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.

◆ move_bullet()

static object * move_bullet ( object * op )

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.

◆ 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
