Flash :: Finding The Index Number In An Array

Finding An Index In An MC Array
FP v. 7. AS v. 2.0
_____________________

I have 10 MCs called "button0", "button1", "button2", etc. inside an MC called buttonsHolder.

I can access each "button" mc this way:

_root.buttonsHolder["button" + index]

This is what I have inside each "button" MC:

on (release) {
_root.buttonPanel[this].gotoAndStop("on");
}

I know I can find out button's number by using substring() on "this", but is there another way to find out the index of "this" inside buttonPanel? I couldn't find any methods or properties for that.

Any ideas?

Trouble Finding An Index Of An Array
Hi all,
I have posted this on the adobe forum and have got closer and closer to making this work.
I have parsed data from a CSV file and got it into an array. However when I try and find an index of an array, I am getting an undefined returned.

Code:
stop();
Array.prototype.findPos = function(value) {
var tAr = [];
for (var i = 0; i<this.length; i++) {
if (this[i] == value) {
tAr[tAr.length] = i;
}
}
return (tAr.length>0) ? tAr : false;
};
myVars = new LoadVars();
myVars.load("members.csv");
myVars.onData = parseCSV;
var TonyData = [];
function parseCSV(raw) {
var delim = (raw.indexOf("
") > -1) ? "
" : (raw.indexOf("
") > -1) ? "
" : "
";
var temp = raw.split(delim);
var fields = temp.shift().split(",");
for(var i=0;i<temp.length;i++) {
var row = temp[i].split(",");
if(row.length != fields.length) continue;
var tmpObj = {};
for(var j=0;j<row.length;j++) {
tmpObj[fields[j]] = row[j];
}
TonyData.push(tmpObj);
}
TonyData.onData
trace("Data Has Loaded");
trace("33's trace is..." + TonyData[33].Name_First + " " + TonyData[33].Name);
trace("10's trace is..." + TonyData[10].Name_First+" "+TonyData[10].Name);
var finder
//This finder value actually works, but introducing findPos causes it to fail finder = TonyData[10].ID;
finder = TonyData[10].ID.findPos(42703);
trace(finder);
if (!finder) {
trace("not found");
} else {
trace("The Array Index relating to the Membernum is: " + finder);
}
gotoandstop(2);
};
The annoying thing is that I can trace TonyData[10].ID but TonyData[10].ID.findPos returns undefined. I have also tried getIndex as well with the same results.
Does anyone have any experience in getting an index of a CSV parsed array, or can anyone see any holes in this code?
Any help would be greatly appreciated.
Regards,
Tony

Finding The Position Of An Array Index
i was wondering if you have an array value, can you find what number it is in the array's order. For example,

letters=new Array("a","b","c","d");
cnumber=letters.position["c"]
trace(cnumber);

so that cnumber=2. How would I go about doing something like this?

Finding Index Of Array Item
I'm working in AS2 and have created an array of movie clips (symbol_box[n]) with n ranging from 0 to 24. I want to be able to return the index of a movie clip (symbol_box[n]) when it is clicked so I can use it to access another movie clip in a second array. I need to be able to get the value of n... i.e. the index of the clicked clip. Any ideas? I'm sure it is simple!

Index Number Of Array Element
Hello all,

How does one find out the index number of a particular element in an array.

Say i have an array named fruit and it is populated with the following five fruits in this order: apple, banana, orange, pear and mango.
If for one reason or another i happen to be dealing with the element/value orange, using actionscript, how can i determine that its index number is 2.

Many Thanks.

How To Learn The Index Number Of An Array Node?
Hello all!

This is kind of complicated, I think. I have a multidimensional array:

myArray = newArray()

myArray[0] = new Item(buttonA, "nameA", ArrayA);
myArray[1] = new Item(buttonB, "nameB", ArrayB);
myArray[2] = new Item(buttonC, "nameC", ArrayC);
myArray[3] = new Item(buttonD, "nameD", ArrayD);

Thus, on the main screen there are 4 buttons (named ButtonA - ButtonD) and a dynamic text which displays a string according to the variable: Screen.

I am trying to make a function so when I onMouseOver one of the buttons, such as ButtonA the function finds out what Array ButtonA belongs to and sends "nameA", which is also part of myArray[0], to the dynamic text, Screen.

If someone would be so very kind as to help me, I would be very grateful.

***. Arrarys, Finding Index, Loading Called Pic From Found Index
I am fairly new to flash, so thanks for bearing with me - here is my problem -
1. I have a bunch of associated arrays, populated from an xml file.
2. I have a dyn mc that displays thumbs, based on the info from the arrays.
3. if the user clicks on the thumb, I want the on release to trigger (among other things) a function that will find the index of, say, "houseID" so I can then apply that index in loading up a different(big) jpg , and other info pertinent to that thumb.
here is my code for the button:
on (release) {
//carry ID being the variable passed thru "oneHouse" function
CarryID=this.houseID;

trace("houseid"+houseID);
_parent.oneHouse(CarryID)
//"big" being the frame label
_parent.play("big")
}

-----------------------
here is code from a frame -

foundIndex = findByID(CarryID);
if (foundIndex != null) {
/*set dynamic textbox values from Arrays
all this stuff is not set up yet...
txtLocation = houseLocationArray[foundIndex];
txtBed = houseBedArray[foundIndex];
txtBath = houseBathArray[foundIndex];
txtPrice = housePriceArray[foundIndex];
//set dynamic jpeg clip from value of photoArray
loadMovie(houseBigpicArray[foundIndex], BigphotoClip);
*/

trace("foundIndex!=null");

}
else{
trace("foundIndex really=null");
}

function findByID(houseID) {
//loop through the IDArray
for (j=0; j<houseIDArray.length; j++) {
//if the passed argument equals an Array value...
if (houseIDArray[j] ==houseID) {
//return the index of the matching value
return j;

}
}
//if nothing is ever found, return null
trace("foundIndex2=null");
return null;
}

gotoAndStop("big");

}

thanks for anyone that can help me with this!!

Finding Index Or Position Of Certain Attributes In Xml File?
Hi,

I've been getting to grips with xml and as3 but cant figure this out....

If I retrieve the value in a node from the number of the node, how do i then find the number of the node from the value. (confused?)

this is my code:

Code:

var hx:XML =
<hmv>
<level> <area> Music </area>
<subject> <area> Radio </area>
<content>Live Stream </content>
<content>Archive</content>
</subject>

<subject> <area> Library </area>
<content>Brian Ferry</content>
<content>Harvey GoldSmith</content>
<content>The Levellers</content>
<content>The Kooks</content>
<content>SugaBabes</content>
<content>Take That</content>
</subject>
</level>
</hmv>

trace(hx.level[0].child("area"));

var neededVal:String = hx.level[0].child("area");

///// this gives me the result "Music"

How do i then get the number 0 back from putting in the name Music?

should be relatively simple, i'm sure i just haven't been able to find this explained in any tutorials and its quite a difficult subject to search for.

any help greatly appreciated,

thanks

Finding The Mid-range Number
Hi guys.

What's the quickest way of finding the mid-range number in an object that contains three numbers? I'm trying to find a way of returning the actual property name instead of the value.

Here's an example object...

ActionScript Code:
var colour:Object = { r:10, g:100, b:200 };

... ideally "g" should be returned from a function because it's the mid-range number.

If two values are the same then either property could be returned. For example {r:100, g:100, b:200} could return "r" or "g"... and {r:200, g:20, b:20} could return "g" or "b"... and so on.

I'm stuck on this one for some reason so any help or pointers would be great.

Cheers,
Si ++

[F8] How To Call Function By Number/index?
I have a bullets that I shoot into enemies and there is different kind of bullets and enemy should call function based on bullet type. I have a code that checks if bullet hit enemy is like:
for(i=0;i<=_root.bullets.length;i++){ //(bullets is array)
if(this.hitTest(_root[_root.bullets[i]])==true){

React on the bullet type.

}}

For example I have a variable in each type of bullet like type=1;type=2 etc...

I know I can call the way:
if(_root[_root.bullets[i]].type==1){function1()}
if(_root[_root.bullets[i]].type==2){function2()} etc...

Is there way to call a function without "if" but some like indexed functions??
Like function[type]() or something. I mean to call a function with "type" variable index, that is variable which describe bullet type.

Unrepeating Rando Number From Index

I know that there's been many similar post about this, but I've searched the forums and can't actually find a working script that fits this description...

Creating An Index For Jpgs Loaded By Number
Hello everyone...

I am using a simple gallery movie to allow users to browse through
a series of images.

in the first frame of the movie i use this actionscript:

var wimg = 1;
var url='image/' + wimg + '.JPG';

then in the second keyframe:

loadMovie(url, "bitmap");

then in the last frame i use:

gotoAndStop(2);

then for the left arrow I use:

on (release) {
if (wimg eq 1) {
wimg = wimg;
url = 'image/' + wimg + '.JPG';
play();
} else {
wimg = wimg - 1;
url = 'image/' + wimg + '.JPG';
play();
}
}

then the right arrow:

on (release) {
if (wimg eq 100) {
wimg = wimg;
url = 'image/' + wimg + '.JPG';
play();
} else {
wimg = wimg + 1;
url = 'image/' + wimg + '.JPG';
play();
}
}

This works fine, loading in numbered images from the the image/ directory.
The question I have:
Is there a way to visibly number the images, and allow for a index to call up an image using its number?
and if so, how in the world do i do this??

Please Help...

Thank you in advance

I Know The Line Number. I Need The Last Char Index Number Of The Line.
Hi,

I have a multiline wrap textbox which is dynamic and has a variable assigned to it. I am importing text into this textbox. If the amount of text exceeds the height size of the textbox I want to split the text into two parts, so the part which exceeds the textbox ( the text which is not visible unless you scroll down) will be moved into another textbox located below the first textbox.

I know how to get the location of the last visible line in the textbox. I simply use

LastVisibleLine=MyTextbox.bottomScroll;

Now I have the location of the last visible line so my question is:

How can I get the location of the last character in the last visible line in the textfield?

Is it possible to count the lines in a textfield when the text is wraped. I've tried to count "
" and "
" and they don't detect the wrapping.
( Wrap: When the textfield detects if a line has reached the width of the texfield it automatically breaks the line so it will fit the textfield. )

Thank you.

Finding Current Frame Number Of FLV Movie (playing In Flash 8 Player)
Hi,

I want a reliable method to find the current frame of a flv movie, being played in the flash 8 player.

I can find the frame rate and current playheadTime of the movie, but I am not sure if it's gonna lead me to exact frame number.

Here is little code snipppet which I am using...

HTML Code:

import mx.video.NCManager;
import flash.external.*;
import mx.video.VideoPlayer;
/* The following code forces the compiler to include the NCManager
class in the current SWF file, which the VideoPlayer class requires
by default. */
var _dummy:NCManager;
var my_vp:VideoPlayer;

my_vp.addEventListener("playheadUpdate", doPlayHeadUpdate);
my_vp.autoRewind = false;
my_vp.autoSize = true;
my_vp.bufferTime = 0;
my_vp.maintainAspectRatio = true; // default
my_vp.playheadUpdateInterval = (1000/15);

//Water.flv is 15 fps movie - I want playhead interval so small that it would update it every frame

my_vp.play("water.flv");

function doPlayHeadUpdate(eventObj:Object):Void
{
trace(" [" + my_vp.playheadTime + " sec of "+ my_vp.totalTime + "] => Frame Rate: " + my_vp.metadata.framerate);
//Print Current Frame Number Here...
//NOT SURE IF THIS IS THE RIGHT WAY TO DO IT... so THAT I WON'T MISS ANY FRAME
trace("Current Frame : "+(my_vp.playheadTime * my_vp.metadata.framerate);

}
Thanks in advance. Please let me know if there is any way of directly finding the current frame of flv movie.

ARRAY Element Value - Not Array Index Value
Hi all -
Have a small problem converting the below variables from PHP into a useful Ascript Array. I keep getting the value of the array index, rather than the value of the variable in question.

So I know I have 3 rows in my database (totalRows var),
and I have a incremental values for the "recordId"'s (which correspond to the record ID in the db).

totalRows = 3

recordId0 = 1
recordId1 = 5
recordId2 = 6

this is the code I am using:

Code:
function extractMenu() {
//returned vars (FYI): totalRows=3&recordId2=6&recordId1=5&recordId0=1&result=okay&
this.menuArray = new Array();
with (menuLoad) { //menuLoad is the LoadVars object holding PHP vars.
for (i=0; i<=totalRows-1; i++) {
menuArray[i] = recordId + i;
trace(menuArray[i]);
//the trace returns:
//0
//1
//2
//I was expecting the values:
//1
//5
//6
}
}

any takers?

Help - Getting Array Index 0 With MultiDim Array

Now that the arrays have become multidim the chapter heading names are all whacked. The chapter subpages are fine though.. When the file is previewed it's pulling a 0 index for one chapter header, but after that it's pulling the supbage indexes. Basically the headers of the menu need to be the [0] of the arrays.

Any help or suggestions would be helpful

How To Index An Array
I should know this; I think I once did . . . but for some reason my brain is frazzled and I am turning up nothing, not in books, nor on the internet.

All I want is to return the index of an array element. Really, that's it.

I am storing ID values for news stories in an array and I want to make a "previous" and a "next" button -- so I want to take the index of the current ID, add or subtract one, and then send that value to my loading function.

An Array / Index Issue
Hi,

Does someone know an array method (or something else) that returns the index of an element of this array.

For instance :

array[0]="joe";
array[1]="nono";
array[2]="dudul";
array[3]="titi";

If I ask to this "method" the index of the element "joe", I expect it to return 0.

If I ask to this "method" the index of the element "dudul", I expect it to return 2.

It sounds easy... did not find the method through the actionscript dictionnary though...

Thanks for your help
