## What it is
UnLua is a highly optimized Lua scripting plugin for Unreal Engine that lets UE programmers write gameplay logic in Lua with zero learning cost. It provides direct access to UCLASS/UPROPERTY/UFUNCTION/USTRUCT/UENUM without glue code, blueprint event overriding, and engine-optimized container and struct handling.

## Use cases
- script unreal engine gameplay logic in lua
- override blueprint events and functions with lua
- hot-update game logic without rebuilding the engine
- bind input and replication events from lua
- call latent functions from lua coroutines
- expose custom c++ classes and enums to lua

## When to choose
- you need a mature, Tencent-backed Lua scripting solution for UE 4.17 through UE 5
- you want zero-glue-code access to Unreal reflection types from Lua
- you need high-performance Lua bindings with optimized parameter passing and native container access

## When to avoid
- your project does not use Unreal Engine
- you prefer a different scripting integration like Blueprint-only or Python
- you need a plugin with a permissive license for commercial redistribution without review (license is marked NOASSERTION)
