Hello netlanders,
I am trying to port the xtank game written by Terry Donahue to an
Apollo running Domain-OS which supports BSD4.3 and Xwindows Version 11
release 2. All of it compiles just fine but there is some strange
code in there that handles the amount of time it gives all the
"Vehicles". It uses some "Mailbox Multitasker" package written by
Michael Benjamin Parker. This package plays some pretty weird games
with the jmp_buf that setjmp() and longjmp() use.
My question is this: Has anybody ever tried to port the xtank game to
the Apollo, and if so, were you successful, and if so, will you PLEASE
tell me what all you had to change to make it fly. If nobody has ever
gotten xtank to work, how about just the Mailbox Multitasker?
This is really a neat game (I was able to play it on a different type
of machine) and I would really like to be able to make it work on my
Apollo. If there is anybody out there who has time to try and make it
work I would be more than happy to send you the sources.
Type at you later,
Keith Cantrell

Subject: Need help with xtank (PLEASE HELP) Hello netlanders, I am trying to port the xtank game written by Terry Donahue to an Apollo running Domain-OS which supports BSD4.3 and Xwindows Version 11 release 2. All of it compiles just fine but there is some strange code in there that handles the amount of time it gives all the "Vehicles". It uses some "Mailbox Multitasker" package written by Michael Benjamin Parker. This package plays some pretty weird games with the jmp_buf that setjmp() and longjmp() use. One clue here is that the Apollo setjmp, longjmp() does not save all the registers that other setjmp,longjmp() calls do. You will either have to re-write setjmp,longjmp, or rewrite the code to use, say, CPS. My question is this: Has anybody ever tried to port the xtank game to the Apollo, and if so, were you successful, and if so, will you PLEASE tell me what all you had to change to make it fly. If nobody has ever gotten xtank to work, how about just the Mailbox Multitasker? xtank works as given, you just can't use anything that relies on threads - robot tanks, for example. If you play the 'players' game, which is just humans (and the very simple drones), then the game works fine for me. This is really a neat game (I was able to play it on a different type of machine) and I would really like to be able to make it work on my Apollo. I agree! If anyone gets working patches for robot ships and custom program driven ships, I'd really be interested in them! I started writing the stuff to do dynamic loading of the programs, but gave up for some reason (maybe lack of time).
