.SH NAME
|
|
atc \- air traffic controller game
|
|
.SH SYNOPSIS
|
|
.B atc
|
|
-[u?lstp] [-[gf] game_name] [-r random seed]
|
|
.SH DESCRIPTION
|
|
.LP
|
|
.I Atc
|
|
lets you try your hand at the nerve wracking duties of the air traffic
|
|
controller without endangering the lives of millions of
|
|
travelers each year.
|
|
Your responsibilities require you to direct the flight of jets
|
|
and prop planes into and out of the flight arena and airports.
|
|
The speed (update time) and frequency of the planes depend on the
|
|
difficulty of the chosen arena.
|
|
.SH OPTIONS
|
|
.LP
|
|
.TP 8
|
|
.B \-u
|
|

|
|
.B \-u.
|
|
.TP
|
|
.B \-l

|
|
installation of the program.
|
|
.TP
|
|
.B "\-g game"
|
|
Play the named game. If the game listed is not one of the
|
|
ones printed from the
|
|
.B \-l
|
|
option, the default game is played.
|
|
.TP
|
|

|
|
.B \-g.
|
|
.TP
|
|
.B "\-r seed"
|
|
Set the random seed. The purpose of this flag is questionable.
|
|
.SH GOALS
|
|
.LP
|
|
Your goal in
|
|
.I atc
|
|
is to keep the game going as long as possible.
|
|
There is no winning state, except to beat the times of other players.
|
|
You will need to: launch planes at airports (by instructing them to
|
|
increase their altitude); land planes at airports (by instructing them to
|
|
go to altitude zero when exactly over the airport); and maneuver planes
|
|
out of exit points.
|
|
.LP
|
|
Several things will cause the end of the game.
|
|
Each plane has a destination (see information area), and
|
|
sending a plane to the wrong destination is an error.
|
|
Planes can run out of fuel, or can collide. Collision is defined as
|
|
adjacency in any of the three dimensions. A plane leaving the arena
|
|
in any other way than through its destination exit is an error as well.
|
|
.LP
|
|
Scores are sorted in order of the number of planes safe. The other
|
|
statistics are provided merely for fun. There is no penalty for
|
|
taking longer than another player (except in the case of ties).
|
|
.LP
|
|
Suspending a game is not permitted. If you get a talk message, tough.
|
|
When was the last time an Air Traffic Controller got called away to
|
|
the phone?
|
|
.SH "THE DISPLAY"
|
|
.LP
|
|
Depending on the terminal you run
|
|
.I atc
|
|
on, the screen will be divided into 4 areas.
|
|
It should be stressed that the terminal driver portion of the
|
|
game was designed to be reconfigurable, so the display format can vary
|
|
depending the version you are playing. The descriptions here are based
|
|
on the ascii version
|
|
of the game. The game rules and input format, however,
|
|
should remain consistent.
|
|
Control-L redraws the screen, should it become muddled.
|
|
.SS RADAR
|
|
.IP
|
|
The first screen area is the radar display, showing the relative locations
|
|
of the planes, airports, standard entry/exit points, radar
|
|
beacons, and "lines" which simply serve to aid you in guiding
|
|
the planes.
|
|
.IP
|
|
Planes are shown as a single letter with an altitude. If
|
|
the numerical altitude is a single digit, then it represents
|
|
thousands of feet.
|
|
Some distinction is made between the prop
|
|
planes and the jets. On ascii terminals, prop planes are
|
|
represented by a upper case letter, jets by a lower case letter.
|
|
.IP
|
|
Airports are shown as a number and some indication of the direction
|
|
planes must be going to land at the airport.
|
|
On ascii terminals, this is one of '^', '>', '<', and 'v', to indicate
|
|
north (0 degrees), east (90), west (270) and south (180), respectively.
|
|
The planes will also
|
|
take off in this direction.
|
|
.IP
|
|
Beacons are represented as circles or asterisks and a number.
|
|
Their purpose is to offer a place of easy reference to the plane pilots.
|
|
See 'the delay command' under the input section of this manual.
|
|
.IP
|
|
Entry/exit points are displayed as numbers along the border of the
|
|
radar screen. Planes will enter the arena from these points without
|
|
warning. These points have a direction associated with them, and
|
|
planes will always enter the arena from this direction. On the
|
|
ascii version of
|
|
.I atc,
|
|
this direction is not displayed. It will become apparent
|
|
what this direction is as the game progresses.
|
|
.IP
|
|
Incoming planes will always enter at the same altitude: 7000 feet.
|
|
For a plane to successfully depart through an entry/exit point,
|
|
it must be flying at 9000 feet.
|
|
It is not necessary for the planes to be flying in any particular
|
|
direction when they leave the arena (yet).
|
|
.SS "INFORMATION AREA"
|
|
.IP
|
|
The second area of the display is the information area, which lists
|
|
the time (number of updates since start), and the number of planes you
|
|
have directed safely out of the arena.
|
|
Below this is a list of planes currently in the air, followed by a
|
|
blank line, and then a list of planes on the ground (at airports).
|
|
Each line lists the plane name and its current altitude,
|
|
an optional asterisk indicating low fuel, the plane's destination,
|
|
and the plane's current command. Changing altitude is not considered
|
|
to be a command and is therefore not displayed. The following are
|
|
some possible information lines:
|
|
.IP
|
|
B4*A0: Circle @ b1
|
|
.br
|
|
g7 E4: 225
|
|
.IP
|
|
The first example shows a prop plane named 'B' that is flying at 4000
|
|
feet. It is low on fuel (note the '*'). It's destination is
|
|
Airport #0.
|
|
The next command it expects
|
|
to do is circle when it reaches Beacon #1.
|
|
The second example shows a jet named 'g' at 7000 feet, destined for
|
|
Exit #4. It is just now executing a turn to 225 degrees (South-West).
|
|
.SS "INPUT AREA"
|
|
.IP
|
|
The third area of the display is the input area. It is here that
|
|
your input is reflected. See the INPUT heading of this manual
|
|
for more details.
|
|
.SS "AUTHOR AREA"
|
|
.IP
|
|
This area is used simply to give credit where credit is due. :-)
|
|
.SH INPUT
|
|
.LP
|
|
A command completion interface is built into
|
|
the game. At any time, typing '?' will list possible input characters.
|
|
Typing a backspace (your erase character) backs up, erasing the last part
|
|
of the command. When a command is complete, a return enters it, and
|
|
any semantic checking is done at that time. If no errors are detected,
|
|
the command is sent to the appropriate plane. If an error is discovered
|
|
during the check, the offending statement will be underscored and a
|
|
(hopefully) descriptive message will be printed under it.
|
|
.LP
|
|
The command syntax is broken into two parts:
|
|
.I "Immediate Only"
|
|
and
|
|
.I Delayable
|
|
commands.
|
|
.I "Immediate Only"
|
|
commands happen on the next
|
|
update.
|
|
.I Delayable
|
|
commands also happen on the next update unless they
|
|
are followed by an optional predicate called the
|
|
.I Delay
|
|
command.
|
|
.LP
|
|
In the following tables, the syntax
|
|
.B [0\-9]
|
|
means any single digit, and
|
|
.B <dir>
|
|
refers to the keys around the 's' key, namely ``wedcxzaq''.
|
|
In absolute references, 'q' refers to North-West or 315 degrees, and 'w'
|
|
refers to North, or 0 degrees.
|
|
In relative references, 'q' refers to -45 degrees or 45 degrees left, and 'w'
|
|
refers to 0 degrees, or no change in direction.
|
|
.LP
|
|
All commands start with a plane letter. This indicates the recipient
|
|
of the command. Case is ignored.

.SS "MARKING, UNMARKING AND IGNORING"
|
|
.LP
|
|
Planes are
|
|
.B marked
|
|
when they enter the arena. This means they are displayed in highlighted
|
|
mode on the radar display. A plane may also be either
|
|
.B unmarked
|
|
or
|
|
.B ignored.
|
|
An
|
|
.B unmarked
|
|
plane is drawn in unhighlighted mode, and a line of dashes is displayed in
|
|
the command field of the information area. The plane will remain this
|
|
way until a mark command has been issued. Any other command will be issued,
|
|
but the command line will return to a line of dashes when the command
|
|
is completed.
|
|
.LP
|
|
An
|
|
.B ignored
|
|
plane is treated the same as an unmarked plane, except that it will
|
|
automatically switch to
|
|
.B marked
|
|
status when a delayed command has been processed. This is useful if
|
|
you want to forget about a plane for a while, but its flight path has
|
|
not yet been completely set.
|
|
.LP
|
|
As with all of the commands, marking, unmarking and ignoring will take effect
|
|
at the beginning of the next update. Do not be surprised if the plane does
|
|
not immediately switch to unhighlighted mode.

.SH "NEW GAMES"
|
|
.LP
|
|
The
|
|
.B Game_List
|
|
file lists the currently available play fields. New field description
|
|
file names must be placed in this file to be 'playable'. If a player
|
|
specifies a game not in this file, his score will not be logged.
|
|
.LP
|
|
The game field description files are broken into two parts. The first
|
|
part is the definition section. Here, the four tunable game parameters
|
|
must be set. These variables are set with the syntax:
|
|
.IP
|
|
variable = number;
|
|
.LP
|
|
Variable may be one of:
|
|
.B update,
|
|
indicating the number of seconds between forced updates;
|
|
.B newplane,
|
|
indicating (about) the number of updates between new plane entries;
|
|
.B width,
|
|
indicating the width of the play field; and
|
|
.B height,
|
|
indicating the height of the play field.
|
|
.LP
|
|
The second part of the field description files describes the locations
|
|
of the exits, the beacons, the airports and the lines.
|
|
The syntax is as follows:
|
|
.IP
|
|
beacon: (x y) ... ;
|
|
.br
|
|
airport: (x y direction) ... ;
|
|
.br
|
|
exit: (x y direction) ... ;
|
|
.br
|
|
line: [ (x1 y1) (x2 y2) ] ... ;
|
|
.LP
|
|
For beacons, a simple x, y coordinate pair is used (enclosed in parenthesis).
|
|
Airports and exits require a third value, a direction, which is one
|
|
of
|
|
.B wedcxzaq.
|
|
For airports, this is the direction that planes must be going to take
|
|
off and land, and for exits, this is the direction that planes will going
|
|
when they
|
|
.B enter
|
|
the arena. This may not seem intuitive, but as there is no restriction on
|
|
direction of exit, this is appropriate.
|
|
Lines are slightly different, since they need two coordinate pairs to
|
|
specify the line endpoints. These endpoints must be enclosed in
|
|
square brackets.
|
|
.LP
|
|
All statements are semi-colon (;) terminated. Multiple item statements
|
|
accumulate. Each definition must occur exactly once, before any
