◆ check_spell_knockback()

static void check_spell_knockback ( object * op )

static

Checks to see if a spell pushes objects as well as flies over and damages them (only used for cones for now) but moved here so it could be applied to bolts too.

Parameters

op	The spell object.

◆ execute_word_of_recall()

static void execute_word_of_recall ( object * op )

static

Handles the actual word of recalling.

Called when force in player inventory expires.

Parameters

op	The word of recall effect activating.

Definition at line 537 of file spell_effect.cpp.

◆ explosion()

static void explosion ( object * op )

static

Expands an explosion.

op is a piece of the explosion - this expans it in the different directions. At least that is what I think this does.

Parameters

op	piece of explosion expanding.

Definition at line 320 of file spell_effect.cpp.

◆ forklightning()

static void forklightning	(	object *	op,
		object *	tmp
	)

static

Causes op to fork.

Parameters

op	original bolt.
tmp	first piece of the fork.

Definition at line 848 of file spell_effect.cpp.

◆ init_type_spell_effect()

void init_type_spell_effect ( void )

Initializer for the SPELL_EFFECT object type.

Definition at line 54 of file spell_effect.cpp.

References register_move_on(), register_process(), SPELL_EFFECT, spell_effect_type_move_on(), and spell_effect_type_process().

◆ move_aura()

static void move_aura ( object * aura )

static

Process an aura.

An aura is a part of someone's inventory, which he carries with him, but which acts on the map immediately around him. Aura parameters: duration: duration counter. attacktype: aura's attacktype other_arch: archetype to drop where we attack

Parameters

aura	The spell effect.

◆ move_ball_spell()

static void move_ball_spell ( object * op )

static

This handles ball type spells that just sort of wander about.

Note that duration is handled by process_object() in time.c

Parameters

op	The spell effect.

◆ move_bolt()

static void move_bolt ( object * op )

static

Moves bolt 'op'.

Basically, it just advances a space, and checks for various things that may stop it.

Parameters

op	The bolt object moving.

Definition at line 156 of file spell_effect.cpp.

Referenced by spell_effect_type_process().

◆ move_bullet()

static object * move_bullet ( object * op )

static

Moves bullet 'op'.

Basically, we move 'op' one square, and if it hits something, call check_bullet. This function is only applicable to bullets, but not to all fired arches (eg, bolts).

Parameters

op	The bullet being moved.

Returns: The bullet at its new location, or NULL if it no longer exists.

Referenced by move_missile(), and spell_effect_type_process().

◆ move_cone()

static void move_cone ( object * op )

static

Causes cone object 'op' to move a space/hit creatures.

Parameters

op	cone object moving.

Referenced by spell_effect_type_process().

◆ move_missile()

static void move_missile ( object * op )

static

Move a missile object.

This is the same as move_bullet(), except that after moving, we update the projectile's direction (if it's still in existence) so that it homes in on things.

Parameters
