이런식으로 변경됩니다.
체력이 부족하면 빨간색 중간은 노르스름한. 풀이면 초록색.이렇게 나오죠.. 자주 쓰이는 시스템.

# ** COGWHEEL Style Menu Bars
#------------------------------------------------------------------------------
# by Syvkal
# Version 1.9
# 04-26-08
#==============================================================================
#
# USAGE:
#
# This system is Plug 'N' Play
# It has been made so it will work as soon as you put it in the Script Editor
#
# However, it has also been made so you can easily make your own bars
# To draw a bar use:
# draw_custom_gauge
#
# Followed by:
# (value, max, x, y, width, height, color1, color2, use_windowskin)
#
# Value - is the thing your bar is made to draw
# Max - is the max value of what your bar is made to draw
# x, y - are the x and y values
# width, height - are the width and height values
# use_windowskin - if set to true it will take the colours from the windowskin
# it is set to false if not specified
# Color1, Color2 - these are the two colours to be used for the gradient
# Specify with Color.new(r,g,b,a) to set a colour
# If use_windowskin is set, simply put the number of the
# colour you want to use from the windowskin
