: ObjectX The "X" increments everytime a new object is added using ++objNum.
E.g:
Object1
Object2
Object3
etc...
When the child is added to the stage, it can be dragged, resized, rotated, etc...
I have used this code so when someone clicks the "save" button it loops through all objects on stage (increasing the last number by 1 to get the next object) and finding their properties. Here is the code I have used.
ActionScript Code:
Code:
save.addEventListener(MouseEvent.MOUSE_UP, saveObjects);
function saveObjects(event:MouseEvent):void {
for (var i:uint=0; i<numChildren-23; i++) {
[Code]....
23 children already exist on stage so I have to minus that number to get whatever is added on stage by the user.
However, scaleX is getting the childs ORIGINAL properties and not its current stage properties (where it has been resized, rotated etc..) and only returns a 1 for scaleX. How would I make it track the properties it has on stage?

Basically, I have a menu created using XML. Each menu item has a fill that fades in and out as the user scrolls over them. What I want to happen is that when an item is clicked, it stays highlighted. The problem comes when I click on the second item. I can't get the first item to "unselect."Here is the menu code and functions.
Code:
var menuHolder:MovieClip = new MovieClip();
menuHolder.x = myMask.x;

I have a holder movieclip on screen, then I create a loader, load an external SWF into the loader and addChild to my holder:
var bgloader1:Loader = new Loader(); [code].....
This all works. Now if I want to come back later on and alter the alpha or position I get an error:
//Neither of these work: MyHolder1.bgloader1.alpha=0; MyHolder1.bgloader1.content.alpha=0;

I have created a loop to instantiate tiles on a board. In the following example, "Gametiles" is an array containing objects of class "Tile" which is a class that extends MovieClip. "Game" is a MC that I added to the stage in the flash developing environment.[code]This method is a bit cumbersome though. I really don't want to have to create a var and call getChildByName every time I want to interact with these properties or methods. How can I set up these children so that I can access them directly without the extra steps?

Is there a way for the child of a movieclip object to not inherit the paren'ts properties? Because I scaled down the parent movieclip height and width and I'm loading external images into the parent movieclip and images are also scaled as well so I'm wondering if there is a way for it not to inherit the properties but remain inside the parent?

My player movie clip has a smaller movieclip within it. Because the smaller movieclip is not within the parent clip it changes the x,y,width,and height value of the player movieclip and throwing everything off! To adjust I have to add (-2ndmovieclip.height) to everything i want to do. This is sloppy and I don't like it. Is there a better way to have a child within a movieclip without it affecting the parents properties? i want the parent to keep its original x,y,width,and height properties but the child keeps adding to them!

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?

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).

If I have a textfield instanciated from the document class with a base .string set as for example "4444" and BEFORE adding it to stage, I change the .string value to say "1234", when I test the swf, I can see the 4444 for a very short time changing for the 1234.I didn't change the value after adding to stage so I don't get why the display number is changed after being added to display.How to force it to add to stage (display itself) only once the initial changes to his properties are done?

i can set the stage's background color, etc., using a SWF metadata tag:
[SWF(width="1024", height="600", frameRate="60", backgroundColor="#000000")]
or if i'm using Flash Professional, i can simply set these properties for the document in the UI.
while the Stage class offers the ability to set a frameRate and override width and height thru properties in actionscript, why is it not possible to set the background color of the stage the same way?
Stage doesn't have a property (public or otherwise) for background color. can anyone explain why that is? it seems strange to me but i'm assuming there is a good reason rather than this simply being a oversight.

I have an object on my stage, called obj.I also have a class called "Physics" which contains a bunch of methods for physics, such as inertia, gravity, and bouncing off walls. In order to do some of these,I need access to the stage.stageWidth and stageHeight properties.My code is as follows:
public function wallBounce(obj)
{
this.stageRef = stageRef[code]...
This is supposed to check if the object's x value is greater than the stageWidth or less than 0. When I run this code it says:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am a semi-newbie programmer who is completely self-taught and have no clue what is causing this. I spent a bit googling it, and I think it has something to do with scopes,.

I am using this code to iterate through the contents of a movieclip which contains instances of "alien2" - my alien. I have each alien in a movieclip called squadron1. They all have their own layer and follow a motion path to recreate the attack sequence in Galaga. I can add action script to them by right clicking on them, but when I do this test below I can't call any MovieClip methods on them. It is my intention to add a function to each one via code to make it detect bullets, look for the player etc, but at the moment all I can do is add the code to each one individually on the stage.
Code:
var target;
for(var item in _root){
if(_root[item] instanceof MovieClip ){
target = _root[item];

I am trying to access a property that belongs to the stage, from a class. For example, let's say I add a textfield with an instance name of "magic_txt" on the stage. In the Document Class, I am able to access magic_txt and update the field like so:
magic_txt.text = "Magic Text"
However, since I would like to work in classes, I am having a difficult time figuring out how to access the property "magic_txt.text" from a class. I know I need a reference, but I am unsure how to set this reference.
I am coming from a strong background in Visual Basic, and in Visual Basic, the way to access a form property is to call the form name (dot) object. In actionscript, it doesn't seem to be as simple.

is there a way to override a MovieClip's parent and stage properties? In a custom class extending the MovieClip class we can override the get parent() and get stage() methods. But is there a way to do it to existing MovieClip?
I mean I have an external swf content (loaded) and assigned to a movieClip. But now, how can I assign the loaded MovieClip to my custom class, so that it "doesn't see" the parent and stage properties?
Or can I override functions of existing classes? Sth like:
override public function myMovieClip["get parent"]():DisplayObjectContainer
{
...
}
I just need to prevent a loaded MovieClip from having access to the main movie's stage.

I have made a very simple swf in which I have a MovieClip which I have rotated on the stage. When I try to access this rotationX and rotationY properties of this clip using the constructor of the class assigned to this MovieClip they are coming back as 0 even though they shouldn't be. If I put an on rollover event of the MovieClip and trace out these properties here I get the correct values.
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
[Code].....
I also get the correct values when I read the values from the stage timeline.
trace ("TEST "+testMC.rotationX+" "+testMC.rotationY); //returns correct value
Is there a specific event I need to be waiting for which will tell me when the 3d properties are available via ActionScript?

1) In my program, I am wanting to create a function that would take in the height and width of a loader object, compare them to the stage dimensions, and then scale the object in question before it is added to the display list. However, I have several different types of classes that I want to make use of this functionality. So what would be better, to create a NEW class that would have to be created each time a resize needed to occur, and is imported by all needed classes, or just have a function within each already existing object and copy that function to every class's scope that needs it? Would this be resolved by placing the function in question inside of the default package?
2) When accessing stage properties, are they a global or a relative scope? i.e.[code]would those two statements produce the same value regardless of whether they were in the default package or inside of 1300 classes? Or is the stage scope relative to some degree?
