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
