C++ Game Engine

A high-performance 2D/3D game engine written in modern C++ with OpenGL rendering, physics simulation, and entity-component-system architecture. Built from scratch with focus on performance, modularity, and developer experience.

Features

• OpenGL Rendering - Modern OpenGL 3.3+ renderer with shader support
• Entity Component System - Flexible ECS architecture for game objects
• Physics Engine - 2D/3D physics simulation with collision detection
• Asset Management - Texture, model, and shader resource loading
• Input System - Keyboard, mouse, and gamepad input handling
• Audio System - Sound and music playback using OpenAL
• Scene Management - Scene graph and object hierarchy
• Shader Pipeline - GLSL shader compilation and management
• Cross-Platform - Windows, Linux, and macOS support

Building

Prerequisites

• C++17 compiler (GCC 7+, Clang 5+, MSVC 2017+)
• CMake 3.12+
• OpenGL 3.3+ compatible graphics card
• GLFW, GLAD, GLM (included via CMake)

Build Instructions

mkdir build && cd build
cmake ..
make  # or `cmake --build .` on Windows
./game-engine  # or `game-engine.exe` on Windows
