Subject: Proficiency

Here's the small backbone of my proficiency system.  It basicly implements
the ability to store profficiencies, but doesn't actually implement any.
They are used similarly to skills, but are learned (in my mud at least) by
special trainers in the land.  If you can't read the code and understand
it, I'd probably suggest not using it.  However, it QUITE simple and should
be no prob.  They do have a few examples of proficiencies coded in, but
very few.

STEP 1
------
Add these two files in your src directory:

    }
   else
     send_to_char("You aren't able to learn another proficiency at the
moment.\r\n", ch);

 return FALSE;
}

void check_sense_danger(struct char_data *ch)
{
   int door;

   for (door = 0; door < NUM_OF_DIRS; door++)
    if (EXIT(ch, door) && EXIT(ch, door)->to_room != NOWHERE &&
        IS_SET(ROOM_FLAGS(EXIT(ch, door)->to_room), ROOM_TRAP)) {

      if(number(1, 20) <= GET_WIS(ch)) {
       sprintf(buf, "\\c01You sense danger %s from here!\\c00\r\n",
dirs[door]);
       send_to_char(buf, ch);
     }
   }
}

const char *prof_name[] = {
"Swimming",
"Blind Fighting",
"Ambidexterity",
"Endurance",
"First Aid",
"Sense Danger"
};

#define GET_PROF_SLOTS(ch) ((ch)->player_specials->saved.prof_slots)

/* Here's the list of proficiencies you can have, change to fit your needs */
#define PROF_SWIMMING                                           0
#define PROF_BLIND_FIGHTING                                     1

#define PROF_SENSE_DANGER                                               5

STEP 2
------
Add these variables to structs.h:

You'll have to add a new one in player_specials_saved (this means pwipe
with binary) called

int proficiencies[MAX_PROFS];

and then add it again in char_player_data.

You'll need to define MAX_PROFS as well.  Just stick this line in structs.h
near some MAX_XXX defines

#define MAX_PROFS                       40  /* Change 40 to fit your needs */


STEP 3
------
Edit your makefile adding to your objfiles

prof.o

somewhere in the list.

Also, you must add this to the bottom of the file as well:

prof.o : prof.c prof.h structs.h
        $(CC) -c $(CFLAGS) prof.c
^^^^^^^^
this space must be a <TAB>

That should be all you need to get you started.  I hope this helps you out
with what you want.
