- Protocol Design
-
- Client sends a login message
- Server replies with client's position in the world and positions of
- oall other logged in players
- Merver sends player ids along with locations
- This means a newly logged in client will need to know which id is
- assigned to it
- So server needs to send an id message, wait for an ack, and then send
- the location messages
- When a client shuts down, it sends a message to indicate this so the
- server can remove it from the list of connected clients
- Eventually, there'll need to be a way to detect timeouts from clients
- (if they crashed or otherwise failed to send the logout message)
