User:Jaxad0127/State machine

This article describes the internal state machines used in the client.

The core state machine is rather simple:

            -> Exit <-
            |        |
Start -> Login <-> Game
     \     v      /
      -> Error <--

Both Login and Game are sub machines.

The Login machine is more complicated. All states can go to Error, all but Start can go to Exit.
