Making a roguelike without a roguelike library is fun because I love trying to invent systems on my own, but I spent the whole day trying to solve a problem in 5 lines of code to calculate the weight of items! I made little progress in generating the map, but I had an idea of how it could be done. I also solved a problem in the map code for another game I'm making.
I'd already created some code to generate cave maps. The idea was to start with everything filled with "walls" and randomly dig from one random point to another until everything looked like a cave.
But for the tower, I need a code that generates straight maps made by architects. I have a few ideas and I'll continue tomorrow.
