◆ animate_weapon()

int animate_weapon	(	object *	op,
		object *	caster,
		object *	spell,
		int	dir
	)

Generalization of staff_to_snake(). Makes a golem out of the caster's weapon. The golem is based on the archetype specified, modified by the caster's level and the attributes of the weapon. The weapon is inserted in the golem's inventory so that it falls to the ground when the golem dies. This code was very odd - code early on would only let players use the spell, yet the code was full of player checks. I've presumed that the code that only let players use it was correct, and removed all the other player checks. MSW 2003-01-06

Parameters

op	who is casting.
caster	what is casting.
spell	actual spell object.
dir	casting direction.

Return values

0	spell failure.
1	spell was successful.

◆ cast_create_missile()

int cast_create_missile	(	object *	op,
		object *	caster,
		object *	spell,
		int	dir,
		const char *	stringarg
	)

Create a missile (nonmagic - magic +4). Will either create bolts or arrows based on whether a crossbow or bow is equiped. If neither, it defaults to arrows. Sets the plus based on the casters level. It is also settable with the invoke command. If the caster attempts to create missiles with too great a plus, the default is used. The # of arrows created also goes up with level, so if a 30th level mage wants LOTS of arrows, and doesn't care what the plus is he could create nonnmagic arrows, or even -1, etc...

Parameters

op	who is casting.
caster	what is casting.
spell	actual spell object.
dir	casting direction.
stringarg	optional parameter specifying what kind of items to create.

Return values

0	no missile created.
missiles	were created.

◆ cast_create_town_portal()

int cast_create_town_portal	(	object *	op,
		object *	caster,

	)

This function cast the spell of town portal for op.

The spell operates in two passes. During the first one a place is marked as a destination for the portal. During the second one, 2 portals are created, one in the position the player cast it and one in the destination place. The portal are synchronized and 2 forces are inserted in the player to destruct the portal next time player creates a new portal pair. This spell has a side effect that it allows people to meet each other in a permanent, private, apartments by making a town portal from it to the town or another public place. So, check if the map is unique and if so return an error

◆ cast_invisible()

int cast_invisible	(	object *	op,

Makes the player or character invisible. Note the spells to 'stack', but perhaps in odd ways. the duration for all is cumulative. In terms of invis undead/normal invis, it is the last one cast that will determine if you are invisible to undead or normal monsters. For improved invis, if you cast it with a one of the others, you lose the improved part of it, and the above statement about undead/ normal applies.

Parameters

op	who is casting.
caster	what is casting.
spell_ob	actual spell object.

Return values

0	invisibility was already in action.
1	op is now invisible.
