Multiplayer Framework

The multiplayer framework that the Multiplayer Gem provides is built on top of AzNetworking. The Multiplayer Gem supports entity-based asynchronous networking in Open 3D Engine (O3DE), using event-driven network properties and remote procedure calls to synchronize O3DE components and entities across a network, giving you tools to make a multiplayer game.

The Multiplayer Gem supports the following:

  • Server authoritative networking model
  • Player spawners
  • Entity replication
  • Push-based synchronization
  • Event-driven network properties
  • Reliable and unreliable remote procedure calls
  • Local prediction
  • Network input handlers
