Note: This was my fifth 42 project, completed February 2021. It was my biggest project at the time, it involved a lot of maths to get the graphics right. I had a lot of fun adding extra features to this project, like custom textures, custom screenshots, audio, shading and a hurt system.

cub3d

This project is a graphic design project, inspired by the famous game Wolfenstein 3D. Creating a "realistic" 3D graphical representation of the inside of a maze from a 2D map, with a first person perspective using Ray-Casting principles.

Technical details

• Controls: W A S D to move, left and right arrow to change camera angle, ESC or close window to exit program
• Reads in a .cub map file, with map specifications and 2D map design, which are validated by the program before getting into gameplay
• Ceiling and floor color is read from the .cub file and can be changed
• Walls are textured, customs textures can be added and read from the .cub file
• Distance-based shading
• Added a soundtrack
• Custom cactus sprites are added, hurt triggers when walking into them
• Program exits when the player dies
• Running the program with --save as an argument takes a screenshot of the first loaded frame and saves it in the screenshot folder
• All heap allocated memory space is properly freed
• Allowed functions: open, close, read, write, malloc, free, perror, strerror, exit, all functions of the math library and the MinilibX graphic library

How to run

Run the following commands. This version of the graphic library only works with MacOS. A test map file (test.cub) is provided in the maps directory. Replace test.cub with a .cub file of your choice

$ git clone https://github.com/elbaradi/ft_cub3d
$ make bonus
$ ./cub3d maps/test.cub
