Wizards & Warriors in Inform 7 (v2)

Section 1 - Definitions

A wizard is a kind of person.
A warrior is a kind of person.

A weapon is a kind of thing.
A dagger is a kind of weapon.
A sword is a kind of weapon.
A staff is a kind of weapon.

Wielding is a thing based rulebook. The wielding rules have outcomes allow it (success), it is too heavy (failure), it is too magical (failure).
The wielder is a person that varies.

To consult the rulebook for (C - a person) wielding (W - a weapon):
	now the wielder is C;
	follow the wielding rules for W.

Wielding a sword: if the wielder is not a warrior, it is too heavy.
Wielding a staff: if the wielder is not a wizard, it is too magical.
Wielding a dagger: allow it.

To decide whether the rules allow (C - a person) to wield (W - weapon):
	consult the rulebook for C wielding W;
	if the rule failed, decide no;
	decide yes.

Wielding-ability relates a person (called C) to a weapon (called W) when the rules allow C to wield W. The verb to be able to wield (he can wield, they can wield, it can be wielded) implies the wielding-ability relation.

Section 2 - Example

Dungeon is a room.
Gandalf is a wizard in Dungeon.
Conan is a warrior in Dungeon.

The rusty dagger is a dagger in Dungeon.
The elvish sword is a sword in Dungeon.
The oaken staff is a staff in Dungeon.

Instead of giving a weapon (called W) to someone (called C):
	consult the rulebook for C wielding W;
	if the rule failed:
		let the outcome text be "[outcome of the rulebook]" in sentence case;
		say "[C] declines. '[outcome text].'";
	otherwise:
		now C carries W;
		say "[C] gladly accepts [the W]."

Instead of examining a person (called C) who is not the player:
	say "[C] can wield [the list of weapons that can be wielded by C]."

The can't take people's possessions rule is not listed in any rulebook.

Test me with "x gandalf / x conan / give sword to gandalf / give sword to conan / give staff to conan / give staff to gandalf / give dagger to gandalf / get dagger / give dagger to conan".
