Cub3D - raycasting game

This project is inspired by the world-famous Wolfenstein 3D game, which was the first FPS ever. It is a raycasting game, which means that it uses raycasting techniques to render a 3D environment in a 2D map.

The goal of this project is to create a dynamic view inside a maze, in which you can move around and interact with objects.

How to play

Installation

To install the game, you need to run the following commands:

Note: This project was developed on macOS, so it may not work on other operating systems, also it requires the minilibx library to run.

git clone https://github.com/bablilayoub/cub3D
cd cub3D
make all bonus clean

Running the game

To run the game, you need to run the following command:

Without bonus

./cub3D maps/map.cub

With bonus

./cub3D_bonus maps/map_bonus.cub

Controls

• W A S D to move around
• ← → to rotate the camera
• ESC to exit the game
• SPACE to open/close the doors

Map configuration

The map is configured in a .cub file, which is a text file that contains all the information needed to render the game.

Here is an example of a map configuration:

NO ./textures/wall_n.xpm
SO ./textures/wall_s.xpm
WE ./textures/wall_w.xpm
EA ./textures/wall_e.xpm

F 220,100,0
C 0,100,220

• NO, SO, WE, EA are the paths to the textures of the walls
• F is the color of the floor
• C is the color of the ceiling
• The map is composed of numbers and letters:
  • 1 is a wall
  • SPACE / TABS are empty spaces
  • 0 is an empty space (floor)
  • N, S, W, E are the player's starting position and orientation
  • D is a door

Bonus

• Wall collisions
• Sprite
• Minimap
• Doors
• Mouse rotation

Conclusion

This project was a great opportunity to learn more about raycasting techniques and game development. It was a challenging project, but it was also very rewarding to see the final result.

I hope you enjoy playing this game as much as I enjoyed creating it!
