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.

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.

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.

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.

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

Parameters:

op	The spell effect.

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.

Here is the caller graph for this function:

static void 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:
