Thanks to all the suggestions re my random list problem. Particular thanks to Gerry Beauregard for this suggestion:"It's probably best just to create an Array or Vector containing numbers 1 to 40. (Vectors are only available in AS3, not sure about Array). Shuffle the array, then choose the first 10 elements......" The following method of shuffling an array works fine in AS2: var numArray:Array = new Array(); numArray = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40]; shuffle(numArray); function shuffle(arr:Array) { var i:Number; for (i in arr) { var tmp = arr[i]; var rNr:Number = Math.floor(Math.random()*arr.length); arr[i] = arr[rNr]; arr[rNr] = tmp; } }
I doubt the quality of that algorithm. If you do some tests, it probably has a bias of some sort. You have forced a sorting algorithm to act as a randomization algorithm.
I prefer to just use the hat picking algorithm instead. _______________________________________________ Flashcoders mailing list [email protected] http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
