Moved trading and pricing code to another folder, separate files. NPC: Added further inventory functionality. Trading: Added price data structure, which allows for setting prices for items. Also includes some default definitions.

-- Each NPCs has 2 favorite and 2 disliked items. These items are chosen at spawn
|
||||
-- time and will be re-chosen when the age changes (from child to adult, for example).
|
||||
-- The items are chosen from the npc.FAVORITE_ITEMS table, and depends on sex and age.
|
||||
-- A player, via right-click, or another NPC, can gift an item to a NPC. In the case
|
||||
-- of the player, the player will give one of the currently wielded item. Gifts can be
|
||||
-- given only once per some time period, the NPC will reject the given item if still
|
||||
-- the period isn't over.
|
||||
-- If the NPC is neutral on the item (meanining it's neither favorite or disliked), it
|
||||
-- is possible it will not accept it, and the relationship the giver has with the NPC
|
||||
-- will be unchanged.
|
||||
-- In the other hand, if the item given its a favorite, the relationship points the NPC
|
||||
-- has with giver will increase by a given amount, depending on favoriteness. Favorite 1
|
||||
-- will increase the relationship by 2 * npc.ITEM_GIFT_EFFECT, and favorite 2 only by
|

-- npc.ITEM_GIFT_EFFECT. Similarly, if the item given is a disliked item, the NPC will
