🎮 Cub3D - A Wolfenstein 3D-style Game Engine

🎯 Project Overview

Welcome to Cub3D, a project inspired by Wolfenstein 3D's rendering engine. Using raycasting, we transform a 2D map into an immersive 3D world, creating a dynamic view inside a maze.

🛠️ Technical Requirements

The project must follow these specifications:

• Written in C according to the Norm
• Allowed functions:
  • Basic: open, close, read, write, printf, malloc, free, perror, strerror, exit
  • Math library (-lm)
  • MinilibX library
• Libft library is allowed

🗺️ Map and Scene Description

The scene is described in a .cub file containing:

• Wall textures for each direction:
  • NO ./texture/walls/north_wall_texture.xpm
  • SO ./texture/walls/south_wall_texture.xpm
  • WE ./texture/walls/west_wall_texture.xpm
  • EA ./texture/walls/east_wall_texture.xpm
• Floor and ceiling colors (RGB format)
• Map using these characters:
  • '0' for empty spaces
  • '1' for walls
  • 'N', 'S', 'E' or 'W' for player's starting position and direction

🎨 Raycasting Implementation

📐 Core Mechanics

1. For each screen column:
   • Calculate ray direction using camera plane
   • Determine wall intersections using DDA algorithm
   • Calculate wall height based on perpendicular distance

🎥 Display Requirements

1. Texture Display:
   • Different textures for each wall direction (N, S, E, W)
   • Floor and ceiling colors
   • Proper perspective correction

🎮 Controls

👾 Basic Controls

• Movement: W, A, S, D keys
• Camera rotation: Left/Right arrow keys
• Exit: ESC key or window close button

🏃‍♂️ Window Management

• Smooth window handling (minimize, switch)
• Clean exit on window close

🚀 Getting Started

Building the Project

make        # Compile the project
make clean  # Remove object files
make fclean # Remove object files and executable
make re     # Recompile everything

Map Requirements

• Maps must be closed/surrounded by walls
• Only one player starting position
• Invalid maps should return "Error\n" with explicit message
• Spaces are valid in maps

🎨 Bonus Features

Optional enhancements:

• Wall collisions
• Minimap system
• Opening/closing doors
• Animated sprites
• Mouse-controlled camera rotation

🎯 Key Challenges & Solutions

Common issues to watch for:

• Texture alignment: Verify wall hit calculations
• Wall distortion: Ensure proper perpendicular distance calculation
• Map parsing: Handle all edge cases and spaces correctly

Remember: Focus on creating a stable 3D visualization with clean, norm-compliant code! 🎮✨
