[ This is an X version of the classic game of robots. For those not familiar
with robots, the idea is that you are chased by robots and the object is to
make them crash into each other before they get you. This is a very nice
implementation of this game -- incredibly fun. --argv ]

README -- xrobots version 1.0 -- Thu May 25 13:23:49 PDT 1989
xrobots is a game that runs on X Windows. It is based on /usr/games/robots
and on The New Daleks (Macintosh). To create a runnable binary, type
make -f Makefile.nonImake
An Imakefile is also included.
Compile time parameters:
MAXX, MAXY -- these control the number of 'cells' in the playfield.
the default is 35x20. The realistic maximum these can be on a
1152x900 screen (ie most sun 3/50's) is about 50x40. With a larger
playfield, the scores will be higher and the game length longer, but
some graphics will appear slower. I'd be interested to see this
running on a bigger engine to see the effects. With a 35x20
playfield, scores in the 6000 range can be achieved.
MAXSCORES -- the number of high scores that you want to keep.
The default is 20.
The defaults for the binary is /usr/games/xrobots and the score
file is /usr/games/lib/xrobots_scores. The binary should have
write access to the high score file (xrobots will attempt to
create this itself).
There is a little bsd-ish stuff in score.c. flock is used to stop a race
condition. If you don't have a bsd-like flock, you could probably
comment it out. The race condition (multiple users writing to the
score file) is probably rare.
xrobots has been tested on Sun 3/50's 3/60's 3/280's running the X11R3
server. Also, it has been compiled and tested on a Pyramid running X11R2.
(You'll have to comment out the references to XtNresize in score.c if you
want it to compile under release 2.)
BUGS
The man page doesn't install by default. You'll have to do that yourself,
or if you are using imake, just remove the comments from the tail of the
Imakefile.
None known. There is a nasty bug in the awm window manager
that causes keypress events to be ignored. It shows up now and then...
rather than code around it, I prefer another window manager.

xrobots -- version 1.0\n\
\n\
Welcome to the world of xrobots. Where the bad guys (the robots) are \n\
incredibly stupid and the good guy (the smiley face) is outnumbered.\n\
You (as the good guy) can avoid death and achieve instant fame and \n\
gratification by appropriate use of the mouse and/or keyboard.\n\
\n\
The mouse: \n\
Clicking the left mouse button moves the smiley face one step in the \n\
direction of the pointer. Clicking directly on top of the smiley face \n\
takes a turn, but does not change it's position. \n\
\n\
Clicking the middle mouse button causes the smiley face to run like heck. \n\
Of course, the robots can run just as fast so it really doesn't matter... \n\
Or does it? \n\
\n\
Clicking the right mouse button gives the smiley a rest. This is the \n\
same as clicking on the 'wait' button.\n\
\n\
\n\
The keyboard: \n\
's' triggers the sonic screwdriver. \n\
't' triggers the teleportation device. \n\
'w' waits until robots are breathing down your neck. \n\
'.' waits one turn. \n\
\n\
Directional control:\n\
\n\
y k u \n\
\\|/ \n\
h- -l \n\
/|\\ \n\
b j n \n\
\n\
\n\
Well, that's the low down. If you don't like the mouse or keyboard set up,\n\
see the manual to find out about changing the translations. \n\

.TH XROBOTS 6 "11 May 1989"
.SH NAME
xrobots \- fight off villainous robots (X Windows)
.SH SYNOPSIS
.B /usr/games/xrobots
.SH DESCRIPTION
.LP
As in robots(6), xrobots puts you into a world of evil robots (but in
an X window, of course).
It's your intellect against the robots, who have numbers on their side.
Fortunately for you, these robots have a bad habit of crashing into
each other, destroying themselves and putting you in a better position
to survive.
.LP
You have a the following abilities:
.LP
.RS
You can move one square at a time (but so can the robots).
These directions are indicated by diamonds near your man.
Clicking the left mouse button selects the direction.
.LP
You can wait for robots to reach you. Do this by clicking on
the button labeled "Wait" below the main playfield or by
pressing 'w' while the mouse pointer is within the playfield.
.LP
You can use your teleportation device. This defensive weapon
is not without risk. This can be invoked by clicking on
"Teleport" or by pressing 't'.
.LP
You have a "sonic screwdriver" which wipes out any robots
within close proximity. This offensive weapon recharges once for
each level. This can be invoked by the "Sonic Screwdiver" button
or by pressing 's'.

.SH RESOURCES
.LP
If you don't like 's' for the sonic screwdriver and 't' for teleport
you can change this. xrobots is programmed using the X Toolkit and
takes advantage of the toolkit's resources and translation schemes.
For example, if you don't want all the spiffy graphics, place
the following line in your .Xdefaults file.
.LP
.RS
xrobots.spiffy: false
.RE
.LP
The default for this resource is true.
.LP
Additionally, all the key bindings can be changed. Here's a sample
set of translation bindings:
.LP
.RS
xrobots*Translations: #augment \\n\\
.RS
.nf
<Btn1Up>: move() \\n\\
<Key>u: move(right, up) \\n\\
<Key>l: move(right) \\n\\
<Key>n: move(right, down) \\n\\
<Key>y: move(left, up) \\n\\
<Key>h: move(left) \\n\\
<Key>b: move(left, down) \\n\\
<Key>k: move(up) \\n\\
<Key>j: move(down) \\n\\
<Key>.: move(nowhere) \\n\\
<Key>\\\\ : move(nowhere) \\n\\
<Btn2Up>: go_here() \\n\\
<Btn3Up>: wait() \\n\\
<Key>s: sonic() \\n\\
<Key>t: teleport() \\n\\
<Key>w: wait() \\n\\
<Key>z: new_game() \\n\\
:<Key>Q: quit()

Of course, these defaults should copied into your .Xdefaults file to
take effect. You studs out there might even use xrdb(1).

.SH ACTIONS
.LP
Here's what each action is and what it does:
.RS
.LP
The move() action with no parameters uses the relative position of the
mouse pointer to determine the direction in which to go. Otherwise,
a combination of "left", "right", "up", "down", and "nowhere" will
direct the direction. If "nowhere" is used, the player's icon will
remain still while the robots take their turn.
.LP
The go_here() action directs the player's icon to the location where the
mouse button was released. Of course, the robots will chase you, and
if doom is impending, go_here() will stop.
.LP
The wait() action causes the robots to move until they are breathing
right down your neck.
.LP
The sonic() action invokes the sonic screwdriver.
.LP
The teleport() action invokes the teleportation device.
.LP
The new_game() and quit() actions do what you would expect them to.
.LP
.SH SCORING
.LP
Each robot that is wasted is worth ten points. Additionally,
bonuses are awarded for each teleportation, and for not using the
sonic screwdriver. The name for the high score list comes from
the USER environment variable.
.LP
.SH FILES

.SH AUTHOR
.LP
There are many versions of robots floating around. So many that it
would be difficult to say who the original author is. This version was
written from scratch by Brian Warkentine.
