INSTRUCTIONS:
<*> = ENTERPRISE
+++ = KLINGON
>!< = STARBASE
* = STAR
COMMAND 0 = WARP ENGINE CONTROL
'COURSE' IS IN A CIRCULAR NUMERICAL 4 3 2
VECTOR ARRANGEMENT AS SHOWN. \ ^ /
INTERGER AND REAL VALUES MAY BE \^/
USED. THEREFORE COURSE 1.5 IS 5 ----- 1
HALF WAY BETWEEN 1 AND 2. /^\
/ ^ \
A VECTOR OF 9 IS UNDEFINED, BUT 6 7 8
VALUES MAY APPROACH 9.
COURSE
ONE 'WARP FACTOR' IS THE SIZE OF
ONE QUADRANT. THEREFORE TO GET
FROM QUADRANT 6,5 TO 5,5 YOU WOULD
USE COURSE 3, WARP FACTOR 1
COMMAND 1 = SHORT RANGE SENSOR SCAN
PRINTS THE QUADRANT YOU ARE CURRENTLY IN, INCLUDING
STARS, KLINGONS, STARBASES, AND THE ENTERPRISE; ALONG
WITH OTHER PERTINATE INFORMATION.
COMMAND 2 = LONG RANGE SENSOR SCAN
SHOWS CONDITIONS IN SPACE FOR ONE QUADRANT ON EACH SIDE
OF THE ENTERPRISE IN THE MIDDLE OF THE SCAN. THE SCAN
IS CODED IN THE FORM XXX, WHERE THE UNITS DIGIT IS THE
NUMBER OF STARS, THE TENS DIGIT IS THE NUMBER OF STAR-
BASES, THE HUNDREDS DIGIT IS THE NUMBER OF KLINGONS.
COMMAND 3 = PHASER CONTROL
ALLOWS YOU TO DESTROY THE KLINGONS BY HITTING HIM WITH
SUITABLY LARGE NUMBERS OF ENERGY UNITS TO DEPLETE HIS
SHIELD POWER. KEEP IN MIND THAT WHEN YOU SHOOT AT
HIM, HE'S GOING TO DO IT TO YOU TOO.
COMMAND 4 = PHOTON TORPEDO CONTROL
COURSE IS THE SAME AS USED IN WARP ENGINE CONTROL
IF YOU HIT THE KLINGON, HE IS DESTROYED AND CANNOT FIRE
BACK AT YOU. IF YOU MISS, HE WILL SHOOT HIS PHASERS AT
YOU.
NOTE: THE LIBRARY COMPUTER (COMMAND 7) HAS AN OPTION
TO COMPUTE TORPEDO TRAJECTORY FOR YOU (OPTION 2).
COMMAND 5 = SHIELD CONTROL
DEFINES NUMBER OF ENERGY UNITS TO BE ASSIGNED TO SHIELDS
ENERGY IS TAKEN FROM TOTAL SHIP'S ENERGY.
COMMAND 6 = DAMAGE CONTROL REPORT
GIVES STATE OF REPAIRS OF ALL DEVICES. A STATE OF REPAIR
LESS THAN ZERO SHOWS THAT THAT DEVICE IS TEMPORARILY
DAMAGED.
COMMAND 7 = LIBRARY COMPUTER
THE LIBRARY COMPUTER CONTAINS THREE OPTIONS:
OPTION 0 = CUMULATIVE GALACTIC RECORD
SHOWS COMPUTER MEMORY OF THE RESULTS OF ALL PREVIOUS
LONG RANGE SENSOR SCANS
OPTION 1 = STATUS REPORT
SHOWS NUMBER OF KLINGONS, STARDATES AND STARBASES
LEFT.
OPTION 2 = PHOTON TORPEDO DATA
GIVES TRAJECTORY AND DISTANCE BETWEEN THE ENTERPRISE
AND ALL KLINGONS IN YOUR QUADRANT
Since this is a hobby project and I'm learning Elm, for reasons of insecurity and hubris I likely won't take any external pull requests.
- The original BASIC code for this game can be found here. Thanks for existing and giving me purpose.
- Thanks to the Elm Language for making a typed programming language that is appealing to learn.
