| peers | The set of peers in the game. |
A virtual function that is called when the set of peers in the game changes.
This happens when a new client connects to the host, a client disconnects from the host, and when players are added and removed from clients.
The list of peers is stored in the member variable peers on the migration manager. This is used when the connection to the host is lost, to choose the new host and to re-add player objects.
