.Os
.Sh NAME
.Nm hunt
.Nd a multi-player multi-terminal game
.Sh SYNOPSIS
.Nm
.Op Fl bcfmqSs
.Op Fl n Ar name
.Op Fl p Ar port
.Op Fl t Ar team
.Op Fl w Ar message
.Oo
.Op Fl h
.Ar host
.Oc
.Sh DESCRIPTION
The object of the game
.Nm
is to kill off the other players.
There are no rooms, no treasures, and no monsters.
Instead, you wander around a maze, find grenades, trip mines, and shoot down
walls and players.
The more players you kill before you die, the better your score is.
If the
.Fl m
flag is given,
you enter the game as a monitor
.Po
you can see the action but you cannot play
.Pc .
.Pp
.Nm
looks for an active game on the local network.
The location of the game may be specified by giving the
.Ar host
argument.
This presupposes that a hunt game is already running on that host:  see
.Xr huntd 6
for details on how to set up a game on a specific host.
If more than one game is found, you may pick which game to play in.
If no games are found,
.Nm
will exit.
.Pp
If the
.Fl q
flag is given,
.Nm
queries the local network
.Pq or specific host
and reports on all active games found.
This is useful for shell startup scripts, e.g., csh's
.Pa .login .
.Pp
The player name may be specified on the command line by using the
.Fl n
option.
.Pp
The
.Fl c ,
.Fl s ,
and
.Fl f
options are for entering the game cloaked, scanning, or flying, respectively.
.Pp
The
.Fl b
option turns off beeping when you reach the typeahead limit.
.Pp
The
.Fl t
option aids team play by making everyone else on your team
appear as the team name.
A team name is a single digit to avoid conflicting with other characters
used in the game.
Use a team name consisting of a single space
.Pq Sq \
to remain on your own.
.Pp
The
.Fl p
.Ar port
option allows the rendezvous port number to be set.
.Pp
The
.Fl w
.Ar message
option is the only way to send a message to everyone else's screen when
you start up.
It is most often used to say
.Dq eat slime death - NickD's coming in .
.Pp
When you die and are asked if you wish to re-enter the game,
there are other answers than just yes or no.
You can also reply with a
.Ic w
to write a message before continuing or
.Ic o
to change how you enter the game
.Pq cloaked, scanning, or flying .
.Sh "PLAYING HINTS"
.Nm
only works on terminals with at least 24 lines, 80 columns, and
cursor addressing.
The screen is divided in to 3 areas.
On the right hand side is the status area.
It shows damage sustained,
charges remaining,
who's in the game,
who's scanning
.Po
the
.Ql \&*
in front of the name
.Pc ,
who's cloaked
.Po
the
.Ql \&+
in front of the name
.Pc ,
and other players' scores.
The rest of the screen is taken up by your map of the maze.
The 24th line
is used for longer messages that don't fit in the status area.
.Pp
.Nm
uses the same keys to move as
.Xr vi 1
does, i.e.,
.Ic h ,
.Ic j ,
.Ic k ,
and
.Ic l
for left, down, up, right, respectively.
To change which direction you're facing in the maze,
use the upper case version of the movement key
.Po
i.e.,
.Ic HJKL
.Pc .
You can only fire or throw things in the direction you're facing.
.Pp
Other commands are:
.Bl -tag -width Ic -compact
.It Ic f No or Ic 1
Fire a bullet
.Pq Takes 1 charge
.It Ic g No or Ic 2
Throw grenade
.Pq Takes 9 charges

.It Li \&/|\e
.El
.Pp
Other helpful hints:
.Bl -bullet -compact
.It
You can only fire in the direction you are facing.
.It
You can only fire three shots in a row before the gun must cool off.
.It
Shots move 5 times faster than you do.
.It
To stab someone,
you face that player and move at them.
.It
Stabbing does 2 points worth of damage and shooting does 5 points.
.It
Slime does 5 points of damage each time it hits.
.It
You start with 15 charges and get 5 more every time a player enters
or re-enters.
.It
Grenade explosions cover a 3 by 3 area, each larger bomb cover a
correspondingly larger area
.Po
ranging from 5 by 5 to 21 by 21
.Pc .
All explosions are centered around the square the shot hits and
do the most damage in the center.
.It
Slime affects all squares it oozes over.
The number of squares is equal to the number of charges used,
multiplied by
.Va slimefactor
as set by
.Xr huntd 6
.Pq default 3 .
.It
One small mine and one large mine are placed in the maze for every new player.
A mine has a 2% probability of tripping when you walk forward on to it;
50% when going sideways;
95% when backing up.
Tripping a mine costs you 5 points or 10 points, respectively.
Defusing a mine is worth 1 charge or 9 charges, respectively.
.It
You cannot see behind you.
.It
Cloaking consumes 1 ammo charge per 20 of your moves.
.It
Scanning consumes 1 ammo charge per (20 \(mu the number of players)
of other player moves.
.It
Turning on cloaking turns off scanning \(em turning on scanning turns off
cloaking.
.It
When you kill someone,
you get 2 more damage capacity points and 2 damage points get taken away.
.It
Maximum typeahead is 5 characters.
.It
A shot destroys normal
.Pq i.e., non-diagonal, non-door
walls.
.It
Diagonal walls deflect shots and change orientation.
.It
Doors disperse shots in random directions
.Pq up, down, left, right .
.It
Diagonal walls and doors cannot be destroyed by direct shots but may
be destroyed by an adjacent grenade explosion.
.It
Slime goes around walls, not through them.
.It
Walls regenerate, reappearing in the order they were destroyed.
One percent of the regenerated walls will be diagonal walls or doors.
When a wall is generated directly beneath a player, he is thrown in
a random direction for a random period of time.
When he lands, he
sustains damage
.Po
up to 20 percent of the amount of damage already sustained
.Pc ;
i.e.,
the less damage he had, the more nimble he is and
therefore less likely to hurt himself on landing.
.\"It
.\"There is a volcano close to the center of the maze which goes off
.\"close to every 30 deaths.
.It
Every 30 deaths or so, a
.Ql \&?
will appear.
It is a wandering bomb which will explode when it hits someone, or
when it is slimed.
.It
If no one moves, everything stands still.
But see the
.Va simstep
configuration variable in
.Xr huntd 6
.It
The environment variable
.Ev HUNT
is checked to get the player name.
If you don't have this variable set,
.Nm
will ask you what name you want to play under.
If you wish to set other options than just your name,
you can enumerate the options as follows:
.Dl setenv HUNT "name=Sneaky,team=1,cloak,mapkey=zoFfGg1f2g3F4G"
sets the player name to Sneaky,
sets the team to one,
sets the enter game attribute to cloaked,
and the maps
.Ic z No to Ic o ,
.Ic F No to Ic f ,
.Ic G No to Ic g ,
.Ic 1 No to Ic f ,
.Ic 2 No to Ic g ,
.Ic 3 No to Ic F ,
and
.Ic 4 No to Ic G .
The
.Ic mapkey
option must be last.
Other options are:
.Ic scan , fly , nobeep ,
.Ic port= Ns Ar string ,
.Ic host= Ns Ar string ,
and
.Ic message= Ns Ar string
\(em which correspond to the command line options.
String options cannot contain commas since commas
are used to separate options.
.It
It's a boring game if you're the only one playing.
.El
.Pp
Your score is the decayed average of the ratio of number of kills to number
of times you entered the game and is only kept for the duration
of a single session of
.Nm .
.\" .Pp
.\" .Nm
.\" normally drives up the load average to be approximately
.\" (number_of_players + 0.5) greater than it would be without a
.\" .Nm
.\" game executing.
.Sh STATISTICS
The
.Fl S
option fetches the current game statistics.
.Pp
Two groups of statistics are presented: the first group of statistics is
that of the clients currently connected to the game, and is reset each
time the client rejoins, while the second group of statistics is on all
players
.Pq dead or alive
by name, and collected over the lifetime of the
game daemon.
.Pp

.Bl -tag -width No -compact -offset
.It Score
the player's last score
.It Ducked
how many shots a player ducked
.It Absorb
how many shots a player absorbed
.It Faced
how many shots were fired at player's face
.It Shot

.Sq p

endless hours of play-testing to improve the character of the game.
