Setup

This section will guide you on how to setup WebSocket Server. If you don't plan to use C++ or WSS, you can directly start using the plugin by following the examples.

C++ (Optional)

If you plan to use the C++ API, you have to first add the WebSocketServer module to your project. To do so, open YourProject.Build.cs and add the following line in the constructor:

PrivateDependencyModuleNames.AddRange(new string[] { "WebSocketServer" });

Once it's done, you can include the C++ files:

#include "WebSocketServer.h"  // For the UWebSocketServer class.
#include "WebSocketClient.h"  // For the UWebSocket class.

WSS (Optional)

To use WSS, you have to get a certificate as well as a key file. You can generate a self-signed one for free with OpenSSL.
