After collision got working (last post) I implimented digging, and it works great animations and all.  After I got digging as done as it’ll get, I tried tackling cavern generation…and ended up with laggy strait tunnel generation.  This was another bummer because I spent so much time working on it trying to figure out a good algorythm, but it failed in the end.  I got a tiny bit a spriting done, and now I’ve turned off the screen recorder for the night and am not going to work on it anymore at the moment.  I’m going to sleep on the algorythm, and hope tomorrow will bring better luck with my not waisting my time with failedattempts.
