This is Mazewar for UNIX. It is a direct descendant of the Mazewar played at MIT and Xerox PARC, and boasts none of the embellishments found in other such programs. It's basically just run, peek, and shoot; no robot amenuenses, teleport traps, or other such fluff.

Basically, ASDF and space move you around, middle mouse shoots, left and right mouse let you peek around corners. Type Q to quit. Lefties may use the numeric pad instead of ASDF; on a DEC LK201 keyboard, the 456, row serves for ASDF, and the right cursor arrow is equivalent to the space bar. Q quits.

Games are normally begun by broadcasting to find members of a game; if your system doesn't allow normal users to do broadcasts, you'll have to do something like run it setuid root (or whomever) and change findDuke$init.c to do a setuid(getuid()) after the broadcast. The code as distributed does a broadcast to INADDR_BROADCAST (all 1s); your network might still be configured to use INADDR_ANY (all 0s). The place to change this is in the declaration of CFLAGS in the Makefile.

Also, the 4.3 setsockopt() call is pickier about its arguments when trying to enable broadcasting. Define BSD_43 in the Makefile to compile the appropriate code for 4.3 and 4.3-derived systems. The code that worked on 4.2 is still available for systems that might not like the new arguments.

If you know you don't have broadcast ability and never will, define NO_BROADCAST in the Makefile, and that code will be compiled out of init.c; mazefind isn't touched, but it won't do anything useful. In this case, you must specify a duke host (the name of any host currently in a game will do) or the players won't be able to find each other.

In each game there is one player who is designated the "duke" and manages the joining and leaving of other players. When starting a game, if you wish to join a specific game, especially one on a different net, you may specify the name of the duke host, which will be contacted directly. This has not been extensively tested. Games across long network delays might be pretty strange...

Bob Brown, Malcolm Slaney, and Mike Yang deserve a long round of applause for having ported to new window systems. We've tested it on a lot of architectures, but byte- or bit-order bugs may still be lurking. Note that there is conditional code in the X11 driver to not use server-resident bitmaps if your server doesn't do them right (this was designed for the QDSS).

Have fun, chris
