ActionScript 2.0 :: How To Loop & Array Syntax
Sep 7, 2006
I've got this loop and can't get it to work. It won't read the trace so I know the array call in my function statement is wrong but I can't see it at the moment. What am I doing wrong here? The rollover works when I write it out repetitively for the four buttons.
var btnAction:Array = new Array (oneBut, twoBut, threeBut, fourBut);
for (var i=0; i<btnAction.length; i++) {
this.menuMC.btnAction[i].onRollOver = this.menuMC.btnAction[i].onDragOver = function() {
[code].....

I have an array like this:
Code:
var myData = new Array();
myData["name"] = "John";
myData["Age"] = 35;
What is the syntax to loop through and get the key and value? I have tried for each and for in but they just give me the value of "John" or "35", how can I get the key e.g. "Name" and "Age"?

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?

I've got a for loop and some fuctions working, but can't get one line of code to work. The red line below is what I'm having a hard time with. I'm calling a function called "moveit". If I insert moveit(x1, y1); then it works, and my movieclip is moved to the x and y positions that I specified for item #1. Though I want it to work for 10 items (I only have coordinates for two here, and will add the rest later).
I've searched my ActionScript book and just can't figure out what the syntax should be for calling that function.

what I'm trying to do is access the data of several movies clips, that are inside of several other movie clips: MC1.insideMC._visible=false (which works, but isn't dynamic) but dynamically with a FOR loop. I've tried: For(bullet=1; bullet<5; bullet++){ "MC"+bullet.insideMC1._visible=false (this does not work) } Does anyone know the dot notation or another way to do this?

I have a series of images loaded in via XML and assigned to "loady" movieclips. This code works fine:
Code:
_root.myMCL.loadClip(_root.myImages[0].attributes.url,_root.loady0);
_root.myMCL.loadClip(_root.myImages[1].attributes.url,_root.loady1);
_root.myMCL.loadClip(_root.myImages[2].attributes.url,_root.loady2);
_root.myMCL.loadClip(_root.myImages[3].attributes.url,_root.loady3);
[code]...
I want to replace this with a loop since I know the total amount of items (myImagesNo), but this isn't working:
Code:
for (i=0; i<_root.myImagesNo; i++) {
_root.myMCL.loadClip(_root.myImages[i].attributes.url,this["_root.loady" + i]);
}

_xml.group3..image[i]
_xml.group4..image[i]
_xml.group5..image[i]
Im trying to reference each object thus:
_xml.group[myVariable]..image[i]
But it doesnt work. What's the correct syntax?

I've got an array that looks like this, iterating through:
(languageArray[i].languageName); //e.g. "French"
(languageArray[i].languageCode); //e.g. "fre"
I'm trying to populate a fl.controls.ComboBox dataProvider with this array. What I want to do is set the labelfield, as shown in the documentation:
[Code]...
In other words I want the name to be displayed, and the 'data' to be the code, which will be called when I click on the item. But the labelField is not the same as "French". How do I create the two fields in the array such that I can designate the first as labelField and the second as data?

ok, I got this doubt wich is kinda making me wonder for a while. scenario:_I've got a movieclip with a bunch of buttons inside that invoke a function and send parameters to it.no sweat so far._those buttons are named with a specific word followed by "_btn". that word is the same as the one that goes in the parameter. for example:ode:gobbledigook_btn.onRelease = function() {_root.myFunction(gobbledigook)}question:I'd like to be this work with a for loop, so I don't have to repeat the code for every button. so this is what I did:
Code:
_root.wordsList = ["bafflegab", "esculent", "kakistocracy", "palimpsest", "quincux"]
for(i=0;i<_root.wordsList.length;i++){

I'm using addChild(new nmonster()) to populate an on stage MC from my Library.
Instead of specifying the Symbol, I want to add it using an Array reference, like addChild(new monsterArray[0]()). I've tried a number of variations, but AS3.0 is unforgiving.

I'm trying to load data from an external text file into an array. I created an array and am able to load the data into an array if I explicitly say something like
ActionScript Code:
array[0] = event.target.data.uid1_name;
I can then do a trace statement on array[0] and it will output the correct name from the file. My problem is I'm trying to iterate through the variable names in the text file in the file by using an index variable. This is the code I'm using after doing all the URLloader, URLRequest, and so forth stuff:
ActionScript Code:
for(var i = 0; i<20;i++){
fArray
= event.target.data.uid_name;
}
This produces a syntax error. I've tried several other syntax variations but haven't been able to figure it out. I've also tried the following:
fArray
= event.target.data["uid"+i+"_name"];
fArray = event.target.data.["uid"+i+"_name"];
fArray
= event.target.data."uid"+i+"_name";
All three of those also give me errors. For the first one the trace statement outputs "undefinded" instead of "Doug". For the second I get "syntax error. Expecting identifier before left bracket". And for the third I get "syntax error, expecting identifer before uid.":
syntax to iterate the number after uid(uid1_name, uid2_name, uid3_name, etc)?

Having a hard time trying to resolve this issue, done a bit a of digging but can't find what i'm after. I'm pretty new to AS3 but know that Eval() has gone and been replaced with [] syntax. However, i'm trying to access a dynamic path to a clip and it seems that the array syntax will not allow more than one variable in a path.

using action script...
stop();btn001_btn.addEventListener(MouseEvent.CLICK,showimage1);function showimage1(event:MouseEvent):void { gotoAndPlay(10);}btn002_btn.addEventListener(MouseEvent.CLICK,showimage2);function showimage2(event:MouseEvent):void { gotoAndPlay(20);}
however movie is playing without stopping to "Listen" for a Mouse CLICK. Images placed at frame 10 and 20 should appear only when CLICK'd.
This code is straight out of Classroom in a Book CS4.

I have this map I'm creating in Flash. You click on a state, then you can click on an icon to view a tooltip/popup of some information. What I was trying to do was instead of creating new functions and event listeners for every different icon is to use a for loop...but it's not going so well.[code]...

I've a container file which loads an array of SWFs. The code is as follows:
var request:URLRequest;
var loader:Loader= new Loader();
stage.addChild(loader);
var myMovies:Array=["../flash/movie1.swf","../flash/movie2.swf", "../flash/movie3.swf"];
var movieNum:int=0;
var mcExternal:MovieClip;
[Code] .....
This works fine - the array is loaded and plays through once... What changes are needed to get it to loop through the array.

how can i set an array by using a loop.. the array is contains by a data that i read from database.. so the length of carry depend of the length of data in my database..
i try to use

if you could run a loop in an array?
I'm having to make an array that has each value increase by a 10, like 10, 20, 30, etc. is there an easier way to put in those values without adding them 'manually'?
and I have another question that is related. For this same project, on the stage there will be a text box and the user will put in a number--how can that value be run through the array? like say I input the number 500, how does it find it in the array? is there a passed id, a listener and a broadcaster?

Is there a simple equivalent to what I used to do in AS2 to add a bunch of new objects to the stage and throw them into an array so they can easily be referenced? I'm finding this more difficult than it used to be.

mc_array = new Array();
for(i=0;i<5;i++){

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?
