This code accompanies this course: The EOS Online Subsystem (OSS) Plugin The table below lists the module entries in this course. Unlike the Csharp code, the UE code isn't structured per tutorial, but instead structured in a way it could be done in a real game. The code currently is up to module 7 - EOS P2P, Lobbies and Voice

Important Note

If you are using EOS P2P, you should use Unreal Engine version 5.3 as it is bundled with EOS SDK 1.16. Or, you should upgrade the EOS SDK version in older version of UE, see Upgrading the EOS SDK. Older versions of the EOS SDK have this WebRTC vulnerability.
