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 int 136 main(int argc, char *argv[]) 137 { 138 char tmp, *s, *tcbuf; 139 140 FILE *savfil; 141 142 #if RANDBITS > 16 143 for (i=100; i; i--) 144 if (rand() >= 65536) 145 goto rand_ok; 146 printf("Recompile with RANDBITS = 15 or 16.\n"); 147 exit(1); 148 #else 149 #if RANDBITS > 15 150 for (i=100; i; i--) { 151 if (rand() >= 32768) 152 goto rand_ok; 153 } 154 printf("Recompile with RANDBITS = 15.\n"); 155 exit(1); 156 #endif 157 #endif 158 159 #ifdef lint /* to suppress "defined but never used" */ 160 # ifdef SIGTSTP 161 (void)stop_catcher(); 162 # endif 163 # ifdef SIGCONT 164 (void)cont_catcher(); 165 # endif 166 #endif 167 168 while (--argc > 0 && (*++argv)[0] == '-') 169 for (s = argv[0]+1; *s != '\0'; s++) 170 switch (*s) { 171 case '&': 172 amoebaspec = true; 173 beginner = true; 174 break; 175 case 'A': 176 apolspec = true; 177 beginner = true; 178 break; 179 case 'b': 180 beginner = true; 181 break; 182 case 'C': 183 crushspec = true; 184 beginner = true; 185 break; 186 case 'D': 187 debugging = true; 188 #ifdef DEBUGGING 189 debug = atoi(++s); 190 #endif 191 s += strlen(s)-1; 192 break; 193 case 'd': 194 s++; 195 if (*s == '=') s++; 196 ismarts = atoi(s); 197 if (ismarts <= 0) 198 ismarts = 1; 199 if (ismarts > 99) 200 ismarts = 99; 201 if (ismarts > 40) 202 beginner = true; 203 s += strlen(s)-1; 204 break; 205 case 'E': 206 klingspec = true; 207 beginner = true; 208 s++; 209 if (*s == '=') s++; 210 inumenemies = atoi(s); 211 s += strlen(s)-1; 212 break; 213 case 'F': 214 friendspec = true; 215 beginner = true; 216 s++; 217 if (*s == '=') s++; 218 inumfriends = atoi(s); 219 s += strlen(s)-1; 220 break; 221 case 'G': 222 gornspec = true; 223 beginner = true; 224 break; 225 case 'l': 226 lowspeed = true; 227 break; 228 case 'm': 229 metakey = true; 230 break; 231 case 'M': 232 massacre = true; 233 break; 234 case 'P': 235 piratespec = true; 236 beginner = true; 237 s++; 238 if (*s == '=') s++; 239 inumpirates = atoi(s); 240 s += strlen(s)-1; 241 break; 242 case 'S': 243 prespec = true; 244 beginner = true; 245 s++; 246 if (*s == '=') s++; 247 if (*s) 248 prescene = atoi(s); 249 else 250 prescene = -1; 251 s += strlen(s)-1; 252 break; 253 case 'R': 254 romspec = true; 255 beginner = true; 256 break; 257 case '*': 258 starspec = true; 259 beginner = true; 260 s++; 261 if (*s == '=') s++; 262 inumstars = atoi(s); 263 s += strlen(s)-1; 264 break; 265 case 's': 266 scorespec = true; 267 break; 268 case 'T': 269 tholspec = true; 270 beginner = true; 271 break; 272 case 'x': 273 experimenting = true; 274 break; 275 case 'v': 276 version(); 277 exit(0); 278 break; 279 default: 280 fprintf(stderr,"warp: illegal option %c\n", *s); 281 fprintf(stderr, "Usage: warp -dn -b -x -v -s\n"); 282 exit(1); 283 } 284 if (argc != 0) { 285 fprintf(stderr, "Usage: warp -dn -b -x -v -s\n"); 286 exit(1); 287 } 288 bang_init(); 289 move_init(); 290 object_init(); 291 play_init(); 292 them_init(); 293 us_init(); 294 util_init(); 295 weapon_init(); 296 297 tcbuf = malloc(1024); 298 intrp_init(tcbuf); 299 300 if (chdir(warplib) < 0) 301 fprintf(stderr,NOCD,warplib); 302 303 term_init(); 304 305 term_set(tcbuf); 306 free(tcbuf); 307 308 umask(022); /* mustn't rely on incoming umask--could be 033 which */ 309 /* would disable people from running wscore */ 310 311 score_init(); 312 313 sig_init(); 314 315 if (totalscore) { 316 clear(); 317 mvaddstr(12,25,"*** restoring saved game ***"); 318 roundsleep(1); 319 } 320 321 srand(getpid()); 322 323 do { 324 for (keepgoing = true;;) { 325 if (!experimenting) { 326 if ((savfil = fopen(savefilename,"w")) == NULL) { 327 resetty(); 328 printf("Can't open savefile `%s'\r\n", savefilename); 329 finalize(1); 330 } 331 fprintf(savfil, 332 "%-8s %10ld, %2d,%5d,%2d,%2d,%3d %c%c%c%c%c%c%c%c%c\n", 333 logname, totalscore, smarts, cumsmarts, 334 numents, numbases, wave, 335 apolspec ?
