Multiplayer Networking

Connect players globally. Master replication, latency compensation, client-side prediction, and authoritative server architecture.

Multiplayer is the hardest challenge in game dev. This course teaches the architecture of real-time networking. You will learn the difference between Dedicated Servers and Peer-to-Peer. Master techniques to hide lag: Client-Side Prediction, Server Reconciliation, and Entity Interpolation. We utilize middleware like Mirror (Unity) or Unreal's Replication system to sync player movement and state securely. Essential for FPS, MOBA, and RTS developers.
