# Crafting system
#
# Concept:
#
# Crafting assembles a new item by consuming ingredients.
# If you don't have the required ingredients, the item will be
# disabled in the crafting interface
#
# A recipe may be required to know how to craft an item
# One recipe can cover any number of items
# (e.g. a blacksmithing for beginners book could be the recipe for
# tier 1-2 weapons and armors in your game)
# If you don't have the recipe, the item won't even show up in the
# crafting interface.
#
# A tool may be required to craft an item.
# Tools are like ingredients but not consumed.
# (e.g. you need an alchemist's still to craft elixirs)
# If you don't have the tool, the item will be disabled in the
# crafting interface
#
# Ingredients to craft an item are specified by notetags
# on the item that can be crafted.
#
# <craft item:id>            - consume 1 item in crafting
# <craft item:id:quantity>   - consume (quantity) of item in crafting
# <craft weapon:id>          - consume 1 item in crafting
# <craft weapon:id:quantity> - consume (quantity) of item in crafting
# <craft armor:id>           - consume 1 item in crafting
# <craft armor:id:quantity>  - consume (quantity) of item in crafting
# <craft gold:quantity>      - price to craft this recipe
# <craft recipe:id>          - item id required to be able to see this
#                              craftable item in the interface
# <craft switch:id>          - game switch must be ON to see this recipe
# <craft tool:id>            - item id is required to craft this item,
#                              but is not consumed
#
# Additionally, there are tags to allow items to be broken down
# into ingredients.
#
# <craft break item:id>            - give 1 item in breakdown
# <craft break item:id:quantity>   - give (quantity) of item in breakdown
# <craft break weapon:id>          - give 1 item in breakdown
# <craft break weapon:id:quantity> - give (quantity) of item in breakdown
# <craft break armor:id>           - give 1 item in breakdown
# <craft break armor:id:quantity>  - give (quantity) of item in breakdown
# <craft break gold:quantity>      - price to perform this breakdown
# <craft break recipe:id>          - item id required to be able to see this
#                                    breakable item in the interface
# <craft break switch:id>          - game switch must be ON to see this recipe
# <craft break tool:id>            - item id is required to break this item.
#
# example: crafting a partisan requires 3 iron bars and a spear.
# And it can be broken down to give 2 iron bars back.
# <craft item:72:3>
# <craft weapon: 13>
# <craft break item:72:2>
#
# example: crafting spicy soup requires potato, meat and chilli
#          as well as a cauldron tool to cook it in.
# <craft item: 74>
# <craft item: 75>
# <craft item: 76>
# <craft tool: 80>
#
# Integration:
#
# By default, "Crafting" and "Breakdown" commands are added to the menu.
# To change this, or control when the commands are available, set the
# configuration variables in the section below.
#
# To call the crafting system from an event, use a script item:
# SceneManager.call(Scene_Crafting)
# Fiber.yield
#
# To call the breakdown system from an event, use a script item:
# SceneManager.call(Scene_Craft_Breakdown)
# Fiber.yield
#
#==============================================================================
