SpaceWar
--------
SpaceWar has two executables: the server and the game.
The server:
The server code should run on any UNIX system. It registers players,
passes important messages between them, and handles contention for non-
sharable resources (namely flags). Start the server on any system, then
use the server's hostname when starting the game.
The game:
The game code uses Inventor, Motif, and GL and therefore only runs
on systems with graphics heads (it requires a Z buffer too).
Playing:
To play first start the server on some system (type 'sws'). The server
will take up very little CPU time even when a game is going on because it
only wakes up when there is an important message to handle. It ignores
the ship information broadcast packets flooding the network.
Once the server is running, players may join. You must supply a server
to connect to, a team to play on, and a call sign to use. The usage is:
sw -n callsign -s server teamname
The first character of teamname is significant and may be one of 'r', 'g',
'b', or 'p' for the red, green, blue, or purple team, respectively.
See the help pages (sw.hlp in showcase format) for detailed information
on how to play.
Implementation notes:
* I needed to fix /usr/include/gl/image.h to work with C++.
The only change was to add parameters to the iopen call.
Original: IMAGE *iopen();
Fixed: IMAGE *iopen(char*, char*);
IMPORTANT!!! This change must be made for the program to compile.
* The explosion movie was shamelessly sampled from "Star Wars"
so there may be some copyright problems.
* The audio was taken from the Prosonus sounds and the bz sounds
supplied with IRIS systems.
* You may notice some references to a radio. This was not
implemented.
* The explosion display sometimes causes a graphics FIFO timeout.
This is not consistently reproducible (it's pretty rare).
The following are taken from SYSLOG:
WARNING: Gr2PixelDma: TIMEOUT gfx DMA did not complete
(finish flag not set)
WARNING: Gr2PcxSwap: TIMEOUT gfx context switch did not
complete (Start)
WARNING: Graphics error: GE PC = 0x4056
* Much of the game can be customized with resources. The following
resources are defined (listed with the app-defaults):
sw*label*fontList: -*-helvetica-bold-r-normal-*-14-*
sw*info*fontList: -*-helvetica-medium-r-normal-*-14-*
sw*XmText.background: #999999

sw*regularName: Regular
sw*explosionDirectory: .
sw*soundsDirectory: .
sw*geometry: 1000x740
The geometry resource given is suitable for small displays. For a larger
display 1280x880 works better.
