Trying to add a togglemurder function so players do not kill if they dont want to, for free pk fights or player events. Its been giving me a little problem but here is what I got.

the code.

void toggle_murder(CHAR_DATA *ch, char *argument)
{
   char *victim;

   set_char_color( AT_RED, ch );
   ch_printf( ch, "You are set to %s.\n\are.", xIS_SET( ch->act, PLR_MURDER ) ? "stun" : "murder" );
   if( !xIS_SET( ch->act, PLR_MURDER )
    2053->  xSET_BIT( ch->act, PLR_MURDER );
   else 
      xREMOVE_BIT( ch->act, PLR_MURDER );
   if( !IS_NPC( victim ) && xIS_SET( ch->act, PLR_MURDER ) && victim->hit < 1 )
  {
      victim->hit = 0;
      ch_printf( ch, "You spare your victim!" );
      act( AT_RED, "$n's life has been spared!", victim, NULL, NULL, TO_ROOM );
      act( AT_RED, "Your life has been spared, this time.", victim, NULL, NULL, TO_CHAR );
   }
   return;
}


the errors

 char *victim;

That's the problem. Needs to be:
 CHAR_DATA *victim;

Could you edit the first post and point out what those lines are? Also, remember to use the code tag.

[EDIT] Okay wait, this function seems odd. victim isn't even initialized. It's just declared. Unless I'm missing something.

You are missing a bracket. You have 2 LH brackets, and 1 RH bracket.

Putting aside other possible problems, like the fact that you are using "victim" without initialising it, the syntax error is because you are a bracket short. It should read:

if( !xIS_SET( ch->act, PLR_MURDER ) )

Just a typo.
void toggle_murder(CHAR_DATA *ch, char *argument)

There's no "do_" in there.

Like we said, victim isn't initialized. Basically this means that you declared space for it be defined, you use it (such as the !IS_NPC check) but it's never actually defined. It's still null.

isnt that what CHAR_DATA victim* is doing?

Here is the current code


void do_toggle_murder(CHAR_DATA *ch, char *argument)
{
   CHAR_DATA *victim;

   set_char_color( AT_RED, ch );
   ch_printf( ch, "You are set to %s.\n\r", xIS_SET( ch->act, PLR_MURDER ) ? "stun" : "murder" );
   if( !xIS_SET( ch->act, PLR_MURDER ))
      xSET_BIT( ch->act, PLR_MURDER );
   else
      xREMOVE_BIT( ch->act, PLR_MURDER );
   if( !IS_NPC( victim ) && xIS_SET( ch->act, PLR_MURDER ) && victim->hit < 1 )
  {
      victim->hit = 0;
      ch_printf( ch, "You spare your victim!" );
      act( AT_RED, "$n's life has been spared!", victim, NULL, NULL, TO_ROOM );
      act( AT_RED, "Your life has been spared, this time.", victim, NULL, NULL, TO_CHAR );
   }
   return;
}


and this is what my core file is saying when I check it.

#0 0x08148d2f in do_toggle_murder (ch=0x85c5fb0, argument=0xb54b4a4c "") at player.c:2056

maybe you guys can get an understaning of it better than I can :P

No, CHAR_DATA is declaring it, and that's it.

Well like I said earlier excuse my ignorance how would I define it, I tried looking for examples in other code and kinda drew blank, this is one of the first things I (kinda) wrote on my own. So sorry for the newbness.

Well my question is why is there a victim in the first place? Isn't that command only meant to toggle the setting?
