🚀 Xnpp (xn++)

github.com/borgesdan/xnpp

A Modern, Cross-Platform C++ Implementation of the Microsoft XNA 4.0 Framework.

Xnpp is a high-performance game framework that brings the beloved XNA 4.0 API to the modern C++ ecosystem. Built with a focus on cross-platform compatibility and efficiency, it leverages a powerful tech stack: SDL3 for windowing and input, bgfx for agnostic graphics rendering, and miniaudio for robust sound management.

📦 Project Structure

The framework is modularized into four core components to ensure flexibility and maintainability:

• xnpp-csharp: A foundational compatibility layer. It provides C++ implementations of essential C# classes and logic found in the original XNA 4.0 source, bridging the gap between managed and native code.
• xnpp-framework: The heart of the project. A pure C++ library that replicates the XNA 4.0 API surface, allowing developers to use familiar patterns like Game, SpriteBatch, and GraphicsDevice.
• xnpp-content-pipeline: A dedicated library containing the logic for processing game assets. It handles the compilation of textures, sound effects, music, and custom data formats into optimized binary files.
• xnpp-content-cli: A powerful command-line tool built on top of the content pipeline. It automates the asset build process, making it easy to integrate into CI/CD pipelines or CMake build workflows.

🛠 Tech Stack

• Language: Modern C++ (C++20/23)
• Graphics: bgfx (DirectX, Vulkan, Metal, OpenGL)
