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.

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.

Prerequisites

Ungine relies on a C++ compiler and specific dependencies for its runtime and features.
