◆ fix_generated_item()

void fix_generated_item	(	object *	op,

	)

fix_generated_item(): This is called after an item is generated, in order to set it up right. This produced magical bonuses, puts spells into scrolls/books/wands, makes it unidentified, hides the value, etc.

4/28/96 added creator object from which op may now inherit properties based on op->type. Right now, which stuff the creator passes on is object type dependant. I know this is a spagetti manuever, but is there a cleaner way to do this? b.t.

Parameters

op	object to fix.
creator	for who op was created. Can be NULL.
difficulty	difficulty level.
max_magic	maximum magic for the item.
flags	GT_ENVIRONMENT: if not set, calls fix_flesh_item(). GT_STARTEQUIP: Sets FLAG_STARTEQUIP on item if appropriate, or clears the item's value. GT_MINIMAL: Does minimal processing on the object - just enough to make it a working object - don't change magic, value, etc, but set it material type as appropriate, for objects that need spell objects, set those, etc

◆ generate_treasure()

object* generate_treasure	(	treasurelist *	t,
		int	difficulty
	)

Generate a treasure from a list generating a single item. This is similar to the old generate treasure function. However, it instead takes a treasurelist. It is really just a wrapper around create_treasure(). We create a dummy object that the treasure gets inserted into, and then return that treasure.

Warning: an error will be LOG()ed if more than one item is generated.

Parameters

t	treasure list to generate from.
difficulty	treasure difficulty.

Returns: generated treasure. Can be NULL if no suitable treasure was found.

Sets magical bonus in an object, and recalculates the effect on the armour variable, and the effect on speed of armour. This function doesn't work properly, should add use of archetypes to make it truly absolute.

Patched to utilize settings values for the speed/weight adjustments, rather than hardcoded ones. Neila Hawkins 2021-01-19

Parameters

op	object we're modifying.
magic	magic modifier.

Item will be cursed if magic is megative.

Parameters

◆ set_ring_bonus()

static void set_ring_bonus	(	object *	op,

static

Randomly adds one magical ability to the given object.

Modified for Partial Resistance in many ways: 1) Since rings can have multiple bonuses, if the same bonus is rolled again, increase it - the bonuses now stack with other bonuses previously rolled and ones the item might natively have. 2) Add code to deal with new PR method.

Changes the item's value.

Parameters

op	ring or amulet to change.
bonus	bonus to add to item.
