   3 sst.py =-- Super Star Trek in Python
   4
   5 This code is a Python translation of a C translation of a FORTRAN
   6 original dating back to 1973.  Beautiful Python it is not.  But it
   7 works.
   8
   9 Dave Matuszek says:
  10
  11 SRSCAN, MOVE, PHASERS, CALL, STATUS, IMPULSE, PHOTONS, ABANDON,
  12 LRSCAN, WARP, SHIELDS, DESTRUCT, CHART, REST, DOCK, QUIT, and DAMAGE
  13 were in the original non-"super" version of UT FORTRAN Star Trek.
  14
  15 Tholians were not in the original. Dave is dubious about their merits.
  16 (They are now controlled by OPTION_THOLIAN and turned off if the game
  17 type is "plain".)
  18
  19 Planets and dilithium crystals were not in the original.  Dave is OK
  20 with this idea. (It's now controlled by OPTION_PLANETS and turned
  21 off if the game type is "plain".)
  22
  23 Dave says the bit about the Galileo getting turned into a
  24 McDonald's is "consistant with our original vision".  (This has been
  25 left permanently enabled, as it can only happen if OPTION_PLANETS
  26 is on.)
  27
  28 Dave also says the Space Thingy should not be preserved across saved
  29 games, so you can't prove to others that you've seen it.  He says it
  30 shouldn't fire back, either.  It should do nothing except scream and
  31 disappear when hit by photon torpedos.  It's OK that it may move
  32 when attacked, but it didn't in the original.  (Whether the Thingy
  33 can fire back is now controlled by OPTION_THINGY and turned off if the
  34 game type is "plain" or "almy".  The no-save behavior has been restored.)
  35
  36 The Faerie Queen, black holes, and time warping were in the original.
  37
  38 Here are Tom Almy's changes:
  39
  40 In early 1997, I got the bright idea to look for references to
  41 "Super Star Trek" on the World Wide Web. There weren't many hits,
  42 but there was one that came up with 1979 Fortran sources! This
  43 version had a few additional features that mine didn't have,
  44 however mine had some feature it didn't have. So I merged its
  45 features that I liked. I also took a peek at the DECUS version (a
  46 port, less sources, to the PDP-10), and some other variations.
  47
  48 1, Compared to the original UT version, I've changed the "help"
  49 command to "call" and the "terminate" command to "quit" to better
  50 match user expectations. The DECUS version apparently made those
  51 changes as well as changing "freeze" to "save". However I like
  52 "freeze".  (Both "freeze" and "save" work in SST2K.)
  53
  54 2. The experimental deathray originally had only a 5% chance of
  55 success, but could be used repeatedly. I guess after a couple
  56 years of use, it was less "experimental" because the 1979
  57 version had a 70% success rate. However it was prone to breaking
  58 after use. I upgraded the deathray, but kept the original set of
  59 failure modes (great humor!).  (Now controlled by OPTION_DEATHRAY
  60 and turned off if game type is "plain".)
  61
  62 3. The 1979 version also mentions srscan and lrscan working when
  63 docked (using the starbase's scanners), so I made some changes here
  64 to do this (and indicating that fact to the player), and then realized
  65 the base would have a subspace radio as well -- doing a Chart when docked
  66 updates the star chart, and all radio reports will be heard. The Dock
  67 command will also give a report if a base is under attack.
  68
  69 4. Tholian Web from the 1979 version.  (Now controlled by
  70 OPTION_THOLIAN and turned off if game type is "plain".)
  71
  72 5. Enemies can ram the Enterprise. (Now controlled by OPTION_RAMMING
  73 and turned off if game type is "plain".)
  74
  75 6. Regular Klingons and Romulans can move in Expert and Emeritus games.
  76 This code could use improvement. (Now controlled by OPTION_MVBADDY
  77 and turned off if game type is "plain".)
  78
  79 7. The deep-space probe feature from the DECUS version.  (Now controlled
  80 by OPTION_PROBE and turned off if game type is "plain").
  81
  82 8. 'emexit' command from the 1979 version.
  83
  84 9. Bugfix: Klingon commander movements are no longer reported if long-range
  85 sensors are damaged.
  86
  87 10. Bugfix: Better base positioning at startup (more spread out).
  88 That made sense to add because most people abort games with
  89 bad base placement.
  90
  91 In June 2002, I fixed two known bugs and a documentation typo.
  92 In June 2004 I fixed a number of bugs involving: 1) parsing invalid
  93 numbers, 2) manual phasers when SR scan is damaged and commander is
  94 present, 3) time warping into the future, 4) hang when moving
  95 klingons in crowded quadrants.  (These fixes are in SST2K.)
  96
  97 Here are Stas Sergeev's changes:
  98
  99 1. The Space Thingy can be shoved, if you ram it, and can fire back if
 100 fired upon. (Now controlled by OPTION_THINGY and turned off if game
 101 type is "plain" or "almy".)
 102
 103 2. When you are docked, base covers you with an almost invincible shield.
 104 (A commander can still ram you, or a Romulan can destroy the base,
 105 or a SCom can even succeed with direct attack IIRC, but this rarely
 106 happens.)  (Now controlled by OPTION_BASE and turned off if game
 107 type is "plain" or "almy".)
 108
 109 3. Ramming a black hole is no longer instant death.  There is a
 110 chance you might get timewarped instead. (Now controlled by
 111 OPTION_BLKHOLE and turned off if game type is "plain" or "almy".)
 112
 113 4. The Tholian can be hit with phasers.
 114
 115 5. SCom can't escape from you if no more enemies remain
 116 (without this, chasing SCom can take an eternity).
 117
 118 6. Probe target you enter is now the destination quadrant. Before I don't
 119 remember what it was, but it was something I had difficulty using.
 120
 121 7. Secret password is now autogenerated.
 122
 123 8. "Plaque" is adjusted for A4 paper :-)
 124
 125 9. Phasers now tells you how much energy needed, but only if the computer
 126 is alive.
 127
 128 10. Planets are auto-scanned when you enter the quadrant.
 129
 130 11. Mining or using crystals in presense of enemy now yields an attack.
 131 There are other minor adjustments to what yields an attack
 132 and what does not.
 133
 134 12. "freeze" command reverts to "save", most people will understand this
 135 better anyway. (SST2K recognizes both.)
 136
 137 13. Screen-oriented interface, with sensor scans always up.  (SST2K
 138 supports both screen-oriented and TTY modes.)
 139
 140 Eric Raymond's changes:
 141
 142 Mainly, I translated this C code out of FORTRAN into C -- created #defines
 143 for a lot of magic numbers and refactored the heck out of it.
 144
 145 1. "sos" and "call" becomes "mayday", "freeze" and "save" are both good.
 146
 147 2. Status report now indicates when dilithium crystals are on board.
 148
 149 3. Per Dave Matuszek's remarks, Thingy state is never saved across games.
 150
 151 4. Added game option selection so you can play a close (but not bug-for-
 152 bug identical) approximation of older versions.
 153
 154 5. Half the quadrants now have inhabited planets, from which one
 155 cannot mine dilithium (there will still be the same additional number
 156 of dilithium-bearing planets).  Torpedoing an inhabited world is *bad*.
 157 There is BSD-Trek-like logic for Klingons to attack and enslave
 158 inhabited worlds, producing more ships (only is skill is 'good' or
 159 better). (Controlled by OPTION_WORLDS and turned off if game
 160 type is "plain" or "almy".)
 161
 162 6. User input is now logged so we can do regression testing.
 163
 164 7. More BSD-Trek features: You can now lose if your entire crew
 165 dies in battle.  When abandoning ship in a game with inhabited
 166 worlds enabled, they must have one in the quadrant to beam down
 167 to; otherwise they die in space and this counts heavily against
 168 your score.  Docking at a starbase replenishes your crew.
 169
 170 8. Still more BSD-Trek: we now have a weighted damage table.
 171 Also, the nav subsystem (enabling automatic course
 172 setting) can be damaged separately from the main computer (which
 173 handles weapons targeting, ETA calculation, and self-destruct).
 174
 175 After these features were added, I translated this into Python and added
 176 more:
 177
 178 9. A long-range scan is done silently whenever you call CHART; thus
 179 the LRSCAN command is no longer needed.  (Controlled by OPTION_AUTOSCAN
 180 and turned off if game type is "plain" or "almy".)
