ActionScript 3.0 :: Looping With Associative Arrays/ Objects: #1034: Forced Conversion
Jul 16, 2011
I have had a long post somewhere on here and just wanted to start a specific post on just associative arrays. First of all I have an array which I don't know if it's an array or an associative array or an object or both. ie: I read that the below would be an object but works as an array too.
The problem is when I use this array as references to instantiate classes in a runtime shared library.I seem to be able to create the appropriate arrays and objects BUT I definately can't use/acess them properly. I massive confusion between movieclips and objects. I get a forced conversion error when I try to add objects to a movieclip . simply because I want to add the mc elements to the stage.

I was trying something out, and came across a little error. I wrote the following code to create an array and, using each value of that array, create an associative array for the values of xVelocity and yVelocity.[code]But I get an error from that as well. I think I understand basically why this doesn't work, but I'm wondering if, given the spirit of what I'm trying to do, you can think of a working alternative.

I have an associative array.
Actionscript Code:
myArray = {car:"Ford",type:"Mustang"},{car:"Chevy",type:"Camaro"});
Now if I wanted to add data to the indexes how would I do it?
For instance I now want to add years 1985,and 2000 to the index 0 and 1.

I'm trying to send an object to javascript that can have an arbitrary number of elements included, including associative arrays. If I create the following object:[code]The numeric indexes of the array will trace out, while the string based indexes will not. Does anyone have any idea why this might not be working? (Running CS4, I can't find the option to change my signature)

First I need to come up with a storage mechanism that looks something like this
x coord: 124 y coord 26 color: orange
x coord: 13 y coord 54 color: orange
x coord: 14 y coord 14 color: orange
x coord: 124 y coord 46 color: orange
x coord: 154 y coord 26 color: black
x coord: 12 y coord 21 color: orange
Secondly I need to know how to run a test to see if there is already an entry in that list that has the mouses current coordinates, and if it doesn't, it places a new entry with the mouses coordinates with the current color variable which will be a variable that flcikers back and forth between black and orange based on a timer that runs separately. I know that forEach will be involved and I know that what I am working with will be called an associative array.

I'm trying to use associative arrays to store my variables but am looking for a solution to change the value of array1[i] to array2[i]. Since it's an associative array, the only way I know how to loop through these kinds of arrays is by the following:
Code:
for(var i in array1) {
trace(array1[i];
}
What I would do when using indexed arrays to change the value of array1[i] to array2[i] would be something like this:
Code:
for(i=0; i<array1.length; i++) {
array1[i] = array2[i];
}
However, I can't see any way you can do this with associative arrays because they do not have a numbered index such that in a loop you could
say array1[i] = array2[i] .
So I'm looking for a way to do this with associative arrays.

I'm looking for the javascript way to an associative map/array/hash that's using objects as keys. A replacement to what you can do in ActionScript 3 with the flash.utils.Dictionary. I'm sure java and C# have something like it too.It'd work same as a normal generic Object based assoc[key] but instead of string-based properties you use whole objects as keys (it will match not on toString() like Object does but on unique instance). Very handy to decorate objects you don't own (by using the object as keys and your decorations as value).[code]Main point of issue is I need to match on object only (it's being used by some other process you're not to interfere with but we still need association). So no magic .__hash props or toString() overloading (if possible).

im trying to create a conversion utility that uses number input via calculator style buttons to generate conversion for the following distances:
-Miles to/from KM
-cm to/from mm
-binary to/from decimal
Now i was thinking of possibly having the options contained within an drop down and an input text field where the numbers are entered via the calculator buttons. The only thing im struggling with is how to perform the actual calculations on the different formats. Has anyone had to do anything similar in the past? Ive only found currency conversion examples and not sure how to apply that to these conversions.

NOTE: The following text is my problem and observations, if you afraid to read it all, my problem is easily guessable within the code go ahead and crack at it without my explanation :-p I'm having some trouble with using hitTest(); with movieclips within arrays. I wanted to build a function that checks the hitTest of Movieclips in arrays because the array is dynamic and it would run more efficient and faster this way.
As you may notice it doesn't check just the movieClip in the array, but a movieclip 2 scopes within it. I feel that this is my problem. I noticed in my debugger that that mc doesn't show up, but i put an onLoad event on it to trace its existence when loaded and it shows up fine. I wonder what I'm doing wrong.

I created multiple classes for a platforming game in AS3 and when i am making the levels i simply drag the objects of a certain class to the stage from the library. My problem is that i am unable loop through all of the objects of class type wall from another class of players.(so that i can make every player created not go through every wall created)
Like: for(i=0 i<numberofwalls i++){
do sumthing with wallobject(i)
}
Are there any functions that can return the number of walls dragged to the screen and one that lets me access each individual wall dragged to the screen?

I want to put together an array of values that I can call by an ID I set myself, for example I want to be able to call "title" from the id "123", I tried this with Arrays but they don't seem to work the same way in AS3 as they do in PHP (the language I work with normally).
The following is what I am trying to achieve:

I'd like to know how to compare one array to another array with objects.
For example:
Array1 = [one, blue, car];
// there will always be only one entry in this array - no Array1[1], no Array1[2], etc.
Array2 = [product.number, product.color, product.type, product.cost, product.qty];
The actual content in Array2 would be something like this:
Array2[0] = [three, green, boat, 100, 5];
Array2[1] = [two, blue, truck, 200, 3];
Array2[2] = [one, red, car, 50, 20];
...and so on, up to about 60.
I'm trying to figure out to go through all of Array2 to determine if there's a match to Array1. Since none of the entries in Array2 are the same, there will always be one match.In this instance, I want to match array1 with product.number, product.color, and product.type. My example has them as the first 3 criteria, though that may not always be the case.
Something along the lines of this:
Code:
function findMatch () {
for(i = 0; i < Array2.length; i++) {
if(all 3 Array1 items equals items in Array2[i]) {
[code]...
Background: I've a combobox search that allows a user to select from drop-downs. After a user selects items from all 3 drop-downs, they click a submit button, and there's a check to see if the criteria in the drop-downs matches anything in the Array2 (which it should, if you can select it, then it's in the array).
After that, the matched information is used to populate a movieclip. There's actually about 20 pieces of information associated with each product. However, I only need to match 3 of them.I've searched and found comparisons for arrays. But I don't see how they'd apply to my issue as I'm using objects and there are more items in array2 than in array1. Of course, they may apply, and I'm just not understanding how. I could create a 3rd array and move only the items needed for a match from the array2 to it. Then I could do a straight comparison between array1 and array3.

Basically what I'm looking to do is hitTest bullets inside an array (spawn via addChild -> pushed into an array) with another array containing ships (spawn via addChild -> pushed into an array as well).At the moment I have:
function moveEnemyLarge():void{
var target2:EnemyLarge;
for(var i2:int=0;i2<enemyShipArray.length;i2++){
[code]....
.. and a near identical function for the bullets (using variables: i, target).What is the easiest way for me to hitTest the objects within my bullet array with the objects in my ship array. Putting "target" in the PLACEHOLDER slot doesn't work, and from what I've seen some people will shove the one for() inside of the other.

I have a loop, it goes through and works fine. I can trace out my variables and all is hunky dory, for example "trace(title);" displays the variable title, as expected, there is also the variables "something" and "everything" and a unique ID: id. Now I want to put these variables into an array, so the values can be called via the ID. For example (I'm a PHP programmer normally) in PHP I'd do the following:
Code:
$array[$id]["title"] = $title;
And to display it I would do
Code:
echo $array[$id]["title"];
For each part of the loop I want to add the "title", "something" and "everything" into the array so I can call them by "id". I think I'm doing it wrong though, should I be using objects? If so, how?

What i have is 2 arrays, where one is "correct" - set by the computer. The player then makes his array and when its done i want to compare them to see that they match up. The array is in theory able to go infinite (its a memory game), and i thought this would work.
The arrays can only contain the numbers 1,2,3 or 4. which is added like this
Code:
player.push(2);
Code:
if(player.length == siren.length)
{
if((player[n] + siren[n]) /2 == siren[n])
[Code]......
What happens with my code, is it goes to lose each time. How can i compare the object at spot 1 in each array, then 2 in each array, etc?

How can I use arrays and some how display my objects accordingly based on my code below?
What I have here are three buttons that when clicked a new clip is added to the stage with a predefined position which means that when button1 is clicked the MovieClip will be added at the very top and when button2 is clicked the MovieClip will be added at second and when button3 is clicked the clip will be added at the very bottom, but what I would like to do is to be able to dynamically position these objects based on how many clips exist, in other words if button3 is clicked first, I want the clip to be positioned at the very top and if later button1 is clicked the clip is positioned
Accordantly (at second place). I know this may be simple, in fact I could probably use a few IF statements but I know the code would look ugly (yes, even more) and I may have add more buttons later. What I would be awesome is to some-how use arrays or something that makes more sense to hold the MovieClips and then display them accordingly.
ActionScript Code:
button1.addEventListener(MouseEvent.CLICK, addItem1, false,0,true);
button2.addEventListener(MouseEvent.CLICK, addItem2, false,0,true);
button3.addEventListener(MouseEvent.CLICK, addItem3, false,0,true);

I've got four arrays which I want to use to create objects on the stage.
The first one is what the Object Class is called.
The second one is what I want the instance name to be.
The third and fourth relate to the x and y co-ordinates respectively.
ActionScript Code:
var objectName:Array = [Background, Frame, Up, Down, SideBar, Yellow, Green, Pink, Blue, Titles,
TimeBar, TimeBarSlider, Stop, Play, Pause, ThumbnailOutline, Thumbnail];
var instanceName:Array = [bg, frame, up, down, sideBar, yellow, green, pink, blue, titles,
TimeBar, timeBarSlider, stopBtn, playBtn, PauseBtn, thumbnailOutline, thumbnail];
[Code] .....
The "i" would relate to the parameters for the same object. So, if i = 0, then the Object Class Name would be: 'Background', the instance name would be 'bg', the x position would be '0', and the y position would '0'. What code would I need in the for loop to create this?

I am trying to make a to-do list application. I would like it to save each time I close. So I researched shared objects, and somehow cannot get it to work. I hold all my "items" in an array, then copy that array to a shared object. Here is the code used to copy the array: At the top. I put the array in a Global class, just ignore the GlobalVars.vars. junk. It's not really necessary, but it definitely works everywhere. ListItem is a class I made that works fine by itself.
Code:
var listCookie:SharedObject;
listCookie=SharedObject.getLocal("lkjasdf");
if(!listCookie.data.itemArray) {
listCookie.data.itemArray=new Array();
} for(var i in listCookie.data.itemArray)
[Code] .....
When this function is called, it equates the two arrays fine. I trace them both afterwards, and they have the same items in there. But when I close the .swf and reopen it, the saved array is full of undefined references. It has the same length, just nullifies everything it was supposed to have.
