    此产品包含一款代码插件,含有预编译的二进制文件以及与虚幻引擎集成的所有源代码,能够安装到您选择的引擎版本中,并根据每个项目的需求启动。 is a performant real-time bi-directional communication library. There are two parts, the server typically written in node.js and the client often in javascript for the web. There are alternative client implementations and this plugin uses the C++11 client library ported to Unreal Engine.

The plugin enables very easy real-time communications to web sites and services, phones, IoT devices, and other Unreal Engine instances. Want to enable chat with websites, phones, or other unreal games? Want to stream large data in or out of your projects? Want to control your arduino LED lights with light properties inside the engine? this plugin enables those use cases and more in a developer focused package.

Simply add a SocketIOClient component to your actor of choice and it will auto-connect to your endpoint of choice on beginplay (or at own time if desired). Then you can emit and receive events from your server directly into Blueprint structs and types you define. Check out the example chat project for a use case example.
