A Raycaster programmed in C by pdruart and rdrazsky for the Cub3d subject of Codam as part of the 42 network.
Made using MLX42, commit 13a181d73868fbd1ef8aee0b85c3bc0003ee4c40 with a couple changes, and thus requires GLFW to be installed.
On Mac and Linux run
make
within the project directory to compile the mandatory part.
And run make bonus to compile the bonus part.
Syntax: <executeable> <path_to_scene_file> where the executable name generated for the mandatory is cub3d and the bonus executable name is cub3d_bonus.

Every valid scene file has .cub as its extension.
A scene consists of 2 parts; Definitions and a Map, in that order.
Definitions have an identifier followed by at least 1 space and then their definition followed by a newline. Definitions can be spaced out with empty lines between them and be in any order so long as they are defined only once.
A Map is a tiled grid using characters that's always enclosed such that only walls are touching spaces/the outside. A map always has exactly 1 player spawn position.
