Cub3D

Cub3D is a small 3D game engine developed as part of the 42 curriculum.
The goal of the project is to create a basic first-person view using a raycasting algorithm, inspired by early 3D games like Wolfenstein 3D.

---

Gameplay

Basic gameplay showing player movement and the raycasting rendering.

---

Custom Wall Textures

Cub3D allows the use of different wall textures.
Below is an example using an alternative texture set.

---

Direction-Based Textures & Sky Color

Each wall direction (North, South, East, West) can have its own texture.
The ceiling and floor colors can also be customized through the .cub configuration file.

---

Features

• Raycasting-based rendering
• Textured walls
• Keyboard movement and camera rotation
• Custom .cub map parsing
• Wall collision detection
• Configurable floor and ceiling colors
• Player spawn and orientation

---

Controls

Key	Action
W	Move forward
S	Move backward
A	Move left
D	Move right
← / →	Rotate camera
ESC	Exit game

Installation

Clone the repository:

git clone https://github.com/username/cub3d.git
cd cub3d

Compile the project:

make

Run the program:

./cub3D maps/map.cub

---

Map Format

The program uses .cub configuration files to define textures, colors, and the map layout.

Example:

NO ./textures/north.xpm
SO ./textures/south.xpm
WE ./textures/west.xpm
EA ./textures/east.xpm

F 220,100,0
C 225,30,0

111111
100001
10N001
100001
111111

Map Rules

• The map must be surrounded by walls (1)
• Player position is defined by:
  • N
  • S
  • E
  • W
• 0 represents empty space
• 1 represents walls
