nodepp-Ungine: The Universal Nodepp Game Engine

Ungine is a high-performance, open-source game engine designed to simplify game development across 2D, 3D, and Virtual Reality platforms. Built on the speed of C++, Ungine leverages a modern node-based architecture and an asynchronous event system to help developers create stable, scalable, and complex games with minimal boilerplate code.

💡 Featured Project: Duck Hunt VR (WASM Edition)

To showcase Nodepp for Web, we ported the classic Duck Hunt to Virtual Reality, running natively in the browser via WebAssembly. This project pushes the limits of web-based VR by combining low-level C++ performance with modern Web APIs.

💡 Featured Project: Cursed-Luna (WASM Remake)

Cursed-Luna is a high-performance remake of the Global Game Jam 2018 classic. Originally built around the theme of Transmission, this version has been completely rewritten in C++ using Nodepp and Raylib to bring tight gameplay mechanics to the browser via WebAssembly.

Key Features

Performance & Architecture

• Built on C++: Harness the raw speed and efficiency of C++ for demanding applications, ensuring high frame rates and quick loading times.
• Asynchronous Core: Utilizes an internal Event Loop for efficient task management, enabling highly concurrent and non-blocking I/O.
• Node-Based Scene Graph: Every game object—from players and bombs to cameras and scenes—is a node_t, allowing for clear, hierarchical organization and easy inheritance of properties.
• Smart Memory Management: Employs a Smart Pointer Garbage Collector system to drastically reduce memory leaks and simplify resource handling compared to traditional C++.

Developer Experience

Familiar Scripting Style: The architecture offers a syntax and structure that is easy to learn for developers coming from environments like Node.js or similar high-level languages.

• Built-in Utility: Includes essential tools such as a JSON parser/stringify system and a powerful RegExp engine.
• Lifecycle Hooks: Clear object lifecycle management through powerful callbacks:
• onLoop(float delta): For frame-by-frame physics and game logic updates.
• on2DDraw(): For 2D rendering and drawing operations.
• on3DDraw(): For 3D rendering and drawing operations.
• onUIDraw(): For UI rendering and drawing operations.
• onClose(): For clean-up and resource deallocation.
