示例1: set_drop_count
void inventory_selector::set_drop_count(int it_pos, int count, const item &it)
{
// "dropping" when comparing means select for comparison, valid for bionics
if (it_pos == -1 && g->u.weapon.has_flag("NO_UNWIELD") && !compare) {
if (!warned_about_bionic) {
popup(_("You cannot drop your %s."), g->u.weapon.tname().c_str());
warned_about_bionic = true;
}
return;
}
// count 0 means toggle, if already selected for dropping, drop none
drop_map::iterator iit = dropping.find(it_pos);
if (count == 0 && iit != dropping.end()) {
dropping.erase(iit);
if (first_item == &it) {
first_item = second_item;
second_item = NULL;
} else if (second_item == &it) {
second_item = NULL;
}
} else {
// allow only -1 or anything > 0
