I'm sure this isn't needed by now, just thought I'd take it as a fun
challenge.
var rangeMin:int = 0;
var rangeMax:int = 100;
var rangeSample:int = 10;
// copy
var numbers:Array = [];
// original values
var numberList:Array = [];
for ( var i:int = 0; i <= (rangeMax - rangeMin); i++ ) numberList[ i ] =
rangeMin + i;
function getRandomArray( len:int ):Array
{
// reset copy when needed
if ( numbers.length < len ) numbers = [].concat(numberList);
// transfer random values to new array
var array:Array = [];
for ( var i:int = 0; i < len; i++ ) array [ i ] = numbers.splice(
int( Math.random() * numbers.length), 1 );
return array;
}
for ( i = 0; i < 20; i++ ) trace( i + ": " + getRandomArray( rangeSample )
);
