This system permits lib staff to assign zone globals to areas. These zone flags
supplement room flags, but can be assigned in one line zone file command (i.e. Z
0 1 0 0) in order to cover an entire zone. This reduces the amount of work needed
in editing, and is provided as a prerequisite for the gladiatorial arena combat
snippet in the next post. Enjoy!

pkilling system defined by zone flags
added to wintermute in august 1998
sarq's zone flag system implemented

---------------------------------------------------------------------------------

killer toggle command

in interpreter.c, define:

ACMD(do_killer);

in interpreter.c, master command list, add:

  { "killer"   , POS_FIGHTING, do_killer   , 0, 0 },

in interpreter.c, append:

/* killer command for voluntary switching to the dark side, taerin 8/14/98 */
ACMD(do_killer)
{
  char buf2[128];

  if (IS_NPC(ch) || PLR_FLAGGED(ch, PLR_KILLER))
    return;

  SET_BIT(PLR_FLAGS(ch), PLR_KILLER);

  send_to_char("Cry Havoc! And let slip the dogs of war!\r\n", ch);
  send_to_char("Your move to the dark side is only reversed by: death or pardon.\r\n", ch);

  sprintf(buf2, "%s elects to become a PLAYER KILLER.", GET_NAME(ch));
  mudlog(buf2, BRF, LVL_IMMORT, TRUE);
}

in fight.c, void check_killer:
    send_to_char("Cry Havoc! And let slip the dogs of war!\r\n", ch);

----------------------------------------------------------------------------------

ZONE_FLAGS


utils.h:
  after line: /* basic bitvector utils ********************************/

  Add:
/* Sarq 8/21/98 - for New Z zone command */
#define IN_ZONE(ch) (world[(ch)->in_room].zone)
/* zonenumb should be IN_ZONE(ch) */
#define ZONE_NOPKILL(zone) (zone_flags[zone].NOPKILL)
#define ZONE_NOPORTAL(zone) (zone_flags[zone].NOPORTAL)



in structs.h:
  Before line: (roughly line 737) /* char-related structures *********************/

  Add:
/* zone-related structs ************************************8/21/98 by Sarq */

struct zone_flag_struct {
  /* if these are set to 1 during game, you can NOT do them in that zone */
  int NOPORTAL, NOPKILL;
};

typedef struct zone_flag_struct zf_struct;

zf_struct zone_flags[500]; /* If number of zones exceeds 500, this must increase */


in db.c, void reset_zone:

after:
  for (cmd_no = 0; ZCMD.command != 'S'; cmd_no++) {
add:
    if (ZCMD.command == 'Z') test_log("Z COMMAND FOUND"); /* 8/21/98 Sarq */

then at end:
    case 'Z':
      /* Added by Sarq on 8/21/98
       * this case is for new additions to the zone commands.
       * Specifically, it handles the following commands:

       *
       * modified by taerin 8/22/98
       * format: Z    
       * Xample: Z 0 1 0 0
       * legend: NOPORTAL 1    no portal in or out of this zone
       *         NOPKILL  2    no pkilling in this zone
       */
      switch (ZCMD.arg1) {
        case 1:
          test_log("Zone Command Z - 1 NOPORTAL initiated");
          zone_flags[zone].NOPORTAL = 1;            /* NO_PORTAL */
          break;
        case 2:
          test_log("Zone Command Z - 2 NOPKILL initiated");
          zone_flags[zone].NOPKILL = 1;           /* NO_PKILL */
          break;
        default:
          ZONE_ERROR("Bad use of zone command Z in reset table; cmd disabled");
          ZCMD.command = '*';
          break;
      } /* switch (ZCMD.arg1) */
      last_cmd = 1;
      test_log("Running ZONE command line with Z char"); /* sarq 8/21/98 */
      break;

---------------------------------------------------------------------------------

now implement the zone flags in the code:

in spells.c (portal spell) :
  after line : assert((level >= 0) && (level <= LVL_IMPL)); (roughly line 491)
  ADD:

  /* Sarq 8/21/98 - Zone Flag !PORTAL additon */
  /* ZONE_NOPORTAL(IN_ZONE(victim)) is the zone portal flag of the victim */
  /* ZONE_NOPORTAL(IN_ZONE(ch)) is the zone portal flag of the character */

  if (((ZONE_NOPORTAL(IN_ZONE(victim)) == 1) || (ZONE_NOPORTAL(IN_ZONE(ch)) == 1)) &&
      (GET_LEVEL(ch) < LVL_IMPL)) {
    /* Can't portal bitch!  Let's tell them that and end */
    send_to_char("Your target is protected!\n\r", ch);
    return;
  }

  /* taerin gets annoyed at grand central */
  if (IS_SET(rp->room_flags, ROOM_GODROOM)) {
    send_to_char("That room is private.\n\r", ch);            
    extract_obj(tmp_obj);
    return;
  }

add in roomflags too

in act.informative.c, void look_at_room:

  char zf_buf[128];
  *zf_buf = '\0';

    if (ZONE_NOPORTAL(IN_ZONE(ch)) == 1)
      strcat(zf_buf, " [ !PORTAL ]");
    if (ZONE_NOPKILL(IN_ZONE(ch)) == 1)
      strcat(zf_buf, " [ !PKILL ]");

    sprintf(buf2, "[%5d] %s [ %s] [ %s ]%s", world[ch->in_room].number,
           world[ch->in_room].name, buf, buf1, zf_buf);

---------------------------------------------------------------------------------

now implement the pkill flags in the code:

!pk_allowed = 0 will permit pkilling in designated zones
!pk_allowed = 1 will turn off pkilling globally

NOPKILL = 0 will allow pkill in the zone
NOPKILL = 1 will prevent pkill in zone

remove murder command
account for KILLER flag

ok to kill if:
1. !pk_allowed = 0, global pk protection is false; and
2. ZONE_NOPKILL(IN_ZONE(ch)) = 0, zone allows pkill

leave this check out until folks request it, being flagged is enough (with guards)
3. PLR_FLAGGED(victim, PLR_KILLER) = 1, victim is a KILLER
later on we can add that pkillers have NO protection at all in NOPKILL zones

therefore, block pkill if:
1. !pk_allowed = 1, global pk protection is true; or
2. ZONE_NOPKILL(IN_ZONE(ch)) = 1, zone doesn't allows pkill

so, replace all:
  if (!pk_allowed) {
with
  if ( (!pk_allowed) || (ZONE_NOPKILL(IN_ZONE(ch)) == 1) ) {

----

in act.offensive.c, ACMD(do_assist):    /* think about this do we want to assist also? */

    else if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) &&
              !IS_NPC(opponent))  /* prevent accidental pkill */

in act.offensive.c, ACMD(do_hit):

    if (!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) {

in act.offensive.c, ACMD(do_backstab):

  if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) && !IS_NPC(vict)) {

in act.offensive.c, ACMD(do_bash):

  if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) && !IS_NPC(vict)) {

in act.offensive.c, ACMD(do_rescue):

  if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) && !IS_NPC(vict)) {

in act.offensive.c, ACMD(do_kick):

  if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) && !IS_NPC(vict)) {

in act.wizard.c, do_status:     /* cosmetic fix */

      sprintf(buf, "%s[ SYS: %s disallows PKilling ]%s\r\n", CCRED(ch, C_NRM),
              GET_NAME(ch), CCNRM(ch, C_NRM));

      sprintf(buf, "%s[ SYS: %s allows PKilling ]%s\r\n", CCRED(ch, C_NRM), 
              GET_NAME(ch), CCRED(ch, C_NRM));

in fight.c, void set_fighting, check_killer regardless:

/*  if (!pk_allowed) */

in fight.c, void damage, check_killer regardless:

  /*  if (!pk_allowed) */ {

in fight.c, void fire_missile:

      if ((!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) && !IS_NPC(vict)) {

in spell_parser.c, ACMD(do_cast):

      if (!IS_NPC(tch) &&
          (!pk_allowed || (ZONE_NOPKILL(IN_ZONE(ch)) == 1)) &&
          SINFO.violent) {
        send_to_char("I don't think so ...\r\n", ch);

the following used to present a problem with area affect weapons:

in spell_parser.c:

extern int roomaffect_allowed;

in spell_parser.c, void mag_objectmagic, case ITEM_STAFF where it checks through each ch in room (because staves are inherently area affect):

        /* fixes the staff of ra problem, taerin 8/22/98 */
        if (!roomaffect_allowed && !IS_NPC(ch) && !IS_NPC(tch))
          continue;

in act.offensive.c, ACMD(do_hit):

replace:

      if (!IS_NPC(vict) && !IS_NPC(ch)) {
        if (subcmd != SCMD_MURDER) {
          send_to_char("Go to a PKILL zone and fight!\r\n", ch);
          return;
        } else {
          check_killer(ch, vict);
        }   
      }

with:

      if (!IS_NPC(vict) && !IS_NPC(ch)) {
        /* disabled SCMD_MURDER */
        send_to_char("Go to a PKILL zone and fight!\r\n", ch);
        return;
      }
