11 * 2014 Deskull rearranged comment for Doxygen.\n
15 * This file includes code for eating food, drinking potions,
16 * reading scrolls, aiming wands, using staffs, zapping rods,
17 * and activating artifacts.
19 * In all cases, if the player becomes "aware" of the item's use
20 * by testing it, mark it as "aware" and reward some experience
21 * based on the object's level, always rounding up. If the player
22 * remains "unaware", mark that object "kind" as "tried".
24 * This code now correctly handles the unstacking of wands, staffs,
25 * and rods. Note the overly paranoid warning about potential pack
26 * overflow, which allows the player to use and drop a stacked item.
28 * In all "unstacking" scenarios, the "used" object is "carried" as if
29 * the player had just picked it up. In particular, this means that if
30 * the use of an item induces pack overflow, that item will be dropped.
32 * For simplicity, these routines induce a full "pack reorganization"
33 * which not only combines similar items, but also reorganizes various
34 * items to obey the current "sorting" method. This may require about
35 * 400 item comparisons, but only occasionally.
37 * There may be a BIG problem with any "effect" that can cause "changes"
38 * to the p_ptr->inventory_list. For example, a "scroll of recharging" can cause
39 * a wand/staff to "disappear", moving the p_ptr->inventory_list up. Luckily, the
40 * scrolls all appear BEFORE the staffs/wands, so this is not a problem.
41 * But, for example, a "staff of recharging" could cause MAJOR problems.
42 * In such a case, it will be best to either (1) "postpone" the effect
43 * until the end of the function, or (2) "change" the effect, say, into
44 * giving a staff "negative" charges, or "turning a staff into a stick".
45 * It seems as though a "rod of recharging" might in fact cause problems.
46 * The basic problem is that the act of recharging (and destroying) an
47 * item causes the inducer of that action to "move", causing "o_ptr" to
48 * no longer point at the correct item, with horrifying results.
50 * Note that food/potions/scrolls no longer use bit-flags for effects,
51 * but instead use the "sval" (which is also used to sort the objects).
