# Item Price Adjust - By JFace
# July 19, 2010
#
# This script adjusts the cost and sale price of items in game. This is
# particularly useful if using a Haggle type of event wherein the hero can
# pay less than asking price, and receive more money from sales. The cost
# and sale adjustments are customizable.
#
#
#
# Instructions
# -----------------------------------------------------------------------------
# To use this script, place this script anywhere below ? Materials
# but above ? Main. Save your game.
#
# There are four customizable features below. Read the comments.
# ==============================================================================
module JFace
module Discount
#===============================================================================
# Switch Initialization - Set up which switch ID you wish to use. This switch
# controls whether to use the standard item cost (when the switch is [OFF],
# or to use the adjusted item cost (when the switch is [ON].
#
CostSwitch = 3 # <-- This is a switch ID number
#===============================================================================
#===============================================================================
# Cost Adjust Variable - Set up which variable ID you wish to use. This variable
# controls the percent of adjustment to the standard item cost. For instance,
# when the variable value is set to 80, items will cost 80% of standard value.
# The switch associated to CostSwitch must be on for this value to take effect.
#
CostAdjust = 21 # <-- This is a variable ID number
#===============================================================================
#===============================================================================
# Sale Adjust Variable - Set up which variable ID you wish to use. This variable
# controls the percent of adjustment to the standard item sale. For instance,
# when the variable value is set to 50, items will sell for 50% of standard
# value. This value will always be in effect, regardless of CostSwitch.
#
SaleAdjust = 22 # <-- This is a variable ID number
#===============================================================================
#===============================================================================
# Local Switch Initialization - This should generally be kept false.
# false => the CostAdjust variable will not affect the sale price
# true => the CostAdjust variable will affect the sale price
#
DiscountSale = false # <== Must be true or false
#===============================================================================

# This concludes the customizable section of this script
