ActionScript 2.0 :: Get Copy Of Object In Array NOT Reference?
Feb 6, 2007
In the code below, i create an object and stick it in an array, then I make a duplicate of that array. I loop though the duplicate and change the value of one of the props of the object in the duplicated array. Doing this however unintentionally changes the prop value of an object in the original array. I'm assuming that the objects in the duplicated array are mere references to the objects in the original array. Is this correct? And if so, how do i make unique copies of those objects in the original array, so that changes made to the objects in the new, duplicated array are exclusive to those objects?
I know that i could probably make a new object when duplicating the array, and then recreate each prop, assigning values from the original objects.. but this is a simplified example. The project im working on has many props for each object, so, id rather just make copies if at all possible.
Code:
var testObj:Object = new Object();
testObj.prop1 = "hello";
//
var testArr:Array = new Array();
[code].....

hey, I was wondering if there's any way to push a copy of an object onto an array without having to create a seperate variable for each object.
For example- in c, i'm used to doing something like having a 'temp' object- and then in a loop i would set the value of the objects members and push it on to the array (vector). If i try to do something like that in flash though, it stores a reference to that object in the array, so every time it changes every new element in the array changes to have the latest values of the temp object.
Without using as2.0 classes (i.e. just mx style) is there any way I can get the effect i'm trying to get here- just have one instance of an object that i can redefine in a loop and push a copy of it into the array so that i wouldn't have to declare a separate variable for each one which would defeat the purpose of the array.

I need a simple way to copy an object I use as an associative array. I use Flash, not Flex, so apparently copy() is not an option - or is it?

Code:

I'm having trouble with my code. I keep getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at Test_fla::MainTimeline/frame1()
I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true);
for(var i:uint=0; i < numParticles; i++){
var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250);
addChild(p);
particles.push(p);
} function onLoop(evt:Event):void {
//for(var i:uint=0; i < numParticles; i++){
//particles[i].gravitate(1,1);
//}}

Can anyone tell me why the following is taking 4 seconds for Flash to execute:
_moleHoles = new Array();
var countingMoleHoles:Boolean = true;
var holeCount:int = 0;
[Code].....
There are 9 object on the stage (but this number could go up or down, that is why I'm dynamically grabbing these this way). So in my test case, this loop runs 10 times.
I have narrowed it down to something to do with the following line:
if (this['moleHole' + holeCount])
Is using dynamic (array syntax) object lookup that much of a performance hit?

In actionscript 2 I was able to make indexed associative arrays. Ex:
var arr:Object = new Object();
arr[0] = {var1:"one", var2:"two"}
arr[1] = {var1:"a", var2:"b"}
In actionscript 3 I cant seem to do this.I get the error below.TypeError: Error #1009: Cannot access a property or method of a null object reference.

I found a really weird behavior when using deep copy for objects (ObjectUtil of Flex framework).Imagine we have a class B which extends class A. Class A has property body which is of type ByteArray.I create object b (instance of B). Then I make a deep copy object bCopy, BUT this bCopy object does not contain body property at all! All others properties (of scalar types) defined in Class A are copied properly.When I define property of type ByteArray directly in class B, then this property is copied properly..

I'm new to AS3, and can't figure out why this loop isn't behaving the way it "should."
[Code]...
How can I give each anonymous function a reference to each object represented by f, rather than a simple reference to f each time? Specifically, why is it that each copy of the anonymous function gets bound to a single reference to f? How (I should say why) exactly does AS3 differ from JavaScript in this regard?

I've been starting to create my own classes for a project and I've encountered an error that I don't know how to solve. This is for a Game class collection.
How do I create an object with ActionScript if I only know the name of it? I have a class that should add an object as a "grid" and place it accordingly, so if I have a Square box that I want to place by 4x4 on the screen it calculates it automatically. Well, that's the goal anyway.
I have a function in my Grid class, Add_Background that accepts an Object to be added as the grid background. I use a movieclip (don't know if I can use a graphic element).
I call the function myGrid.add_background("name_of_my_movieclip") or myGrid.add_background(new name_of_my_movieclip());
The first one I don't know how to use, I don't know how the syntax for creating an object this way (etc: grid[a][b] = new name_of_my_movieclip() doesn't work...) so there has to be some other kind of way on how to pass this to the function and that it knows what to do with it.
The other thing I've tried is passing the object to the function (new Grid_Background() etc) but I can't clone the object anyway I try it and the ActionScript reference site says there's an mx.utils.ObjectUtil that I can use for this, but I have no access to it that I know of (tried it).

I am trying to use .slice() to copy an Array of Loaders (each with a jpg loaded in it), as follows:
newArray = oldArray.slice();
and it works, but the problem is, any changes I apply to one Array applies to both, as though .slice() had just copied a pointer to the same Array, but I was specifically told that .slice() would not exhibit that pblm. Before I just go back to loading the same images twice, is there something special about Arrays of Loaders or something else I might be missing?

How does 1 save copy of an array in AS3 such that changing an element of the copy does not affect the original array? I have an array of Sprites. I tired using splice(0), concat and even copying the array element by element. But everytime I change a propertly in an element of the copy, the original array gets affected. Why does this happen?

I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG();
var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.

I'm having trouble making a copy of objects in AS3 instead of making references.
eg.
var mainMovie:MovieClip = new MovieClip();
var copyMovie:MovieClip = mainMovie;
copyMovie.x++;
I don't any calls on copyMovie to edit things on mainMovie. I was reading that I should try implement a clone method on the objects I want to copy. Surely there is an inbuilt way to do this for most objects.

I know there are a million and one posts about how to copy a MovieClip object, and I'm fully familiar with the method of[code]...
For this reason I can't use the original.constructor job as flash obviously thinks it's a straight MovieClip, so I just get an empty MovieClip. So far I've been getting by with creating a Bitmap, but in future these swfs will contain animations too.

I'm trying to figure out a way to clone / copy a dictionary object.
I came across some articles on cloning that offer this code.
This does not seem to work for dictionary objects. I think it only really works for basic objects.
Has anybody come across a way of cloning a dictionary before
Code:
function clone(source:Object):*

I'm trying to make a copy of an array filled with Canvas objects. I use this code:
arCopy = ObjectUtil.copy(myClass.myArray) as Array;
What I get is an array arCopy filled with Objects instead of Canvas. Each of these Objects has propersties suggesting that it was Canvas (like uid="Canvas333" or name="Canvas333"), but it's instance of Object class. I've been using ObjectUtil.copy() before but never seen such behaviour.

I am trying to store my Application.application.parameters to my local variables
For example: var myVar:Object = Application.application.parameters;
So here is the tricky part, is I do ObjectUtil.toString(myVar)
I can see all the values and properties. However if I do myVar.clientName or any other properties I always get null or undefined.
