Why EMF?

Wiring EOS by hand means SDK handle juggling, raw C callbacks, and hours lost to include-order errors before a single player connects. EMF wraps every EOS interface in async Blueprint nodes that just work. Fill in your credentials, press one button, and ship multiplayer.

One-click setup

Paste your EOS credentials into Project Settings → Plugins → Epic Multiplayer Framework, hit Apply EMF Project Settings, restart. Every ini entry, net driver binding and platform config is written for you. You never hand-edit a config file.

Key Features

• Full lobby system ( create, search, join by ID, join by room code, invites, live member list, custom lobby & member attributes )

• Auto-travel lobbies ( host opens the map, clients follow, no manual URL wiring )

• EOS P2P networking ( custom NetDriver + socket subsystem, no dedicated server or port forwarding needed )

• Sessions ( classic advertised server browser with search filters )

• Voice chat ( EOS RTC tied to the lobby, self-mute, per-player mute, live speaking events for your UI )

• Identity ( Account Portal, Persistent Auth, Device ID (anonymous), Developer Auth Tool )

• Stats & Achievements ( ingest, query, unlock, plus Ingest Stat And Read that solves the classic "stat never shows" problem )

• Leaderboards ( global ranked boards and friends-only score queries )

• Cloud storage ( Player Data Storage and Title Storage as simple read/write string calls, chunking handled internally )

• Friends & Presence ( friends list, invites, rich presence, live update delegates )

• Easy Anti-Cheat ( client and server subsystems with message relay and integrity events )

• 36 async Blueprint nodes ( every operation is a latent node with Success / Failure pins )

• Playable demo project ( login, main menu, lobby browser and gameplay maps, fully wired )
