To make rapid
development possible, I split the network communication part strictly from the game logic. After the NetServer
(hysbakstryd.network.Server
) is started, the GameInstance
(hysbakstryd.game.Game
) is spawned. After a successful connect
to the server, a new NetClient
(hysbakstryd.network.Client
) is created, it will register to the game and a new GameClient
is created. If the network connection from the client drops, it can reconnect with the same credentials to regain access to the coresponding game client. The client can disconnect / reconnect at any time without obstruct the server. At the same time, the network server is checking the filesystem if the code of the game (hysbakstryd.game.py
) has changed, and will hot reload the code in a way that no connection will be dropped.
