ActionScript 3.0 :: Getting An Array's Index?
Jan 18, 2011
I have a game map made of tiles, each tile is stored in an array called _tiles.The very each tile has a "plantable" parameter, which determines whether or not something can be placed on it.Then i loop through the array and check the position of each its elements against the mosue cursor, so I know which tile am I hovering with my mouse.
And it works pretty good. The problem is that even though I know what is the position of the tile I'm having the cursor on, I still lack the knowledge of what index is that tile. I simply can't tell where exactly in the array is placed this tile. I just know its position. The reason why I want to know the index of it, is because it's the only way for me to set a proper flag, namely whether it's plantable or not. Here's the code:
ActionScript Code:
for(var j:int = 0; j < _tiles.length; j++)
{

So, for sending to individual streams we have to reference the connected netStream we want to send to in some way like this:
sendStream.peerStreams[0].send("MyFunction",param1,param2);
and I have to determine which peer I'm sending to by their ID such as "peerID1234"
I know that you can check the peerID of the stream by doing:
sendStream.peerStreams[0]["farID"]
how can I make my send stream function know to use the array index where the peerID is?
so basically it could be like:
sendStream.peerStreams[where peerStreams[]["farID"] == peerID].send("MyFunction",param1,param2);

I have used a method to shuffle a part of a Array, but i noticed that it does not work very well.When i run this method I sometimes get empty array values.So if you would try the example below and test it out some times you would get a right result but sometimes a wrong result.For example when i run this i get in my trace output:
a,b,c,d,g,,e,f (here after the g it goes wrong)
a,b,c,f,g,d,e (here it goes right)
a,b,c,d,,g,f,e (here it goes wrong)[code]...

Is there a way to get the index of an array?
For instance, if I have an array:
buttons = Array("abc","def","ghi");
If I wanted to get the index dynamically of the string "ghi", could I do that with a certain function or piece of code?

I thought that there was a way to be able to name array indexes. Like instead of myArray[0], it could be myArray["tileFour"]. I thought that instead of using index numbers one could use index words.

Is there a way I could specify the index of a array using this short code:[code]How would I go about giving a custom index name instead of it being myArray[0]? I could do it the long way like posted below, but I was wondering the there was a way to shorten this:[code]

Consider an array with x number of elements (of type Object) where some of the elements might be undefined.I use a for-each loop to access all the elements of the array that is not undefined (since it simply skips the undefined elements).But I also want the index of that particular element.The only option I can see is to use indexOf(). But it feels a bit like looking for water on the other side of the river so to speak.
When looping through long arrays each frame, is there a change indexOf() might slow it down? or does the for-each loop somehow know what index it's dealing with?

I am working with a set of external XML data, and putting it into arrays. I have set up images and text on a page using XML data, which, when clicked on, will populate a popup window with XML data from the same index. For some reason, when I trace the index of the array, it comes up as -1.
stop();
itemNameTops1_txt.text = nme_array[0];
itemPriceTops1_txt.text = price_array[0];

I have a tricky problem in that I have an array that has been populated with strings ("item1", "item2", etc). However, at a certain point I need to pull one randomly out of the group, via a random number function. The issue is I cannot reference the items in the array by a number, I get an error. So when I try to get myArray(5) it doesn't work.
How can I work around this so I can grab a random item in my string array?

I got a problem with processing an array in actionScript. I removed the last element of an array through array.pop(). After that I would like to put this removed display-object back to the beginning of the array: array.unshift(object). The object is now the first element of the array but it got still its old label (number of the last element). Therefor I can't update the position (graphically) of the display object. Is it possible to "reindex" the array?

var arr1:Array = new Array();
arr1.push(item1);
arr1.push(item2);
arr1.push(item3);
then arr1 and its elements get passed to other functions is there a way to know the index of an item in the array?
GetParentArrayIndex(item2) would give me 1;

I'm building a plugin and I'm using actionscript to save the selection of an object in an illustrator document and then reference it later.
var arrObj:Array=new Array();
arrObj.push(app.activeDocument.selection[0]);
If I select now the same object in the document and check if its in the array it returns a -1 for the index value.
var id:int=arrObj.indexOf(app.activeDocument.selection[0]);
trace (id); //-1
Why is the selection not considered the same object as in that of the array?

I have my grid-array in my flash game that has a set sized index in it, and through some code it sometimes checks outside of the Array index. Is there a way I can check to see if a index slot is undefined/existent
Gives me a TypeError #1010

if (Grid[ X + 1 ][ Y + 1 ] != null || Grid[ X + 1 ][ Y + 1 ] != undefined ) {

I have an MD array:
var fitb:Array = new Array("question1","question2",[["answer1","t1"],["answer2","t2"],["answer3","t3"],["answer1","t4"]]);
It's for a quiz program. Question1 is the first part of the sentence, the answers words that are shuffled and question2 is the last part. So basically they have to align parts of a sentence in the correct order.
Everything is groovy, but I can't figure out how to check if the words are in the correct order. The current [2][0][1] position is my test for embedding the answers, but when it's shuffled it seems to ruin everything.[code]...

I copied some code over to a similar function, which traces out the array index number using indexof(e.target).For some reason I'm getting the usual undefined property errors, but it is tracing other properties in the array using e.target?[code]

Consider an array with x number of elements (of type Object) where some of the elements might be undefined. I'd like to use a for-each loop to access all the elements of the array that is not undefined (since it simply skips the undefined elements). But, I also want the index of that particular element.
So I have two options:
1) Use array.indexOf(element).
2) Use traditional for loop, thus getting the index out of the iterator.
I'd rather not use option 2 since it contradicts the whole idea of not having to deal with undefined elements.

I am trying to trace an index number from an array.
I know this must be about as simple as it gets, but I just cant figure it out.
I know the contents of the array are all asighned a number begining with 0.
I need to find out the index number of a thumbnail when you click on it.
Code:
function whenThumbsLoad(event:Event):void{
var thisThumbsLink:String = clipPathList[ c ];
var thisThumbsTitle:String = clipTitleList[ c ];
[Code].....
I know I can trace the thisThumbsLink and get that, but all I need is it's index number. Also I trace(c); and I get how many there are, but I just don't know what to trace to find the index number.

i used a for loop to addChild of a class object(movieclip) to the stage and at the end line of for loop after addChild i push it into an array and i add eventlistener to it , such as
for (var i:Number = 0; i < 9; i++) {
.....
clip = new CLIP;
......
[Code]....
and if i want to get the array number which currently accessing how can i do that ? for example, i drag one of the mc class from the array which has already added eventlistener above.
how can i get the number of the array which im accessing ? evt.target..... etc ?

I've defined an array which stores the function name, like this:
var aresetButtonTop:Array = new Array(resetTop1,resetTop2,resetTop3,resetTop4,resetTop5);
Then I have a button named"btnresetTop" which when clicked will call one of the five functions stored in the above array(aresetButtonTop). The functions are called at run-time depending upon some conditions. I need to figure out how I can call those functions using the array index. I'm using the following code to call the function. The value of i has been already calculated.
btnresetTop.addEventListener(MouseEvent.CLICK, aresetButtonTop[i]);
After doing this I'm getting the following error when I click the button:
TypeError: Error #2007: Parameter listener must be non-null. at flash.events::EventDispatcher/addEventListener() at gallerytest_fla::MainTimeline/thumbTopClick()
Note: thumbTopClick() is a function inside which all these codes are written.
I need to find out whether it is posible in AS3 to call a function name using the array index or not.
