WebHowever, I really only need a single byte for each number. If I could find a way to do this, the minimum data is literally cut to an EIGHTH of what I needed before: 33 bytes or 264 bits per tile, and around 40KB for a whole level. Of course, this would only work if I have a way to take the tile data and set it to a smaller data type 6 20 comments http://marvin.cs.uidaho.edu/Teaching/CS475/bitOps.html
