14: .SH NAME
15: atc \- Air Traffic Controller Game
16: .SH SYNOPSIS
17: .B atc
18: -[u?lstp] [-[gf] game_name] [-r random seed]
19: .SH DESCRIPTION
20: .LP
21: .I Atc
22: lets you try your hand at the nerve wracking duties of the air traffic
23: controller without endangering the lives of millions of
24: travelers each year.
25: Your responsibilities require you to direct the flight of jets
26: and prop planes into and out of the flight arena and airports.
27: The speed (update time) and frequency of the planes depend on the
28: difficulty of the chosen arena.
29: .SH OPTIONS
30: .LP
31: .TP 8
32: .B \-u

52: .I atc
53: expects to find its private files. This is used during the
54: installation of the program.
55: .TP
56: .B "\-g game"
57: Play the named game. If the game listed is not one of the
58: ones printed from the
59: .B \-l
60: option, the default game is played.
61: .TP

64: .B \-g.
65: .TP
66: .B "\-r seed"
67: Set the random seed. The purpose of this flag is questionable.
68: .SH GOALS
69: .LP
70: Your goal in
71: .I atc
72: is to keep the game going as long as possible.
73: There is no winning state, except to beat the times of other players.
74: You will need to: launch planes at airports (by instructing them to
75: increase their altitude); land planes at airports (by instructing them to
76: go to altitude zero when exactly over the airport); and maneuver planes
77: out of exit points.
78: .LP
79: Several things will cause the end of the game.
80: Each plane has a destination (see information area), and
81: sending a plane to the wrong destination is an error.
82: Planes can run out of fuel, or can collide. Collision is defined as
83: adjacency in any of the three dimensions. A plane leaving the arena
84: in any other way than through its destination exit is an error as well.
85: .LP
86: Scores are sorted in order of the number of planes safe. The other
87: statistics are provided merely for fun. There is no penalty for
88: taking longer than another player (except in the case of ties).
89: .LP
90: Suspending a game is not permitted. If you get a talk message, tough.
91: When was the last time an Air Traffic Controller got called away to
92: the phone?
93: .SH "THE DISPLAY"
94: .LP
95: Depending on the terminal you run
96: .I atc
97: on, the screen will be divided into 4 areas.
98: It should be stressed that the terminal driver portion of the
99: game was designed to be reconfigurable, so the display format can vary
100: depending the version you are playing. The descriptions here are based
101: on the ascii version
102: of the game. The game rules and input format, however,
103: should remain consistent.
104: Control-L redraws the screen, should it become muddled.
105: .SS RADAR
106: .IP
107: The first screen area is the radar display, showing the relative locations
108: of the planes, airports, standard entry/exit points, radar
109: beacons, and "lines" which simply serve to aid you in guiding
110: the planes.
111: .IP
112: Planes are shown as a single letter with an altitude. If
113: the numerical altitude is a single digit, then it represents
114: thousands of feet.
115: Some distinction is made between the prop
116: planes and the jets. On ascii terminals, prop planes are
117: represented by a upper case letter, jets by a lower case letter.
118: .IP
119: Airports are shown as a number and some indication of the direction
120: planes must be going to land at the airport.
121: On ascii terminals, this is one of '^', '>', '<', and 'v', to indicate
122: north (0 degrees), east (90), west (270) and south (180), respectively.
123: The planes will also
124: take off in this direction.
125: .IP
126: Beacons are represented as circles or asterisks and a number.
127: Their purpose is to offer a place of easy reference to the plane pilots.
128: See 'the delay command' under the input section of this manual.
129: .IP
130: Entry/exit points are displayed as numbers along the border of the
131: radar screen. Planes will enter the arena from these points without
132: warning. These points have a direction associated with them, and
133: planes will always enter the arena from this direction. On the
134: ascii version of
135: .I atc,
136: this direction is not displayed. It will become apparent
137: what this direction is as the game progresses.
138: .IP
139: Incoming planes will always enter at the same altitude: 7000 feet.
140: For a plane to successfully depart through an entry/exit point,
141: it must be flying at 9000 feet.
142: It is not necessary for the planes to be flying in any particular
143: direction when they leave the arena (yet).
144: .SS "INFORMATION AREA"
145: .IP
146: The second area of the display is the information area, which lists
147: the time (number of updates since start), and the number of planes you
148: have directed safely out of the arena.
149: Below this is a list of planes currently in the air, followed by a
150: blank line, and then a list of planes on the ground (at airports).
151: Each line lists the plane name and its current altitude,
152: an optional asterisk indicating low fuel, the plane's destination,
153: and the plane's current command. Changing altitude is not considered
154: to be a command and is therefore not displayed. The following are
155: some possible information lines:
156: .IP
157: B4*A0: Circle @ b1
158: .br
159: g7 E4: 225
160: .IP
161: The first example shows a prop plane named 'B' that is flying at 4000
162: feet. It is low on fuel (note the '*'). It's destination is
163: Airport #0.
164: The next command it expects
165: to do is circle when it reaches Beacon #1.
166: The second example shows a jet named 'g' at 7000 feet, destined for
167: Exit #4. It is just now executing a turn to 225 degrees (South-West).
168: .SS "INPUT AREA"
169: .IP
170: The third area of the display is the input area. It is here that
171: your input is reflected. See the INPUT heading of this manual
172: for more details.
173: .SS "AUTHOR AREA"
174: .IP
175: This area is used simply to give credit where credit is due. :-)
176: .SH INPUT
177: .LP
178: A command completion interface is built into
179: the game. At any time, typing '?' will list possible input characters.
180: Typing a backspace (your erase character) backs up, erasing the last part
181: of the command. When a command is complete, a return enters it, and
182: any semantic checking is done at that time. If no errors are detected,
183: the command is sent to the appropriate plane. If an error is discovered
184: during the check, the offending statement will be underscored and a
185: (hopefully) descriptive message will be printed under it.
186: .LP
187: The command syntax is broken into two parts:
188: .I "Immediate Only"
189: and
190: .I Delayable
191: commands.
192: .I "Immediate Only"
193: commands happen on the next
194: update.
195: .I Delayable
196: commands also happen on the next update unless they
197: are followed by an optional predicate called the
198: .I Delay
199: command.
200: .LP
201: In the following tables, the syntax
202: .B [0\-9]
203: means any single digit, and
204: .B <dir>
205: refers to the keys around the 's' key, namely ``wedcxzaq''.
206: In absolute references, 'q' refers to North-West or 315 degrees, and 'w'
207: refers to North, or 0 degrees.
208: In relative references, 'q' refers to -45 degrees or 45 degrees left, and 'w'
209: refers to 0 degrees, or no change in direction.
210: .LP
211: All commands start with a plane letter. This indicates the recipient
212: of the command. Case is ignored.

386: .SS "MARKING, UNMARKING AND IGNORING"
387: .LP
388: Planes are
389: .B marked
390: when they enter the arena. This means they are displayed in highlighted
391: mode on the radar display. A plane may also be either
392: .B unmarked
393: or
394: .B ignored.
395: An
396: .B unmarked
397: plane is drawn in unhighlighted mode, and a line of dashes is displayed in
398: the command field of the information area. The plane will remain this
399: way until a mark command has been issued. Any other command will be issued,
400: but the command line will return to a line of dashes when the command
401: is completed.
402: .LP
403: An
404: .B ignored
405: plane is treated the same as an unmarked plane, except that it will
406: automatically switch to
407: .B marked
408: status when a delayed command has been processed. This is useful if
409: you want to forget about a plane for a while, but its flight path has
410: not yet been completely set.
411: .LP
412: As with all of the commands, marking, unmarking and ignoring will take effect
413: at the beginning of the next update. Do not be surprised if the plane does
414: not immediately switch to unhighlighted mode.

447: .SH "NEW GAMES"
448: .LP
449: The
450: .B Game_List
451: file lists the currently available play fields. New field description
452: file names must be placed in this file to be 'playable'. If a player
453: specifies a game not in this file, his score will not be logged.
454: .LP
455: The game field description files are broken into two parts. The first
456: part is the definition section. Here, the four tunable game parameters
457: must be set. These variables are set with the syntax:
458: .IP
459: variable = number;
460: .LP
461: Variable may be one of:
462: .B update,
463: indicating the number of seconds between forced updates;
464: .B newplane,
465: indicating (about) the number of updates between new plane entries;
466: .B width,
467: indicating the width of the play field; and
468: .B height,
469: indicating the height of the play field.
470: .LP
471: The second part of the field description files describes the locations
472: of the exits, the beacons, the airports and the lines.
473: The syntax is as follows:
474: .IP
475: beacon: (x y) ... ;
476: .br
477: airport: (x y direction) ... ;
478: .br
479: exit: (x y direction) ... ;
480: .br
481: line: [ (x1 y1) (x2 y2) ] ... ;
482: .LP
483: For beacons, a simple x, y coordinate pair is used (enclosed in parenthesis).
484: Airports and exits require a third value, a direction, which is one
485: of
486: .B wedcxzaq.
487: For airports, this is the direction that planes must be going to take
488: off and land, and for exits, this is the direction that planes will going
489: when they
490: .B enter
491: the arena. This may not seem intuitive, but as there is no restriction on
492: direction of exit, this is appropriate.
493: Lines are slightly different, since they need two coordinate pairs to
494: specify the line endpoints. These endpoints must be enclosed in
495: square brackets.
496: .LP
497: All statements are semi-colon (;) terminated. Multiple item statements
498: accumulate. Each definition must occur exactly once, before any
499: item statements. Comments begin with a hash (#) symbol
500: and terminate with a newline.
501: The coordinates are between zero and width-1 and height-1
502: inclusive. All of the exit coordinates must lie on the borders, and
503: all of the beacons and airports must lie inside of the borders.
504: Line endpoints may be anywhere within the field, so long as
505: the lines are horizontal, vertical or
506: .B "exactly diagonal."
