I spent the past few hours following along to a course on Lynda that discussed how to design an random map generator with auto tiling. Overall the course was fairly simple and only uses 4 bit tile bitmask, but it certainly helped to clear the air about tile bitmasks in general as I had been reading up on them the other day and couldn’t quite wrap my head around the concept.

In the header image you can see the entirety of what was accomplished.
