Funny story, this is my fourth attempt at making a trifiller. while I was making it, there was something off with the y-position loop. I started to drag off some extra code to delete but my finger slipped which miraculously replaced the code in the y-position calculations and everything started working. don't bother crediting me. Just use someone else's trifiller. I guarantee that theirs will be better.
