Getting duplicate item from range of random numbers

1

hi everyone,

Im trying to create a list random numbers from 1-30 but only 10 will appear. but i also need to make sure that the list of random numbers will not have duplicates (eg 1,1,20,14,3,28,4,1,18,21). I had the thought of using an array to store the list of numbers but im stuck with how to properly use an if…then to check if the same number has already appeared.

Sorry if this was asked before but im just really confused with how to extract the contents of the array and see if one of them already appeared. I’ve attached the code so anyone can see what went wrong with it.

Anyone’s help is greatly appreciated. Thanks everyone!

function randRange(min:Number, max:Number):Number {
 var randomNum:Number = Math.floor(Math.random()*(max-min+1))+min;
 return randomNum;
}
 
var myArray:Array = new Array();
 
for (var i = 0; i<9; i++) {
 var n:Number = randRange(1, 30);
 trace(n);
 myArray.push(n);
 for (var j = 0; j<myArray.length; j++) {
  if (myArray[j] == n) {
   myArray.pop();
   var n:Number = randRange(1, 30);
  }
  trace(">> "+myArray[j]);
 }
}
