🎮 Cub3D

A simplified 3D game engine using raycasting – inspired by Wolfenstein 3D Built from scratch in C using MiniLibX

---

🚀 Features

• 🧭 First-person 3D perspective based on raycasting
• 🔲 Wall rendering using DDA (Digital Differential Analysis) algorithm
• 🎨 Texture mapping on walls (North, South, East, West)
• ⬆️ Ceiling and floor color rendering
• 👣 Player movement (WASD) & rotation (← →)
• 🗺️ Map parsing from .cub file (custom format)
• 📦 Robust input validation and error handling

---

🧰 Technologies & Tools

• C Language
• MiniLibX (Graphics library provided by 42)
• Raycasting for 3D projection
• Math: Vectors, trigonometry, and linear interpolation
• Makefile for building

---

🗺️ Map Format

Each .cub file includes:

• Texture paths for all four directions

• RGB colors for ceiling and floor

• 2D grid map with walls (1), space (0), and player start position (N, S, E, W)

Example:

NO ./textures/wall_north.xpm
SO ./textures/wall_south.xpm
WE ./textures/wall_west.xpm
EA ./textures/wall_east.xpm
F 220,100,0
C 225,30,0
