Wave Function Collapse

Amazing work. I want to implement my own version of WFC in my rouge-like. Are the adjacency rules auto generated or predefined?

Thanks @justsomeguy! 

The adjacency rules are generated from a map that I created manually.  So, I load that map first, find all the unique tiles and then walk through each x,y position on the map and create the adjacency rules based on what I find.  This is done in the AnalyzeMap sub.

The nice thing about this approach is that you can use the same algorithm for any tileset just by creating a sample map with an editor.  Coding the adjacency rules manually would be pretty painstaking unless you had a very simplistic tileset.
