## What it is
xLua is a Lua scripting solution for C# environments such as Unity, .Net, and Mono, enabling Lua code to interoperate with C# in both directions. It supports runtime hot-patching of C# methods with Lua implementations and offers GC-optimized value type passing across the Lua/C# boundary.

## Use cases
- script unity game logic in lua
- hot patch c# methods at runtime in unity
- call c# code from lua scripts
- avoid gc allocations when passing structs between lua and c#
- embed a lua interpreter in a .net application
- write unity ui and monobehaviour logic in lua

## When to choose
- you need runtime-updatable game logic or hotfixes in a Unity project without rebuilding
- you want mature, widely used Lua-C# binding with strong performance and GC optimizations
- you target multiple platforms including android, ios, windows, linux, and osx

## When to avoid
- your project does not use C#, Unity, .Net, or Mono
- you prefer statically typed scripting or a different scripting language
- you need a general-purpose standalone Lua interpreter outside a C# host

## Facets
- artifact type: library
- maturity: stable
- function: interpreter, plugin-system, concurrency
- domain: programming-languages, cross-platform
- platform: windows, cpp, c
- tags: lua, unity, unity3d, csharp, scripting, hotfix, interop, game-scripting, game-development, android, ios, linux, macos
