This repo is no longer in development, please use the officially supported godot-dotnet repo.
The goal for this repo is to allow developers to write GDExtension with C#/.Net 8.
By leveraging the power of NativeAOT, the C# project can be compiled into an unmanaged library and expose C-style function entries, allowing the GDExtension system access.
GDExtensionSharp = Striped Down Version of GodotShap (API/HighLevel) + SourceGenerated C# Classes (from extension_api.json) + Godot GDExtension System (Interop Layer)
This project uses the GodotSharp as its high-level API, and uses GDExtension System as its interop layer.
The developer should still be working with the familiar GodotSharp Styled API as we copied most of the source code from there and programmed our source generator in a way for it to produce similar code from extension_api.json, however, since we are replacing the interop layer from godot-mono (the builtin godot mono module) to GDExtension system, we need to either find a replacement in GDExtension API or write extra interop code to achieve same functionality. In addition, we need to find another way to support data serialization while the GDExtension plugin is unloading.
The planned example project aims to replicate the well-known Dodge the Creeps Godot demo and, hopefully, be 100% source code compatible with the original version.
This project contains all the Interop Code and the source code from GodotSharp. Planned to ship as a Nuget package for .Net developer consumption.
This source generator project is responsible for converting extension_api.json to C# source code into GDExtensionSharp.csproj.
This source generator project is responsible for converting gdextension_interface.h to C# source code into GDExtensionSharp.csproj.
This source generator project is responsible for creating bridge C# source code between the original Godot.NativeInterop.NativeFunc and the GDExtension interfaces inside GDExtensionSharp.GDExtensionSharpBinding.MethodTable into GDExtensionSharp.csproj.
This source generator project is planned to ship with GDExtensionSharp.csproj for generating GDExtension Initialization Entry and ClassDB Registration Code.
