This project is the code I was left with after I went through the breakout tutorial at LearnOpenGL. There’s a slight twist though: I did it using OCaml rather than C++. At the time, I was interested in game programming in general, but also in what good a language like OCaml could be for games, so I decided to make it a two-fold exercise. The final game is exactly the same as the C++ version at the end of the tutorial.
Trying to find natural ways to transform object-oriented code into functional code was a fun endeavor, but the biggest headache came from an unexpected place: linking to external C libraries. This is a very straightforward task in the normal course of the tutorial, but in an OCaml context it requires the additional work of binding to the C code. For some of the libraries, there was no binding already available and I had to do them myself, which turns out to be quite complicated if you want to do it the right way.
