Function Documentation

◆ absdir()

int absdir ( int d )

Computes an absolute direction.

Parameters

d	direction to convert.

Returns: number between 1 and 8, which represent the "absolute" direction of a number (it actually takes care of "overflow" in previous calculations of a direction).

◆ add_abilities()

void add_abilities	(	object *	op,
		const object *	change
	)

Used in artifact generation. The bonuses of the first object is modified by the bonuses of the second object.

For items that do not need identifying, use their identified face/animation immediately. This should make seas of generated creatures look more interesting.

Daniel Hawkins 2018-01-07

Add query flags to perform the same treatment for identified items or artifacts that come identified. Also make sure we have op->arch. Otherwise it segfaults when we don't.

2018-01-08

◆ animate_object()

void animate_object	(	object *	op,

	)

Updates the face-variable of an object. If the object is the head of a multi-object, all objects are animated. The object's state is not changed, but merely updated if needed (out of bounds of new animation, reached end of animation, ...). This function correctly handles FLAG_IS_TURNABLE too.

Parameters

op	is the object to animate.
dir	is the direction the object is facing. This is generally same as op->direction, but in some cases, op->facing is used instead - the caller has a better idea which one it really wants to be using, so let it pass along the right one. This parameter is ignored if the object has a head or is turnable.

Difficulty can now be set by the map creature. If the value stored in the map is zero, then use this routine. Maps should really have a difficulty set than using this function - human calculation is much better than this functions guesswork.

Permanently alters an object's stats/flags based on another object.

Note: flag is set to 1 if we are applying the object, -1 if we are removing the object.; It is the calling functions responsibilty to check to see if the object can be applied or not. The main purpose of calling this function is the messages that are displayed - fix_object should really always be called after this when removing an object - that is because it is impossible to know if some object is the only source of an attacktype or spell attunement, so this function will clear the bits, but the player may still have some other object that gives them that ability.

Changes experience to a player/monster. This does bounds checking to make sure we don't overflow the max exp.

The exp passed is typically not modified much by this function - it is assumed the caller has modified the exp as needed. skill_name is the skill that should get the exp added. flag is what to do if player doesn't have the skill. these last two values are only used for players.

Parameters

op	victim to alter.
exp	experience to gain (positive) or lose (negative).
skill_name	skill to change. Can be NULL.
flag	if experience gain, what to do if player doesn't have the skill if experience loss, whether to remove from all skills or only specified skill

		int	remove_others,
		int *	toremove
	)

Checks whether the altar has enough to sacrifice.

Function put in (0.92.1) so that identify altars won't grab money unnecessarily - we can see if there is sufficient money, see if something needs to be identified, and then remove money if needed.

0.93.4: Linked objects (ie, objects that are connected) can not be sacrificed. This fixes a bug of trying to put multiple altars/related objects on the same space that take the same sacrifice.

The function will now check for all items sitting on the altar, so that the player can put various matching but non merging items on the altar.

This function can potentially remove other items, if remove_others is set.

Parameters

	altar	item to which there is a sacrifice
	sacrifice	object that may be sacrifed
	remove_others	if 1, will remove enough items apart sacrifice to compensate for not having enough in sacrifice itself.
[out]	toremove	will contain the nrof of sacrifice to really remove to finish operating. Will be set if not NULL only if the function returns 1.

Returns: 1 if the sacrifice meets the needs of the altar, 0 else

This function should always be used for losing experience - the 'exp' value passed should be positive - this is the amount that should get subtract from the player.

Returns: -1 if it fails, otherwise the mode of the file is returned.

Note: Only the editor actually cares about the writablity of this - the rest of the code only cares that the file is readable. when the editor goes away, the call to stat should probably be replaced by an access instead (similar to the windows one, but that seems to be missing the prepend_dir processing

◆ describe_item()

StringBuffer* describe_item	(	const object *	op,
		const object *	owner,
		int	use_media_tags,
		StringBuffer *	buf
	)

Describes an item, in all its details.

If it is a monster, lots of information about its abilities will be returned.
If it is an item, lots of information about which abilities will be gained about its user will be returned.
If it is a player, it writes out the current abilities of the player, which is usually gained by the items applied.

It would be really handy to actually pass another object pointer on who is examining this object. Then, you could reveal certain information depending on what the examiner knows, eg, wouldn't need to use the SEE_INVISIBLE flag to know it is a dragon player examining food. Could have things like a dwarven axe, in which the full abilities are only known to dwarves, etc.

Add 'owner' who is the person examining this object. owner can be null if no one is being associated with this item (eg, debug dump or the like)

Parameters

op	object to describe. Must not be NULL.
owner	player examining the object.
use_media_tags	if non-zero, then media tags (colors and such) are inserted in the description. This enables the player to more easily see some things.
buf	buffer that will contain the description. Can be NULL.

Returns: buf, or new StringBuffer the caller must free if buf was NULL.

Note: This function is really much more complicated than it should be, because different objects have different meanings for the same field (eg, wands use 'food' for charges). This means these special cases need to be worked out.

Todo:: Check whether owner is really needed.
