I'm bad at explaining this so I made a quick mockup picture.
Basically what I want to happen is that since I'm using the flat tiles with no decorations to build my map. I would like to create few tiles with random decorations, as you can see i quickly made with paint for the picture. And when the layout starts for every tile there is a say 1/10 chance to change into a random tile that is the same spot but has decoration on it. You know to make the game look a bit more randomized and not just a big blank box.
Is this possible to do with C2?
something like this:
on layout start if tile is "1"
change tile to: "choose (1,1,1,1,1,1,1,1,1,2)"
