Flash :: Return Value From Function

AS2: What Datatype Should A Function Return, If It May Not Return *anything*?
The title of this post may not make much sense, let me explain...

I have a function:

findSurface(origin:Point, vector:Point, attempts:Number):Point {...}

The function has an obscure use, but the idea is thus: given those three arguments, returns a point IF the 'line' (created by the origin and vector arguments) intersects the object the function is called on. [but that is another story...]

More importantly, if there is no point of intersection at all, what should the function return? Void? Null? Undefined? Object? Or can I use one of those return types instead of Point incase the function does not encounter an intersection?

I'd be glad to try explaining better if anyone might know, thanks.

Return Function Name (Function => String)
I keep coming across problems where it would be really convenient to get the name of a function in string format - like arguments.callee only a string instead of [Function, Function].

I haven't thought of a way to do this but in my head the keywords 'prototype' and 'override function' keep coming up - albeit that seems like a horrible horrible idea, but Function does extend Object so...thoughts?

Return From Function Called Within Function
How do I return the output from getTrialsHandler to getTrials when calling getTrials?

// THE CALL
trace( getTrials(1,16) );

// THE FUNCTIONS
function getTrials(day, userID){
var pc:PendingCall = service.getTrials(day, userID);
pc.responder = new RelayResponder(this, "getTrialsHandler", null);
}

function getTrialsHandler(re:ResultEvent, day){
if(!re.result){
trace("ERR: load trials for day"+day);
} else {
trace("SUC: load trials for day"+day);
if(re.result[1] > _root.currentDay){
goto = "closed";
} else if(re.result[0] < 5){
goto = "open";
} else if(re.result[0] == 5) {
goto = "full";
}
out = (re.result[0]+"::"+re.result[1]);
}
return out;

Function =>return Value ?
hey,

I wonder if anyone has any ideas how to do this :
I have a function written

Code:
javascript.openConfirm = function(message_str){
responsSet_bol ="false";
getURL("javascript:var respons = confirm('" + message_str + "');void(0);javascript:window.document.popup.SetVariable('respons_str',respons);javascript:window.document.popup.SetVariable('responsSet_bol','true');");

return respons_str;
}

what i want to accomplish is a confirm window(ok, cancel) and I want the answer to be returned
I call this like so:

Code:
respons = javascript.openConfirm("wilt ge dit?");

the problem is that the string is returned, before an answer is set by the confirm window.

does anyone have any ideas how to do this?

How To Return In This Function?
Hi guys, hope you can help me on this one.
I have a class to load an XML file. I’m trying this:

Code:
package {
import flash.net.URLRequest;
import flash.net.URLLoader;
import flash.events.*;
public class retornaXML{
private var _xml:XML;
public function retornaXML() {
cargarXML();
}

private function cargarXML():void {
var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, xmlLoaded);
loader.load(new URLRequest("LocalData.xml"));
}
private function xmlLoaded(e:Event):void {
_xml = new XML(e.target.data);
trace(_xml);
//THE TRACE HERE WORKS PERFECT AND RETURNS THE XML
}
public function get elXML():XML {
return _xml;
//THIS RETURNS null
}

}
}
I want something like this:

var mivariable:retornaXML = new retornaXML();
trace(mivariable.elXML);

but this trace returns null, since the xml file (I think) is not loaded yet. What should I do?

Thanks in advance.

How To Return A Value From A Function, Maybe
Hello, first post :)

Here is my problem: In the attached .fla, I have a wheel of fortune style game which stops at a random point.

I've been able to test where the wheel stops using hitTest, and would like to output the result to the trace (for now).

My if statement which does the hitTest(s) is nested inside the function which slows and stops the wheel spinning (slowdown).

The problem is that function uses onEnterFrame, so my trace messages go into an endless loop.

So my question is how to test that the wheel has stopped spinning from outside the function, where to put the hitTests? My guess is it could involve getting the function to return a value, but I'm not sure.

Thanks in advance.

Function And Return
Hello,
I'm pretty newbie to actionscript 2, so my question might sound easy.
I can't understand the use of 'return' in a function.
If I write

ActionScript Code:
function some(num:Number) {
number = num * num;
}
some(8);
trace(number);

well, it works.

I could also have written

ActionScript Code:
function some(num:Number) {
var number = num * num;
return number;
}
some(8);
trace(number);

It works also, but I'm wondering why not using the first case?
Is 'return' used only where variable names might conflict with the rest of the code?
And, if I use methods within the code, the results of which are global, why should I use the return keyword, which is to resolve the 'locality' of functions?

thank you very much
m.

Function Return
hey,
I'm trying to make a function in flash to call a confirm dialog box through javascript. I wrote this function to open the confirmdialogbox and then storing the value in a variable respons and then sending this variable to the swf. At the end I return the value.

Code:
javascript.openConfirm = function(message_str){
responsSet_bol ="false";
getURL("javascript:var respons = confirm('" + message_str + "');void(0);javascript:window.document.popup.SetVariable('respons_str',respons);javascript:window.document.popup.SetVariable('responsSet_bol','true');");

return respons_str;
}
Now if I call this function doing this :

Code:
respons = javascript.openConfirm("ben je zeker dat je dit wil?");
the returned value isn't stored in the respons variable.
The reason I think is because the value is returned before you click one of the 2 buttons(ok or cancel).
does anyone have any idea how to avoid this. or an other method so the return value is the same as the button clicked

I really need some help, cause I'm stuck

[Type Function] Return? Wtf Is This?
I have script that creates an array of numbers, randomly choses one from that list, assigns this number to one of the MC's depth, removes it from the array, then moves on to next MC. The purpose is to randomly generate Depth levels.

v_?? are variables
a_?? array
c_?? Clips (MC's)
i_?? interger counters
f_?? functions

when I "trace" the result for the FishA, it displays [Type Function], OR reports the depth is -16383 (or some ridiculous #)

what have i done wrong? What does [Type Function] mean?

onClipEvent(load){
v_Depth = 0;
a_Depth = new Array();
for(i_Count = 0; i_Count < 30; i_Count ++) {
a_Depth [i_Count] = i_Count;
}
function f_SetupDepth(fv_MC) {
v_Depth = random(a_Depth.length);
trace(v_Depth);
_root[fv_MC].swapDepths(Number(v_Depth));
a_Depth.splice(v_Depth,1);
}
f_SetupDepth(c_Column1);
f_SetupDepth(c_Column2);
f_SetupDepth(c_Column3);
f_SetupDepth(c_Column4);
f_SetupDepth(c_Column5);
f_SetupDepth(c_Column6);
f_SetupDepth(c_FishA);
}

Return Array From Function?
hi,

i have a function that takes an xml file as an arguments, reads the data and puts it into an array.

how do i get that array returned outside of the function?

i've tried " return array; " to no avail.

code:

function loadList(filename) {

audiolist = new XML();
audiolist.ignoreWhite = true;
audiolist.load(filename);
trackArray = new array();

audiolist.onLoad = function(success) {
loaded = true;
totalNodes = audiolist.firstChild.childNodes.length;

for (a=0; a<totalNodes; a++) {
thisCD = audiolist.childNodes[a]
tracklist = thisCD.childNodes.length;

for (i=0; i<tracklist; i++) {
trackArray.push(thisCD.childNodes[i].childNodes[0].nodeValue + ":" + thisCD.childNodes[i].attributes["id"]);
}

}
return trackArray();

}
}

Return XMLNode From Function
Why is it that the trace from within the readXML function traces the XMLNode as expected, but the trace from within the onLoad returns undefined?

Shouldn't they trace out the same thing. Why doesn't the readXML function return the XMLNode?

ActionScript Code:
var myXML:XML = new XML();
var itemsNode:XMLNode;
var imageNode:XMLNode;
submitBut.onRelease = function() {
myXML.load("thisXML.xml");
}

myXML.onLoad = function(success) {
if (success) {
trace("From Load: " + readXML(myXML, "Items");
myText.text = readXML(myXML, "Items");
} else {
myText.text = "There was an error loading.";
}
}

function readXML(startNode:XMLNode, targetNode:String):XMLNode{
if (startNode.hasChildNodes) {
for (var i = 0; i < startNode.childNodes.length; i++) {
if (targetNode == startNode.childNodes[i].nodeName) {
trace("From read: "+startNode.childNodes[i]);
return startNode.childNodes[i];
}
readXML(startNode.childNodes[i], targetNode);
}
}
}

Return Loaded XML From Function?
Hey everyone

I'm trying to figure out how to do this. I'm making an XMLLoader class, that I want to be able to use like this:

Code:
var myXML:XML = XMLLoader.load("SELECT * FROM table");
trace(myXML); // traces the loaded XML
I just can't figure out how to make the load function inside XMLLoader return the XML object... I can easily register an evenlistener that calls another function when the XML is loaded.. but how do I then make the load function return this XML? I want to do this:

Code:
package
{

public class XMLLoader
{
public function XMLLoader()
{
trace("Constructor called");
}

public function load(sql:String)
{
// Call a php site to recieve XML
// add listener to notice when XML is loaded
// return the loaded XML
}
}

}
The thing is, that I want to keep all event-stuff inside my XMLLoader, so I can use the class like the first example.

One way around it is to make a while loop inside the load function that checks whether a boolean is tru or false. When the XML is loaded, I set that boolean to true and the laod function returns the XML. But it's really taking up all the CPU power, and NOT a nice solution..

In a bunch of other programming languages you have the sleep function, that let's you sleep e.g. a part of a functions code until a variable is set, and then you can return it only when it is set.

How do I do it?

Different Return Values For A Function?
Hey,

I have a function which could return different types of possible datatypes,
depending on the input. What should i set to be the return value of the function in the definition?

Isn't this ok:

ActionScript Code:
public function getSubData(inDataType:string):Object {
var obj_to_return:object;
if (inDataType == "arr") {
obj_to_return = global_array; //An array with some sprites in it.
}
else if (inDataType == "sprite") {
obj_to_return = global_array[0]; //A sprite
}
return obj_to_return;
}

When using the function in my code:

var sprite_obj:sprite = getSubData("sprite");

i get:
"1118: Implicit coercion of a value with static type Object to a possibly unrelated type..."

Is this possible?
Thanks,
Guy

Return Function W/ SetInterval
I want to have a function that returns a value...this function will be called by setInterval.

The problem is...the function will return a value. I want to make sure that value goes to the proper variable. How can this be done?

Code:
EX:

function test(someInput){
return (someInput = 'dork');
}

interval_ID = setInterval(test, 10000, someInput);

// let's say i have a variable call "show"
// show should contain the return variable
Now, I tested out to see if I can pass a variable by address or reference to avoid 'return'...but it doesn't work. However, arrays can be used b/c it can be passed by referenced.

For example:
function test (theArray){
theArray[0]='dork';
}

var myArray = new Array();

myArray[0] = 'not a dork';

zeroArray(myArray);

trace (myArray[0]);

If you know how I can accomplish the same concept w/out using arrays, let me know.

thx in advance

Use Return Key To Trigger Function?
I've got a little form in a movieclip where the student is to do some simple subtraction, then click the Record button to enter the data into a table. Problem is that if someone types in the answer, they naturally want to hit the Return key to enter the data, however, it instead puts a carriage return in their answer and when they try submitting with the Record button, it checks their answer and it is now wrong since the added carriage return does not match the answer they should have. Is there any way to make the Return key trigger the recordIt() function? Here is my code:

Attach Code

recordBtn.addEventListener(MouseEvent.MOUSE_DOWN,recordIt);

function recordIt(num) {
if (diameter.text == "85.80") {
if (difference.text == "1.10") {
MovieClip(this.parent).growth.d1999.text = "85.80";
MovieClip(this.parent).growth.g1999.text = "1.10";
helpText.text = "Good job. Click the button below to do the next year's measurement.";
recordBtn.visible = false;
} else {
helpText.text = "Incorrect result. Try again.";
}
} else {
helpText.text = "Incorrect diameter. Try again.";
}
}

Function, Return Problem
Hi,

I think its a matter of function scope, but I can't get my head around it. I'm simply loading an external file with a variable that I want to pass from the loadVars function. It goes something like this.

count.txt - file
nr - the name of the loaded variable that is in the file
working - a dynamic textfield for the working number
notworking - a dynamic textfield in which I get "undefined"

Code:
loadVarsNum = new LoadVars();
loadVarsNum.onLoad = function(success) {
if (success) {
trace("loaded");
_root.working.text = this.nr;
} else {
trace("not loaded");
}
};
loadVarsNum.load("count.txt");

_root.notworking.text = nr;
Is it because I need to add "..cess):Number'" and in the function "return nr;" ? Or is it because I don't have the "nr" variable when I assign it to the second textfield?

Thank you.

bHandle.lineTo(bWidth, 0);
bHandle.lineTo(bWidth, bHeight);
bHandle.lineTo(0, bHeight);
bHandle.lineTo(0, 0);
bHandle.endFill();
bHandle._x = bX;
bHandle._y = bY;
return bHandle;
}

Code:
var Handle:MovieClip;
createButton(400, 250, 0xFFFF99, 0xFFFF99, 30, 80, Handle);
//X, Y, Colour, Colour, Height, Width, Handle

Handle._visible = false;
some reason when I try to hide Handle, it doesn't do it, & trace's dont do anything either
it is suppost to create the button & store it in any handle I give it

SetInterval To Return A Value From A Function?
Got a little problem here guys... the story goes like this:

ActionScript Code:
function foo() {

function setValue() {
value = "ok";
}

return value

}

The problem here in my case is that the function setValue takes a couple of milliseconds to set the value variable. And when executing foo it returns undefined instead of "ok".

no problem, i'll just have foo return value with a setInterval:

ActionScript Code:
function foo() {

function setValue() {
value = "ok";
}

function checkIfSet() {
if (value) {
return value
}
}

setInterval(checkIfSet, 100);

}

...Ofcourse this doesnt work. Flash complains that there is no return value for the function foo.

What i'd need is fooScope.return value, if you catch my drift, but thats wishful coding

Can anyone help me out?
Thanks

How To Return A Value From OnEnterFrame Function?
Dear All,

I've already learn about onEnterFrame function...
I need to do so, but I've found that the value cannot pass from the function.
Here are my coding:

Code:

function GetSubCat() {
loadVariables("GetData.dat", this);
this.onEnterFrame = function() {
if (CountCat != undefined) {
SubCat = new Array();
for (j=1; j<=CountCat; j++) {
SubCat[j] = this["SubCat"+j];
}delete this.onEnterFrame;
}
};
return SubCat;
}

On the code above,
I've load some variables from the file: "GetData.dat" which contain CountCat, and SubCat1.... like

Code:

&CountCat = 3&
&SubCat1 = The first Cat&
&SubCat2 = The Second Cat&
&SubCat3 = The Third Cat&

I want to put all the SubCats to an Array.
And return the Array to the script.
for example:

SubCatArray = GetSubCat();

So that the SubCatArray (Array data type) can get the variables from the function.

can anyone help!?

Thanks a lot!

Function Does Not Return Date Object

If functions are capable of returning objects, and Date is an oject, why does the following code consistently return "myDate" as undefined?

Code:
function cleanDate(date) {

var x = date.indexOf(" ");
var y = date.slice(0, x);
// strip apart month, day, and year
z = y.split("/", 3);
// create Date object and return it
myDate = new Date(z[2], z[0], z[1]);
return myDate;
}
hireDate = "10/25/2002 12:00:00 AM";

Return From .onLoad Function Syntax HELP
syntax nightmare ...
I would like to load a XML file and onLoad have it return the text of a specific node to where the LOAD function was called from. I have it all worked out except for figuring out how to RETURN from a .onLoad function. Can I return from a .onLoad? See the code below. The mainXML.onLoad fires correctly, and the XML loads successfully. It does not correctly return the node value back the the function named "fLoadXML" however. It returns this:
"myVar: [type Function]"

That leads me to think that it is returning just this object "mainXML.onLoad" and not the value that is returned to it.

Code:
// define the main xml object
var mainXML:XML = new XML();
// functions that loads the XML data
function fLoadXML(file) {
mainXML.ignoreWhite = true;
mainXML.load(file);
//what to do when it loads

Better Way To Write This Tiny Return Function...?
I have a small function that returns a value for x. I want to find an easier way to determine the 'forward' positions in the array. For instance, if I am at position 4 (out of 4) in the array, and I want to know the next two positions, i.e. I want this function to return 0 and 1. I want to avoid hard coding for each case as you'll see below.

Here it is:

code:
array = new Array(0,1,2,3,4);
currentPOS = 4;

function displayNext(x) {
var x = x;
if (currentPOS + x == (_root.array.length + 1)) {
x = 0;
} else if (currentPOS + x == (_root.array.length + 2)) {
x = 1;
} else {
x = currentPOS + x;
}
return x;
}

displayNext(1);
displayNext(2);

Thanks for any help!

How To Return Data Within A Function? (a Twist)
im trying to create a generic and reusable function that loads xml data and returns it to a variable..

basically, i want a function that would go fetch data and return that to the variable that's calling it..

here's my current function.

PHP Code:

_global.loadXML = function(link){
    myXML = new XML();
    myXML.ignoreWhite = true;

    myXML.onLoad = function(success){
        trace("loaded");

        if(success){
            trace("success");
            xmlData= myXML.toString();
        }else{
            trace("error");
            xmlData="ERROR";

        }
        return xmlData;

    }

    myXML.load(link);

}

then call it like so

PHP Code:

filedata= loadXML("profile.txt");

the variable filedate should have the data returned y the function. however....

The above script should work except... the return funcion:

PHP Code:

return xmlData;

is within another function INSIDE that function... therefore, returning the data only returns it to the PARENT function and not to the variable that's calling it..

can you guys see a solution here?

Advanced Function Return Problem.
I need some information maybe somebody whom reads this will have had the same problem.....I have a function wich uses a return value from another function.
The second function does some complex mathmatical processes on the data and then the end result is returned at which time the first function uses the returned data to perform its function but (here is the problem) function one doesn't like to use the data returned from function 2 but if i replace function2 (the complex function) with a simple function then everything works fantabulous....so is there some special rule i need to follow to use data returned from a complex function?

complex function code.....doesn't like to use the returned secsxx.....keep in mind though that the returned value (secsxxx) will work in a trace or in a dynamic text box it just doesn't work when the first function tries to use it to perform its function.

Code:

minutesx = min;
_root.view_btn2.onPress = func1x;
function func1x() {
var datex = new Date();
_root.targetMillix = datex.getTime()+((minutesx*60)*1000);
}
function maincountxx() {
var datex = new Date();
var millix = this.targetMillix-datex.getTime();
if (secsx<=9) {
var secsxxx = "0"+secsx;
} else {
var secsxxx = secsx;
}
if (minsx<=9) {
var minsxxx = "0"+minsx;
} else {
var minsxxx = minsx;
}
if (millix>0) {
secsx = Math.floor(millix/1000);
minsx = Math.floor(secsx/60);
secsx = secsx%60;
minsx = minsx%60;
timer_txt.text = minsxxx+":"+secsxxx;
// countdown2 is a dynamic text field
} else {
timer_txt.text = "05:00";
}
//code which reacts to timer reaching 0
if (millix<=0) {
msg2.text = "default";
// code which reacts to timer have time.
} else if (millix>0) {
msg2.text = "alternative";
}

return secsxxx;
}

[mx04] Return Function Problems
Flash MX 2004. AS 2.0

Hey everyone, trying again with a simpler post. I'm having trouble figuring out how to make a function that is part of an image viewer return the image's width to a variable, which I'm going to use in an equation to center the image on the stage depending on how wide it is. I'm pretty sure the function should work since I got the code out of a flash book, the second part is the part i wrote and need help with. Thanks in advance

Here is the code for the function

public function getImageWidth ():Number {
return container_mc.image_mc._width;
}

And here is where I refernce the function on a loading button

on(rollOver) {
var ImageW:Number = viewer.getImageWidth();
}

Is that the correct way to make a variable = the returned number of the function?

Use Return/Enter Key To Trigger Function?
I've got a little form in a movieclip where the student is to do some simple subtraction, then click the Record button to enter the data into a table. Problem is that if someone types in the answer, they naturally want to hit the Return key to enter the data, however, it instead puts a carriage return in their answer and when they try submitting with the Record button, it checks their answer and it is now wrong since the added carriage return does not match the answer they should have. Is there any way to make the Return key trigger the recordIt() function? Here is my code:

recordBtn.addEventListener(MouseEvent.MOUSE_DOWN,r ecordIt);

function recordIt(num) {
if (diameter.text == "85.80") {
if (difference.text == "1.10") {
MovieClip(this.parent).growth.d1999.text = "85.80";
MovieClip(this.parent).growth.g1999.text = "1.10";
helpText.text = "Good job. Click the button below to do the next year's measurement.";
recordBtn.visible = false;
} else {
helpText.text = "Incorrect result. Try again.";
}
} else {
helpText.text = "Incorrect diameter. Try again.";
}
}

Event Listener For A Function Return
Hey All,
I am wondering if there is a way to have an EventListener listen for the return of from a class? I am also wondering if I am going about thinking about this the right way. Here is my code:

This snippet creates a splash screen:

PHP Code:

public class Main extends MovieClip {
function splashScreen() {
            var mainSplash:Splash = new Splash //This is my splash screen class
            addChild (mainSplash) //adds the main splash graphic
        }
}

And this is the Splash Class

PHP Code:

package roids {

        import flash.display.*;
        import flash.events.*;
        import flash.ui.*

    public class Splash extends MovieClip {
        public function Splash() {
            trace ("Splash Initialized")

            //Creates a button to start the program
            var mainStartButton:MainButton = new MainButton
            addChild(mainStartButton)
            mainStartButton.x = 275
            mainStartButton.y = 300
            mainStartButton.addEventListener(MouseEvent.CLICK, buttonClicked)

        }
        function buttonClicked(event:MouseEvent){
            /* what can I put here to return to the parent that a button has been clicked?*/

        }
    }
}

In essence I want the main class to know that the mainSplash is returning that the mouse was clicked. Whats the best way to do this?

Function Can Return Multiple Type
Hi there.

Ok, I would like to know if someone know how to achieve this.
I have a superclass (singleton) with a static function returning the type of the class.

ActionScript Code:
// create the singleton
public static function createWorld(owner:MovieClip):superClass {
// init the superClass
superClass.instance.init(owner)
return superClass.instance;
}

I have a child class which is inherit from the super class.

The thing is I want to be able to create my childClass instance like that

ActionScript Code:
var gameworld:classes.childClass = childClass.createWorld(this);

but I have a type mismatch as it return the super class type.

Any idea?
I know that I could get rid of the return type and it will be ok, but I wonder if there is another way to achieve what I want.

Cheers

How Do I Return A Value If The Function Calls A Load()
Hey guys,

I am writing a function that I would like to ping a web service, which sends back JSON data, then return data from the JSON...

i.e. trace(getJSONData(1234));

How can I get it to WAIT until the data is loaded then return what I want?

Right now I have this to get the JSON data in:

Code:
articleFeedRequest.url = "http://url_to_go_to.tv/rpc/get/feed(article_id_exact=" + articleNumber + ")" ; // get the data from the userNumbers feed.
articleFeedLoader.load(userFeedRequest);

articleFeedLoader.addEventListener(Event.COMPLETE, decodeJSON);
How can I package all this into a function itself so I can call the function in a trace or whatever to return the data I am looking for...without waiting for the Event.COMPLETE to trigger a new function. I want to have the same function grab the data AND return it.

Know what I mean?

Thanks a jig!

Return Value Of Function After EVENT Does Not Work
Hi again,

I made a game and put it into one function. And i want the score given back to my main program: (here only as a trace)

ActionScript Code:
trace(MyGame());

and this is my game (not original... is too long to insert here)

ActionScript Code:
function MyGame ():int {

...

var example:int;

var myTimer:Timer = new Timer(10, 1000);
myTimer.addEventListener(TimerEvent.TIMER, fu);
myTimer.start();

fu(){
increases example++ a few times;

trace("test");
}

return example;
}

now let me explain: when the "fu" function starts, everthing is fine, but when the Timer ends, the "fu" functions will not be left so that the "MyGame" functions does not return the "example" integer...

When i insert a trace with a text, ("test") the trace is printed, but the function will not be left... so i never get my example-int back out of the MyGame function....

why???

My Function Will Not Return A Sound Object
I've run many tests on the script below. The function "charToWord" is not casting a sound object properly like it is supposed to. These sounds are all properly defined (code not shown) and the sounds do work, but not when they are passed from the charToWord function. Should I be casting as something else?

I get the following error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

ActionScript Code:
function getIdent(myIdentIs):void
{
soundArray.push(charToWord(myIdentIs.charAt(3)));
soundArray.push(charToWord(myIdentIs.charAt(4)));
soundArray.push(charToWord(myIdentIs.charAt(5)));
}

function charToWord(char):Sound
{
switch (char)
{
case 1 :
return soundOne;
break;
case 2 :
return soundTwo;
break;
case 3 :
return soundThree;
break;
case 4 :
return soundFour;
break;
case 5 :
return soundFive;
break;
case 6 :
return soundSix;
break;
case 7 :
return soundSeven;
break;
case 8 :
return soundEight;
break;
case 9 :
return soundNine;
break;
case 0 :
return soundZero;
break;
}
