I am working in ActionScript 2. I want to create a quiz in which 10 questions
are randomly selected from a block of 40 questions. I found the following code,
but I can't work out how to stop it doubling up the questions.
function randRange(min:Number, max:Number):Number {
var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNum;
}
for (var i = 0; i < 10; i++) {
var n:Number = randRange(1, 40)
trace(n);
}
When I run this it outputs a list of numbers like 40 13 17 12 27 12 3 17
9 15 which means some questions (in this case 17 and 12) will appear twice in
my quiz.
Bearing in mind that I am a bit of an ActionScript dummy, can anybody suggest a
way to modify the above script to prevent the same number being generated more
than once.
