Python 3D Raycaster

A Raycaster made in Python and Pygame with minimal modules,

---

Hey fellow developers!

I've created a 'simple' 3d raycaster.
So far it needs some more work, there's features that could be added, but mostly I just wanted to get the concept working.

So far, it seems a lot faster than otehr examples I've seen. :)

1.2.

##How it works Reference: http://lodev.org/cgtutor/raycasting.html

##Note This only works for Python 3.*! (Could be converted)

##Features that could be added in the future:

• Textures.
• Sprites.
• HUD.

##Bugs:

• FishEye (groan).
• Rays seems to bend, not easily noticable.

##Problems

• My system for ray movement is very clunky. It uses steps, I may change this to use grid intersection.

#Installation The installation is very easy, if you already have Python and Pygame installed.

---

• Run 'python main.py' in cmd or for linux run python3 main.py (Not sure for Mac)

---

Otherwise if you don't have python and/or pygame, follow these steps:

• Download python 3.* from: https://www.python.org/
• Run command 'pip install pygame‑1.9.2a0‑cp34‑none‑win_amd64.whl' in cmd, same for linux (I think. Again not sure for Mac)

##In the Code Let's go through some variables,

w,h = [INT],[INT] (Screen resolution, Width and Height)
[...]
DEBUG = [BOOL] (Shows the Minimap,Rays and Player)
[...]
numRays = [INT] (Number of rays to shoot)
fov = [FLOAT] (Field Of View)

rayLength = [FLOAT] (How far each ray travels each step)
rayStep = [INT] (How many steps to take)

Thank you for reading this, I hope you find a use for this project.
Any help appreciated.
