get_search_arr()

void get_search_arr

(

int *

search_arr

)

New function to make monster searching more efficient, and effective! This basically returns a randomized array (in the passed pointer) of the spaces to find monsters. In this way, it won't always look for monsters to the north first. However, the size of the array passed covers all the spaces, so within that size, all the spaces within the 3x3 area will be searched, just not in a predictable order.

Parameters

search_arr

array that will be initialized. Must contain at least SIZEOFFREE elements.

y	origin from which to search.
exclude	an object that will be ignored. Can be NULL.

Returns

direction toward the first/closest live object if it finds any, otherwise 0.

Note

Perhaps incorrectly, but I'm making the assumption that exclude is actually want is going to try and move there. We need this info because we have to know what movement the thing looking to move there is capable of.

object_can_merge()

int object_can_merge	(	object *	ob1,

Examines the 2 objects given to it, and returns true if they can be merged together, including inventory.

Note that this function appears a lot longer than the macro it replaces - this is mostly for clarity - a decent compiler should hopefully reduce this to the same efficiency.

Check nrof variable before calling object_can_merge()

Improvements made with merge: Better checking on potion, and also check weight

Parameters

ob1
ob2	objects to try to merge.

Returns

TRUE if they can be merged, FALSE else.

Checks if any objects has a move_type that matches objects that effect this object on this space. Call apply() to process these events.

Any speed-modification due to SLOW_MOVE() of other present objects will affect the speed_left of the object. 4-21-95 added code to check if appropriate skill was readied - this will permit faster movement by the player through this terrain. -b.t.

MSW 2001-07-08: Check all objects on space, not just those below object being inserted. object_insert_in_map may not put new objects on top.

Parameters

op	object that may trigger something.
originator	player, monster or other object that caused 'op' to be inserted into 'map'. May be NULL.

object_copy()

void object_copy	(	const object *	src_ob,

	)

Copy object first frees everything allocated by the second object, and then copies the contents of the first object into the second object, allocating what needs to be allocated. Basically, any data that is malloc'd needs to be re-malloc/copied. Otherwise, if the first object is freed, the pointers in the new object will point at garbage.

Parameters

src_ob	object that we copy.from
dest_ob	object that we copy to.

object_copy_owner()

void object_copy_owner	(	object *	op,
		object *	clone
	)

Set the owner to clone's current owner and set the skill and experience objects to clone's objects (typically those objects that where the owner's current skill and experience objects at the time when clone's owner was set - not the owner's current skill and experience objects).

Use this function if player created an object (e.g. fire bullet, swarm spell), and this object creates further objects whose kills should be accounted for the player's original skill, even if player has changed skills meanwhile.

Parameters

op	object to update.
clone	object from which to get the owner.

int object_find_free_spot	(	const object *	ob,

	)

object_find_free_spot(object, map, x, y, start, stop) will search for a spot at the given map and coordinates which will be able to contain the given object.

It returns a random choice among the alternatives found.

Parameters

ob	object to insert.
m
x
y	where to insert the object.
start
stop	first (inclusive) and last (exclusive) positions, in the freearr_ arrays, to search.

Returns

index into freearr_x and freearr_y, -1 if no spot available (dir 0 = x,y)

Note

this only checks to see if there is space for the head of the object - if it is a multispace object, this should be called for all pieces.

This function does correctly handle tiled maps, but does not inform the caller. However, object_insert_in_map will update as necessary, so the caller shouldn't need to do any special work.

Updated to take an object instead of archetype - this is necessary because arch_blocked (now ob_blocked) needs to know the movement type to know if the space in question will block the object. We can't use the archetype because that isn't correct if the monster has been customized, changed states, etc.

Frees everything allocated by an object, removes it from the list of used objects, and puts it on the list of free objects. The IS_FREED() flag is set in the object. The object must have been removed by object_remove() first for this function to succeed.

Inventory will be dropped on the ground if in a map, else freed too.

Parameters

ob	object to free. Will become invalid when function returns.

object_insert_in_map()

object* object_insert_in_map	(	object *	op,

This function inserts the object in the two-way linked list which represents what is on a map.

It will update player count if the op is a player.

Player ground window will be updated if needed.

Parameters

op	object to insert. Must be removed. Its coordinates must be valid for the map.
m	map to insert into. Must not be NULL.
originator	player, monster or other object that caused 'op' to be inserted into 'm'. May be NULL.
flag	bitmask about special things to do (or not do) when this function is called. See the object.h file for the INS_xxx values. Passing 0 for flag gives proper default values, so flag really only needs to be set if special handling is needed.

Returns

• new object if 'op' was merged with other object.
• NULL if 'op' was destroyed
• just 'op' otherwise

Todo:

this function is a mess, and should be cleaned.

object_matches_string()

int object_matches_string	(	object *	pl,
		object *	op,
		const char *	name
	)

This is a subset of the parse_id command. Basically, name can be a string seperated lists of things to match, with certain keywords. pl is the player (only needed to set count properly) op is the item we are trying to match. Calling function takes care of what action might need to be done and if it is valid (pickup, drop, etc.) Return NONZERO if we have a match. A higher value means a better match. 0 means no match.

Brief outline of the procedure: We take apart the name variable into the individual components. cases for 'all' and unpaid are pretty obvious. Next, we check for a count (either specified in name, or in the player object.) If count is 1, make a quick check on the name. IF count is >1, we need to make plural name. Return if match. Last, make a check on the full name.

Details on values output (highest is output):

match type return value

nothing 0 'all' 1 'unpaid' 2 'cursed' 2 'unlocked' 2 partial custom name 3 op->name with count >1 4 op->name with count <2 6 op->name_pl with count >1 6 inside base name 12 inside short name 12 begin of base name 14 custom name 15 base name 16 short name 18 full name 20 (note, count is extracted from begin of name parameter or from pl->contr->count, name has priority)

Parameters

pl	object we're searching an item for. Must not be NULL.
op	object we're considering. Must not be NULL.
name	string we're searching.

Returns

matching weight. The higher, the more the object matches.

Todo:

is the player->contr->count hack used?? Try to reduce buffers/calls to query_ functions.
