I created a GDExtension template on GitHub based on the Custom modules example in the official docs. The new GDExtensions system in Godot 4 let’s you create dynamic libraries in C++ to extend the engine. The template can be found here: https://github.com/paddy-exe/GDExtensionSummator
Looks good! Once Godot 4.0 stabilizes, we should eventually consider making this repository into an official Godot project (i.e. moving it to the godotengine GitHub organization).
This looks like an awesome starting point for GDExtensions! :smile:
