Hello can anyone help, I'm trying to cycle through an array sequentially, but from a random index.

ie. if index 8 is picked by random then it would go 9, 10, 11 etc..

Ideally I need a setInterval between moving to the next index!

Cheers, P

Hi there,

I'll post three blocks of code, one shows how to find random startindex, the second shows the setInterval-code, and the third contains the actual function :) Look below!

Good luck!
Kindly,
Samuel
/// Array used for testing
var aArray :Array = new Array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k");
 
/// #1 Random Initiater
var iRandomNum = Math.floor(Math.random() * aArray.length); // Finds random index from aArray;
 
/// #2 setInterval
var iIntervalID;
var iIntervalTime :Number = 200; // 200 milliseconds between each trigger
 
iInterval = setInterval(doFunction, iIntervalTime);
 
/// #3 The actual function;
function doFunction()
{
	// Place code here
	trace(aArray[iRandomNum++]);
	
	// Code to end interval when it has looped through the entire interval
	if (iRandomNum >= aArray.length) {
		clearInterval(iInterval);
	}
}
