Function Documentation

◆ add_abilities()

void add_abilities ( object op,
const object change 
)

Apply artifact properties to an object.

Parameters
opobject to apply changes to.
changechanges to apply, with fields handled as described in the artifacts file.

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.

◆ artifact_compute_chance_for_item()

void artifact_compute_chance_for_item ( const object op,
const artifact art,
int *  numerator,
int *  denominator

Compute the chance for a specified item to become the specified artifact. This does not take into account the 10% chance of an item being made an artifact.

Parameters
opitem to consider.
artartifact to compute the chance of.
numeratorchance in denominator for the artifact to be generated.
denominatordenominator, will never be 0.

void generate_artifact ( object op,

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.

Parameters
opobject to attempt to transform.
difficultylimit for artifact difficulty.

if the algorithm is changed, please update artifact_compute_chance_for_item above.
