How do I make periodic expressions?

I'm looking to make a loop and spawn objects in a couple of rows and columns in that loop with a system->create object action. I'd like to avoid using a counter variable when I already have loopindex to work with.

So this successfully increases the Y coordinate every 3 spawns:

190*(round((loopindex-1)/3))

Now how do I make X to increase 3 times and then go back to zero or 1?

It should be different than the one for Y because Y stays the same for every 3 spawns, then increases. X should increase every spawn and then go back.

Thanks!

You could use the Modulo (remainder after division) expression,

0 % 4 = 0

1 % 4 = 1

.... 3 % 4 = 3

4 % 4 = 0

5 % 4 = 1 etc etc.
