ActionScript 3.0 :: Access Child At Top Index?
Dec 13, 2011
I am adding movieclips (myBall) to the stage by the click of a button. There is a base class applied to myBall which allows it (and its children) to be dragged and dropped. Within the base class on mouse down, along with startDrag, the movieclip is being brought to the top index. I would like to be able to refer to this movieclip in my document class. The point of doing this would be to apply a function to the last clicked movieclip (finding what movieclip was last clicked would happen by applying the function to the movieclip (myBall) with the highest index).[code]...

I'm not too familiar with how I can use the getChildIndex() along with an if statement in a mouse_move event to make sure one image is always above the other or one is always on the bottom

I'm working on a project conversion from AS2 to AS3.
In AS2, I used a mainMenu file and loaded a Navigation file at _level 999 (very top). Then I loaded and unloaded different modules on _level 5.I also loaded and unloaded an external Glossary file on _level 95.Now in AS3 I am using AddChildAt(1) for the Naviation file and AddChildAt(.1) and removeChildAt(.1) for the module files. The Glossary file only seems to work at Child Index 1, so I'm guessing it pushes the Navigation file to a higher index. Is there a reference that explains the Index properties of the Child and why sometimes I get an error when I try to add a Child of Index 2 or higher?

I've got multiple images being loaded from an xml document and when they're created they add it to the stage and call a setIndex function to set it to 0. But when I try to the same object later on when they're called I get this compiler error:
I marked in bold the lines that relate. Out of the last two lines I marked bold I get this compiler error when I use the first one: 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.display:Sprite.
and this output error when from the last bold line: TypeError: Error #2007: Parameter child must be non-null.

I've seen some discussion on how to load a child swf using swfLoader and accessing it's variables but I am wondering if it is possible to do this without adding any code to the child swf.Either accessing public vars or listening for funciton calls would work fine

Im trying to build a class that moves around some movieclips on the stage, but it would never be that easy would it!
Code:
package {
import flash.display.MovieClip;
public class Rotation extends MovieClip {
[Code]...
So I waddled it down to the "stage.addChildAt(mcContainer[i], i);" bit and I've tried everything that I could think of, but nothing seems to work.
With this version of the code, I would get "The supplied index is out of bounds." error, I can change it to addChildAt etc, but that just gives me a different error.
I had this working when it was in a flash file, its converting it into a usable class thats bugging me. All the MovieClips in the array are being exported for Actionscript.

Here's what I'm trying to accomplish: I have as3 script that successfully displays an array of MovieClips, the MCs have variable xy positions, and in some cases they overlap each other. I have a function within the array that I can't quite figure out. Here's what I'd like the function to do: When the cursor rolls over a particular MC displayed by the array,I'd like that MC to be brought to the front of the others. This is my script:
var myArray:Array = new Array(); for(var i:int=0; i<8; i++) { myArray[i]= new myImage();addChild(myArray[i]);myArray[i].x = 180*i;myArray[i].y = 330;myArray[i].addEventListener(MouseEvent.ROLL_OVER , overlap);
function overlap (event:MouseEvent):void
{trace('function triggered on image ' + i);

I have 3 objects (mask_cat, mask_dog, mask_sea_monster)on the stage and I want the user to be able to move them independently with the ol' click and drag.[code]So far only the, sea_ monster moves. The odd thing is the sea_monster moves when I click on the dog or the cat also, but not if I click anywhere else.

I have 10 movie clips on the stage all of them are on the same layer and the alpha property at 0.5.
I want a single movie clip to randomly move to the top of the other at timed intervals. This movie clip alpha property will change to 1 while the other movie clip will remain at 0.5

I'm writing a game with Flash CS5/AS 3.0 that tries to simulate depth of field by drawing all the relevant Movie Clips based on their Y position in ascending order, i.e. things lower on the stage overlap things higher on the stage. A MovieClip with a Y position of 10 would therefore need to have a lower index compared to a MovieClip with a Y position of 20, so the second one gets drawn on top of the first.
I wrote a quick and dirty function just to test this. During the trace, I've noticed that the truck's index hits 0 when I go near the top of the stage, but if I go too far up it will completely disappear from the stage. Trace then starts generating this error:
ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.

I have a set of buttons which trigger menu panels to tween up from below the screen. I want these menu panels to be displayed behind the buttons (which are displayed on the button edge of the screen). So I add the menus to the parent container, then I add the buttons, so that the menus would be behind the buttons and getChildIndex(buttons) = 1 and getChildIndex(menus) = 0.
The menus are correctly displayed behind the buttons when I comment out the tween code. But when I implement the tweens and start the tween of the menus, they do their motion tween but are displayed in front of the buttons instead of behind; somehow their display object index order got screwed up.from the Menu class:
Code:
this.tweenIn = new Tween(this, "y", Regular.easeOut, stageHeight, stageHeight - this.height, 2, true);
this.tweenOut = new Tween(this, "y", Regular.easeOut, stageHeight - this.height, stageHeight, 2, true);[code].....

I would like to edit a cell by the row and column indexes so essentially do the following:
advDataGrid[2][3] = "Dogs"
so that I am setting the data grid row 2 and column 3 to Dogs. I cannot for the life of me figure out how to do this!
Side note: I need this because I am trying to allow the user to copy a section of an excel file to a section of an AdvancedDataGrid like Google Docs does. I am using this idea to do it: [URL]

Upon the stage of my flash movie, I have several symbols (movie clips) which I need to address dynamically using a loop. The symbols that I want to address all have instance names beginning with the string "lamp_", they then each have a different number concatenated on the end to distinguish between them (e.g. lamp_1, lamp_2, lamp_3.....).
The following noobish effort I have devised is totally useless, and I am hoping someone can show me how I might get this working[code]...

I'd really like to be able to make Flash's array access syntax 'wrap' over the array's bounds.
Lengthy explanation -
var array:Array = ['a','b','c','d','e','f'];
To keep things simple, the first index is 0, and its value is the first letter, 'a'. To get that value, we'd do this -
array[0]; // returns 'a'
As long as the index you're using to access the array is between 0 and array.length (6 in our example,) everything works fine - but if you use an index outside of those bounds, you're shut down.
array[-3];
array[9]; // both return 'undefined'
Sometimes that's a good thing - sometimes you expect that to happen, and you're fine with it. Other times, you find yourself wishing (or at least I find myself wishing) that it'd behave a bit more like this -
array[-3];
array[9]; // both return 'd'
(e.g. a photo gallery that jumps back to the beginning when you click 'next' on the last photo)There's a little chunk of code I use over and over for this sort of thing, but it's always to alter the index before passing it into the array:
var index = -3;
while(index < 0){index += array.length}
array[index % array.length]; // returns 'd'
... and that's fine, but what I really want to do is extend the Array object itself so that it'll automatically 'wrap' index values that go out of bounds.TL;DR - Is index-wrapping possible by extending Flash AS3's Array object?

I'm in a situation where I have a xml document which is going to be updated in the following way: The deepest child within the document which surrounds a certain x,y position (depending on it's x, y, width and height attributes) is going to get a new child element. If multiple childs exist with the same depth, the bottom one is updated.
My first step was to find this deepest child, this already caused problems, but I managed to solve this with the following recursion[code]...

So, for sending to individual streams we have to reference the connected netStream we want to send to in some way like this:
sendStream.peerStreams[0].send("MyFunction",param1,param2);
and I have to determine which peer I'm sending to by their ID such as "peerID1234"
I know that you can check the peerID of the stream by doing:
sendStream.peerStreams[0]["farID"]
how can I make my send stream function know to use the array index where the peerID is?
so basically it could be like:
sendStream.peerStreams[where peerStreams[]["farID"] == peerID].send("MyFunction",param1,param2);

i've made a simple example here to show you my problem. I have basically created a stage object ("box"), with the nested children, box->b->c. I have exported box for as, with class "box" and base class movieclip. Now i create 4 instances of my box class and add an eventlistener to the nested child c. When i later on try to remove the eventlisterner for myinstance.b.c i get: TypeError: Error #1010: term is undefined and has no properties.at DocumentClass/removeSomething(). Here is my code:

I am trying to add a child in a movie clip and perform basic operations on the child but I cannot get access to the child.
It loads the child to the movieclip "FLine1MC" but it says FLine1MC.ClipArt1 does not exist when I try to change the x location.
function AddArt1(evt:MouseEvent): void {
var ClipArt1Request:URLRequest = new URLRequest("images/mypic.gif");
var ClipArt1:Loader = new Loader();
ClipArt1.load(ClipArt1Request);
FLine1MC.addChild(ClipArt1);
FLine1MC.ClipArt1.x = 550;
}
Anybody know what's my error?
By that token, is there a way we can check the exact path of an object?

I am adding a movieclip in a class I will call class B that is added to a class I will call class A. In class B I am adding the movieclip like this:
var thumbHolder:MovieClip = new MovieClip();
thumbHolder.name = "thumb" + loadingCount;
MovieClip(root).slideMenuHolder_mc.slideMenu.thumbs_mc.addChild(thumbHolder);
trace("after: thumbHolder.name is: " + thumbHolder.name);
In class A, I can do something like this:
thumbs_mc.alpha = .3;
But if I try to do something like this, I get an error, even though the trace above traces out the names correctly. thumbs_mc.thumb1.alpha = .3;

I have a cloud named cloud2_mc and in its timeline i have a cloud layer, and an actions layer. I took the cloud and made it into a a Movie clip clip with an instance name of embeddedcloud_mc in this Movie clips timeline i have a 50 frame animation of the cloud breaking appart and disapating with a tween and i have a stop(); function on frame 1 of this layer.
What I want to happen is, when the cloud2_mc movie clip is clicked to play the animation of the cloud breaking appart. the cloud2_mc has a trajectory moving slowly accross the sceen continuously when the cloud2_mc reaches the side of the sceen it loops again. When the animation is clicked i would like it to continue across its path but, when the cloud2_mc reaches to left hand side of the screen i want the embeddedcloud_mc to reset its timeline and go back to its original state where the cloud has not broken appart.
My question is, how do I access an embedded movie clips timeline to tell it to play an animation on its timeline as well as, how do i make the same object restet its timeline to frame 1?
