Procedurally generating a dungeon

It's time to put this theory into practice and implement procedural dungeon generation in our game for real. We'll move the Level class from loading its data from a text file to generating it at runtime, and we'll also cover the application of the correct sprites to the tiles in the random level.

As we identified, one way of approaching this is to generate a maze over the entire play area and then generate rooms to carve out some larger open areas. This method not only generates tighter, more intertwined levels, but also saves us the step of having to connect mazes to rooms, leaving us with just two steps to generate great levels:

Changing how we view the maze

Before we write any code, we're going to make a change to the project so that we can easily see the entire level. Currently, the view is zoomed, and we have the light blocking the level. We want to be able to see the entire maze as we work on the algorithm. So let's make some changes.

The first thing that...
