Extism Space Commander

A retro space shooter game that shows how you can integrate Extism into your project to make it super moddable. The project is built in Godot 4 and uses both GDScript (for the game logic) and C# (for integrating with Extism)

You can see the full demo with some explaination here: https://www.loom.com/share/4a0bd61c002641fcacc0ee3ce394db5c?sid=ef2de775-0b08-4fc1-8c93-f23bcf6e0b48

Structure

• scripts: contains the game logic
• scripts/mod_manager.cs: A C# class that's responsible for loading the mods
• assets/mods: contains compiled mods (.wasm files)
• mods: contains mod source files, they are all written in go

How to compile a mod

$ cd ./mods/shield/
$ tinygo build -target wasi -o ../../assets/mods/shield.wasm main.go

Note: for compiling the mods, you need TinyGo.
