# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2012.01.13 - Started Script and Finished.
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Sometimes, being able to buy items just isn't enough. With the common event
# shop, you can set anything to be sold as long as you can event it. Expanded
# upon the original Yanfly Engine ReDux version, the Ace version gives more
# options such as using custom switches to enable/disable common events from
# being bought or even appearing. And if that wasn't enough, advanced users can
# use eval strings for more conditional common events.
#
#==============================================================================
# ▼ 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.
#
# -----------------------------------------------------------------------------
# Common Event Notetags - These notetags go in a common event's comments.
# -----------------------------------------------------------------------------
# <cost: x>
# Sets the gold cost of the common event to x gold. If this notetag is not used
# the default gold cost will be whatever DEFAULT_COST is in the script module.
#
# <exit shop>
# When this event is bought, the player will automatically exit the shop before
# the common event will take place. If this tag is not used, the common event's
# contents will take place inside of the common event shop.
#
# <icon: x>
# Changes the icon used for the common event to x icon index. If this notetag
# is not used, the icon used for the common event will be whatever DEFAULT_ICON
# is in the script module.
#
# <image: string>
# Changes the image used for the common event to filename "string" found in
# the Graphics\Pictures\ folder. Requires Ace Shop Options to use. If this tag
# is not used, the image displayed will be the common event's expanded icon.
#
# <help description>
#  string
# </help description>
# Sets the text used for the help window in the shop scene. Multiple lines in
# the notebox will be strung together. Use | for a line break. Text codes may
# be used inside of the help description.
#
# <shop data>
#  string
# </shop data>
# Can be used if you have Yanfly Engine Ace - Ace Shop Options installed. Sets
# the string as the text shown inside the data window the shop. Use | for a
# line break. Text codes may be used inside of the shop data text.
#
# <shop variables: x>
# <shop variables: x, x>
# This sets the variable x displayed in the status window in the lower right
# corner of the screen. Insert multiples of this notetag to display more
# variables inside of the status window.
#
# <shop enable switch: x>
# <shop enable switch: x, x>
# This notetag will cause the common event item to require switch x to be ON
# before the common event can be bought. Insert multiples of these notetags to
# require more switches to be ON before the common event item can be gouth.
#
# <shop enable eval>
#  string
#  string
# </shop enable eval>
# Advanced users can enable and disable common events from being bought through
# this notetag. Replace string with lines of code to check for whether or not
# the common event can be sold. If multiple lines are used, they are considered
# to be a part of the same line.
#
# <shop show switch: x>
# <shop show switch: x, x>
# This notetag will cause the common event item to be hidden unless switch x is
# ON. Insert multiple of these notetags to require more switches to be ON
# before the common event item will be shown in the shop.
#
# <shop show eval>
#  string
#  string
# </shop show eval>
# Advanced users can show and hide common events from being listed in the buy
# list through this notetag. Replace string with lines of code to check for
# whether or not the common event will be shown. If multiple lines are used,
# they are considered to be a part of the same line.
#
# -----------------------------------------------------------------------------
# Script Calls - These commands are used with script calls.
# -----------------------------------------------------------------------------
# common_event_shop(x)
# This will call common event shop x. x will the shop ID used from the SHOPS
# hash in the script's module. Any items placed within the array assigned to
# the shop ID will be sold as common events.
#
#==============================================================================
# ▼ 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.
#
# This script is compatible with Yanfly Engine Ace - Ace Shop Options v1.00+.
# The position of this script does not matter relative to the other script.
