Question How Complex Can We Make Rule Tiles?

I'm working on a game that I'd like to use rule tiles as part of my dungeon generation. I've been playing around them for about a day or so, and I can get close to my goal, but never all the way there. So I'm wondering if I can do what I'm trying to do without custom scripting. I'm not opposed to writing some code to accomplish my goals, I just don't want to do it if it's already built into the tool. I'd like to make a rule tile that can paint a dungeon's floor and walls. If you are wondering why I don't use multiple rule tiles, it's because I'm trying to make the dungeons procedurally generated, and being able to use a single rule tile would make the process a lot easier.

For example, do something like this with a single rule tile:

 

yes but it will be harder than just making the dungeon generator just use the 2nd tile for walls

 

I think this should be relatively easy to do with a Rule Tile, by using the Extended Neighbor option.



You could set up rules along the lines of...
no tile above = a
only 1 tile above = b
only 2 tiles above = c
...
any more than 4 tiles above = e



I haven't actually done this, and it sounds time consuming, and I don't think you could have the gap in the middle (make that a different grid layered ontop?). But it should work.

 

Cool, thank you! I'll play around with it, and see what I come up with.
