I've been writing code for CircleMUD for about two years now, and I've got
a really good grasp on the game's code structure and mechanics.. but the
one thing I never tried until now was to create a specproc.
I made this item called "the cloak of the chameleon", and I wanted it to
make the wearer blend into their surroundings. I made an AFF_ flag in
structs.h and an appropriate addition to the affected_bits[] array. I do
not want this to be a settable flag via OLC (as to prevent builders from
creating copycats of the item), so I wrote a specproc. I tried two methods
of doing this.
First method:
-------------
obj_from_char(cloak);
equip_char(ch, cloak, ITEM_WEAR_ABOUT);
This did take the obj from their inven but never equipped it to them.
Second method:
--------------
perform_wear(ch, cloak, ITEM_WEAR_ABOUT);
This just crashes the server. I added "void perform_wear(blahblah);" at the
top of spec_procs.c.
Here's the whole specproc using the second method. I'm baffled as to what
could be causing these problems, but it's sure annoying :)
I'd like to get some insight from the CircleMUD community so I can actually
start to write better specprocs (I'll be sending some code to the devel
site as soon as I get snippets together :)
SPECIAL(chameleon_cloak)
{
char arg1[MAX_STRING_LENGTH];
struct obj_data *cloak;
skip_spaces(&argument);
one_argument(argument, arg1);
if(CMD_IS("wear"))
{
if(!(cloak = get_obj_in_list_vis(ch, arg1, NULL, ch-
>carrying)))
{
return(FALSE);
}
act("$n wears a strange looking cloak and blends into $s
surroundings.", FALSE, ch, NULL, NULL, TO_ROOM);
act("You wear the chameleon cloak and feel completely
hidden.", FALSE, ch, NULL, NULL, TO_CHAR);
SET_BIT(AFF_FLAGS(ch), AFF_CHAMELEON);
perform_wear(ch, cloak, ITEM_WEAR_ABOUT);
return(TRUE);
}
else if(CMD_IS("remove"))
{
if(!(cloak = get_obj_in_list_vis(ch, arg1, NULL, GET_EQ(ch,
ITEM_WEAR_ABOUT))))
{
return(FALSE);
}
perform_remove(ch, ITEM_WEAR_ABOUT);
act("$n is revealed as $e removes a strange looking
cloak.", TRUE, ch, NULL, NULL, TO_ROOM);
act("You feel completely revealed as you remove the
cloak.", FALSE, ch, NULL, NULL, TO_CHAR);
REMOVE_BIT(AFF_FLAGS(ch), AFF_CHAMELEON);
return(TRUE);
}
return(FALSE);
}
I hope it's not too ugly since it's my first specproc :)
