A component that manages the process of a new host taking over a game when the old host is lost. This is referred to as "host migration". The migration manager sends information about each peer in the game to all the clients, and when the host is lost because of a crash or network outage, the clients are able to choose a new host, and continue the game.
The old host is able to rejoin the new game on the new host.
The state of SyncVars and SyncLists on all objects with NetworkIdentities in the scene is maintained during a host migration. This also applies to custom serialized data for objects.
All of the player objects in the game are disabled when the host is lost. Then, when the other clients rejoin the new game on the new host, the corresponding players for those clients are re-enabled on the host, and respawned on the other clients. No player state data is lost during a host migration.
This class provides a simple default UI for controlling the behaviour when the host is lost. The UI can be disabled with the showGUI property. There are a number of virtual functions that can be implemented to customize the behaviour of host migration.
Note that only data that is available to clients will be preserved during a host migration. If there is data that is only on the server, then it will not be available to the client that becomes the new host. This means data on the host that is not in SyncVars or SyncLists will not be available after a host migration.
The callback function OnStartServer is invoked for all networked objects when the client becomes a new host.
On the new host, the NetworkMigrationManager uses the function NetworkServer.BecomeNewHost() to construct a networked server scene from the state in the current ClientScene.
The peers in a game with host migration enabled are identified by their connectionId on the server. When a client reconnects to the new host of a game, this connectionId is passed to the new host so that it can match this client with the client that was connected to the old host. This Id is set on the ClientScene as the "reconnectId".
The old host of the game, the one that crashed or lost its network connection, can also reconnect to the new game as a client. This client uses the special ReconnectId of ClientScene.ReconnectIdHost (which is zero).
