GDWeave

GDWeave is an experimental runtime patching system for compiled GDScript bytecode. It currently targets Godot 3.5.2 (for the game WEBFISHING).

Installation

Download the latest release and extract it to your game install. You should end up with a GDWeave folder and winmm.dll next to the game files.

After GDWeave is installed, you can install/create some mods!

Troubleshooting/tips

Do not download GDWeave from the "Code" button at the top.
You can open the folder the game is installed into with Steam - right click > "Manage" > "Browse local files".
You may need to install .NET 8 manually, if the installer from GDWeave doesn't work. Pick the SDK for Windows x64.
Linux users will need to set WINEDLLOVERRIDES="winmm=n,b" %command% in their Steam launch arguments.

Why?

GDScript Mod Loader is bad:

If your target game doesn't have the mod loader integrated, you must add it yourself. This involves decompiling the game, inserting their own code into the project, rebuilding it, and using that built copy.
Asset and build sharing is legally questionable, so non-technical users must go through this process.
Advanced patching is not possible with script extensions.

Games shouldn't need to be fully decompiled into project files to be modded, and game developers shouldn't need to be concerned with their modding community. Several modding communities already acknowledge this. So why can't Godot?

How?

GDWeave uses a Rust proxy DLL to start a C# library in the target game's address space, then hooks functions in the Godot engine itself. It then parses the GDScript "bytecode" (really a syntax tree) and runs its own processors over it, rebuilding it in place.
