State Synchronization

Colyseus handles state synchronization automatically through its strongly-typed Schema structures.

How does it work?

• When the user successfully joins the room, they receive the full state from the server.
• At every patchRate, binary patches of the state are sent to every client (50ms by default)
• schema callbacks are triggered on client-side when applying patches coming from the server.
• onStateChange is triggered after all latest patches have been applied in the client.
• Your server-side logic may mutate the room state at any moment. Connected clients are always ensured to be in sync with the server.
