# Crafting System
# Version 1.9
# By Szyu
#
# About:
# Craft items, weapons and armors.
#
# Instructions:
# - Place below "? Materials" but above "? Main Process".
# - Call global Crafting List by "SceneManager.call(Scene_Crafting)" or
#       "SceneManager.call(Scene_Crafting, -1)".
#   For categorized Crafting Lists use "SceneManager.call(Scene_Crafting, x)"
#
# How to Use:
# - "<ingredients> content </ingredients>" marks the area for ingredients
# example:
#   <ingredients>
#   i: 3x 5   => 3 items of item_id 5
#   w: 2x 7   => 2 weapons of weapon_id 7
#   a: 1x 2   => 1 armor of armor_id 2
#   </ingredients>
#
# - "<recipe book>" marks the item as a recipe book, able to hold recipes
# - "<category: x>" marks a recipe book as category x. You can call seperate
#               category crafting lists by SceneManager.call(Scene_Crafting, x)
#
# - "<recipes> content </recipes>" marks the area for recipes if the
#                                  item is a crafting book
# example:
#   <recipes>
#   i: 5   => ability to craft the item with id 5
#   w: 7   => ability to craft the weapon with id 7
#   a: 2 - 20   => ability to craft armors from id 2 to id 20
#   </recipes>
#
# - "$data_items[book_id].add_recipe("i/w/a: id")" adds a new recipe to a book
# - "$data_items[book_id].add_recipe("i/w/a: id1 - id2")" adds a new recipe to a book
# - "$data_items[book_id].remove_recipe("i/w/a: id")" removes a recipe from a book
# - "$data_items[book_id].remove_recipe("i/w/a: id1 - id2")" removes a recipe from a book
