Spent a couple of weeks away from code. Was ill for a little while, then went away for a while, far from keyboards and screens. Very relaxing.
Next things on my list for this thing:
1) Add multiple textures so I can add indicators to the terrain and use gradient filtering to allow for less crude discontinuity between cells.
2) Modify cell rendering info passed through from the lua so scripts can control the output more.
3) Add resource points to the database and add info to the map to show them.
Another thing I'm vaguely working on is a libtcod-based roguelike based on my tabletop Tales and Fables campaign.
