Turned on -Wall in Makefile, got rid of all the warnings. Made Makefile.osx |
||||
for building on OSX. Added some syntax checking for passing the "-m <host>" |
||||
command line parameter. Got rid of all the damage lists (rectangles on the |
||||
window that need to be updated) and instead just do a full screen update |
||||
whenever necessary. |

||||
Changed secondary control from ALT keys to 'b' key. On win32 the alt has |
||||
special meaning and can cause events to be dropped, so a key up event is |
||||
lost and the player gets stuck moving in some direction. |
||||

||||
Finished sdl port, the sockets problem stemmed from windoze not implementing |
||||
Berkeley Sockets in a compatible manner. The program must call |
||||
WSAStartup and WSACleanup on begin and end. Also instead of close on a |
||||
socket you've got to call closesocket. This requires ugly |
||||
#if defined(__WIN32__) |
||||
... |
||||
#endif |
||||
sections in the code, which defeats the purpose of a nice platform |
||||
indpendent source tree. Blame it on M$. |
||||

||||
Began converting X code to SDL code for portability. Having trouble with |
||||
sockets library under win32. Converted all the graphics rendering routines to |
||||
SDL, also dealt with the events translation. Under win32 the alt key can |
||||
cause stuck keys. Still no pause() equivalent, ie wait until the timer |
||||
interrupt occurs, but stay off the bus without eating cpu cycles. |
||||
|
||||
No sound conversion yet. |
||||

||||
Finally got around to dealing with old email... As per Christoph Frick's |
||||
<ridcully@futurebyte.net> suggestion I added his idea of a |
||||
"-m <matcher>" command line argument to |
||||
specify at run time the matcher to use. |
||||
Thanks Christoph! |
||||
|
||||
I've bumped the version to 101. |

This is work in progress and might be of absolutely no use whatsoever. |
||||
|
||||
This is a Bomberman clone. I bought a game called Atomic Bomberman and found |
||||
it awful, there were intolerable delays after each game in network play while |
||||
the game was downloading data (what data?) over the network. Really crappy job |
||||
they did but I liked the artwork and sound effects. |
||||
|
||||
Atomic Bomberman was a DOS/win95 game. I looked under linux games and found |
||||
xblast but it was unusable for various reasons. For example its network |
||||
support just relies on xwindows networking--before entering the game you've |
||||
got to type in the host:display of each person who will be playing. Only |
||||
the main machine gets any sound. Also in the game you kept moving in whatever |
||||
direction you had last hit until you hit a wall or hit another direction. |
||||
There was no point in using the source as a starting point, there were so |
||||
many critical design flaws in that version I decided to write my own game from |
||||
scratch. |
||||
|
||||
Currently the game will most likely only be playable on a LAN. |
||||
|
||||
Some machine must run the matcher program. Players register their game with |
||||
the matcher machine, and joiners query the matcher machine to get a list of |
||||
active games. On xdr.com there is a matcher program running and the bomber.c |
||||
mname[] definition points to xdr.com. I tried it and it didn't work on my |
||||
own LAN through a firewall. You can try the game as is and it might work using |
||||
xdr.com as a matcher. Otherwise you'll have to run your own matcher daemon on |
||||
some machine. Assuming you have 3 machines tom, dick and harry and you want |
||||
to play a 3 player game, you would modify bomber.c's mname definiton to |
||||
be (line 47 of bomber.c) |
||||
char mname[]="tom"; |
||||
Then on tom run the matcher program as a background task. |
||||
Compile and distribute duplicate copies of bomber and data/* files, then |
||||
run bomber on each machine. The menus should be self explanatory--one person |
||||
selects HOST NETWORK GAME and the other people select JOIN NETWORK GAME. |
||||
|
||||
----------------- How to play --------------------------- |
||||
You've got to blow up other players to win. Spacebar drops a bomb. Get away |
||||
and hope your enemy gets hit by the flame. The 'b' key is a 2nd control |
||||
for when you are lucky enough to pick up the bomb control--looks like a |
||||
bomb with a timer on it. When you have that the bomb won't go off until |
||||
detonated by another bomb, you are killed, or you press 'b'. |
||||
|
||||
Blowing up bricks might result in prizes, most of which are good. |
||||
Skates = speed up |
||||
Bomb = allow you to have one more active bomb |
||||
flame = Increase bomb strength |
||||
turtle = makes you move very slowly |
||||
bomb with timer = controlled bomb detonation with 'b' key. |
||||
gold flame = Set flame strength to max |
||||
|
||||
There isn't much point in playing the game alone (single player). In that |
||||
case the only thing to avoid is accidentally killing yourself. Big deal... |
||||
It's really a multiplayer game. |
||||
|
||||
----------------- Left to do: ------------------- |
||||
Come up with a better scheme for internet play, as it is any latency will |
||||
kill the game playability. Works fine on LAN though. |
||||
|
||||
Figure out why matching doesn't work through a firewall... |
||||
[Specific case is 2 machines on my LAN cannot be matched by a machine that |
||||
is outside the firewall, and the firewall machine is doing IP masquerading. |
||||
Net result is matcher gets remapped IP addresses and these mean nothing |
||||
inside the LAN, only make sense when used from the outside world] |
||||
|
||||
Score. |
||||
|
||||
Remap movement keys not implemented. |
||||
|
||||
Allow game hoster to set network game options and have them visible to players |
||||
who have joined the game. |
||||
|
||||
Alternate gfx sets. |
||||
|
||||
Better handling of 8 bit mode with limited palette. |
||||
|
||||
Computer controlled things that can kill you. |
||||
|
||||
Other bonus types that can be harmful, such as skull. |
||||
|
||||
Internet play where everything is asynchronous, thus playable with a fixed |
||||
latency. As it is now slaves send to master, then master sends back to |
||||
slaves, and this data xfer must complete before the game can advance a step. |
||||
For internet this would be intolerable. I've never tried though... |
||||
|
||||
Better docs, online explanations, attract mode... |
||||
|
||||
Single player with computer controlled figures that must be killed/avoided. |

matcher: Wait for REGISTER packet, when received maintain database. respond |

packet sent by the master has a unique word to be used to avoid confusion. |

REGISTER packet also contains a game version # |

slave: send QUERY to matcher with optional password, wait for INFO, if timeout, |

resend. |
||||
matcher: respond to QUERY with INFO packet. matcher need not maintain any |
||||
database for slave requests. INFO packet contains IP addr and port for each |
||||
master machine that matches the QUERY spec (ALL or password). Only a |
||||
certain MAX # of entries are sent if there are too many to choose from. |

|

<slave and master> |
||||
slave: send JOIN to master, wait for INVITE. If timeout, resend. JOIN packet |
||||
contains the unique word the master created. JOIN also contains username. |
||||
master: Respond to JOIN with INVITE. INVITE contains unique word from JOIN |
||||
packet. INVITE either contains NO meaning game no longer exists or is closed |
||||
or player is not invited. IF yes, INVITE contains info on other players |
||||
already in the game (username and slot # for each). Master allocates the |
||||
slots and avoids confusion based on IP addr and port #. INVITE also contains |
||||
game options structure. Whenever a new player JOINS and is admitted, master |
||||
sends updated INVITE packets to everyone already in the JOIN list. Whenever |
||||
master changes game options, master sends out another set of INVITES |

||||
Duplicate JOINS are answered with updated INVITE but nothing changes as far |
||||
as allocation. |

|

Master player launches game after he's satisfied everyone has joined. |

Master sends BEGIN packet to everyone. BEGIN is identical to INVITE except |
||||
that the data is final. Slave must respond with its first MYDATA packet with |
||||
frame # of 0. If master times out waiting, master sends duplicate BEGIN to |
||||
wayward slaves. Once master has received MYDATA from everyone, game starts. |
||||
|
||||
Within game slave sends MYDATA to master and waits for STEP packet. If |
||||
timeout, slave sends duplicate MYDATA. |
||||
|
||||
If master times out waiting for a slave's MYDATA, slave gets dropped. MYDATAs |
||||
received will be answered with PKT_QUIT. |
