## What it is
UE5Coro is a C++20 coroutine plugin for Unreal Engine 4 and 5 that integrates deeply with the engine's gameplay systems. It lets developers write asynchronous and latent logic with co_await, replacing callbacks and FPendingLatentAction boilerplate.

## Use cases
- write async gameplay code with coroutines in unreal engine
- create latent blueprint-callable functions without boilerplate
- await asset loading asynchronously in c++
- spread heavy computation across ticks or worker threads
- replace callback-based async code in ue5 with co_await

## When to choose
- you write C++ gameplay code in Unreal Engine 4/5 and want clean async/await syntax
- you need latent UFUNCTIONs with Blueprint-safe multithreading
- you want automatic coroutine cleanup tied to UObject lifetime

## When to avoid
- your project is Blueprint-only with no C++ code
- you target an engine version or compiler without C++20 coroutine support
- you need coroutine support outside Unreal Engine

## Facets
- artifact type: plugin

- platform: cpp, game-engine, windows
- tags: unreal-engine, coroutines, cpp20, async-await, latent-actions, blueprint, game-development, linux, macos
