Function Documentation

◆ 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.

◆ free_artifact()

static void free_artifact ( artifact * at )

static

Totally frees an artifact, its next items, and such.

Parameters

at	artifact to free. Pointer is free()d too, so becomes invalid.

Note: Objects at->item are malloc()ed by init_artifacts(), so can simply be free()d.

But artifact inventory is a 'real' object, that may be created for 'old' objects. So should be destroyed through object_free_drop_inventory(). Note that it isn't on the usual item list, so some tweaking is required.

Decides randomly which artifact the object should be turned into. Makes sure that the item can become that artifact (means magic, difficulty, and Allowed fields properly). Then calls give_artifact_abilities in order to actually create the artifact.
