2.5D Raycast Engine for the 2D Gosu engine
The makefile is kind of basic, you'll need to make sure you include and can link in Gosu's c++ library for it to work (https://www.libgosu.org)
Bindings to ruby would be cool too but I don't have time at the moment ;P
Many thanks to Lode (http://lodev.org/cgtutor/index.html) for the incredible raycasting tutorials I referenced!
All of the raycasting code is distributed under the MIT license, so enjoy!
