Re: [Flashcoders] Random numbers list
If you do not care if the sequences repeat, you could fill an array with
the numbers from 1 to 100 arranged in a random order.
When you want to grab 10, just pick a random integer between 0 and 89
and grab the block of 10 numbers following that point.
This would charge a penalty once when you loaded the 100 but your
refresh of the 10 would be very fast.
You could have a counter on the array of 100 and every so often (after
10-50 blocks of 10 used) regenerate the sequence of 100 if you want to
avoid repeating the same sequence.

Hi Laurent,
Your first suggestion is a very simple and clever trick i'll
definetely keep
in mind for future situations.
However for this second variation you mean that I:
1) pick the numbers out of array 1 and splice it
2) move those numbers into array 2
3) when the length of array 1 would be 10 i would start picking the
numbers
out of array 2 and do the inverse.
Is this what you mean?

Hi all!
What I am trying to figure out is this:
How to generate a sequence of random numbers where the newest is
always
different from all the previous?
I need to continuosly rewrite an array of 10 random numbers in
such a way
that at any given time they are all different.
Let's say that my range is 0 to 100
it starts with random numbers, all different:
{3, 34, 12, 69, 6, 44, 31, 90, 88, 23}
at a set interval some values are replaced by new ones so there
are never
two equal numbers, so, after 2 seconds it may look like this:
{3, 66, 12, 79, 6, 44, 10, 81, 88, 23}
Any ideas?
Thanks :)

RE: [Flashcoders] Random numbers list
yes like:
allNumbers:Array = [ 0, 1, 2, 3, ..., 100 ];
tenNumbers:Array = [];
public function getNumberIn():void{
var n:int = tenNumbers.splice( int( Math.random * 10 ), 1 );
tenNumbers.push( allNumbers.splice( int( Math.random *
allNumbers.length ), 1 ) );
allNumbers.push( n );
}
Could be like that. ;)
Make a temporary copy of the allnumbers array then splice from the copy.
AS2:
code
var allNumbers:Array = [0, 1, 2, 3, ..., 100];
var tenNumbers:Array = [38, 10, 70, 30, 63, 20, 66, 37, 16, 87];
function getNumberIn():Void{
var ca:Array = [].concat(allNumbers);
var n:Number = 10;
while(n--){
tenNumbers[n] = ca.splice(Math.floor(Math.random() *
ca.length - 1), 1);
}
trace(\ntenNumbers = +tenNumbers);
}
/code

Re: [Flashcoders] Random numbers list
No, that is not the only way you can target a path in the MAC. for example I
different projects some require to distribute the PPV classes with the
project so i add the classes inside the same folder I am working on.
/Application.as
/src/
/src/ppvclasses
Then in my application I just do:
import org.papervision3d.cameras.FreeCamera3D
But if I am just testing it doesnt matter where the classes are as long as I
target the class path properly.
If you are still having issues I would recommend to read the following

Re: [Flashcoders] Random numbers list
This is very similar to what other people have already said. Basically, you
can have two lists: one acts as a pool from where you'll grab numbers,
randomly; the other one is a sequence of unique numbers.
First, you fill the pool with numbers that fall between some range. Then you
take one of the numbers in the pool and put it in the sequence list, untill
you've filled it up.
To refresh the sequence, just pick a random index from it, replace the
value pointed by that index with a random value taken from the pool and put
the value extracted from the sequence back into the pool.
In code:
import flash.utils.Timer;
import flash.events.TimerEvent;
var uniqueSequence:Array = [];
var numbersPool:Array = [];
var maxRange:int = 100;
var minRange:int = 0;
var sequenceSize:int = 10;
function init():void {
var i:int = minRange;
while(imaxRange) {
numbersPool.push(i);
i++;
}
i = 0;
while(isequenceSize) {
uniqueSequence.push(getFromPool());
i++;
}
}
function getFromPool():int {
var idx:int = Math.round((numbersPool.length - 1 )* Math.random());
return numbersPool.splice(idx,1)[0];
}
function refresh():void {
var seqIdx:int = Math.round((sequenceSize - 1 )* Math.random());
var tmp:int = uniqueSequence[seqIdx];
uniqueSequence[seqIdx] = getFromPool();
numbersPool.push(tmp);
trace(uniqueSequence);
}
function handleTimer(evt:TimerEvent):void {
refresh();
}
init();
var timer:Timer = new Timer(250,5);
timer.addEventListener(TimerEvent.TIMER, handleTimer);
timer.start();

Re: [Flashcoders] Random numbers list
you could make a first array filled with all number from 0 to 100 and
then you splice to any random index range between 0 and the new size of
the array.
You fill another array with the last spliced number. do I make sense ?

Hi all!
What I am trying to figure out is this:
How to generate a sequence of random numbers where the newest is always
different from all the previous?
I need to continuosly rewrite an array of 10 random numbers in such a way
that at any given time they are all different.
Let's say that my range is 0 to 100
it starts with random numbers, all different:
{3, 34, 12, 69, 6, 44, 31, 90, 88, 23}
at a set interval some values are replaced by new ones so there are never
two equal numbers, so, after 2 seconds it may look like this:
{3, 66, 12, 79, 6, 44, 10, 81, 88, 23}
Any ideas?
Thanks :)

Re: [Flashcoders] Random numbers list
still it can be done like that you always keep the number of numbers
between two arrays...
and swap numbers from one to another, that your sure to neve have twice
the same one
yeah...! :]

RE: [Flashcoders] Random numbers list
Every time you generate a new random number go through the array and see if
any match the new number if so generate a new one and check again, if not
add it to the array.
With only 10 numbers in the array it would check very fast so you wouldn't
be taking a performance hit.

Re: [Flashcoders] Random numbers list
Can numbers repeat? Is this a constant loop where, for instance, the
number 12 could show up two times in twenty seconds? Or would you want
12 to show up once and then go out of circulation permanently?

Re: [Flashcoders] Random numbers list
Hi Matt,
Yes numbers can and should repeat through time. They just cant be repeated
within the sequence at a given discreet time. Makes sense? :)

Re: [Flashcoders] Random numbers list
Hi Laurent,
Your first suggestion is a very simple and clever trick i'll definetely keep
in mind for future situations.
However for this second variation you mean that I:
1) pick the numbers out of array 1 and splice it
2) move those numbers into array 2
3) when the length of array 1 would be 10 i would start picking the numbers
out of array 2 and do the inverse.
Is this what you mean?

Re: [Flashcoders] Random numbers list
Hi Steve,
That was actually my first thought. I had a while loop and inside a for ...
in loop to iterate through the array to check if the number was already
there. But then for some reason the script made flash unresponsive.
However I just came up with this which seems to be working, but i'm still
very curious to learn of better ways of achieving this:
function pickUniqueNumber():Number {
var randomNum:Number;
var loop:Boolean = true;
var numberList:String = |+currentNumbers.join(|)+|;
while (loop) {
randomNum = random(wallpaperList.length);
var numberString:String = |+randomNum+|;
if (numberList.indexOf(numberString) == -1) {
currentNumbers.push(randomNum);
loop = false;
}
}
return randomNum;
}

Re: [Flashcoders] Random numbers list
yes like:
allNumber:Array = [ 0, 1, 2, 3, ..., 100 ];
tenNumbers:Array = [];
public function getNumberIn():void{
var i:in = int( Math.random * allNumber.length );
tenNumbers.push( allNumber.splice( i, 1 ) );
}
then I don't know how you pick up the number to pass from tenNumbers to
allNumber.

Re: [Flashcoders] Random numbers list
or perhaps tenNumber[ tenNumbers.length ] is faster than
tenNumbers.push() never know about that one...the second return
something so perhaps its slower..
