/***************************************************************************
* Queue_AI_Multiplayer -- Process all queued events. *
* *
* This is the network version of the queue management routine. It does *
* the following: *
* - If this is the 1st frame, waits for other systems to signal ready *
* - Generates a timing event, to allow the connection time to be dynamic *
* - Handles timing related to sending packets every 'n' frames *
* - Sends outgoing events *
* - Frame-syncs to the other systems (see below) *
* - Executes & cleans out the DoList *
* *
* The Frame-Sync'ing logic is the heart & soul of network play. It works *
* by ensuring that any system won't out-run the other system by more than *
* 'MaxAhead' frames; this in turn ensures that a packet's *
* execution frame # won't have been passed by the time that packet is *
* received by all systems. *
* *
* To achieve this, the system must keep track of all other system's *
* current frame #'s; these are stored in an array called 'their_frame[]'. *
* However, because current frame #'s are sent in FRAMEINFO packets, which *
* don't require an ACK, and command packets are sent in packets requiring *
* an ACK, it's possible for a command packet to get lost, and the next *
* frame's FRAMEINFO packet to not get lost; the other system may then *
* advance past the frame # the command is to execute on! So, to prevent *
* this, all FRAMEINFO packets include a CommandCount field. This value *
* tells the other system how many events it should have received by this *
* time. This system can therefore keep track of how many commands it's *
* actually received, and compare it to the CommandCount field, to see if *
* it's missed an event packet. The # of events we've received from each *
* system is stored in 'their_recv[]', and the # events they say they've *
* sent is stored in 'their_sent[]'. *
* *
* Thus, two conditions must be met in order to advance to the next frame: *
* - Our current frame # must be <= their_frame + MaxAhead *
* - their_recv[i] must be >= their_sent[i] *
* *
* 'their_frame[] is updated by Process_Receive_Packet() *
* 'their_recv[] is updated by Process_Receive_Packet() *
* 'their_sent[] is updated by Process_Receive_Packet() *
* 'my_sent' is updated by this routine. *
* *
* The only routines allowed to pop up dialogs are: *
* Wait_For_Players() (only pops up the reconnect dialog) *
* Execute_DoList() (tells if out of sync, or packet recv'd too late) *
* *
* Sign-off's are detected by: *
* - Timing out while waiting for a packet *
* - Detecting that the other player is now at the score screen or *
* connection dialog (serial) *
* - If we see an EventClass::EXIT event on the private channel *
* *
* The current communications protocol, COMM_PROTOCOL_MULTI_E_COMP, has *
* the following properites: *
* - It compresses packets, so that the minimum number of bytes are *
* transmitted. Packets are compressed by extracting all info common to *
* the events into the packet header, and then sending only the bytes *
* relevant to each type of event. For instance, if 100 infantry guys *
* are told to move to the same location, the command itself & the *
* location will be included in the 1st movement command only; after *
* that, there will be a rep count then 99 infantry TARGET numbers, *
* identifying all the infantry told to move. *
* - The protocol also only sends packets out every 'n' frames. This cuts *
* the data rate dramatically. It means that 'MaxAhead' must be *
* divisible by 'n'; also, the minimum value for 'MaxAhead' is *
* 'n * 2', to give both sides some "breathing" room in case a FRAMEINFO *
* packet gets missed. *
* *
* Note: For synchronization-waiting loops (like waiting to hear from all *
* other players, waiting to advance to the next frame, etc), use *
* Net.Num_Connections() rather than NumPlayers; this reflects the *
* actual # of connections, and can be "faked" into playing even when *
* there aren't any other players actually there. A typical example of *
* this is playing back a recorded game. For command-execution loops, use *
* NumPlayers. This ensures all commands get executed, even if *
* there isn't a human generating those commands. *
* *
* The modem works a little differently from the network in this respect: *
* - The connection has to stay "alive" even if the other player exits to *
* the join dialog. This prevents each system from timing out & hanging *
* the modem up. Thus, packets are sent back & forth & just thrown away,*
* but each system knows the other is still there. Messages may be sent *
* between systems, though. *
* - Destroy_Null_Connection doesn't hang up the modem, so *
* Num_Connections() still reports a value of 1 even though the other *
* player has left. *
* - Any waits on Num_Connections() must also check for *
* NumPlayers > 1, to keep from waiting forever if the other *
* guy has left *
* - Packets sent to a player who's left require no ACK *
* *
* INPUT: *
* none. *
* *
* OUTPUT: *
* none. *
* *
* WARNINGS: *
* none. *
