# Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script based on Hanzo Kimura's idea. This will automatically load map's
# overlay by map ID, and a map can have more than one image per layer, so you
# don't have to create two or more map just for day/night or when an event occur.
#
#==============================================================================
# Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Create a folder in Graphics and name it Overlay.
# Put all of your overlay into Graphics/Overlay.
# Your overlay file will have the name: "Filename Prefix" + Map-ID + "-" + Number
# which "Filename Prefix" is the one you will config below
# Map-ID is your map's ID
# Number is 1, 2, 3, ... using for Overlay Variables.
#
# Example: Graphics/Overlay/ground2-1.png
# Which means this will be ground layer, for map 2, variable = 1
#
# Light/Shadow must be .jpg
# Parallax/Ground must be .png
#
