Newsgroups: comp.sources.x Path: uunet!paladin.american.edu!darwin.sura.net!mips!msi!dcmartin From: Nathan Sidwell <nathan@inmos.co.uk> Subject: v18i022: Xmris - an X video game, Part01/09 Message-ID: <csx-18i022-xmris@uunet.UU.NET> Originator: dcmartin@fascet Sender: dcmartin@msi.com (David C. Martin - Moderator) Organization: Molecular Simulations, Inc. Date: Thu, 16 Jul 1992 17:08:22 GMT Approved: dcmartin@msi.com Lines: 1470 Submitted-by: Nathan Sidwell <nathan@inmos.co.uk> Posting-number: Volume 18, Issue 22 Archive-name: xmris/part01 From the README: Xmris is a version of the arcade game Mr Do, which will run under the X windowing system. You control a gnome, who can walk around a garden, along paths already marked, or create new paths wherever you wish. You also have a ball, which can be thrown in the direction you're facing, towards the gnome's feet. Points are scored for collecting cherries (if you collect 8 cherries without stopping, you get a bonus), killing monsters (by squashing them, or throwing the ball at them), and collecting the prize left when all the monsters have come out of their den. #!/bin/sh #

X You control a gnome, who can walk around a garden, along paths already marked, or create new paths wherever you wish. You also have a ball, which can be thrown in the direction you're facing, towards the gnome's feet. Points are scored for collecting cherries (if you collect 8 cherries without stopping, you get a bonus), killing monsters (by squashing them, or throwing the ball at them), and collecting the prize left when all the monsters have come out of their den. X Extra lives are obtained by filling in the 'EXTRA' monsters at the top of the screen. One of these comes out every 5000 points, and also when you get the prize, along with 3 drones. Killing the EXTRA will kill the drones too. When you collect the prize, the normal monsters freeze, until the three drones are dead. Beware things go faster after that! When all the normal monsters are killed or all the cherries collected, or you have got the final EXTRA monster, you advance to the next screen. X You can kill the monsters by throwing the ball at them, or dropping the apples on them. You get more points for squashing them. The EXTRA monsters and its drones, can eat the apples if they're walking towards it when they meet. You die by colliding with a monster (unless its eating an apple, in which case no harm done), or by being squashed be a falling apple. X GAME CONTROLS X The gnome can be controlled by the mouse or keyboard, this is selected when you start a new game. The gnome walks towards the mouse, and throws the ball when you press a button. You can move the mouse at right angles to the gnome's direction while its walking, the gnome continues towards the previous destination, before turning towards the new one. Mouse control is not that accurate for fine control of the gnome (I don't use it). Keyboard control is by 'z' and 'x' for left and right, and '\'' and '/' for up and down. The ball is thrown with the space bar. Pressing more than one key, will turn the gnome appropriately at the next intersection, so you can go round corners by pressing the new direction key before releasing the old one. If you try to go in a direction not possible, the gnome will move towards the nearest intersection or in the direction it was going, depending on how near to an intersection it was. X The game can be paused by iconifying it (when your boss walks in), or by pressing 'p'. When de-iconified, the game remains paused. To continue press space. When paused, you can abort the game by pressing 'q'. If the game is displaying the demo screens, 'q' will quit the game entirely. X OPTIONS X -help X Lists command arguments and version number X -display <display> X Display to run on X -font <font> X Text font name X -rv X Reverse video X -bw X Force black and white X -iconic X Starts iconified X -mris -msit X So not to be accused of gender bias, xmris can also be run as xmsit. The gender of the game is taken from the program name (mris or msit) and may be over ridden by two of the following switches. The game is known as Mr Is because the arcade game was masculine. (Happy now Geoff?) X The argument list is also fed to XSetStandardProperties, I don't know what this does. X PLAYING THE GAME X The game works best with all other processes asleep. If another process gets too much processor the animation will be jerky, and the load line along the bottom will start to grow. Because an interrupt is used to control the frame rate, the animation is smoother than with xchomp. X You probably want to position the pointer at the bottom of the window, so that it doesn't interfere with the board. You'll notice it flicker if one of the sprites moves under it. X BUGS X The game is always in black and white, I haven't got round to doing colour sprites yet, so the -bw argument is superfluous. X The -iconic argument has no effect. (I don't know how to get it to work.) X Fatal XIO errors are not handled gracefully. Quiting the game by using your window manager results in big error message. I don't know how to trap this. X The program was written with a folding editor, it might be hard to find your way around without one. X In order to get it to compile correctly with both K&R C and ANSI C, I've used several macros to deal with the differences in function prototyping and argument lists. These produce either proper K&R declarations or proper ANSI ones. I did have mixed declarations, with the correct promotions taken care of, but that doesn't work well for the one varargs function. It might make it hard for things like ctags to work. Maybe I'll revert to the mixed declarations. X Please report modifications and other bugs, so that they can be considered for inclusion in later releases (especially true of syste X specific stuff). X email to nathan@inmos.co.uk X Have fun.

You will have to do this to set the compiler, as, by default, Imakefile selects gcc with the standard includes not in /usr/include. Makefile.std doesn't do this, but uses the defaults. The source will compile with both ANSI and K&R compilers, provided that they both correctly define and undefine __STDC__. (But you all use ANSI now don't you.) Compilation should be straight forward. The only thing that might cause problems is the timer stuff in timer.c which set up a real-time interrupt to get the frame rate constant. If the frame rate is too high (ie the interrupt occurs before the game loop has completed) a load line along the bottom of the window will start to grow towards the left of the window. If this always grows, with all other processes dormant, you must slow the game down by increasing the frame rate. This can be done by fiddling with the FRAME variable in the Imakefile X To make on your system type X X xmkmf X make depend X make all X To install into your X bin use make install, but note that this only installs xmris, not xmsit. X Please report modifications, so that they can be considered for inclusion in later releases (especially true of system specific stuff). X email to nathan@inmos.co.uk X XXMRIS has been tested on the following systems X X Platform OS X release Colour X Sparcstation 1 Sunos 4.1 X11R4 B/W X NOTES TO PROGRAMMERS X XXMRIS uses pure Xlib, without toolkits, widgets, etc. This is mainly because I don't know anything about toolkits, widgets, etc. In fact, this program started out as an experiment in X Window System programming, hacking from Xchomp (by Jerry Shekhel), and using the header files (I don't even have an X manual!). There's not much of XXchomp code left, infact the only thing is the DEC_icon_atom stuff and some bits of create_resources. I improved the response by using a real time interrupt rather than delay for the timing and only updating the necessary parts of the display. X Have fun.

You also have a ball, which can be thrown in the direction you're facing, towards the gnome's feet. Points are scored for collecting cherries (if you collect 8 cherries without stopping, you get a bonus), killing monsters (by squashing them, or throwing the ball at them), and collecting the prize left when all the monsters have come out of their den. .PP Extra lives are obtained by filling in the 'EXTRA' monsters at the top of the screen. One of these comes out every 5000 points, and also when you get the prize, along with 3 drones. Killing the EXTRA will kill the drones too. When you collect the prize, the normal monsters freeze, until the three drones are dead. Beware things go faster after that! When all the normal monsters are killed or all the cherries collected, or you have got the final EXTRA monster, you advance to the next screen. .PP You can kill the monsters by throwing the ball at them, or dropping the apples on them. You get more points for squashing them. The EXTRA monsters and its drones, can eat the apples if they're walking towards it when they meet. You die by colliding with a monster (unless its eating an apple, in which case no harm done), or by being squashed be a falling apple. .PP The game works best with all other processes asleep. If another process gets too much processor the animation will be jerky, and the load line along the bottom will start to grow. Because an interrupt is used to control the frame rate, the animation is smoother than with xchomp. .PP You probably want to position the pointer at the bottom of the window, so that it doesn't interfere with the board. You'll notice it flicker if one of the sprites moves under it. .SH GAME CONTROLS .PP The gnome can be controlled by the mouse or keyboard, this is selected when you start a new game. The gnome walks towards the mouse, and throws the ball when you press a button. You can move the mouse at right angles to the gnome's direction while its walking, the gnome continues towards the previous destination, before turning towards the new one. Mouse control is not that accurate for fine control of the gnome (I don't use it). Keyboard control is by 'z' and 'x' for left and right, and '\'' and '/' for up and down. The ball is thrown with the space bar. Pressing more than one key, will turn the gnome appropriately at the next intersection, so you can go round corners by pressing the new direction key before releasing the old one. If you try to go in a direction not possible, the gnome will move towards the nearest intersection or in the direction it was going, depending on how near to an intersection it was. .PP The game can be paused by iconifying it (when your boss walks in), or by pressing 'p'. When de-iconified, the game remains paused. To continue press space. When paused, you can abort the game by pressing 'q'. If the game is displaying the demo screens, 'q' will quit the game entirely. .SH OPTIONS .TP 4 .B \-help Lists the command options and some other info, and does not start the game. .TP 4 .B \-display \fIdisplay\fP Specifies which X server to connect to. .TP 4 .B \-font \fIfont\fP Specifies which font to use. .TP 4 .B \-rv Swap black and white colours. .TP 4 .B \-bw Use black and white, even on colour displays. .TP 4 .B \-iconic Start up iconized. .TP 4 .B \-mris .TP 4 .B \-msit So not to be accused of gender bias, xmris can also be run as xmsit. The gender of the game is taken from the program name (mris or msit) but may be over ridden by these two switches. The game is known as Mr Is because the arcade game was masculine. .PP The argument list is also fed to XSetStandardProperties, I don't know what this does. .SH SEE ALSO xchomp(6) .SH BUGS .PP The game is always in black and white, I haven't got round to doing colour sprites yet, so the -bw argument is superfluous. .PP The -iconic argument has no effect. (I don't know how to get it to work.) .PP Fatal XIO errors are not handled gracefully. Quiting the game by using your window manager results in big error message. I don't know how to trap this. .PP The program was written with a folding editor, it might be hard to find your way around without one. .PP In order to get it to compile correctly with both K&R C and ANSI C, I've used several macros to deal with the differences in function prototyping and argument lists. These produce either proper K&R declarations or proper ANSI ones. I did have mixed declarations, with the correct promotions taken care of, but that doesn't work well for the one varargs function. It might make it hard for things like ctags to work. Maybe I'll revert to the mixed declarations or maybe I won't support K&R. .SH COMMENTS .PP I welcome any comments, suggestions, code, bug reports and fixes, etc. Don't forget to include which version of .I xmris you are using (with xmris -help), machine, OS, X release & patch number, window manager etc. .SH COPYRIGHT Copyright (C) 1992 Nathan Sidwell. .SH AUTHOR Nathan Sidwell (nathan@inmos.co.uk) SHAR_EOF chmod 0644 xmris.man || echo 'restore of xmris.man failed' Wc_c="`wc -c < 'xmris.man'`" test 5444 -eq "$Wc_c" || echo 'xmris.man: original size 5444, current size' "$Wc_c" rm -f _shar_wnt_.tmp fi # ============= patchlevel.h ============== if test -f 'patchlevel.h' -a X"$1" != X"-c"; then echo 'x - skipping patchlevel.h (File already exists)' rm -f _shar_wnt_.tmp else > _shar_wnt_.tmp echo 'x - extracting patchlevel.h (Text)' sed 's/^X//' << 'SHAR_EOF' > 'patchlevel.h' && #define XMRISVERSION "V1.01" SHAR_EOF chmod 0644 patchlevel.h || echo 'restore of patchlevel.h failed' Wc_c="`wc -c < 'patchlevel.h'`" test 29 -eq "$Wc_c" || echo 'patchlevel.h: original size 29, current size' "$Wc_c" rm -f _shar_wnt_.tmp fi # ============= xmris.h ============== if test -f 'xmris.h' -a X"$1" != X"-c"; then echo 'x - skipping xmris.h (File already exists)' rm -f _shar_wnt_.tmp else > _shar_wnt_.tmp echo 'x - extracting xmris.h (Text)' sed 's/^X//' << 'SHAR_EOF' > 'xmris.h' && /*{{{ (C) 1992 Nathan Sidwell*/ /***************************************************************************** X X M R I S V1.01 X --------------- X (C) 1992 Nathan Sidwell X This program is copyright (C) 1992 Nathan Sidwell.
