VTTREK

VTTREK es un juego espacial para hasta 8 jugadores para TOPS-20. Está diseñado para las terminales DEC VT100 que tienen la Opción de Video Avanzado. Cada jugador juega en un terminal separada iniciada sesión en un trabajo separado.

El juego representa una batalla entre la Federación Unida de Planetas y el Imperio Klingon. El objetivo es expulsar al lado opuesto de la galaxia capturando planetas y destruyendo bases planetarias y naves enemigas.

El primer jugador en ejecutar el juego selecciona un juego de torneo o un juego aleatorio. En los juegos de torneo, la ubicación de los objetos es la misma de una carrera a otra. Para seleccionar un juego de torneo, ingrese un número del 1 al 9. Introduzca cualquier otro carácter para seleccionar un juego aleatorio.

Se muestra una lista de naves en el juego, seguida de una lista de naves disponibles. Seleccione la nave que desea controlar ingresando su inicial.

Si intenta ingresar al juego cuando otro jugador se está iniciando, es posible que se le pida que permanezca en espera hasta que el otro jugador termine.

Cada lado comienza con cuatro naves estelares y cuatro bases estelares. Las naves funcionan automáticamente hasta que un jugador ingresa al juego y toma el control de una de ellas. El jugador retiene el control hasta que abandona el juego o hasta que se destruye la nave.

Las naves que operan automáticamente realizan las funciones normales de las naves. Pueden atacar naves enemigas, capturar planetas y acudir en ayuda de otras naves. También pueden atacar bases enemigas cuando su bando controla más de ocho planetas.

Las bases estelares sirven como puntos de reabastecimiento de combustible para las naves, al igual que los planetas capturados. Las bases y los planetas capturados atacan a las naves enemigas e informan a las naves amigas cuando hay enemigos cerca.

Los planetas capturados buscan oportunidades para rebelarse. Cuantas menos bases y planetas controles, más probable es que tus planetas se te rebelen.

The ship you command is an object in three-dimensional space. You may rotate and move the ship anywhere in the galaxy.

The galaxy has no external reference grid. The location of an object in space is always given relative to the ship you command.

An object location is given as a bearing, an elevation, and a range. The bearing and elevation are simple spherical coordinates. Looking forward along the long axis of the ship, the bearing is the angle to the left or right (negative on the left, positive on the right) and the elevation is the angle up or down (negative is down, positive is TREK Version 2.0 Page 2

up). The range is the absolute distance from your ship to an object. See the diagram in Appendix A.

Each ship begins with 3000 units of ship energy and 2000 units of shield energy, although the total may be somewhat less at the time control is taken. Ship energy is expended when the ship is moved, when weapons are fired, or when energy is transferred from ship to ship. Shield energy is expended when the shields absorb hits from enemy weapons. The shields require at least 100 units of energy or they collapse. When shields are down the effect of enemy weapons is doubled. Energy loss continues until ship energy goes negative and the ship explodes.

Ships may be refueled at starbases or friendly planets. In emergencies energy may be transferred from ship to ship.

The warp engines move the ship forward or backward. The distance moved depends upon the warp factor. Initially, the distance is equal to 2 to the power of the warp factor. Warp 0 moves the ship 1 unit, warp 9 moves the ship 512 units. You can change the distances associated with the warp factors.

The energy cost is computed in milliunits equal to the distance squared.

The directional computer controls the orientation of the ship. It is activated whenever the ship is rotated. Changing the orientation of the ship changes the relative location of every other object in space.

The targeter controls, among other things, the direction of weapons fire and long range sensor scans. It is analogous to a gun turret that can be aimed in any direction relative to the ship. When the ship orientation changes the target orientation also changes, except when the target is locked on an object.

The ship has short range sensors that scan in every direction and long range sensors that scan in the target direction.

The library computer maintains a catalog of the last known positions of objects. The library represents a pool of information shared by all of the ships on a side. Initially the library contains the locations of your starbases and the ships on your side. Thereafter any object scanned by the sensors is automatically cataloged into the library. Stars and planetary interceptors are not cataloged.

The target list connects the sensors and the library with the targeter and the directional computer. The target list contains up to four objects obtained from either the sensors or the library. Coordinates from the list can be fed directly into the target and directional computers by referencing the number that precedes the list entry.

The ship is equipped with phasers and photon torpedoes. Both weapons apply energy to a target that must be absorbed by the target's shields. Phaser energy may be anything from 1 to 1000 units (default is 200 units). Torpedo energy is fixed at 200 units per torpedo.

Phasers have a maximum range of 1024 units. Torpedoes have a maximum range of 2048 units.

Phasers have a firing cost computed in milliunits equal to the phaser energy squared. In addition, there is a time delay in milliseconds equal to a hundredth of the firing cost to allow the phasers to cool and recharge. Torpedoes have a fixed launch cost of 20 units.

The viewer at the top of the screen displays the forward view into space along the long axis of the ship. The cursor in the center of the viewer is the 0,0 point for bearing and elevation measurements. If the target is within the range of the viewer but not at the center it is displayed as a second cursor.

The numbers along the top and bottom of the viewer frame are bearing angles. The numbers along the sides are elevation angles.

See Appendix B for a description of objects as they appear in the viewer.

The message area at the lower left contains a status line and a blank area for messages. The target list is displayed here. The status line contains displays for ship energy, shield energy and status, and warp factor. The shaded field is the command echo area.

The command keypad at the lower right corresponds to the VT100 numeric keypad.

There are immediate commands and common commands. Immediate commands are executed as soon as the command key is pressed. Common commands are executed when the EXE key is pressed. To repeat a command press the EXE key again.

  The four function keys at the top of the keypad activate the short
  range  sensor.  A short range scan scans space for any object of a
  given type within 1024 distance units of the ship, as follows:

          PF1  -  Scan for Federation starships and bases
          PF2  -  Scan for Klingon cruisers and bases
          PF3  -  Scan for planets and interceptors
          PF4  -  Scan for any of the above

  Note that stars are ignored by the short range sensors.

  The LR SCAN key activates the long range  sensor.   A  long  range
  scan scans at the target coordinates for the nearest object within
  2048 distance units.

The common command format is a command abbreviation followed by one, two, or no modifiers. The modifiers may be one or two numbers or a combination of a direction and a number.

The command abbreviation is one or two letters. If the abbreviation contains two letters, both must be entered. A command can also be entered from the keypad by pressing the appropriate keypad key.

Numbers, including the minus sign, can be entered from the keypad or from the main keyboard. Two numbers are separated by a period, a tab, or a space.

If two numbers represent bearing and elevation, the bearing is the first number, the elevation the second number.

Directions are entered using the arrow keys or the special function (PF) keys on the keypad. The PF keys are functionally identical to the arrow keys. You may enter direction and number or number and direction.

The keypad ERA key erases a single field.

The common commands are listed below:

AL LIST ALL OBJECTS IN THE LIBRARY

  Moves objects from the library to the  target  list  and  displays
  them four at a time.  If more than four objects are available, the
  keypad MOR key will flash.  Press the MOR  key  to  see  the  next
  group of four.

  PH ene    Fire phaser of given energy

PL LIST ALL PLANETS IN THE LIBRARY

Q QUIT (EXIT FROM THE GAME)

R CLEAR AND REDISPLAY THE SCREEN TREK Version 2.0 Page 7

RA SOUND RED ALERT

  RA, YA, SA, and AS relay your ship status to other ships  on  your
  side.   RA (red alert) and AS (request assistance) cause automatic
  ships to come to your aid.  If an automatic ship finds  you  in  a
  low  energy  state,  it  will  transfer energy to you.  YA (yellow
  alert) and SA (secure from alert) cancel RA and AS.

RE REFUEL AND RELOAD

  Ship must be within 512 units  of  starbase  or  friendly  planet.
  Refuel  rate  is  500  units  at  starbases, 250 units at planets.
  Reload rate is 5 torpedoes at starbases, 3 torpedoes at planets.

RF RAPID-FIRE WEAPONS

  Turns the keypad phaser and torpedo keys into immediate  commands.
  When  in  rapid  fire  mode,  pressing  the  phaser  key fires the
  phasers, pressing the torpedo key fires torpedos.   Phaser  energy
  up to 1000 and torpedo count up to 3 may be specified.  Default is
  200 unit phaser and 1 torpedo.  Enter RF alone to return to normal
  mode.

  RF ph to  Set rapid fire for given phasers and torpedos
  RF        Return to normal mode.

RO ROTATE THE SHIP

  Rotate the  ship  in  a  specific  direction,  or  in  the  target
  direction, or toward a listed object, or toward a specific bearing
  and elevation.  Rotation in a direction  may  be  followed  by  an
  angle.   If no angle is given, the targeter searches for an object
  in the given direction and the ship is rotated toward the  nearest
  object found.

  RO        Rotate in the target direction
  RO dir    Find a target and rotate toward it
  RO dir a  Rotate by an angle in a direction
  RO nbr    Rotate toward a listed object
  RO b e    Rotate toward a bearing and elevation

RT REFRESH WITH VT100 SELF-TEST

  Invokes  the  VT100  self-test  routine  and  then  refreshes  the
  display.   If  the  terminal  appears  to  be displaying the wrong
  characters, RT may correct the problem.

SA SECURE FROM ALERT (SEE RA)

SE SEND A MESSAGE

  Send a message to one or more ships.   Displays  initial  of  your
  ship and a colon in the message area.  Enter your message and type
  EXE to send.  Keypad ERA key cancels the command.

  SE ALL    Send to all ships
  SE F      Send to all Federation ships

  SE K      Send to all Klingon ships
  SE init   Send to ship with init as its initial

SH SET SHIELDS

  Raise  or  lower  shields.   Set  shields  to  a  specific  energy
  (difference is taken from or released to ship energy).

  SH up     Raise shields
  SH dn     Lower shields
  SH ene    Set shield energy

ST DISPLAY ACTIVE STATUS

  Displays  the  number  of  ships,  bases,  and  captured   planets
  available to each side.

TA SET THE TARGET

  Target on an object, or in  a  specific  direction,  or  toward  a
  bearing  and  elevation.   TA  followed by no modifiers causes the
  targeter to search the viewer for the object that  is  closest  to
  the  current  target  position.   TA with a direction but no angle
  restricts the search to  the  given  direction.   If  the  current
  target  position  is  not  within  range of the viewer, TA with no
  modifiers resets the target to 0,0.

  TA        Search for a target
  TA dir    Search for a target in a specific direction
  TA dir a  Move the target by an angle in a direction
  TA nbr    Set the target at a listed object
  TA b e    Set the target at a bearing and elevation

TO FIRE PHOTON TORPEDOES

  Fire from 1 to 3 torpedoes in the target direction.  Default is  1
  torpedo.

  TO        Fire one torpedo
  TO nbr    Fire a number of torpedoes

TR TRANSFER ENERGY TO ANOTHER SHIP

  Up  to  1000  units  of  ship  energy  may  be  transferred.   The
  transferring ship first targets on the receiving ship.  Both ships
  must have their shields down.  If the receiving ship  has  shields
  up, the shields will absorb the energy.

                        -Z(down)

Draw lines connecting the dots next to the following points:

  +X and -X        +Y and -Y        +Z and -Z
   O and P          O and A          P and A          A and B

The ship faces forward along line X. In the viewer, the line Z is up and down, the line Y is left to right.

The angles OBA, OAP, and PAB are right angles.

The object P is in the upper left of the viewer. Its bearing angle is the angle between lines OA and OB. Its elevation is the angle between lines OP and OA. Its range is the distance from point O to point P.

In this case P has a negative bearing (to the left of center) and a positive elevation (above center).

Objects are displayed in the viewer as follows:

  Federation starbase      O=O=O      ooo
  Klingon Starbase         8=8=8      ===
  Federation Starship      o-V-o      -v-
  Klingon Star Cruiser     o-0-o      -o-
  Planet                    (@)        o
  Interceptor               IoI        H
  Star                       *         *

The further away an object is, the smaller it becomes. All objects except stars eventually disappear.

The main difference between versions 1.0 and 2.0 is that all eight ships are active in version 2.0. In version 1.0 the only active ships were the players' ships. As a consequence, the objective of the game has changed in that it is officially over when all four ships on a side have been destroyed.

Another major difference is that a new queueing mechanism is used in version 2.0. The old routines sometimes caused illegal UUOs or lock-ups with LED L1 on. This shouldn't happen in version 2.0.

Other differences are that planets can rebel in version 2.0, you can set rapid-fire mode phaser energy and torpedo counts, messages are displayed at the bottom of the screen, and there are a few new commands. The ST command has changed its meaning from self-test to status. RT replaces it. Also, an option has been added that allows the KL version of the game to be compiled to run on KI's.
