Hiya, I am sure there is a very simple way to do this but I cant figure it out at all. I am trying to write a function that is passed an array and will then reorder it randomly and return the array. My problem is that as the position is generated randomly I dont know how long the loop must run for, this function doesn’t work but it should give you an idea of what I’m trying to do:  
[AS]  
function randomise(the\_ar:Array):Array {  
var ret\_ar:Array = new Array();  
for (i=0; i\<200; i++) {  
var randomNum:Number = Math.floor(Math.random()_(4-0+1));  
if (ret\_ar[randomNum] == undefined) {  
if (ret\_ar.length\<the\_ar.length) {  
ret\_ar[randomNum] = the\_ar_;  
} else {  
return ret\_ar;  
break  
}  
} else {  
}  
}  
}  
[/AS]  
Thanks for any help 🙂
