static void fix_flesh_item	(	object *	item,

Objects of type FLESH are similar to type FOOD, except they inherit properties (name, food value, etc). based on the original owner (or 'donor' if you like). -b.t.

Parameters

item	FLESH item to fix based on the donor.
donor	what monster will give item.

◆ fix_generated_item()

void fix_generated_item	(	object *	op,
		object *	creator,
		int	difficulty,
		int	max_magic,
		int	flags
	)

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

◆ get_magic()

static int get_magic ( int diff )

static

get_magic(diff) will return a random number between 0 and 4. diff can be any value above 2. The higher the diff-variable, the higher is the chance of returning a low number. It is only used in fix_generated_treasure() to set bonuses on rings and amulets. Another scheme is used to calculate the magic of weapons and armours.

Parameters

difficulty	map difficulty.

Returns: generated level, 0 if invalid item.

void set_abs_magic	(	object *	op,

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. Daniel Hawkins 2021-01-19

Parameters

op	object we're modifying.
magic	magic modifier.

Sets a random magical bonus in the given object based upon the given difficulty, and the given max possible bonus.

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.

Based upon the specified difficulty and upon the difftomagic_list array, a random magical bonus is returned. This is a new way of calculating the chance for an item to have a specific magical bonus The array has two arguments, the difficulty of the level, and the magical bonus "wanted".

Initial value:

Resistances which can show up on rings and amulets. If you want to weight things so certain resistances show up more often than others, just add more entries in the table for the protections you want to show up.
