## What it is
tolua# is a Unity Lua static binding solution that uses reflection-based code analysis to automatically generate wrapper classes for calling C# and Unity APIs from Lua. It maps C# constants, variables, functions, properties, classes, and enums into Lua with minimal GC overhead.

## Use cases
- bind C# code to Lua in a Unity game
- script Unity game logic in Lua
- generate Lua binding wrappers for Unity APIs
- hot-update game logic via Lua scripts
- call Unity engine classes from Lua without reflection at runtime

## When to choose
- you need fast, low-GC Lua interop in Unity
- you want automatic binding code generation instead of manual wrappers
- you need broad Unity type support including delegates, events, enums, and coroutines

## When to avoid
- your project targets Unity versions beyond 5.x without testing
- you prefer a reflection-based dynamic binding like ulua
- you need a maintained solution with recent Unity support

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, plugin-system, interpreter
- domain: programming-languages, developer-tools
- platform: game-engine, dotnet, lua, cross-platform
- tags: unity, lua-binding, luajit, static-binding, code-generation, game-scripting, game-development
