UnrealEngine_Multiplayer_Plugin_Project

Project information

This is a lightweight Unreal Engine plugin located at Plugins/MultiplayerSessions that encapsulates common multiplayer session workflows so project code and blueprints do not need to interact directly with the Online Subsystem. The core of the plugin is UMultiplayerSessionsSubsystem, which exposes functions to create, find, join, start and destroy sessions while internally obtaining and using the engine's IOnlineSession interface. Session configuration (LAN vs. online, public connection count, presence, advertisement and lobby usage) is handled via FOnlineSessionSettings, and all asynchronous operations are reported back through delegate-based callbacks with proper delegate handle management to add and remove delegates safely. The plugin is designed to be easy to integrate into a menu system (examples included), supports presence and lobby-enabled backends when available, and requires a configured Online Subsystem (for example OnlineSubsystemNull for local testing or a platform-specific subsystem for real matchmaking).
