Looping Through Array Of Variables?
Jan 27, 2010
Why doesn't AS2 interpret these variable as it steps through? Everything works if I write it out longhand and do not use a loop, but if I try to condense things by using an array, variables such as _root.myTargets[i]._x are not interpreted properly.
Code:
myTargets = new Array('shoot','shoot2');
for (var i:Number=0; i<myTargets.length; i++) {
if ((_root._xmouse > (_root.myTargets[i]._x - 30)) and
(_root._xmouse < (_root.myTargets[i]._x + 50)) and

I want to do a for loop that grabs values from different variables. This function works nicely without the eval() statement (using the commented line below it) but not with it.
function saveData ()

What's the difference between looping through an array or using array.every() to assign a callback to each array element?

I'm using LoadVars (results_lv below) to load variables from an ASP page, returned as follows: option1=4&option2=5&option3=32&option4=... etc. etc.
There are a different number of "options" returned each time, depending on the query sent to the script. I have access to the number of options ahead of time, but still don't know how to loop through them...
So... How on earth do I loop through these variables?!? Basically I'd be thrilled to be able to do this:
trace(results_lv.option1);
trace(results_lv.option2);
trace(results_lv.option3);
and so on, until they've all been traced.

How can I make a bunch of variables from a for loop. for example for (var i=0; i<total; i++) {var bunch(i);}. that i make a bunch of variables named bunch1, bunch2, bunch3. I keep getting errors. I program and use so many different languages that I dont know if that can be done with AS3. my only other alternative i can think of is to create some sort of event dispatcher object array. but I dont know how to get them all to send events to one listener with there index number.

I have a list of strings that I add to an array, then attempt to set those values in a for-loop using data that I read in. The array gets updated, but the values the array contains do not. I also have an array of buttons that I update this same way that works great, but strings don't seem to work the same way. I have tried moving the string array to give it full scope, and still nothing...
public class test extends Sprite
{
// Declare a list of strings
protected var title0:String = undefined;

I have an XML document that loading into Flash. I have a dynamic text box on the stage that I am writing the XML to. My problem is, I have 6 group names that I am pulling from my XML file and I want to write each one of them to the text box and add a line break to the end. This is my code:
var group= this.firstChild.firstChild.childNodes;
for (var i=2; i<group.length; i++){
divBox['divInfoLinks'].htmlText =
[Code].....
When I trace [i] it lists all 6 names, however my text box only shows the last name in the array.

There is a bird, and you control its upwards movement with a key. It has thrust, gravity, it works fine. The problem is I have a bunch of icicles that come at the bird that he is supposed to avoid. I tried this first with math random to use as an x coordinate and than move across the screen, but the icicles had the same x-coordinates sometimes. I tried does not equal(!=) but that doesn't work. I made an array and each number that came out of the array I assigned a different variable. This works fine. I put this variable into the x-coordinate such as mc.x=((n)*60)+480. I did this for five different icicles. All their differnt variables have a different value, and I put them into the same function for each individual video clip, but they still don't go to the right coordinate. Here is the test code just for the initial coordinate of each icicle before it moves...////////////////////////////Quote:
var temp:Array = new Array()
for (var i:int=0;i<8;i++) {
temp.push(i);

I'm looping through an array and checking the elements to see if an element contains this text. the array is as following
[Code]...
i've narrowed down the problem to being the variable 'current'. If I replace the dynamic part to the string '_A_1' it works. That is why I entered the trace just above to see what its is checking against. I can see that they are both the same, but flash thinks otherwise.

I've got no idea how to phrase this, but is there a simple/efficient way to do something like this that doesn't feel hacky:?
[Code]...
I realize I can just trade the index number in the brackets for a function that returns the corrected index (after it works through the end of beginning of the loop as needed), but what's the best or most efficient way to do this? The damn 0 as the first position in an array really confuses me sometimes when trying to work these things out.

I am trying to loop my function through my array values continuously. I'm only able to get it to loop through one array value as intended. The long term goal here is the create a grid of movie clips that continuously change colors in random order (from preselected values). I'm new to actionscript and I have been racking my brain trying to figure this out. I'm unsure of how to send the function to all items in the array, and loop them all continuously, yet with random color patterns for each.

Hey guys, thanks in advance for any help, I'd be stuck all the time without these forums.
I have a custom class(Ball) and a .FLA. Ignore the custom class, it works fine, having a problem within my main FLA.
I'm getting repeated "Error #1009: Cannot access a property or method of a null object reference. at Environment_fla::MainTimeline/hitTest()".
I understand that this error means I'm asking it to reference something that's no longer there. I just can't figure out why I'm getting it, and how better to hitTest many objects in an array.
My game involves creating a bunch of balls that will fall into buckets. I need to keep track of how many touched the buckets, how many fell off the screen, and remove each accordingly.
Thanks again, very much appreciated.
Here is the code from my main FLA
[as]var ballTimer:Timer = new Timer(200);
var changeTimer:Timer = new Timer(50000);
ballTimer.addEventListener(TimerEvent.TIMER, throwBall, false, 0, true);
ballTimer.start();
changeTimer.addEventListener(TimerEvent.TIMER, changeColor);
changeTimer.start();
//Environment variables
var gravity:int = 1.5;
var friction:Number = .85;
var color:int = 2;
//score variables
var YellowScore:int = 0;
var BlackScore:int = 0;
var tBall:Ball = new Ball(new Point(mouseX, mouseY), new Point(Math.random() + Math.random()*5 + Math.random()*8), gravity, friction);
var ballArray:Array = new Array();
function throwBall(e:TimerEvent):void {
var tBall:Ball = new Ball(new Point(mouseX, mouseY), new Point(Math.random() + Math.random()*5 + Math.random()*8), gravity, friction);
tBall.addEventListener(Event.ENTER_FRAME, hitTest);
tBall.gotoAndStop(color);
addChild(tBall);
ballArray.push(tBall);
}
function changeColor(e:TimerEvent):void {
if (color == 1) {
color = 2;
return;
}
if (color == 2) {
color = 1;
}
}
function hitTest(e:Event) {
trace(ballArray.length);
for (var i = 0; i < ballArray.length - 1 ; i++) {
if ((ballArray[i].hitTestObject(YellowBucket1) && ballArray[i].currentFrame == 2)) {
YellowScore += 1; //trace(YellowScore); trace("Space");
ballArray[i].parent.removeChild(ballArray[i]);
ballArray.shift();
break;
}
else if ((ballArray[i].hitTestObject(YellowBucket1) && ballArray[i].currentFrame == 1)) {
YellowScore -= 1;
}
else if ((ballArray[i].hitTestObject(BlackBucket1) && ballArray[i].currentFrame == 2)) {
BlackScore -= 1;
}
else if ((ballArray[i].hitTestObject(BlackBucket1) && ballArray[i].currentFrame == 1)) {
BlackScore += 1; trace("BlackScore");
}
else if (ballArray[i].y > stage.stageHeight || ballArray[i].x > stage.stageWidth) {
trace("cleanUp");
ballArray[i].parent.removeChild(ballArray[i]);
ballArray.shift();
}
}
updateScore();
}
function updateScore() {
BlackBucket_txt.text = String(BlackScore);
YellowBucket_txt.text = String(YellowScore);
}

Here is my xml structure:
<question>
<q1> Who coined the term "Clinical Psychology"? </q1>
<answer> Lightner Witmer </answer>
<option1> Stanley Hall </option1>
<option2> Lightner Witmer </option2>
<option3> Henry P. David </option3>
</question>
I can loop through fine and pick out the questions and answers, then throw them into separate arrays. The problem I'm having is looping and pulling the options into a multidimensional array like such:
var one:Array = new Array( 3 );
one[0] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[1] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];
one[2] = ["Stanley Hall", "Lightner Witmer", "Henry P. David"];

this is part of an XML file I retrieve using AS3 E4X:
<links>
<link>
<label>Versions</label>
<href>http://mylink1</href>
[Code].....
I want to retrieve the values of labels, so I write:
document.links.link.label.text();
This returns VersionsConfigurations. I need this as Array ([Versions, Configurations]) but I would like not to use a loop. Is there any other way?

I'm working off the XML photo gallery tute found here: xml_flash_photogallery.htm. My wish is to have the array loop forward and backwards, so by clicking next you will eventually get back to the first value, and if you keep clicking previous you will eventually see the last value in the array.
I found some Scotty code (first line in the nextImage function) that enabled this function with the next button, but I can't figure out how to use it for the previous button.Here's the code:
previous_btn.onRelease = function() {
prevImage();
};[code]....

On the PHP site it was advised to do for loops in a certain way that I have not seen on any recommendations for AS3. I think I found about a 10 times speed increase and I thought I better check that I was not missing something (?) before going through my code and changing it. Very simple and fairly self explanatory (in the faster one the array.length is not calculated every time I think):
Code:
import flash.utils.getTimer;
var time:Number;
var myarray:Array = new Array();
myarray.length=2000000;
time=getTimer();

Actually, I'm HTML-coder, so I've recently confronted by difficulties with Flash. Its making the text banner. Flash needs to get variables from the following 'vars.htm' file:
myVar01=the_first_textDDDsecond_textDDDand_surely_ the_third_text&myVar02=DDD&myVar03=3
Where 'myVar01' contains the text, 'myVar02' is the text delimiter's look and 'myVar03' is the showing delay of texts. In truth, I've never seen the ActionScript before.
So, what I've done regarding that all:
ActionScript Code:
var data_lv:LoadVars = new LoadVars ();
data_lv.load("vars.htm");
data_lv.onLoad = function() {
[Code] .....
The problem is, the 'trace' shows me correct array looping but in Flash I see there's only one passage through the 'texts' array. But I need the infinite looping in Flash movie, instead of one.

I have some variables created on the main timeline and a mc called options which will be where those variables can be manipulated. A way I've tried to this is by creating a first array(array1) and populating it will all the variable names found on the main timeline, and another array(array2) containing the values of the variables the user has changed(which are displayed on some dynamic text fields). To make these changes, an "apply" button is pressed which will set the values found in array2 to the variables in array1.[code]How would you do this so that var1, var2... are updated properly according to the values found in array2?And because array2 contains strings(read from dynamic textfields), how do you deal with that since var1 and var2 are numbers?
