The map is going to be generated like a typical bounded 2D maze, except I'm going to open the outer walls up for passage-carving as well, so it'll be able to loop around like it's supposed to. Once every cell has been "touched" I'll run through and remove a certain amount of walls randomly. After that, I'll pass over the result and create wall Entities for each cell, and place them accordingly.
The internal format I'll use to generate the map will be a 2D array of ints, each starting with a value of 3. I'm making each cell responsible for its left and top wall, which lets the cells tile without any extra information or overlap. 0 means no walls, 1 means left wall, and 2 means top wall. Obviously, 3 means both walls. As the generation algorithm progresses, it'll subtract a number from each cell to represent the carving out of the corridors. And after it's done, it shouldn't be very hard to ManufactureEntity("HorizWall"), ManufactureEntity("VertWall"), and ManufactureEntity("CornerWall") (for where walls meet).
Unlike most of my other plans, I put a fair amount of thought into this, and I really like how it sounds. The idea I had before about making the walls Entities, I really like that one. :) We'll see how it goes!
