Function Documentation

◆ convert_item()

static int convert_item ( object item,
object converter 

Transforms an item into another item.

itemThe object that triggered the converter - if it isn't of a type accepted by the converter, nothing will happen
converterThe object that is doing the conversion
Return values
-1If something went wrong when attempting the conversion
0If the item was not converted
1If the item got converted

◆ converter_type_apply()

static method_ret converter_type_apply ( object converter,
object applier,
int  aflags 

Apply the converter object.

Looks for the desired type of the converter in top-level inventory and active containers, and performs the conversion until inventory is full or until conversion is exhausted.

converterThe converter we applied
applierThe player applying the converter.
aflagsThe apply flags (currently unused)

◆ converter_type_move_on()

static method_ret converter_type_move_on ( object trap,
object victim,
object originator 

Move on this Converter object.

trapThe Converter we're moving on
victimThe object moving over this one
originatorThe object that caused the move_on event

◆ do_item_conversion()

static object* do_item_conversion ( object converter,
object item,
int  weight_rem,
int *  status 

Do the actual item conversion. Determine the number of sources item to remove and the number of result items to produce.

converterThe converter being used
itemThe discovered source item object.
weight_remThe amount of weight we can add to the total. Used when doing direct-in-player-inventory conversions. Can be set to -1 if there is no weight limit, such as when using move_on.
statusThe conversion status. 1 if successful, 0 if no conversion nor error, -1 if error. Caller cannot pass NULL here.
A pointer to the produced object, which needs to be appropriately insert into map or inventory. Returns NULL if an error or no conversion happened.
