Function Documentation

◆ convert_item()

static int convert_item	(	object *	item,
		object *	converter
	)

static

Transforms an item into another item.

Parameters

item	The object that triggered the converter - if it isn't of a type accepted by the converter, nothing will happen
converter	The object that is doing the conversion

Return values

-1	If something went wrong when attempting the conversion
0	If the item was not converted
1	If the item got converted

◆ converter_type_apply()

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

static

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.

Parameters

converter	The converter we applied
applier	The player applying the converter.
aflags	The apply flags (currently unused)

Returns: METHOD_OK

static

Move on this Converter object.

Parameters

trap	The Converter we're moving on
victim	The object moving over this one
originator	The object that caused the move_on event

Returns: METHOD_OK

◆ do_item_conversion()

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

static

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

Parameters

converter	The converter being used
item	The discovered source item object.
weight_rem	The 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.
status	The conversion status. 1 if successful, 0 if no conversion nor error, -1 if error. Caller cannot pass NULL here.

Returns: 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.
