## What it is
Slua-unreal is an Unreal Engine 4/5 plugin that lets developers write game logic in Lua instead of C++, with automatic export of blueprint and C++ interfaces to Lua. It supports hot-fixing code without recompilation and two-way communication between Lua, C++, and Blueprints.

## Use cases
- write unreal engine game logic in lua
- hot update game code without recompiling c++
- call blueprint functions from lua scripts
- override blueprint functions with lua
- profile lua cpu usage in shipped games
- wrap c++ classes for lua scripting

## When to choose
- you need fast iteration on game logic without c++ compile times
- you want to hot-fix live game code after release
- your team prefers scripting game logic in lua
- you need lua-blueprint interop in unreal engine

## When to avoid
- you are not using unreal engine
- your project requires pure c++ with no scripting layer
- you need a scripting solution for a different engine like unity or godot

## Facets
