Extension for using the Lua programming language in Godot 4.5+

With this addon, you can program your game or application directly in Lua. You can also create sandboxed Lua states for external modding/scripting support, as many as necessary.

Features

• Create Godot scripts directly in Lua, making it possible to use Lua as an alternative to GDScript or C#
• Create additional Lua states for external modding/scripting support, as many as necessary
• Manage Lua tables, functions and coroutines directly from GDScript, C# or any other scripting language in Godot
• Select which Lua libraries and Godot APIs will be available per Lua state, making sandboxing easier:
  • Lua libraries are the same as Lua/C, like base, package and io libraries
  • Godot APIs:
    • Create and manipulate Variant values
    • Instantiate objects and access class constants
    • Access singleton objects by name
    • Global utility functions, like Godot's print_rich, lerp and is_same. Also adds an await function that mimics GDScript's await keyword (only supported when running in a coroutine).
    • Global enums, like OK, TYPE_STRING and SIDE_LEFT
    • Patch Lua package.searchers, require, loadfile and dofile to accept paths relative to res:// and user://
• Editor plugin with Lua REPL for testing out Lua snippets
• Choose between Lua 5.4 or LuaJIT v2.1 runtimes (distributed as separate addons)
  • Note: LuaJIT does not support WebAssebly, so Lua 5.4 is always used in Web platform
