Description of affected_type structure:
|
||
|
|
|
||
|
|
struct affected_type
|
||
|
|
{
|
||
|
|
byte type; /* The type of spell that caused this */
|
||
|
|
byte duration; /* For how long its effects will last */
|
||
|
|
byte modifier; /* This is added to apropriate ability */
|
||
|
|
byte location; /* Tells which ability to change(APPLY_XXX)*/
|
||
|
|
long bitvector; /* Tells which bits to set (AFF_XXX) */
|
||
|
|
|
||
|
|
struct affected_type *next;
|
||
|
|
};
|
||
|
|
|
||
|
|
The type is set to the constants defined in spells.h. These are any of
|
||
|
|
SPELL_XXX, ei. SPELL_ARMOR.
|
||
|
|
|
||
|
|
Duration will be decreased at each time update.
|
||
|
|
|
||
|
|
Location is determined by the APPLY_XXX, ei. APPLY_STR to change strength.
|
||
|
|
|
||
|
|
Modifier will be added to the apropriate APPLY_XXX
|
||
|
|
|
||
|
|
Bitvector will set bits in the char_data->char_special_data.affected_by
|
||
|
|
|
||
|

Description of handler.c routines:
|
||
|
|
|
||
|
|
|
||
|
|
void affect_location_apply ( struct char_data *ch,
|
||
|
|
struct affected_type *af, int type);
|
||
|
|
|
||
|
|
/* This procedure will (depending on type) Apply or Remove a characters */
|
||
|
|
/* special bonus to abilities, which have been gained by spells */
|
||
|
|
|
||
|
|
When Type is 1, Modifier will be added to an ability, and Bitvector will
|
||
|
|
set bits in the "char_data->char_special_data.affected_by" bitvector. When
|
||
|
|
Type == 0, Modifier is subtracted, and bits are removed.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
void affect_to_char( struct char_data *ch, struct affected_type *af )
|
||
|
|
|
||
|
|
This procedure allocates new memory for an affected_type structure, and
|
||
|
|
inserts a copy of "*af" in the char_data->affected linked list. After
|
||
|
|
insertion, the "affect_location_apply" is called, with type == 1.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
void affect_remove( struct char_data *ch, struct affected_type *af )
|
||
|
|
|
||
|
|
This procedure is the reverse of affect_to_char. Upon calling "af" MUST
|
||
|
|
point to the structure(element) in the linked list that is to be removed.
|
||
|
|
If not, the program will do an "exit()". Memory used is released, and
|
||
|
|
"affect_location_apply" is called, with type == 0.
|
||
|
|
BEWARE! Some spells may have several structures, since they must change
|
||
|
|
more than one attribute! Calling affect_from_char does not mean that you
|
||
|
|
have removed every occurence of a certain spell. But you can be sure that
|
||
|
|
bits are masked out! Use affect_from_char below.
|
||
|
|
---------------------------------
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
void affect_from_char( struct char_data *ch, byte skill )
|
||
|
|
|
||
|
|
This fixes the warning above, by calling affect_remove with every
|
||
|
|
structure that has same spelltype set as skill.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
bool affected_by_spell( struct char_data *ch, byte skill )
|
||
|
|
|
||
|
|
This procedure will check if a character is affected by a spell (the
|
||
|
|
SPELL_XXX constants are used). Returns FALSE if not, otherwise TRUE.
