Help with ratio and frequency - actionscript

Question

I have the following:
package {
import flash.display.MovieClip;
public class Ratio extends MovieClip {
private var counter:Number;
private var frequency:Number;
private var ratio:String;
private var max:Number;
public function Ratio() {
ratio ="2/8";
var arr = ratio.split("/");
max = arr[1];
frequency = arr[0];
counter = 0;
addEventListener(Event.ENTER_FRAME, loop, false, 0, true);
}
private function loop(e:Event):void {
trace(counter + ": " + (counter < frequency));
counter++;
if (counter == max) {
counter = 0;
}
}
public function destroy():void {
removeEventListener(Event.ENTER_FRAME, loop);
}
}
}
This outputs something like:
0: true
1: true
2: false
3: false
0: true
1: true
2: false
3: false
But what I would actually like is:
0: true
1: false
2: true
3: false
0: true
1: false
2: true
3: false
i.e. more even dispersion (alternation)...is there a way to do this?

Answer 1

I think I may have missed the point here, but this should give the desired output:
private function loop(e:Event):void {
trace(counter + ": " + !Boolean(counter % 2));
counter++;
if (counter == max) counter = 0;
}
Update:
Although it's getting a little heavy-handed, the following creates an alternating dispersion where it is exactly possible. Everything else runs in a straight sequence. I'm no mathematician though, and I feel that it could be done better. For example this will treat 3/9 as 1,1,1,0,0,0,0,0,0, whereas a 'nicer' distribution might be 0,1,0,0,1,0,0,1,0
var ratio:String = "3/5";
var counter:int = 0;
var arr = ratio.split("/");
var frequency:int = arr[0];
var max:int = arr[1];
addEventListener(Event.ENTER_FRAME,loop);
function loop(e:Event):void {
if((max+1) / frequency == 2 || max / frequency == 2) {
trace(counter + ": " + !Boolean(counter % 2));
} else if((max-1) / frequency == 2) {
trace(counter + ": " + Boolean(counter % 2));
} else {
trace(counter < frequency);
}
counter++;
if (counter == max) removeEventListener(Event.ENTER_FRAME,loop);
}
