ActionScript 2.0 :: Variable Object Referencing
Jun 14, 2007
I am in no way very knowledgable with ActionScript, so this might be very simple and I am looking in all of the wrong places... but basically here is my issue: Instead of accessing an objects attributes like this, _level0.thumbnails.thumbnail0._width = 500; I want to be able to access it with _level0.thumbnails. (this.id) ._width = 500; where as (this.id) is a variable that could be equal to "thumbnail0" or "thumbnail99" depending on which object gets clicked. I have everything working to if I hardcode thumbnail0 it works fine, and this.id does get set to whatever thumbnail I click's "thumbnail" + ID

I'm trying to set something up that will print a bunch of boxes on a grid in a certain pattern, and set things up so that a path can be determined from the start to the end. Each grid square is a MovieClip with an instance name x0y0, x1y0, etc. for each coordinate of the grid. I want to set a variable in my grid square class to 1 or 0, depending on whether or not a box is in that square. So I have this code:
for(var j=0; j < row1.length; j++)
{
for(var i=0; i <= row1[j]; i++)

I have a simple function that dynamically creates text fields. My text field name is referenced by var thisTextField. Problem is, when I try to do things with my text field, actionscript shoots back an error as such: There is no property with the name 'text'. How am I supposed to apply properties to my object if my objects name is a variable?
Code:
function showProducts() {
var products:Number = 0;
var thisTextField:String = "product" + products + "_txt";
for (var itemID in _global.rtsData[_global.rtsPos]["products"]) {

how to reference a variable when adding a new Movieclip?
Currently I am using this method:
Code:
var myVariable:String = "one"

fairly simple question (with a long explaination). I have an array, created from the results of another array and it's position in that array. There are actually multiple arrays It can be created from.
Eg.
Array1: clientName1, clientName2, etc.
Array2: clientType1, clientType2, etc.
Second Array: [clientName1,0], [clientName2,1] OR [clientType1,0] etc.
[Code]...
My issue is, I would like to be able to dynamically adjust the array that it is generating from. This would mean changing the bold bit of the code above. I have tried declaring a variable (type = names+"[i]") and using it in the linkArray declaration, however it will not see this as an array reference, only as a variable. What I want to know is, how do I reference the name of the original array as a variable so I can update it dynamically?

I have been using this line of code to fade in a movie clip:
new Tween(background_mc, "_alpha", None.easeNone, 0, 100, .5, true);
Now, I want to accomplish the same thing, only this time by using an element from an array (bg_array[currentSlideNumber]) that stores the instance name "background_mc"
I've tried the following, but it doesn't work:
new Tween(bg_array[currentSlideNumber], "_alpha", None.easeNone, 0, 100, .5, true);

This is a problem I thought I understood and was addressed in a previous thread [URL] but I have a new situation where the old solution isn't working.I have 3 instances on a "nested" movie clip. Their instance names are: b1, b2, and b3. When I trace these movieclips from the main timeline, I get:
trace(b1); // result = _level0.slide_mc.newMC.b1
trace(b2); // result = _level0.slide_mc.newMC.b2
trace(b2); // result = _level0.slide_mc.newMC.b3
From the main timeline, I want to fade up these movieclips using tween, but I need to do this by building the instance name in a variable:
var myInstance:String = "slide_mc.newMC.b"+ instanceNumber //(instanceNumber is equal to 1, 2, or 3)
Now, I thought using the variable in this manner would work:
new Tween (this[myInstance], "_alpha", None.easeNone, 0, 100, .5, true);
...but it doesn't.
I've checked trying to use the actual movie clip instance:
new Tween (this.slide_mc.newMC.b1, "_alpha", None.easeNone, 0, 100, .5, true);
...and it works fine.

I've got my variables set out in a layer on the main stage. I've also got a MovieClip which I want to write some code within but reference a variable in the main frame. I tried just referencing the variable name but it didn't find it. I then tried root.variable name but I'm now getting this error message:
ActionScript Code:

I finally got the variable referencing between classes and custom event problems sorted out. Now I got a question regarding the Error #2044 and Error #2035. The error reads like this:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I've put all the swf in the same directory, so I don't think that is the problem. Could it be that my XML file is in another directory that's causing the problem? I also heard having quotes in the URL in the XML file could also be problematic. Is that true? Here are my AS and my XML file.

I'm trying to reference an instance through the use of a variable in my call to a prototype. The variable is myVar and contains the instance name to which I want to apply the resizeTo prototype. My syntax is incorrect.
Code:
on(release){
//disregard this line
this.swapDepths(this._parent.getNextHighestDepth());
//this is calling a prototype named resizeTo
this.resizeTo(150, -100, -100);
//Setting instance name of another movie
myVar = "green";
//Trying to drop that instance name into my next prototype call
this._parent.myVar.resizeTo(100, _parent.old_X, _parent.old_Y);

How do you reference and already existing object in as3? My below program draws 2 circles and a line to connect the two. The circles and the line are all individual objects. The line (connector class) has a function called update that should redraw the line between the two circles. It has two variables which I want to be the references to the two circles. The circles (coolcircle class) has a variable which I want to be the reference to the connector. It doesn't seem like my update() function is getting called.

Is there a way to reference multiple movieclips using a single variable name? For example,I'm making a side-scrolling game, and there's going to be many platforms, and I have some code that tells the player not to fall through these platforms, but I don't want to copy and paste the same "platform" code every time I add a new platform.

How would I go about refferencing a variable and then turning it into a string (if that is the correct terminology). e.g:

I need the result of variable something to end up inside the speech marks without loosing its obvious refference to the variable.

I am trying to load an image in to a dynamically created movieclip, which is:
_root.mySlider."+stripX2(band[i][0])+i
but I can't seem to reference it. I can load the movie into _root.mySlider, but if I add the dynamic element (stripX2(band[i][0])+i) without quotes it it doesn't load. If I load with quotes i.e.
"_root.mySlider."+stripX2(band[i][0])+i
flash doesn't allow strings in movieClip variables.The code I'm using is belowm, it's the second to last line thats causing the problem:
var loadListener:Object = new Object();
loadListener.onLoadComplete = function(target_mc:MovieClip):Void {
trace(">> target_mc._width: "+target_mc._width);[code]......

I have an object present in frame 3 of the main timeline. When the object was present in frame 1 i could access it from an as3 code file. But when I am keeping the object in frame 3 of the timeline (Please note that the previous frames for that layer is blank). I am getting a null value for the object. if I try to use trace the object.Logically if I am in frame 3 i should be able to access it.

I need to know how to call or reference (not sure of the terminology) an object by way of a string. What I'm trying to do is create a loop that will add event listeners to objects named "portfolio1" through "portfolio15", and use a function.[code]If I could just reference these fricken objects through a string and an integer, I could set up a small loop like this to make the button "portfolio1" bring up a big jpeg of "bigportfolio_1", and "portfolio2" bring up a big jpeg of "bigportfolio_2", ext. While yes, I could just go through them all and set up event listeners to each one individually, but its REALLY inefficient. Also, I am still working on more advanced actions (like scrolling through the portfolio pics chronologically) that absolutely requires a different reference method.

I have my main flash, named "front page". Inside of it, I have 2 movie objects that have a time line, one named "About Us", and another named "Button Group". Inside of "Button Group," I've made a drop down menu that can go to a frame on the main page (in "front page") using the _root command. I was wondering if I could go from the front page into the other movie object ("About Us") by going through the main page.
Tl;dr, I'd like to know how to go to the parent of a movie clip and into another movie clip to modify where the time line is.

I have a fairy sizable class, a`nd an mx:Application that will periodically instantiate a new object of this class, which results in member functions of the class being assigned as event listeners to the application, and also other member display objects of the class being added as children to the application. When the application creates a new object of this class the old object is destroyed: to accomplish this, removeEventListener and removeChild are called on various members of the old object (to decouple them from the parent application) and then the final reference to the old object is set to null, and then finally the well known localConnection hack is called to force FP to actually free the memory.
And the thing is, the above destruction procedure always works to deallocate an object - except for the very first object allocated. it has proved impossible thus far to release the memory of the first such object created, or find out what is preventing it (i.e. find out what is still referencing it). So my question is - is there any useful utility that will tell you what is still referencing an object and keeping it from being garbage collected. Someone implied to me that the flex profiler would do this (which I do not have access to) but another 3rd party profiler I found for flex would not do this (i.e. tell you what is referencing an object and keeping it from being deleted.)

referencing instances of an object in AS3
I want to be able to build a navigation and reference each navigation item separately changing each instances properties depending on rollover actions etc.
I would have thought that once the name is assigned through the for loop that would stick, eg. the following code would create 3 vars called navItem, each with the name 0, 1, 2. But it seems if I trace the name outside of the for loop each is called 2. I think Im misunderstanding something really simple!
public function buildNav():void {
for (var i=0; i <itemNum; i++){
var navItem:NavItem = new NavItem ();

I've got a button which is called "playBtn", within this i have a MC called "btnlarge", If i remove the .btnlarge from the below code, then the "playBtn" is coloured correctly in my player,
Code:
var sColor:ColorTransform = player.playBtn.btnlarge.transform.colorTransform;
sColor.color = scolour;
player.playBtn.btnlarge.transform.colorTransform = sColor;
however with it in.. i'm obviously wanting the btnlarge MC to be coloured, but this isn't happening and its throwing me this error:
ReferenceError: Error #1069: Property btnlarge not found on flash.display.SimpleButton and there is no default value. at f4:layer/skinCompleteEvent()
Is there something really obvious i'm doing wrong? I've tried changing the "playBtn" into a MC and all kinds of things, but nothing seems to work, i can't seem to reference anything within another object.

I have a several objects nested within an array. I'm trying to reference a property of one specific object (intel).
function eventGenerator():void
{
var randomArea:Number;
randomArea = Math.ceil(Math.random()*5);
[Code].....
ainPlace names is the array's name. The random area variable contains the co ordinate on the array for the object. Each object on the array has a property called intel. The idea is I want to able to store the value of intel in a number and use in an equation. I would also like to be able to adjust the number. the trace function here returns an error saying it is undefined so eventArea.intel for some reason isn't referencing the intel property of the object.

I'm trying to:Jump from frame 1 to a frame later in the main timeline Reference an object that exists on the stage in that frame, but not in frame 1
Like so:
ActionScript Code:
function endGame():void {
gotoAndPlay("gameOver");
scoreField.visible = false;
}
A movieclip with the instance name 'scorefield' exists in the "gameOver" frame, yet for some reason, I just get a "Cannot access a property or method of a null object reference." This code is all within a function. By the time the reference to scoreField is executed, the timeline is at the right frame.
