Macro Definition Documentation

◆ DETOUR_AMOUNT

#define DETOUR_AMOUNT 2

This value basically determines how large a detour a monster will take from the direction path when looking for a path to the player.

The values are in the amount of direction the deviation is.

I believe this can safely go to 2, 3 is questionable, 4 will likely result in a monster paths backtracking.

Definition at line 611 of file player.cpp.

◆ MAX_SPACES

#define MAX_SPACES 50

This is used to prevent infinite loops.

Consider a case where the player is in a chamber (with gate closed), and monsters are outside. with DETOUR_AMOUNT==2, the function will turn each corner, trying to find a path into the chamber. This is a good thing, but since there is no real path, it will just keep circling the chamber for ever (this could be a nice effect for monsters, but not for the function to get stuck in. I think for the monsters, if max is reached and we return the first direction the creature could move would result in the circling behaviour. Unfortunately, this function is also used to determined if the creature should cast a spell, so returning a direction in that case is probably not a good thing.

Function Documentation

◆ action_makes_visible()

static int action_makes_visible ( object * op )

static

We call this when there is a possibility for our action disturbing our hiding place or invisibility spell.

Artefact invisibility is not effected by this. If we aren't invisible to begin with, we return 0.

This routine works for both players and monsters.

Parameters

op	object to check.

Returns: 1 if op isn't invisible anymore, 0 else.

◆ add_player()

player* add_player	(	socket_struct *	ns,
		int	flags
	)

Tries to add player on the connection passwd in ns.

Player object is created and put on the first map, rules/news/motd are sent.

Parameters

ns	connection.
flags	flag values are define in player.h: ADD_PLAYER_NEW - If set, go right to new character creation - used in case of new account code. We don't display motd and other bits in this case either. ADD_PLAYER_NO_MAP - Do not set up map information - used in character login method >2 where we do not use the same starting map.

Returns: player returns pointer to newly created player structure.

◆ apply_race_and_class()

int apply_race_and_class	(	object *	op,
		archetype *	race,
		archetype *	opclass,
		living *	stats
	)

This is somewhat like key_change_class() above, except we know the race to change to, but we still basically need to do the same work (apply bonuses, update archetype, etc.)

Parameters

op	Player object
race	race to use - caller should do sanity checking that this is a valid race.
opclass	class to use - like race, caller should do sanity checking.
stats	If set, use these stats for the character, do not apply new ones. Note: It is required that the caller only use valid stat values (generated by check_race_and_class() for example), as this function will not do checking on the stats.

Returns: 0 on success, non zero on failure (may be extended with unique error codes). It is the responsibility of the caller to notify the client of this failure.

◆ cast_dust()

Parameters

op	object throwing.
throw_ob	what to throw.
dir	direction to throw into.

◆ check_race_and_class()

int check_race_and_class	(	living *	stats,
		archetype *	race,
		archetype *	opclass
	)

This checks to see if the race and class are legal.

Legal in this contexts means that after apply the race/class stat modifiers, the race is still in legal range.

Parameters

stats	The statistics to modify - this data is modified, so the caller can use it on the next update.
race	The race to try and apply. It can be NULL, in which case no race will be applied.
opclass	The class to apply. It can be NULL, in which case no class will be applied.

Returns: 0 on success, 1 on failure. Note that no distinction is made on whether the failure is from race or class, as it is the final statistics which are important. For example, if race is -2 Str, and class is +2 Str, if the starting strength is 1, that is still legal (as final result is 1)

Similar to find_arrow(), but looks for (roughly) the best arrow to use against the target.

A full test is not performed, simply a basic test of resistances. The archer is making a quick guess at what he sees down the hall. Failing that it does it's best to pick the highest plus arrow.

Parameters

	op	who to search arrows for.
	target	what op is aiming at.
	type	arrow race to search for.
[out]	better	will contain the arrow's value if not NULL.

◆ find_key()

object* find_key	(	object *	pl,

This function merges both normal and locked door, since the logic for both is the same - just the specific key is different.

This function can be called recursively to search containers.

Parameters

pl	player.
container	inventory to searched for keys.
door	door we are trying to match against.

Returns: key to use, NULL if none found or usekeys mode doesn't let reach the key.

		int	dir
	)

The player is also actually going to try and move (not fire weapons).

This function is just part of a breakup from move_player(). It should keep the code cleaner. When this is called, the players direction has been updated (taking into account confusion).

Parameters

op	player moving.
dir	moving direction.

◆ op_on_battleground()

int op_on_battleground	(	object *	op,
		int *	x,
		int *	y,
		archetype **	trophy
	)

Check if the given object (usually a player) is standing on a battleground tile.

This is used to handle deaths and special attacks in arenas.

A battleground tile must have the following attributes set:

name "battleground"
type 58 (BATTLEGROUND)
is_floor 1 (must be the first tile beneath the player's feet)
no_pick 1
sp / hp > 0 (non-zero exit coordinates)

If the tile has 'slaying', 'maxhp', and 'maxsp' set, and the player has a matching marker, send the player to those coordinates instead.

If the tile has 'other_arch' set, then create that archetype as the trophy instead of the default ("finger").

Parameters

	op	Object to check (usually a player).
[out]	x
[out]	y	If not NULL and standing on a battleground tile, store exit coordinates.
[out]	trophy	If not NULL and standing on a battleground tile, store a pointer to the archetype that can be collected by the winner.

Returns: TRUE if op is on a battleground, FALSE if not.

◆ path_to_player()

int path_to_player	(	object *	mon,
		object *	pl,
		unsigned	mindiff
	)

Returns the direction to the player, if valid.

Returns 0 otherwise.

Modified to verify there is a path to the player. Does this by stepping towards player and if path is blocked then see if blockage is close enough to player that direction to player is changed (ie zig or zag). Continue zig zag until either reach player or path is blocked. Thus, will only return true if there is a free path to player. Though path may not be a straight line. Note that it will find player hiding along a corridor at right angles to the corridor with the monster.

Modified by MSW 2001-08-06 to handle tiled maps. Various notes:

With DETOUR_AMOUNT being 2, it should still go and find players hiding down corridors.
I think the old code was broken if the first direction the monster should move was blocked - the code would store the first direction without verifying that the player can actually move in that direction. The new code does not store anything in firstdir until we have verified that the monster can in fact move one space in that direction.
I'm not sure how good this code will be for moving multipart monsters, since only simple checks to blocked are being called, which could mean the monster is blocking itself.

Parameters

mon	source object.
pl	target.
mindiff	minimal distance mon and pl should have.

Returns: direction from mon to pl, 0 if can't get there.

◆ player_can_view()

int player_can_view	(	object *	pl,

Check the player los field for viewability of the object op.

This function works fine for monsters, but we dont worry if the object isnt the top one in a pile (say a coin under a table would return "viewable" by this routine). Another question, should we be concerned with the direction the player is looking in? Realistically, most of use cant see stuff behind our backs...on the other hand, does the "facing" direction imply the way your head, or body is facing? Its possible for them to differ. Sigh, this fctn could get a bit more complex. -b.t.

This function is now map tiling safe.

Parameters

pl	player that may see op.
op	what may be seen by pl.

Return values

-1	pl isn't a player
0	pl can't see op.
1	pl can see op.
