Introduction
As you know, trying to load a graphic image that isn't there can crash your game. Now you have a solution.
This system is an addition to the RPG::Cache system allowing you to run a test to see if a graphic image is part of your project or not. By running a test, it can return a true/false value before you attempt to load a file.

# INTRODUCTION AND INSTRUCTIONS:
#
# As you know, trying to load a graphic image that isn't there can crash your
# game. Now you have a solution.
#
# This system is an addition to the RPG::Cache system allowing you to run a
# test to see if a graphic image is part of your project or not. By running
# a test, it can return a true/false value before you attempt to load a file.
#
# There are two statements you can use:
#
# returned = RPG::Cache.test_1(type, filename)
# returned = RPG::Cache.test_2(type, filename)
#
# The first one, test_1, is designed to work with cache files that don't pass
# a hue value... like pictures, icons and the like. The second one, test_2,
# is designed to check for images that that have a hue value attached to them
# such as charactersets, battlers and so forth. You don't need to pass a hue
# value... it's just checking to see the file exists.
#
# EX: returned = RPG::Cache.test_1('tileset', '001-Grassland01')
#
# You must work with the names of the cache types as noted in the RPG::Cache
# system, but it should work with custom cache folders of your own design.

# This is a module that loads each of RPGXP's graphic formats, creates a
# Bitmap object, and retains it.
#==============================================================================
module RPG::Cache
#--------------------------------------------------------------------------
# * Test Cache File #1 (no hue option)
# type : cache type (autotile, icon, picture, etc.)
# filename : filename of the cached bitmap
#--------------------------------------------------------------------------
def self.test_1(type, filename)
failed = false
begin
bitmap = eval("self.#{type}(filename)")
rescue Errno::ENOENT
failed = true
end
return !failed
end
#--------------------------------------------------------------------------
# * Test Cache File #2 (existing hue option)
# type : cache type (character, battler, panorama, etc.)
# filename : filename of the cached bitmap
#--------------------------------------------------------------------------
def self.test_2(type, filename)
failed = false
begin
