raycaster

A simple c++ raycaster (DOOM/Wolfenstein) style

I still need to clean up the code a bit, but the map generation and raycasting all works. I also kind of wanted to add textures and maybe the ability to make your own lightsources but this all comes after code cleanup :) I'll probably post a little blurb about how the math works as well.

Here's what it looks like:

TODO (in no particular order)

• Add explanation to README
• Add texture loading
• Clean code and segment
• Add minimap to show 2D representation
• Shading (I realized I don't need light sources? It's a 2D map so I can just calculate the depth)
• Load maps from text file
• Multiple lightsources
