ActionScript 3.0 :: Dynamically Generating Instance Names?
Sep 18, 2009
I am working on a project at work that will be a data driven, county-by-county map of the United States. We have received a FLA file with all of the counties (3000+ of them) demarcated and placed properly. In addition each county is a unique movieclip in the library, with a unique library name. However, the instances on the stage have no name at all. In order to reference an instance it has to have a unique name, but I do not want to have to go through and name them all by hand as this could take me weeks. The names they have in the library are meaningful numbers (FIPS codes) and if I could just name each instance with the name it has in the library (since there are only one of each library movie clip in the stage) that would be great.

I've worked out a way to get the proper instance name in stored in a variable (called listName), and I've got a SOUND_COMPLETE listener applied to my sound channel. What I need to happen is, when the function called by the SOUND_COMPLETE event fires, the object on the stage with the instance name that matches the string currently stored is affected.[code]...

Is it possible to add a textField dynamically but have different instance name each time this is created? In other words if I have a button that whenever its click it will add a textField to the stage and assigns a new instance each time this is added.
Code:
button.addEventListener(MouseEvent.CLICK, addField);
var inputWidth = 200;
var inputHeight = 20;

I have loaded an externally SWF (sonswf) file inside my movie (parentswf).
son.swf has 2 objects inside its library: Character (Base Class = "flash.display.Sprite", Class = "Character") CharacterHead (Base Class = "flash.display.Sprite", Class = "CharacterHead")
The "Character" object has inside 1 instance of "CharacterHead" and "CharacterHead" does not have a instance name asociated with it.
This is something like what i have got so far inside parent.swf :
ActionScript Code:
var ipAddress:String = "NNN.NNN.N.NNN" // not important
var loadedSwf:Array = ["THIS IS WHERE I CAN GET SONSWF", null]
var loader:Loader = new Loader();
[Code]....
So i need it to trace the class (not the Base Class that it extends) when instanciated from the parent.swf

Something like this but instead of textFieldName this would be different each time.

I am using attachMovie in a for(var i=1; i<50; i++) loop.Everything loads fine, but I am having difficulty referencing the dynamically created instance names.I don't want to reference individually ie movieclip1, movieclip2 etc.but more by movieclip[i].Basically - if movieclip instance 1 is rolled over I want to display image 1, and so on?

I am trying to use a for loop, to place 5 instances of the same movieclip on the stage. In the loop I used .name to give each movieclip a unique instance name. But when I try to reference one of those instance names in an event listener I get an error. Here is an example of what I am trying to do:
Quote:
var xPos:int = 120;
var yPos:int = 60;
for (var i:Number = 1; i<=5; i++) {
[Code].....
This code generates an error saying that the cStar2 property is undefined. In the example above, does the for loop create 5 copies of the movieclip starC_moov, and give them unique instance names cStar1, cStar2, cStar3, cStar4 and cStar5?

What I'm trying to do is dynamically assign instance names to movie clips placed on the stage based on their position on the stage. Say if one had an _x value of 1, i would want to assign that clip the instance name of "clip1" and if another had the _x value of 599, I would want to assign that clip the instance name of "clip599". Logically, I would think it would work like this (placed on each individual movie clip):

I started a thread about a reference to a symbol House, in the output window, which was: House_1. A lot of people said some useful things about that. All day I've been thinking about it, and I came to the conclusion that I don't understand things, at a very basic level.
Consider:I make a movieclip which I give the Symbol name Drawer. (I don't export it for AcitonScript.)On the stage I manually place two instances of this Symbol. The first one I give the Instance Name drawer (in the properties panel). The second one I leave nameless.Now if I trace the names of both these clips, by
trace(this.getChildAt(0).name);
trace(this.getChildAt(1).name);
the output window gives me
drawer
instance2
Now I know that the so-called "instance name" which I gave in the Properties Panel (drawer) is, in reality, a variable name which Flash gives my first instance behind the scenes. And instance2 is a name that Flash gives my second instance. What exactly the nature of that name is, I do not know.My point is: both names (drawer and instance2) are the .name property of these movieclips. Otherwise I could not have traced them through asking for the .name property, in the above. Yet only the first of these two can be manipulated:
drawer.x can be set;
instance2.x can (as we know) not be set.
But...why? What is the real difference between these two kinds of names? How can they both be the .name property of their underlying movieclip, yet be of such a different nature? What IS the nature of the instance2 name? If it's a String, how come the .name property of one movieclip can be a variable name, while the .name property of another (but identical) movieclip is a String?
I've searched every bit of web page on the net I could find. But it looks as if nobody addresses this issue. We all just work with it - but it makes no bloody sense. A name property = a name property, you'd think. Whether Flash set it or I set it should not make a difference. The x property of a clip, for example, does not change in nature according to who set it - me or Flash.So, again, just to emphasize the problem: how can a property (the name property) of a movieclip change in NATURE depending on who set it? After it's been set, shouldn't the name property of a clip be of exactly the same nature as the name property of another clip?

Our client has tasked to dynamically generate grids with different size boxes. The grid should not have defined edges, but each movieclip should have a certain defined border. I'm pretty new to AS3 still, but can handle pretty much everything besides this sort of giant math problem. Here's a simple layout of what I'm looking for on a much smaller scale: [URL].
I can almost emulate this, but sometimes my boxes will overlap, and that's a dealbreaker. If I start hitTesting it works up until I try it with 55+ movieclips, then I fear that the script could freeze. Here's the code that works, but may freeze at times. How can I optimize this so that stack overflow errors can't happen?
package {
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.utils.getDefinitionByName;
public class box_builder extends MovieClip {
private var _path:MovieClip;

I am generating movieClips dynamically using attachMovie and then using a setInterval to animate them. However, if I repeat the operation the second set of mcs move twice as fast, the third set three times as fast etc. I can't for the life of me work out why.

I have a grid 8 columns, 3 rows.I used instance names such as 1-1, 1-2, 2-1, 2-2, ect to easily identify each cell. I can call the movieclips within them without a problem by doing this["1-1"].gotoAndPlay(1); but how do I go about calling them when I can't use "this"? "1-1".gotoAndPlay(1); does not work.

In the first frame I have 60 buttons with each having a actionscript in it using the instance name "A1". What I need to know is how can I REPLACE the instance name from A1 to B1 in 60 buttons in my NEXT FREAME?
Is there an easy way to do it rather than typing one by one?? I used the "FIND AND REPLACE" option but it replaces A1 to B1 in both the frames. I need to alter the instance name only in the second frame. How can I do it?

I get the error "Access of undefined property menu_bar" when menu_bar is an instance name directly on the main timeline. I'm not sure how I would call it in the other class. It also isn't exported for actionscript is that the problem?
I have it imported to my document class as:
var mouseClicks:MouseClicks = new MouseClicks();
addChild(mouseClicks);
Then the class looks like this:

I know I've read something about this here before but I can't find it, so for Mr. Thicky here, I have dragged some buttons on my stage - each one is actually an instance of the same movieclip. In the IDE, I have given them instance names like 'myButton1', 'myButton2' etc. I've then grouped all these buttons together into a single container movieclip called 'buttonHolder'. Now, in my code, I am trying to retrieve the instance name of the button I have clicked on:

I have 100+ of the same movieclips on the stage at the same time, all positioned differently.i'm getting really tired of clicking on one of them, then clicking in the instance name box then typing "i65", then clicking on one of them, then clicking in the instance name box then typing "i66"...
is there anyway flash can fill this information in for you? or a plugin anyone's heard of? this isn't really an actionscript question, I'm not so fussed about selecting the different movieclips based on getChildAt or any of that stuff, I'd just really like a faster way of assigning instance names.

I have a 4x4 set of square buttons that I need to give instance names to. They will be named 'btn_1' thru 'btn_16'. Is there any shortcut to assigning the names or do I have to go through 16 times clicking on the button and clicking down to the 'instance name' text box?

I am working on making a photo flip animation between 5-7 photos but i have to duplicate this 70 different times. So what i have done is made a scene for each set of 5-7 photos, they are externally being pulled in through an AS3 script to prevent a large .swf file from happening with all those photos. The problem i am running into so that i cant seem to run a find and replace search to replace the instance name values.

iv got these buttons animated using the inbuilt tween function and am coding them like this:
function navOver(e:MouseEvent):void {
var page = MovieClip(e.currentTarget).buttonThumb;
var myTween16:Tween = new Tween(page, "y", Regular.easeOut,
0, -25, 0.35, true);
[code]....
MovieClip(e.currentTarget).instanceName returns undefined neather of which are the instance name.i cant hardcode the function because its used on lots of different mcs throughtout the flash file

I am trying to get the instance name that i gave to a dynamically created movieclip the movieclip was created using var zebra_mc:Zebra = new Zebra(); //creating a new instance of the zebra class The movieclip was then added to the stage using a for loop, as it was contained in an array. Each time a movieclip is added to the stage it is then added to another array (existingObjects) I then need to iterate through this array and pull out each objects names. I have tried using existingObjects[i].name, which returns "instance140" and existingObjects[i].toString, which returns functionFunction(){}, very useful. and existingObjects[i] which just returns the object.

I know its possible to hit test From something without an instance name if you have it in a seperate .as file. All you have to do is type in this.hitTest(InstanceName);
But, Is it possible to do a hit test from something without an instance name against something else that doesn't have an instance name?[code]...

I know you can store instance names in an array and call on the array values to reference the instance names in it.I was wondering if there is any way I can take an instance name, feed it directly into a function and use the name of the function variable/array/whatever to affect the object instance of whatever I name.
if it's an array of instance names, what is it actually an array of? Also, is there any way to hold and reference an instance name in a single value? sidenote: this doesnt have much to do with my question, but can arrays be fed directly into the header of a function?

I have a Flash CS4 FLA throwing the following error when I hit Ctrl+Enter to test the movie: WARNING: Multiple 3D objects on the same frame have the same instance name. 3D instance names must be unique. All but one of the instances will be renamed during export. On my layers, I can't see any duplicate instance names, and Flash doesn't give me ANY indication as to which names are causing the problem. I know it's to do with two layers making use of 3D Tween. When I hide them, the problem goes. I've even tried removing and replacing the Symbols. First of all, I have to have the objects on those layers Tween in 3D, and I have to give them instance names as I refer to them from ActionScript code.

I have a series of movieclips which I want to use as buttons.The instance names of the clips are as follows: "ms1", "ms2", "ms3" and so on...I want to put frame actions on these buttons, so that when the mouse rolls over on them, the button movie clip changes frame. I created an array to store instance names and then referred to it for actions, but the problem is that although my buttons do work, but when I roll over them, the button doesn't move to its next frame.
Here is my code:

I haven't seen much to explanation of this in any Flash documentation,but maybe someone knows more about this. Initially I was trying tofix a buggy application. The app is fixed now, but I'm still curious.I have an app that defines some object instances (buttons and movie clips)in various frames and on various levels of a timeline. For any object thatneeds to be manipulated by AS, I give it an instance name. However, there's no safeguard against giving several instances the samename. So, I experimented with giving two buttons, on differentlayers and different frames, the same instance name ("playbtn"). Then I defined an event handler:
playbtn.onRelease = function () {
gotoAndPlay(1);
}
