  상점의 품목, 물품 수량, 상점생성은 이벤트 편집->스크립트에서 이루어집니다.  재고수량이 적어질수록 가격은 오르고, 역으로 수량이 늘수록 가격은 떨어집니다.  물론 재고가 소진되더라도 지정된 시간간격으로 재고가 하나씩 차게 됩니다.

# Economic Shop System - by Nick
# Version 2.134 (Hell yeah)
#----------------------------------------------------------------------------
# You may delete all comments except copyright.
# How to use:
# Step 1:
# -Create a shop using $eco.add_shop("name", "trade_type", "description")
# -"name", the store name, to identify shops, cant make 2 shops with same name
# -"trade_type", Standard it is both so you dont have to enter it, use "buy"
# -Or "sell" for buy/sell only shops.
# Step 2:
# -Add items using $eco.add_item(shop, item, type, amount, time_per_unit)
# -Shop can be either shop name or id.
# -Item is just the item id in the database.
# -Type is item(0), weapon(1) or armor(2)
# -Amount is the amount of items automatic in stock and it will restock to.
# -Time_per_unit is the time for 1 item to restock.
# Step 3:
# -Use call script; $scene = Eco_Scene_Shop.new(shopname/id)
# Note:
# -You can also use step 1 and 2 in Game_Economy, def initialize if you prefer.
# -Just replace $eco.shops with just @shops.
# Extra's:
# -If you are going to add items, it might be handier to use ID instead of name
# -For quick acces to ID use @id = $eco.retrieve_id(shopname) to put it in a string
# -Use module ES to adjust quick settings.
# -If you dont like the way i used to set prices, adjust def price in Data_Shopitems
# -And def calprice in Eco_Window_ShopNumber

**이 스크립트는 일반상점과 함께 사용가능합니다.  사용법은 이벤트 편집->스크립트에서:
상점생성: $eco.add_shop("name"(ID또는 상점이름), "trade_type"(buy/sell/both))
판매품목 추가: $eco.add_item(shop(ID또는 이름), item(아이템ID), type(item(0)/ weapon(1)/ armor(2)), amount(판매할 수량), time_per_unit(재고가 차는 시간간격))
상점호출: $scene = Eco_Scene_Shop.new(ID또는 이름)
