XBill history:
0.01 (7/21/94):
- Bill moves, and he's in color too. You can even click on
him and he excaims "OUCH!" or "SPLAT!"
- window resizing is very wrong
0.02 (7/22/94):
- program no longer guaranteed to run predictably for
longer than nine years (sorry)
- ridiculously improved code style (no really a lot!)
- added linked list unit and support for multiple monsters
- added support for computers
- bill says "POW!!!!!!" on button 2
- improved Makefile
- remembered to include app-defaults file in tar
0.03 (7/24/94):
- forgot to initialize a variable. either the stupid aix compiler
initialized it anyway or we were really lucky testing it.
- removed annoying flicker
- has multiple computers on the screen with random OSes
- has multiple bills moving on the screen in random directions
- used sxpm to create smaller .xpm files, minor savings in memoy
and executable size, easier to edit pixmaps
- left button (button 1) removes bills from screen
- right button (button 3) now resets computers to wingdows.
0.04 (7/25/94):
- got masking to work (well, maybe not...)
- bill now carries the wingdows box around
- event handling/speed improved
0.1 (7/26/94):
- masking really works now
- fixed computer pixmap so it looks nice(r)
- randomized computer layout now leaves room for bill to stand on right
- support for bills walking in, standing at computers and walking out
- bills walk towards a specific computer to plunder (primitive ai)
- bill turns off computer, 'steals' native os and installs wingdows
- count of bills remaining is kept: decreased when bill enters screen
- increased if bill leaves
- bill is killable in all states
- computer reset to native os on right button
- cleaned up code and internal structures
- event handling/speed really improved (optimized for the new code)
- server lag problems identified
- linked list unit fixed so that function to move between lists works
- window resizing is still very wrong
0.2 (8/14/94)
- programmers woke up after being asleep since 7/26.
- code structures were fixed very much (again)
- bill faces in the direction he's walking
- bill explodes in a gory shower of blood when clicked on (yeah!)
- bill drops os when killed
- the os stays on the ground when bill is killed if it had been stolen
- the os bounces up and down while bill carries it
- changed default cursor (matias will have to draw a better one later)
- cursor changes during drag and drop operation
- drag and drop works! there's a little hack involved, but not
too bad...
- bill now smart enough to notice that a computer is already
corrupted and find a new one
- game ends if all computers are lost
0.21 (8/15/94)
- attempt to port code to athena widgets. it compiles and
runs w/o motif now (i hate C macros) a bit
- improved the makefile. an imakefile one day maybe...
0.22 (8/16/94)
- when bill leaves the field, he drops the os he's carrying
- status bar widget now does something
0.3 (8/23/94)
- improved responsiveness a lot :)
- menubar does something (new game, pause and quit buttons) if
motif is used.
- levels now exist (barely)
- yet more code cleanup
0.31 (8/24/94)
- a few things depend on the level (freq. and number of appearing
bills, number of computers, step size)
- bug where a computer is ignored if off is removed
- menu code written.
- athena code started. this works more or less, but not too well.
i'd recommend using motif and/or a statically linked binary.
0.32 (9/18/94)
- about box works. help almost works also.
- a bunch of bugs fixed
- have an Imakefile now (thanks to Greg Seidman - anthro@cs.umd.edu)
0.9 (11/28/94 - a bit busier during school)
- warp to arbitrary level works
- game pauses when cursor leaves window
- cursor warps to near upper left corner of opened dialog boxes
- redefined both reset and drag to right button (button 3),
added -1 option for people with a one button mouse.
-1 may slow the game down a bit.
- added -l, -L to specify starting level
- added -v for version info
- improved pictures a lot
- added confirmations for actions
- game now pauses well
- fixed level difficulty stuff
- bill walks at two speeds
- minimizes to an icon (a cool one too...)
- scoring improved
- window cannot be resized now, no matter how hard you try :)
- much cooler animations for bill replacing os
- added high score list
- fixed lots of silly bugs
- made program not die from colormap error (i hope)
1.0 (4/5/95-4/9/95)
- remembered that the game's not done yet :)
- replaced usleep() calls with XtAppAddTimeout(). should make
the game more responsive
- changed all popup windows to modal dialogs. cleans up code
a lot
- removed Athena support, since it would take too long to finish.
- made a couple pixmaps a bit smaller
- changed colors to gray. why not?
- finally got everything to work with full colormaps
- got rid of app-defaults file. Not really used anyway
- Only uses one button now (any button). Easier to play.
- Some Imakefile fixes
1.1 (4/16/95)
- modularized widget code, and added Athena widget support (rewritten
from scratch). The game looks better with Motif, but that's
not too important.
- made pause button only active during game play
- warping to a level starts a game if one isn't being played
- fixed a potentially nasty bug that could cause bills to get lost
- works in TrueColor now (I think - it works in 16 bit mode at least)
1.1a (9/22/95)
- fixed bug where getopt() returned a char instead of an int.
- fixed bug where hitting Enter when entering a high score
corrupted the high score file.
- don't fclose() nonexistant files any more.
- added BSD as another operating system (patches by Joerg Wunsch,
joerg_wunsch@uriah.heep.sax.de)
- it was really easy to play forever by guarding one computer. Now
you lose when there's only one computer left running its
normal OS.
- added man page, written by Pekka Marjola (marjola@trshp.ntc.nokia.com)
2.0 (1/23/1997)
- changed around some timer code.
- removed Athena DrawingArea widget since CoreWidget works too.
- massive code reorganization to improve portability to other
GUIs, languages, etc.
- Some computers are connected by network cables
- When a computer with a network cable becomes infected, it will
release a spark down the cable which will infect the
computer on the other end. Pouring the bucket of water
on the spark will extinguish it.
- Made cursors and various other images look better.
- Removed references to defenestration.dorm.umd.edu, which no
longer exists.
- Added Red Hat logo (fixed broken Red Hat patch).
- Added GNU Hurd logo
- Added Linux penguin logo
- The BSD, Red Hat, Linux, OS/2, and Hurd operating systems are
interchangable on the 2 PC computers.
- The score is now displayed in the playing field.
- Made Athena version far better looking.
- Motif version almost completely works with Lesstif.
2.1 (11/15/2001)
- converted all code from C++ into C.
- cleaned up pretty much all of the code.
- modified build system to use GNU autoconf instead of imake.
- made the UI system modular, and created modules for the Athena
and Motif widget sets. By default, both are built into the
binary.
- added a GTK front end.
- added an option to use a larger playing field.
- changed the Athena front end to use Xaw3d when possible.
- add Palm OS/CPU (images borrowed from pBill and heavily modified)
