# Yanfly Engine Zealous - Variable Backdrops
# Last Date Updated: 2010.02.07
# Level: Normal
#
# One of the greatest things to come out of RPG Maker 2003 that didn't appear in
# any of its successors was moving backdrops during battle. There was a front
# layer and then a back layer and it broke the monotony of a static background.
# This script lets you recreate all of that with ease and control it with ease.
# Just change a variable value inside the event editor and you'll receive the
# listed backdrop found in the hash within this script.
#
# Also now, when a backdrop variable changes during battle, its graphic will
# update and show the newer backdrop. This allows for interesting battles where
# scenes are constantly shifting and whatnot.
#
#===============================================================================
# Updates
# -----------------------------------------------------------------------------
# o 2010.02.07 - Started Script and Finished.
#===============================================================================
# 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.
#
# - Download Backdrops from Pockethouse.com and unzip it to your Graphics folder
# into your "Parallaxes" folder.
# - Bind BATTLE_SHADOW_SWITCH to a switch. By default, it's 60.
# - Bind the following to variables
# VARIABLE_MIST_OPACITY - Default 56 - Adjusts the mist opacity.
# VARIABLE_MIST_IMAGE - Default 57 - Sets the fog that covers enemies.
# VARIABLE_FRONT_IMAGE - Default 58 - Front background layer.
# VARIABLE_MIDDLE_IMAGE - Default 59 - Middle background layer.
# VARIABLE_BACK_IMAGE - Default 60 - Back background layer.
#
# Change the variables in your event editor to reflect the backdrop you want to
# see in battle. Toggle the BATTLE_SHADOW_SWITCH switch if you want to hide/show
# the floor shadow inbattle. Adjust the hashes down below if you want to add
# more backdrops to your game.
#
#===============================================================================
# Compatibility
# -----------------------------------------------------------------------------
# - Works With: Nearly everything that doesn't affect backdrops.
# -----------------------------------------------------------------------------
# Note: This script may not work with former Yanfly Engine ReDux scripts.
# Use Yanfly Engine Zealous scripts to work with this if available.
