for (var a:uint=0; a<tstArray.length; a++)

{

var x:Number = Math.floor((Math.random()*tstArray));

trace(x);

tstArray.splice(a,1);

}

i have this code but it doesnt do exectply what i want it to do. Im trying to generate a signle random number per click between 1 and 3 and when all numbers have been used up, remove this click listener.

    this is how the wntire code looks like and its being pulled into another class when a click occurs:

    package

    {

    */import flash.utils.Timer;

    import flash.display.Sprite;

    import flash.events.MouseEvent;

    import flash.display.MovieClip;

    import flash.events.Event;

    import flash.events.*;

    import flash.media.Sound;

    import flash.events.TimerEvent;

    import flash.media.SoundChannel;

    import flash.media.SoundTransform;*/

    public class farm_Part1

    {

    public function randomAnimal()

    {

    var tstArrray:Array = [1,2,3];

    tstArray.shuffle();

    ///////////////////////////// change nothing below /////////////////////////////////////////

    function shuffle(a:Array)

    {

    var p:int;

    var t:*;

    var ivar:int;

    for (ivar = a.length-1; ivar>=0; ivar--)

    {

    p=Math.floor((ivar+1)*Math.random());

    t = a[ivar];

    a[ivar] = a

    ;

    a

    = t;

    }

    }

    }//randomAnimal

    }//class

    }//package


    use:

    var fp1:farm_part1=new farm_part1();

    and any time you want to randomize an array use:

    var tstArray:Array = fp1.randomizeF([1,2,3]);


    package

    {

    */import flash.utils.Timer;

    import flash.display.Sprite;

    import flash.events.MouseEvent;

    import flash.display.MovieClip;

    import flash.events.Event;

    import flash.events.*;

    import flash.media.Sound;

    import flash.events.TimerEvent;

    import flash.media.SoundChannel;

    import flash.media.SoundTransform;*/

    public class farm_Part1

    {

    public function randomizeF(a:Array):Array

    {

    a.shuffle();
    return a;
    }

    ///////////////////////////// change nothing below /////////////////////////////////////////

    function shuffle(a:Array)

    {

    var p:int;

    var t:*;

    var ivar:int;

    for (ivar = a.length-1; ivar>=0; ivar--)

    {

    p=Math.floor((ivar+1)*Math.random());

    t = a[ivar];

    a[ivar] = a

    ;

    a

    = t;

    }

    }

    }//randomAnimal

    }//class

    }//package

    var tstArrray:Array=[1,2,3];

    tstArray.shuffle();

    now, loop through your shuffled array from index 0 to its end.

    ///////////////////////////// change nothing below /////////////////////////////////////////

    function shuffle(a:Array) {

        var p:int;

        var t:*;

        var ivar:int;

        for (ivar = a.length-1; ivar>=0; ivar--) {

            p=Math.floor((ivar+1)*Math.random());

            t = a[ivar];

            a[ivar] = a

    ;

            a

    = t;

        }

    }

    /////////////////////////////////////////////////

    hey man, thx for the fast reply.

    i get this error:

    TypeError: Error #1006: shuffle is not a function.

    in using the code inside a class in a public function could that be the problem?

    thx

    the function shuffle() needs to be in the scope where it's called.
