/*
* And now for Intelligent monster attacks (including spells).
*
* Original idea and code by "DRS" (David Reeves Sward).
* Major modifications by "BEN" (Ben Harrison).
*
* Give monsters more intelligent attack/spell selection based on
* observations of previous attacks on the player, and/or by allowing
* the monster to "cheat" and know the player status.
*
* Maintain an idea of the player status, and use that information
* to occasionally eliminate "ineffective" spell attacks.  We could
* also eliminate ineffective normal attacks, but there is no reason
* for the monster to do this, since he gains no benefit.
* Note that MINDLESS monsters are not allowed to use this code.
* And non-INTELLIGENT monsters only use it partially effectively.
*
* Actually learn what the player resists, and use that information
* to remove attacks or spells before using them.  This will require
* much less space, if I am not mistaken.  Thus, each monster gets a
* set of 32 bit flags, "smart", build from the various "SM_*" flags.
*
* This has the added advantage that attacks and spells are related.
* The "smart_learn" option means that the monster "learns" the flags
* that should be set, and "smart_cheat" means that he "knows" them.
* So "smart_cheat" means that the "smart" field is always up to date,
* while "smart_learn" means that the "smart" field is slowly learned.
* Both of them have the same effect on the "choose spell" routine.

/*
 * Creatures can cast spells, shoot missiles, and breathe.
 *
 * Returns "TRUE" if a spell (or whatever) was (successfully) cast.
 *
 * XXX XXX XXX This function could use some work, but remember to
 * keep it as optimized as possible, while retaining generic code.
 *
 * Verify the various "blind-ness" checks in the code.
 *
 * XXX XXX XXX Note that several effects should really not be "seen"
 * if the player is blind.  See also "effects.c" for other "mistakes".
 *
 * Perhaps monsters should breathe at locations *near* the player,
 * since this would allow them to inflict "partial" damage.
 *
 * Perhaps smart monsters should decline to use "bolt" spells if
 * there is a monster in the way, unless they wish to kill it.
 *
 * Note that, to allow the use of the "track_target" option at some
 * later time, certain non-optimal things are done in the code below,
 * including explicit checks against the "direct" variable, which is
 * currently always true by the time it is checked, but which should
 * really be set according to an explicit "projectable()" test, and
 * the use of generic "x,y" locations instead of the player location,
 * with those values being initialized with the player location.
 *
 * It will not be possible to "correctly" handle the case in which a
 * monster attempts to attack a location which is thought to contain
 * the player, but which in fact is nowhere near the player, since this
 * might induce all sorts of messages about the attack itself, and about
 * the effects of the attack, which the player might or might not be in
 * a position to observe.  Thus, for simplicity, it is probably best to
 * only allow "faulty" attacks by a monster if one of the important grids
 * (probably the initial or final grid) is in fact in view of the player.
 * It may be necessary to actually prevent spell attacks except when the
 * monster actually has line of sight to the player.  Note that a monster
 * could be left in a bizarre situation after the player ducked behind a
 * pillar and then teleported away, for example.
 *
 * Note that certain spell attacks do not use the "project()" function
 * but "simulate" it via the "direct" variable, which is always at least
 * as restrictive as the "project()" function.  This is necessary to
 * prevent "blindness" attacks and such from bending around walls, etc,
 * and to allow the use of the "track_target" option in the future.
 *
 * Note that this function attempts to optimize the use of spells for the
 * cases in which the monster has no spells, or has spells but cannot use
 * them, or has spells but they will have no "useful" effect.  Note that
 * this function has been an efficiency bottleneck in the past.
 *
 * Note the special "MFLAG_NICE" flag, which prevents a monster from using
 * any spell attacks until the player has had a single chance to move.

 * monster, and allowing fully energized monsters to move, attack, pass, etc.
 *
 * Note that monsters can never move in the monster array (except when the
 * "compact_monsters()" function is called by "dungeon()" or "save_player()").
 *
 * This function is responsible for at least half of the processor time
 * on a normal system with a "normal" amount of monsters and a player doing
 * normal things.
 *
 * When the player is resting, virtually 90% of the processor time is spent
 * in this function, and its children, "process_monster()" and "make_move()".
 *
 * Most of the rest of the time is spent in "update_view()" and "lite_spot()",
 * especially when the player is running.
 *
 * Note the special "MFLAG_BORN" flag, which allows us to ignore "fresh"
 * monsters while they are still being "born".  A monster is "fresh" only
 * during the turn in which it is created, and we use the "hack_m_idx" to
 * determine if the monster is yet to be processed during the current turn.
 *
 * Note the special "MFLAG_NICE" flag, which allows the player to get one
 * move before any "nasty" monsters get to use their spell attacks.
 *
 * Note that when the "knowledge" about the currently tracked monster
 * changes (flags, attacks, spells), we induce a redraw of the monster
 * recall window.
