chess-opengl

Fully functional chess game written using C and OpenGL with minimal external libraries.

DISCLAIMER: This project was created for fun and to explore OpenGL, so the code can definitely be improved / optimized further.

• Supports all the main chess rules, including castling, promotion and En Passant.
• Play with 2 people on the same device.
• Interact with pieces by clicking or dragging.
• Piece movement animations

Building:

Prerequisites:

• Windows: MSYS2/MinGW toolchain (tested). Pre-compiled libraries are provided in /lib for MSYS2 UCRT64 environment.
• Linux: System packages required:
  • libfreetype-dev (or freetype2-devel)
  • libglew-dev (or glew-devel)
  • libglfw3-dev (or glfw-devel)
  • Standard build tools (gcc, make)

Build Instructions:

• Clone this repository

git clone https://github.com/roh1th-s/chess-opengl.git
cd chess-opengl

• Build the project using make

make

• Run

"./build/chess"

Directory structure:

• /src : Contains the main source code:

  • /ui : UI components
  • /gfx : Graphics rendering code
  • /chess : Main game logic lives here.
  • main.c : Entry point

• /res : Contains project resources (fonts, shaders, textures)

To-do:

• Improve build system to support more platforms.
• Make UI system more flexible, remove hardcoded positions/sizes.
• Implement an AI to play against.
