Hi there,

I need to create a function that will generate a random number, but not one that has already been generated. This script does work, but it also tells me I have an infinite loop in there, so its not working properly. Any suggestions anyone? Thanks 🙂

[AS]usedNum = new Array();

//populate the array  
for (i=1; i\<50; i++){  
usedNum\* = false;  
}

function numGen(){  
var theNum:Number = random(50)+1;  
if (!usedNum[theNum]){  
trace(theNum);  
usedNum[theNum] = true;  
} else {  
numGen();  
}

}

timer = setInterval(numGen, 1);[/AS]
