ActionScript 3.0 :: How To Add Objects Into Arrays And Call By ID
Feb 3, 2010
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?

here is my script:
var mcArray:Array = [mc1,mc2,mc3];
for (var j:int = 0; j < hotSpot.length; j++)

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:
Code:
var Values:Object = new Object();
var Infos:Object = {
title:'something',

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.

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.

I want to arrange certain objects from a vector/array into a gird
Currently, I know how to do this during the creation of the objects.
Here's the grid function I've created:
function ArrangeInGrid(uiRow:uint, uiCol:uint, iOffsetX:int, iOffsetY:int):void
{
for(var i:uint = 0; i < uiRow; ++i)
{
[Code].....
Now I want to be able to apply the same logic of arranging objects in an array/vector in to a grid, how do I do it?
Or suggest a more efficient way to do so (if you have).
Notes:
I want it to be flexible in how many rows and columns the grid can have. The vector I'm using already has the cards in it. I can't just push the cards into the vector cuz of the way I manually created my cards.

can you create arrays of Bitmap and Sprite Objects? or Custom Objects?
if not, how would you typically create multiple Objects of the same type? just a loop with
var enemy:Sprite = new Sprite();
for(var count:int=0; count<10; count++)
{
enemy = new Sprite();
[Code].....
That way could be fine for many things, but theres other things I want to do.. such as, create an array of wav sounds.... and my program could pick and choose them, so they wouldnt need to load them on demand.. midi files too.

I've got an array of coins, which are called within the array coin1, coin2, coin3, coin4 etc. I'm trying to reference them to say if the character hits coin 2, then coin2 will disappear. Here's my array (so far):
ActionScript Code:
var coinArray:Array = [coin1, coin2]; //an array which contains all of the coins
And here's the script I'm working on:
ActionScript Code:
function coinCollect(evt:Event){
if (collisionTest (character, coin/*[n]*/){
var i:int = /*the number from coin[n]*/ - 1
remove coinArray[i]
}}
But I'm missing some major things, mainly how to reference which coin has been hit, and how to take the number from that coin and take 1 from it to reference it's correct position in the array? (the code in /* */ tags represents things I'm not sure on the code of).

so I have writing a function that returns objects on the stage and puts them into an array. and the function works fine until i call the function on more than one object name, meaning if im in the root class, and I call this function on object1 lets say it will add all the object one's from the stage, but if i call it on object2 it will throw an error, which makes some sense, i guess it means that it is not adding it to a unique array, but im not sure how to do that. would it be a good idea to maybe make a multidimensional array? if that is the case would it be too slow?

I have an Arrays that contains the names of MovieClips:
Code:
var MyMCs:Array = ["A","B","C","D","E"];
The actual MovieClips names are "MC_A", "MC_B", etc..., I use this method so I reuse the same Array for multiple tasks, I simply add what ever it's needed to the name to match the task at hand. On this case I add "MC_".
Then I have multiple Arrays, with the same names of the values of MyMCs. The values of each these Arrays are the names of buttons that are inside the movieclips of MyMCs:
Code:
var A:Array = ["RR","TT"];
var B:Array = ["YY","UU"];
etc...
I could add a listener to a button this way:
Code:
MC_A.YY.addEventListener(MouseEvent.CLICK, DoSomething)
My problem is that i want it to be done dynamically, using the Arrays values in a loop to add Listeners to the all buttons. The loop system is not a problem for me... my real problem is in the dynamic attribution itself.
Here is what I have:
Code:
//'i' and 'j' have previously been created
for(i=0; i<MyMCs.length; i++){
for(j=0; j<this[MyMCs[i]].length; j++){
[Code]....
I know that this is correct since I tried them separately and I can trace the proper values.
I know that my problem is in the "this" since I get an error message stating:
1084: Syntax error: expecting identifier before this.
I suppose it should state something else... I tryed with "root", "parent", "child", "MovieClip"... with no luck...

how can i have an array of strings but also with mc identifiers in the same array and have it know the difference between object and string? RIght now i've got this array of strings that goes to a textfield, and if i change it to
portfolioSection(["section 01", "section 02", {linkage: "linkage_id", x: 530, y: 280}, "section 04", "section 05"]);
this.attachMovie(portfolioSection[2].linkage)[/AS]
to try and attach an MC instead of text in a textfield i just get [object object] in the text field.

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.

does anyone know if it's possible to use variables to call objects from your library onto stage like this:I have an object in my library called Level01 as is it's linkage
Actionscript Code:
var MyMap:String = "Level01";addEventListener(Event.ENTER_FRAME,LoadMap);function LoadMap(event:Event) { var myLVL:MovieClip = new MyMap();// how do you use the variable

After having some trouble with object deletion, I ran a simple test:Created a simple class with a weak reference listener for Event.ENTER_FRAME.Added a trace("I Exist!") call to the listened function.Instantiated a single instance with one reference in the Document Class.his worked as expected - the SWF file did nothing but print "I Exist!" every frame to the console. (In debug mode, of course.)What I did next did not work as I expected:I set the only reference of the object to be set to null on a mouse event, but the messages from the event listener of of said object still appeared in the console after the mouse event was fired and the reference set to null - meaning the object still existed!Calling System.gc() in the document class IMMEDIATELY stopped the event listener from printing further messages and seemingly deleted the item.
From what I understand, calling System.gc() is discouraged, but as it seems from this simple test the garbage collector is a big FAIL.Am I doing something wrong here in trying to dispose of the object, or should I simply call System.gc() every time I want to get rid of an object..?

I'm trying to manipulate (in this particular case add eventListeners) objects (in this case some MovieClips) on the stage from a class that isn't the document class.
1120: Access of undefined property trans.
Now I know that it's probably a scope thing and I probably can't access stage objects directly from a non document class (as I'm doing in the code below) but I can't figure out how to access them properly.
Anyway, here's the deal:
I've got 3 dynamic text fields (called "NL", "FR" and "EN") on my stage in a movieclip called "trans". I'm trying to add eventlisteners in a second class to make them do something when clicked on.
Here's my document class:
package {
import flash.display.MovieClip;
// Import custom classes.
