You'll also have to make sure both objects are enchanted first, or their
affects will be on the index.
Maybe you can glean something useful from my do_add code.
--Palrich.
void do_add(CHAR_DATA *ch, char *argument)
{
int value;
OBJ_DATA *obj;
AFFECT_DATA pAf;
char loc[MAX_INPUT_LENGTH];
argument = one_argument(argument, loc);
if (!*loc || !(obj = get_obj_carry(ch, loc, ch)))
{
chprintf(ch, "Unable to find %s.\n\r", loc);
return;
}
argument = one_argument(argument, loc);
if (!*loc || !*argument || !is_number(argument))
{
send_to_char("Syntax: add [object] [location] [mod]\n\r", ch);
return;
}
if ((value = flag_value(apply_flags, loc)) == NO_FLAG)
{
send_to_char("Valid affects are:\n\r", ch);
show_help(ch, "apply");
return;
}
affect_enchant(obj);
pAf.location = value;
pAf.modifier = atoi(argument);
pAf.where = TO_OBJECT;
pAf.type = 0;
pAf.duration = -1;
pAf.bitvector = 0;
pAf.level = obj->level;
affect_join_obj(obj, &pAf);
send_to_char( "Affect added.\n\r", ch);
}
void affect_join_obj(OBJ_DATA *obj, AFFECT_DATA *paf)
{
AFFECT_DATA *paf_old;
AFFECT_DATA paf_new = *paf;
for (paf_old = obj->affected; paf_old != NULL;
paf_old = paf_old->next)
{
if (paf_old->where == paf_new.where
&& paf_old->location == paf_new.location)
{
paf_new.level = (paf_new.level += paf_old->level) / 2;
paf_new.duration += paf_old->duration;

affect_to_obj(obj, &paf_new);

affect_to_obj(obj, &paf_new);
