hxgodot-cpp

Integrate Haxe and its hxcpp target runtime via the Godot 4.x GDExtension into Godot 4.x.

What?

There always was interest from the Haxe community and I think it would be great it can work with Godot, but somehow it never materialized into anything. - Godot's Project Lead Juan: https://twitter.com/reduzio/status/1548236136551632900

Let's make this work.

This is an early (pre-alpha) Haxe-hxcpp project that builds a dynamic library that can be loaded by Godot 4.x.

Goal

The goal is to evolve this project into a full library that allows writing extensions and new nodes in Haxe and eventually allow for cppia-scripting.

Getting started

1. Check out and build the Godot master(debug+tools) to have a working Godot 4.x Editor.
2. Then clone this repository and init the godot-headers submodule: git submodule update --init --recursive
3. Build the library: make debug. This will build a dll into test/demo/bin
4. Open your Godot4 editor and load the project that's located in test/demo.
5. The project will load a demo project and in the scene inspector you will find a node called Example that instantiates the included Haxe-class src/HxExample.hx

Debugging

• Windows: Startup your VisualStudio and setup it up to launch your compile Godot 4.x executable with the test-project defined on the cmdline. You should be able to step through the code on both sides(godot & hxgodot) and see what's going on.

What's missing

• Macros: The HxExample class is a testbed/proof-of-concept for getting the gdnative-interface and godot integration working. It loosely follows the https://github.com/godotengine/godot-cpp binding to get the ball rolling. It should serve as a base for a Haxe-Macro implementation that wraps all the classes found in godot_headers/extension_api.json.
• All binding mechanisms for (static)methods, properties, virtuals, etc
• Works & Tested only on Windows atm. But tweaking things to work under linux should be easy.
• Cppia Scripting: Once the gdnative_interface has been explored this could/should be added.
