cub3D

Wolfenstein 3D inspired Raycasting project

The goal of cub3d is to make something using raycasting (like Wolfenstein 3D).

How to run it on linux and macOS ?

When you clone the files, by default the linux version of the MLX library is included. If you want to run it on macOS, you need to download the macOS version of MLX and place it in the srcs/library/ file path. then just type "make linux" or "make macos".

• WASD to move
• Left-Right directional keys to rotate camera
• ESC to quit

map

you can change the map according to the rules.

• NO, SO, WE, EA texture of the direction of the wall.
• C, F is ceiling and floor rgb colors.

When creating the rays using the DDA algorithm and mlx_put_pixel, for each step I divided the current position of the ray by 64 and checked if there is 1 (i.e. wall) in the map. If there is a wall, I subtracted the x and y coordinates of the last pixel of the line from the x and y coordinates of the character and used a simple Pythagorean theorem to store the lengths of the ray in an array.
