Learn how clients, servers, networking layers, and shared game state work together in a multiplayer Unity project.
Understand the differences between client-server and peer-to-peer multiplayer architectures and the factors to consider when choosing an approach.
Learn how multiplayer game state can be synchronized between the server and connected clients.
Understand RPCs, network variables, client-server communication, and how to decide which approach fits different gameplay data.
Learn how to design turn ownership, action validation, turn timers, disconnected-player handling, and turn-based multiplayer flows.
Explore lobby creation, joining, ready systems, private and public lobbies, matchmaking, and starting multiplayer matches.
Learn how to handle connection loss, player reconnection, state restoration, mobile network switching, and reconnect timeouts.
Understand server-authoritative game logic, action validation, invalid requests, random outcomes, score protection, and multiplayer security fundamentals.
Learn practical approaches for reducing network traffic, optimizing mobile performance, handling poor network conditions, and improving multiplayer behavior on mobile devices.
Use this checklist to test multiplayer connections, lobbies, matchmaking, turns, synchronization, reconnection, network conditions, mobile devices, and security.
The examples/ directory contains small examples related to the concepts covered in the documentation.
Example of organizing turn-based gameplay using clearly defined states and transitions.
2. Player State
Example of structuring player information such as position, score, readiness, and connection state.
Example of structuring shared multiplayer game state and synchronizing important gameplay information.
