#                          - party gold and item limits can now be set or use
#                          - the limit from a limit breaking script. (in theory)

#  2012-10-18 - Version 1.3 - Added banking SE
#  2012-10-18 - Version 1.2 - Added gold storage and more script calls
#  2012-10-17 - Version 1.1 - Added script calls to control stored items.
#  2012-10-16 - Version 1.0 - Released
#------------------------------------------------------------------------------#
#  An item storage script. Allows the player to store as many items as he/she
#  requires in bank-like storage that can be accessed from anywhere.
#
#  This script differs to my "Multiple Storage containers" script in that you
#  can have "banks" that store items and gold and can be accessed from anywhere.
#  It was designed to be used for one bank, but now has option to have more if
#  required.
#
#  My "Multiple Storage Containers" script stores only items within certain
#  events that can only be accessed by activating the particular event. This was
#  designed for location specific containers like chests, barrels, etc.
#
#  Here are some script calls that might be useful:
#------------------------------------------------------------------------------#
#
#  open_storage                        # Opens the item storage scene
#
#  store_add(type, id, amount)          # creates an item in storage
#  store_rem(type, id, amount)          # destroys an item in storage
#  store_count(type, id)                # returns amount of an item in storage
#
#  bank_add(amount)                    # adds amount of gold to bank
#  bank_rem(amount)                    # removes amount of gold from bank
#  bank_count                          # returns amount of gold in bank
#
#------------------------------------------------------------------------------#
#  EXPLAINATION:
#  type      this can be "weapon", "armor" or "item"
#  id        the ID of the item/armor/weapon
#  amount    the number of the item/armor/weapon/gold you want to remove
#
#  EXAMPLE OF USE:
#  store_add("weapon", 5, 20)
#  store_rem("item", 18, 99)
#  store_count("armor", 1)
#  bank_add(100)
#------------------------------------------------------------------------------#
#  More setup options further down.

  # BOX VARIABLE
  BOX_VAR = 0    # This is the variable ID to use to determine which box you are
                # adding/removing items from. Set the variable to a box number
                # right before any add/remove or opening storage script calls
                # to tell them which box they will affect.
                # Set to 0 if you only want 1 box storage in your game. You
                # then don't have to change a variable before each script call.

  # PARTY LIMITS
  # NOTE: These limits set to 0 will use the default limits. In theory this will
  # be compatible with a limit breaker script by leaving them at 0. Or you can
  # set the party limits below to whatever you like.

  MAX_GOLD = 0                    # Max gold your PARTY can carry.
                                  # This will overwrite the default limit.
                                  # 0 means do not use this.

  MAX_ITEMS = 0                  # Max items your PARTY can carry.
                                  # This will overwrite the default limit.
                                  # 0 means do not use this.
