GDLuau

A GDExtension that adds Luau C/C++ API bindings to GDScript (+ some extras)

Warning

This repository's main branch is only usable with GDExtension from Godot's master branch.

About

GDLuau is for in-game scripting / UGC / modding. (This is not a replacement for or an alternative to GDScript.)

Luau API closely follows Lua 5.1 API, you can find the manual here.
For coding in lua/luau take a look at the "Getting Started" section on luau-lang.org.

Features

• Full C/C++ API in GDScript excluding lightuserdata/userdata
• Pushing/Pulling normal Callables (lambda Callables aren't supported)
• Pushing/Pulling Objects (Node / RefCounted) (as userdata)
• Pushing/Pulling Godot Arrays and Dictionaries
• Pushing/Pulling Godot Vector4s as Luau vectors
• Custom print implementation that emits a signal
• lua_loadstring, lua_dostring in GDScript (were "missing" in Luau)
• Configurable interrupt signal for run-away scripts (while true do end)

Compiling

• Clone the repo
• Run scons platform=<platform> (also, preferably, add use_mingw=yes, if you have it installed)
• A test project is included in the repo
