# Yanfly Engine RD - Variable Controlled Discounts
# Last Date Updated: 2009.06.03
# Level: Normal
#
# As much as I love price changer scripts and everything, it becomes a tedious
# job to manually adjust the price of each individual item (and calculating the
# new prices) for just one shop and then having to do it again for another. This
# script adjusts the prices of everything sold in the shop by a percentage and
# is controlled by a variable so you don't have to script event it each time.
#
#===============================================================================
# Updates:
# ----------------------------------------------------------------------------
# o 2009.06.03 - Increased compatibility with KGC Limit Break.
# o 2009.05.09 - Started script and finished.
#===============================================================================
# Instructions
#===============================================================================
#
# By default, the variables are as follows:
#
# PERCENT_BUY = Variable 67 = Affects the percentage that will affect the price
# the player will buy the item for.
# PERCENT_SELL = Variable 68 = Affects the percentage that will affect the price
# the player will sell the item for.
#
# Before processing a shop event, input the two variables into the event list
# and adjust the percentage rate you wish for the player to buy/sell items at.
# For normal shops, the rate should be 100 for buying and 50 for selling.
#
#===============================================================================
#
# Compatibility
# - Works With: KGC Limit Break
# - Alias: Scene_Shop: update_buy_selection, update_sell_selection
# - Overwrites: Scene_Shop: decide_number_input
#
