# Yanfly Engine - IconView
# Last Date Updated: 2009.03.27
# Level: Easy
#
# Don't know how to use Photoshop's X and Y coordinates to count your icons or
# just too lazy to do it? Well, you can use this tool to make your life easier
# by loading up the icons on a static sheet and figuring out what those icons
# are indexed as. This script will mark 256 icons per page and allows you to
# scroll through those pages as lagless as possible. The icons are displayed
# in columns of 16 icons each, following exactly the way your IconSet is made
# (or should be made).
#
#===============================================================================
# Instructions
#===============================================================================
#
# Fire up your game in test mode. It'll display an extra option at the main menu
# which pulls up your icons and their icon index numbers for you. If the fourth
# option doesn't show up, then check IV_ENABLE to see if it's set to "true"
# instead of "false" since that triggers it, too.
#
# Note, when playing the game normally and not from RPG Maker VX, the IconView
# option won't show up at all.
#

# Updates:

# o 2009.03.30 - Started script.

#
# Compatibility
