Dungeon Rendering

Since generating dungeons in Unity seems to work just fine, I started working on rendering the dungeon.

First, I added random colored lights, so each room would have its own feeling to it:

The next thing I added was a basic character controller (the model is still a placeholder), so that I could walk around and see how everything looks.

I put in some walls and rendered it from an orthographic camera in 3D:

At this point, you would be able to look into every room, even if its not in your line of sight. This is very boring from a gameplay perspective and it looks very strange, too. So I quickly programmed a "fog of war"-like visibility system. Due to the fact that this is just a test, I currently use ray casting for this. This will be replaced by a much more efficient approach later on.

This little video shows everything I mentioned so far:

I also started adding more parameters and randomness to the level generator to make the levels more interesting. Writing code to create random dungeons is not very hard, but doing so that you get predictable and consistent yet interesting results isn't that easy.
