Online Beacons are Client/Server connections for sending RPCs without joining a Game Session, being perfect for sending any kind of data between two Unreal Engine instances. Here are a few examples on how to use this System (not all of them are included as built-in plugin examples):

• Calculating Ping between a Client and a Server.
• Gathering useful Server information.
• Creating Party Systems for Players.
• Creating direct Chat Systems outside of Game Sessions (Private Messaging).
• Server-side Server Password validation.

There’s no limit to the features that can be implemented using the Beacon System. However, Unreal's default Online Beacon system only supports C++, which means that you can not create Blueprints and solve the problem as you normally would. To see more about Beacons, see the Official Unreal Engine Documentation.

This plugin enables the user to create their own Online Beacons all directly in Blueprints, without the need of a single line of Code and .ini file edits.

Note: upgrading to the latest plugin version v1.1.5 with UE 5.3 and 5.4 may cause a loss of Beacon Settings (such as Net Driver, Listen Port and Timeout definitions). Retype the necessary values in the fields provided in the Plugin Project Settings window. These new settings will now be saved in a standalone .ini file for your convenience and better compatibility with other plugins like the Steam Subsystem. Please refer to the documentation for Patch Notes, Current Live Versions and more detailed information.
