If you want to modify this program in any way other 13 * than normal configuration changes, common decency would suggest 14 * that you also modify the name of the program so that my good name 15 * (what there is of it) is not impugned. (Calling it something like 16 * "warpx" or "superwarp" would be fine.) Also, give it another 17 * WARPDIR so that the scoreboards don't get confused. 18 * 19 * version 5.0 04/20/83 20 * 5.1 05/05/83 various tidbits 21 * 5.2 05/12/83 VAX -> vax, ifdef'ed a SIGCONT 22 * 5.3 05/24/83 RCS 23 * 24 * Log: warp.c,v 25 * Revision 7.0.1.3 86/12/12 17:07:44 lwall 26 * Baseline for net release. 27 * 28 * Revision 7.0.1.2 86/10/20 12:08:00 lwall 29 * Made all exits reset tty. 30 * 31 * Revision 7.0.1.1 86/10/16 10:54:13 lwall 32 * Added Damage. Fixed random bugs. 33 * 34 * Revision 7.0 86/10/08 15:14:47 lwall 35 * Split into separate files. Added amoebas and pirates. 36 * 37 * Revision 6.4 83/12/16 13:11:45 lwall 38 * Handled 15 bit random number generators. 39 * 40 * Fixed array overflow bug on multiple zaps. 41 * 42 * Multiple zaps now consolidated to minimize output. 43 * 44 * Tholian jackpot games outlawed under difficulty 15. 45 * 46 * Revision 6.3 83/08/24 11:17:49 lwall 47 * Fixed array overflow bug on multiple zap. 48 * 49 * Revision 6.2 83/08/23 18:06:37 lwall 50 * Added zap command. 51 * Warp -s should now work on dumb terminals 52 * Specifying difficulty >= 40 now just makes it a special game. 53 * SIGTTOU #ifdef'ed. 54 * No-delay read provided as alternative to FIONREAD. 55 * Warp won't report "-1 obsolete" when there are no Enterprises left. 56 * Some high-difficulty tuning. 57 * 58 * Revision 6.1 83/08/17 08:49:03 lwall 59 * Fixed obscure bug in storing UP that caused a %. in CM to occasionally 60 * foist garbage onto the screen. 61 * 62 * Revision 6.0 83/08/08 17:09:26 lwall 63 * New baseline version for net release. 64 * 65 * Revision 5.5 83/08/01 10:59:56 lwall 66 * Cloaking for the Enterprise. 67 * Difficulty now goes to 99, and many activities depending on difficulty 68 * have been adjusted in frequency. 69 * Simplified exit sequence, and reduced dependencies on control 70 * characters. You needn't see the scoreboard if you don't want to. 71 * Hitting i,w,c, or v switches to Enterprise. Hitting p switches to Base. 72 * Excessive use of q is not allowed. 73 * Excessive use of D is not allowed. 74 * Scoreboard may depend on either full name or login name. 75 * Integrated scoreboard lister. Login name now shows up on scoreboard. 76 * "Hidden" startup options are now upper case. 77 * Checks upon startup for no cursor movement, or screen too small. 78 * Checks upon startup that WARPDIR is correctly protected, and that warp 79 * is running setuid. As an additional bonus this prevents root from 80 * running warp, which mucks things up, UN*X be blessed. 81 * All gets's turned into fgets's for safety. 82 * Bonus Enterprises and Bases. 83 * Escalating bonuses for saving Base and Enterprise. 84 * Escalating Enterprise energy. 85 * Turbolasers decrease with distance. 86 * Really smart enemies can see through stars occasionally. 87 * Occasional Tholian jackpot waves. Tholians are a trifle nastier. 88 * Choleric Gorns. 89 * An O or o can miss seeing you. Enemies can avoid a stationary O, o, or X. 90 * Warp 3 enemies and other nastinesses are possible in massacre mode. 91 * Enemies that decide to navigate when they see you can do other things than 92 * just come toward you. 93 * Gorns occasionally launch a salvo for the fun of it. 94 * Only star and enemy explosions can keep the round going now. 95 * Bounces don't always go back to starting spot now. 96 * Better full name processing. USG quirks handled. & substitution also 97 * handled now (whoever dreamed up that one must have been in the middle 98 * of the night before the morning after). 99 * Catch ^D on fgets. 100 * Version number printer. 101 * Less signal catching during debugging. 102 * 103 * Revision 5.4 83/06/24 09:28:38 lwall 104 * 16 bit random number generators are now supported. 105 * Made warp not blow up on a null save file. 106 * Warp now prints E and B before the stars. 107 * Fixed bug which caused torp count to get decremented even when no torp 108 * was launched because of an obstacle. 109 * Put %<n>ld formats where appropriate. 110 * Fixed E: 0 0 bug on refresh. 111 * 112 * Revision 5.3 83/05/24 14:03:10 lwall 113 * Starting RCS 114 * 115 */ 116 117 #include "INTERN.h" 118 #include "warp.h" 119 #include "EXTERN.h" 120 #include "bang.h" 121 #include "init.h" 122 #include "intrp.h" 123 #include "object.h" 124 #include "move.h" 125 #include "play.h" 126 #include "score.h" 127 #include "sig.h" 128 #include "term.h" 129 #include "them.h" 130 #include "us.h" 131 #include "util.h" 132 #include "version.h" 133 #include "weapon.h" 134 135 main(argc,argv) 136 int argc;
