# Cozziekuns Simple Sort Inventory
# Last Date Updated: 09/06/10

# the categories: All, Items, Weapons and Armours.
#
#===============================================================================
# Updates

# o 06/01/10 - Once again updated with Modern Algebra's recommendations.
# o 08/27/10 - Updated with Scrolling support. Thanks kawagiri for the idea, and
#              Modern Algebra for some help.

# Instructions
# -----------------------------------------------------------------------------
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ? Materials but above ? Main. Remember to save.
#
# Change the modules to your liking. The "hard" parts have instructions of their
# own.

#===============================================================================
# Extra Item Categories (Inspired by Modern Algebra)
# ------------------------------------------------------------------------------
# How should I go about explaining something like this? Well, basically, each
# item in the hash represents a certain category. For example, the first hash we
# see here is:
#
# 0 => [144, "All", false]
#
# The syntax of this is:
#
# Category ID => [Icon Number, Text, Prime]
#
# Probably the most important part, the category ID is the number you want to
# put into the notebox that the item contains. For example, if you wanted to
# make the item "World Map" into a key item, simply add the text:
#
# \item_category[4]
#
# into the notebox. Note that numbers 0, 1, 2, and 3 are special. They're prime
# categories. Sound special right? Not really, this just means you have to have
# them in the inventory for this script to work. I could've gotten rid of them,
# but that would've just given more work on your part (and mine), so bear with
# them, please. Icon Numbers and Text are pretty self explanatory.
#
# Last, but not least, is the "Prime" function (inspired by Kyraiki). Setting
# this to "true" means that anything in the prime category will not show up in
# the item, weapon or armour categories. You can set if you want it to show up
# in all.
