Unreal Engine Online Subsystem (OSS) Code

This section contains the source code of an Unreal Engine project built using the Third Person Feature Pack. The project demonstrates how to integrate the Epic Online Services Online Subsystem plugin into your game. The code corresponds to the course: The EOS Online Subsystem (OSS) Plugin.

The Unreal Engine code is structured around real-world scenarios and is up to module 7 - EOS P2P, Lobbies and Voice. Below is a table listing the modules included in the course.

Module	Release Date
Plugin Configuration	Released
Signing-in	Released
Setting up a dedicated server to host EOS Sessions	Released
Joining EOS Session	Released
EOS Stats, Achievements, and Leaderboards	Released
EOS Player and Title Data Storage	Released
EOS P2P, Lobbies, and Voice	Released
Voice on Trusted Server	TBD
Easy Anti-Cheat	TBD

Important Note

If you're working with EOS P2P, make sure to use Unreal Engine version 5.3, which includes EOS SDK version 1.16. If you are using an older version of Unreal Engine, you may need to upgrade the EOS SDK. For guidance, refer to Upgrading the EOS SDK.

Older versions of the EOS SDK may be affected by a WebRTC vulnerability.
