Parameters:

	op	monster to check.
	enemy	enemy that can cause to wake up.
[out]	rv	vector pointing to enemy.

Returns:

1 if the monster should wake up, 0 otherwise.

void communicate	(	object *	op,
		const char *	txt
	)

This function looks for an object or creature that is listening to said text.

There is a rare event that the orig_map is used for - basically, if a player says the magic word that gets him teleported off the map, it can result in the new map putting the object count too high, which forces the swap out of some other map. In some cases, the map the player was just on now gets swapped out - thus, the object on that map are no longer in memory. So check to see if the players map changes, and if so, don't process any further. If it does change, most likely we don't care about the results of further conversation. Also, depending on the value of i, the conversation would continue on the new map, which probably isn't what is really wanted either.

Parameters:

op	who is saying something.
txt	what is said.

Computes a path from source to target.

Takes into account walls, other living things, and such. Only works if both items are on same map.

Parameters:

source	what wants to move.
target	target to go to.
default_dir	general direction from source to target.

Returns:

direction to go into. Will be default_dir if no path found.

Todo:

cache path, smart ajustment and such things to not compute all the time ; try directions randomly.

Tries to find an enmy for npc.

We pass the range vector since our caller will find the information useful. Currently, only move_monster calls this function. Fix function so that we always make calls to get_rangevector if we have a valid target - function as not doing so in many cases.

Parameters:

	npc	monster we're considering.
[out]	rv	vector that will contain how to reach the target. Must not be NULL.

Returns:

enemy npc wants to attack, or NULL if nont found.

object* find_nearest_living_creature

Returns the nearest living creature (monster or generator).

Modified to deal with tiled maps properly. Also fixed logic so that monsters in the lower directions were more likely to be skipped - instead of just skipping the 'start' number of direction, revisit them after looking at all the other spaces.

Note that being this may skip some number of spaces, it will not necessarily find the nearest living creature - it basically chooses one from within a 3 space radius, and since it skips the first few directions, it could very well choose something 3 spaces away even though something directly north is closer.

This function is map tile aware.

Parameters:

npc	monster to consider

Returns:

living creature, or NULL if none found.

This function was seen be continueing looping at one point (tmp->below became a recursive loop. It may be better to call monster_check_apply after we pick everything up, since that function may call others which affect stacking on this space.

static int monster_should_cast_spell	(	object *	monster,

	)		[static]

Checks if a monster should cast a spell.

Note that this function does not check to see if the monster can in fact cast the spell (sp dependencies and what not.) That is because this function is also sued to see if the monster should use spell items (rod/horn/wand/scroll).

Note that there are certainly other offensive spells that could be included, but I decided to leave out the spells that may kill more monsters than players (eg, disease).

This could be a lot smarter - if there are few monsters around, then disease might not be as bad. Likewise, if the monster is damaged, the right type of healing spell could be useful.

Parameters:

monster	monster trying to cast a spell.
spell_ob	spell considered.

Returns:

1 is monster should cast spell sp, 0 else.

Todo:

improve logic, take enemy into consideration.

static int monster_use_skill	(	object *	head,
		object *	part,
		object *	pl,
		int	dir
	)		[static]

monster_use_skill()-implemented 95-04-28 to allow monster skill use.

Note that monsters do not need the skills SK_MELEE_WEAPON and SK_MISSILE_WEAPON to make those respective attacks, if we required that we would drastically increase the memory requirements of CF!!

The skills we are treating here are all but those. -b.t.

At the moment this is only useful for throwing, perhaps for stealing. TODO: This should be more integrated in the game. -MT, 25.11.01

Will switch between at most 2 skills.

Parameters:

head	head of the monster.
part	part of the monster that may use a skill.
pl	target.
dir	direction to cast.

Returns:

1 if monster used a skill, 0 else.

Todo:

improve skill logic? Fix comments.
