/* The Communications manager brokers messages between controllers It
|
|
* maps players to devices.
|
|
*
|
|
* Messages for players go through it. If the player is remote, then the
|
|
* message is queued. If local, it's a simple function call executed
|
|
* immediately. When the caller is finished, it calls comms_okToSend()
|
|
* or somesuch, and all the queued messages are combined into a single
|
|
* message for each device represented, and sent.
|
|
*
|
|
* The problem of duplicate messages: Say there are two players A and B on
|
|
* remote device D. A has just made a move {{7,6,'A'},{7,7,'T'}}. The
|
|
* server wants to tell each player about A's move. It will want to send the
|
|
* same message to every player but A, yet there's no point in sending to B's
|
|
* device since the information is already there.
|
|
*
|
|
* There are three possiblities: put message codes into classes -- e.g.
