GDNative Simple in Zig

This is a small example of working with the GDNative API from Zig. Ideally this would be a straightforward exercise, but a bug with the Zig compiler generates the incorrect ABI for passing small structs to C. This causes mysterious and confusing segfaults.

To solve this I made some small wrapper functions in C to handle those functions, and then I called them from zig.

Dependencies

• zig (master branch)
• Godot 3.4.4 Stable

Usage

NOTE: This has only been tested for Linux 64-bit in Godot 3.4.4 Stable. It will probably work for other platforms but you won't know until you try it.

This project uses a submodule for the godot-headers repository, so clone the repository recursively:

git clone --recursive https://github.com/desttinghim/gdnative-simple-zig
cd gdnative-simple-zig
zig build
godot

Clicking the button should show the string "Data = World from GDNative" to the screen.
