cub3D

A Wolfenstein 3D–style first-person raycasting engine written from scratch in C with the MiniLibX graphics library. Project of the 42 Common Core, built in a team of two: SimoneFelici and EdoardoForte.

Features

• Raycasting renderer based on the DDA algorithm, with textured walls and floor/ceiling colors
• Robust .cub parser: textures, RGB colors, map validation (closed walls, single player, valid characters)
• Smooth movement and rotation, wall collisions
• Bonus: interactive doors, minimap, HUD and mouse look
• No memory leaks: every resource is freed on exit or error

Build & run

Requires Linux with X11 development libraries (libx11-dev, libxext-dev, zlib1g-dev).

make            # mandatory part
make bonus      # doors, minimap, HUD, mouse
./cub3D maps/good/dungeon.cub

Controls

Key	Action
W A S D	Move
← → / mouse	Rotate the camera
E	Open / close a door (bonus)
ESC	Quit

What I learned

Raycasting math, fixed-step DDA traversal, texture mapping, event-driven rendering loops, and splitting a large C codebase into a clean parser / engine architecture with a teammate.
