A plugin for Unreal Engine 4 that enables game development using the Haxe programming language with full C++ API access.
Unreal.hx is a plugin for Unreal Engine 4 that enables developers to write game code in the Haxe programming language instead of C++. It compiles Haxe directly to C++ for high performance while providing full access to Unreal's API, including UCLASS creation and Blueprint integration. This allows game developers to leverage Haxe's modern features like strict type safety, garbage collection, and macros within the Unreal ecosystem.
Unreal Engine 4 developers who want to use a modern, high-level programming language with strong type safety and faster iteration cycles while maintaining full engine compatibility. It's particularly useful for teams familiar with Haxe or seeking alternatives to C++ for game logic.
Developers choose Unreal.hx because it combines the performance of C++ with the productivity and safety of Haxe, offering features like garbage collection, powerful macros, and fast compilation via cppia while maintaining seamless integration with Unreal's existing tools and workflows.

Haxe code compiles directly to C++, ensuring high runtime performance critical for games, as highlighted in the README's main features.
Provides complete access to Unreal's C++ API, including delegates and lambdas, allowing seamless use of all engine capabilities without limitations.
Utilizes hxcpp's cppia virtual machine for very fast compilation during development, enabling rapid iteration as described in the wiki for faster compiler iteration.
Leverages Haxe's strict type safety, garbage collection, and powerful macros to reduce bugs and improve developer productivity, as noted in the Haxe features section.
Supports only Unreal Engine 4.19 and specific Haxe versions (e.g., 3.4.x, 4.0.0-preview1), limiting compatibility with newer engines and potentially causing upgrade hurdles.
Requires installing Haxe, modifying Build.cs to extend HaxeModuleRules, and managing a separate Haxe directory, adding complexity to project initialization and maintenance.
Haxe has a smaller community compared to C++ in the Unreal space, leading to fewer resources, tutorials, and third-party libraries for troubleshooting or extensions.
