.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
|
||||
Print the usage line and exit.
|
||||
.TP
|
||||
.B \-?
|
||||
Same as
|
||||
.B \-u.
|
||||
.TP
|
||||
.B \-l
|
||||
Print a list of available games and exit.
|
||||
The first game name printed is the default game.
|
||||
.TP
|
||||
.B \-s
|
||||
Print the score list (formerly the Top Ten list).
|
||||
.TP
|
||||
.B \-t
|
||||
Same as
|
||||
.B \-s.
|
||||
.TP
|
||||
.B \-p
|
||||
Print the path to the special directory where
|
||||
.I atc
|
||||
expects to find its private files. This is used during the
|
||||
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 "\-f game"
|
||||
Same as
|
||||
.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 all 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.

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
|
||||
item statements. Comments begin with a hash (#) symbol
|
||||
and terminate with a newline.
|
||||
The coordinates are between zero and width-1 and height-1
|
||||
inclusive. All of the exit coordinates must lie on the borders, and
|
||||
all of the beacons and airports must lie inside of the borders.
|
||||
Line endpoints may be anywhere within the field, so long as
|
||||
the lines are horizontal, vertical or
|
||||
.B "exactly diagonal."

The screen sometimes refreshes after you have quit.

Yet Another Curses Bug was discovered during the development of this game.
|
||||
If your curses library clrtobot.o is version 5.1 or earlier,
|
||||
you will have erase problems with the backspace operator in the input
|

window.

*
|
||||
* MOVE LIBRARY
|
||||
*
|
||||
* This set of subroutines moves a cursor to a predefined
|
||||
* location, independent of the terminal type. If the
|
||||
* terminal has an addressable cursor, it uses it. If
|
||||
* not, it optimizes for tabs (currently) even if you don't
|
||||
* have them.
|
||||
*
|
||||
* At all times the current address of the cursor must be maintained,
|
||||
* and that is available as structure cursor.
|
||||
*
|
||||
* The following calls are allowed:
|
||||
* move(sp) move to point sp.
|
||||
* up() move up one line.
|
||||
* down() move down one line.
|
||||
* bs() move left one space (except column 0).
|
||||
* nd() move right one space(no write).
|
||||
* clear() clear screen.
|
||||
* home() home.
|
||||
* ll() move to lower left corner of screen.
|
||||
* cr() carriage return (no line feed).
|
||||
* pr() just like standard printf, but keeps track
|
||||
* of cursor position. (Uses pstring).
|
||||
* apr() same as printf, but first argument is &point.
|
||||
* (Uses pstring).
|
||||
* pstring(s) output the string of printing characters.
|
||||
* However, '\r' is interpreted to mean return
|
||||
* to column of origination AND do linefeed.
|
||||
* '\n' causes <cr><lf>.
|
||||
* putpad(str) calls tputs to output character with proper
|
||||
* padding.
|
||||
* outch() the output routine for a character used by
|
||||
* tputs. It just calls putchar.
|
||||
* pch(ch) output character to screen and update
|
||||
* cursor address (must be a standard
|
||||
* printing character). WILL SCROLL.
|
||||
* pchar(ps,ch) prints one character if it is on the
|
||||
* screen at the specified location;
|
||||
* otherwise, dumps it.(no wrap-around).
|
||||
*
|
||||
* getcap() initializes strings for later calls.
|
||||
* cap(string) outputs the string designated in the termcap
|
||||
* data base. (Should not move the cursor.)
|
||||
* done() returns the terminal to intial state and exits.
|
||||
*
|
||||
* point(&p,x,y) return point set to x,y.
|
||||
*
|
||||
* delay(t) causes an approximately constant delay
|
||||
* independent of baudrate.
|
||||
* Duration is ~ t/20 seconds.
