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.

game startup:
|
||||
<master and matcher>
|
||||
Master: send REGISTER to matcher with optional password, wait for ack. If
|
||||
timout, resend.
|
||||
matcher: Wait for REGISTER packet, when received maintain database. respond
|
||||
to sender with ACK. REGISTER packet can close a game also. The REGISTER
|
||||
packet sent by the master has a unique word to be used to avoid confusion.
|
||||
REGISTER packet also contains a game version #
|
||||
|
||||
After master registers game and receives ACK, just waits for slaves to contact.
|
||||
|
||||
<slave and matcher>
|
||||
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.
