Hi,

first off, declare an item counter like this

var itemCounter = 0;

at the second row, then just exchange the line

var item = dots[Math.floor(dots.length * Math.random())].clone();

with this one.

var item = dots[itemCounter % dots.length].clone();
itemCounter++

Good luck!

I tried as you suggested so the script looks like this:

function createDot(x, y, dots, radius) {
if (radius > 0) {
// Pick a dot at random:
var itemCounter = 0;
var item = dots[itemCounter % dots.length].clone();
itemCounter++
item.position += new Point(x, y) * values.size;
item.rotate(radius * values.rotation * Math.PI / 180.0, item.position);
item.scale((radius * radius * values.gradiation + radius * (1.0 - values.gradiation)) * values.scale);
return item;
}
}

but it only creates the rasta half-tone image with the first object.
If I change
var itemCounter = 0;
to
var itemCounter = 1;
then it will create the half-tone image with the next object down so I understand that I am trying to increase that number for each clone. Is the code: itemCounter++ meant to increase that number by 1?

thanks

Sorry, I was a bit unclear about the counter.

The line

var itemCounter = 0;

cannot be inside the createDot-function as it will be set as 0 (zero) EVERY time that particular function is called (ie. once per object) therefore the chosen object will always be item[0].

This should work better:

var itemCounter = 0;

function createDot(x, y, dots, radius) {
	if (radius > 0) {
		var item = dots[itemCounter % dots.length].clone();
		itemCounter++
		item.position += new Point(x, y) * values.size;
		item.rotate(radius * values.rotation * Math.PI / 180.0, item.position);
		item.scale((radius * radius * values.gradiation + radius * (1.0 - values.gradiation)) * values.scale);
		return item;
	}
}

This way the itemCounter is set as zero only once (at the start of running the script), and is then increased by one with the line:

itemCounter++

Hope that helps!

That works perfectly - thanks very much. I'm going to go through the tutorials again and see if I can wrap my head around it.
