.TH WARP 6
.SH NAME
warp - a real-time space war game
.SH SYNOPSIS
.B warp [options]
.SH DESCRIPTION
.I Warp
is a real-time space war game that requires skill and quick thinking.
"Real-time" in this context means that the enemies keep moving (and shooting)
even if you don't.
A unique feature of
.I warp
is that blast propagates; it is unhealthy to remain near things that are
in the process of blowing up.
If a given universe is above a critical density it may chain react.
Scoring is like many popular arcade games--there are multiple waves which
get harder and harder as you go along.
Nobody has ever maxed out the scoreboard without cheating.
.PP
Unlike many space-war games,
.I warp
is not simply a shooting gallery.
Along with phasers and photon torpedoes, you have tractor beams and a cloaking
device.
Skill in navigation is important.
It helps to be schizophrenic, because you must manage an Enterprise and a Base
simultaneously.
And enemies do not simply shoot back.
You can get tailed, absorbed, snuck up upon, hemmed in, rammed, loved to death,
reprimanded for destroying civilized life, dragged around, robbed, damaged
and eaten.
And if you should happen to get bored by the enemies (a trifle unlikely),
you can always watch the interesting star patterns.
In fact, you'll have to, since your tactics will depend upon what kind of
universe you find yourself in.
.PP
.I Warp
is played in a double wraparound universe, i.e. the bottom is connected to the
top, and the right is connected to the left.
You need a crt with random cursor addressing and at least 24 lines by 80
columns.
For more information about about how to play, simply run
.I warp
and say "y" when it asks if you want to see the instructions.
There is also a single-page command summary that you can get while playing
by typing a "?".
.PP
Command line options include:
.TP 5
.B -b
Put
.I warp
into beginner mode.
Makes the difficulty increase more slowly, but penalizes you for it.
.TP 5
.B -d<n>
Sets the initial difficulty to
.BR n .
.TP 5
.B -l
Play a low-speed game.
Changes the basic cycle time from 1 second to 2 seconds.
This switch is automatically set at baud rates below 2400.
You may want to set it at higher speeds if your terminal cannot keep up
with the output.
(This should never happen on BSD systems, which have an IOCTL call to
determine output queue length.)
Because this makes the game easier, a separate scoreboard is kept for
low-speed games.
.TP 5
.B -m
Terminal has a meta key which turns on the eighth bit.  Ordinarily the
eighth bit is stripped in order to ignore parity.
Metacharacters will appear to the keymap as prefixed with a ^A, and will
subsequently have the same effect as a control character, unless otherwise
mapped.
.TP 5
.B -s
Just prints out the scoreboards and saved games and then exits.
.TP 5
.B -v
Prints out the version number.
.TP 5
.B -x
Play an experimental game.
This causes
.I warp
to ignore any saved game, and disables the ability to save
the current game.
Thus you can play around with something or show
.I warp
to someone without jeopardizing a currently saved game.
.SH ENVIRONMENT
.TP 5
.B WARPMACRO
If defined, names a file containing keyboard mappings and macros.
If not defined, the value %X/Kbmap.%{TERM} is assumed.
The macro file contains lines of the following form:
.sp
<keystroke-sequence> <whitespace> <canonical-keystroke-sequence>
.sp
You may use certain % interpolations and ^<letter> control characters.
For possible % interpolations see warp.h.
Sequences in the canonical-keystroke-sequence bounded by ^(...^) are
subject to reinterpretation via the keymap.
This file has two major uses.
First, you can set up your commands to use any kind of prefix key your terminal
might have, or change the key bindings in any other way you choose.
Second, you can define arbitrary macros, such as this:
.sp
# define Corbamite maneuver
=	DDllllll

.SH DIAGNOSTICS
Generally self-documenting, as they say.
.SH BUGS
Addicting.
At the end of a wave, all you have to do to keep going is hit a space.
You see the message "Hit space to continue" and automatically hit space.
About 2 seconds later you remember you wanted to go home, but by then
it's too late to escape without penalty.
.PP
You can't kill a backgrounded
.I warp
process directly, because it is running setuid.
You have to use the killer built in to
.IR warp .
.PP
Now that there is a space amoeba, there ought to be tribbles.
But it might be too much trouble...
