# 2012.01.05 - Compatibility Update: Equip Dynamic Stats
# 2012.01.03 - Started Script and Finished.

#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# The RPG Maker VX Ace shop scene is relatively basic. It provides adequate
# information, but not really enough to let the player know what they're
# actually buying or even selling. This script enables shops to show more than
# just the basic information displayed in RPG Maker VX Ace and even allow for
# custom commands to be inserted.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# -----------------------------------------------------------------------------
# Item Notetags - These notetags go in the item notebox in the database.
# -----------------------------------------------------------------------------
# <image: string>
# Uses a picture from Graphics\Pictures\ of your RPG Maker VX Ace Project's
# directory with the filename of "string" (without the extension) as the image
# picture shown in the Ace Shop Options.
#
# -----------------------------------------------------------------------------
# Weapon Notetags - These notetags go in the weapon notebox in the database.
# -----------------------------------------------------------------------------
# <image: string>
# Uses a picture from Graphics\Pictures\ of your RPG Maker VX Ace Project's
# directory with the filename of "string" (without the extension) as the image
# picture shown in the Ace Shop Options.
#
# -----------------------------------------------------------------------------
# Armour Notetags - These notetags go in the armour notebox in the database.
# -----------------------------------------------------------------------------
# <image: string>
# Uses a picture from Graphics\Pictures\ of your RPG Maker VX Ace Project's
# directory with the filename of "string" (without the extension) as the image
# picture shown in the Ace Shop Options.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
