#### Procedures #### Procedures
connecting to a server: Connecting to and disconnecting from a server:
* client sends a broadcast 1. The client enters the Lobby scene and sends a BroadcastRequest
* server responds with data (name, version) 2. The server responds with a BroadcastResponse (including the server's name)
* client sends a join request 3. The client selects a server from the list of responses and sends a
* server responds with data (player index, resource list) JoinRequest to that server
* client switches to resource loading/game mode 4. The server either ignores the request, or adds the client to it's internal
* client sends sync request client list and responds with a JoinResponse (including the new client's index)
5. When the client receives the response, it switches from the Lobby scene to
the InWorld scene.
6. Pressing the escape key on on the client (while in the InWorld scene) will
send a Disconnect message, and will switch the client to the MainMenu scene.
7. When the server receives the Disconnect, it will send another (at this stage
redundant) Disconnect to the client, and remove it from the list of clients.
