◆ fix_generated_item()

void fix_generated_item ( object op,

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
opobject to fix.
creatorfor who op was created. Can be NULL.
difficultydifficulty level.
max_magicmaximum 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

Returns

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. Neila Hawkins 2021-01-19

Parameters
opobject we're modifying.

Item will be cursed if magic is megative.

◆ set_ring_bonus()

static void set_ring_bonus ( object op,
int  bonus 
)
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
opring or amulet to change.
bonusbonus to add to item.
