These are the basic networking protocols used by the client and server
programs.
This page details the _current_ working version, it omits planned features.
#### Packet Types
* none "problem"
The declaration of this list can be found in
[packet_type.hpp](packet_type.hpp).
* ping "are you there?"
* pong "I am here"
* broadcast request "what servers are available?"
* broadcast response "I am available"
* join request "can I play? here's my data"
* join confirm "yes, here's your data"
* disconnect "I/you need to go"
* synchronize "send me all of the data you've got"
* player new "create this player at this location"
* player delete "delete this player"
* player move "this is the player's new movement data"
```

#### Procedures
connecting to a server:
Connecting to and disconnecting from a server:
* client sends a broadcast
* server responds with data (name, version)
* client sends a join request
* server responds with data (player index, resource list)
* client switches to resource loading/game mode
* client sends sync request
1. The client enters the Lobby scene and sends a BroadcastRequest
2. The server responds with a BroadcastResponse (including the server's name)
3. The client selects a server from the list of responses and sends a
JoinRequest to that server
4. The server either ignores the request, or adds the client to it's internal
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.
in the game:
* either sends player new command
* either receives player new command; server relays this command
* either sends player delete command
* either receives player delete command; server relays this command
* either sends player move command
* either receives player move command; server relays this command
