# ■ SephirothSpawn's Slanted bars in VX
#    25.4.2008
#------------------------------------------------------------------------------
#  Script by: Kylock (Based on SephirothSpawn's Original Slanted Bars)
#==============================================================================
#    Inspired by Syvkal (http://rmvxpuniverse.com) who ported Cogwheel Style
#  bars to VX, I realized how much I missed Seph's Slanted Bars.  So here they
#  are.  Just add this script and it'll automagically transform your HP and MP
#  bars.  Bar colors are easily customized in the following module.
#==============================================================================
#  Change Log
#  1.0 - Original Release.
#  1.1 - Added option to use default window skin colors.
#==============================================================================

module SLANT_BARS
  USE_WINDOWSKIN = false  # If set to true, the colors will be taken from the
                          #  current system skin and the following settings
                          #  will be ignored.
 
  DEFAULT_HP_BAR_COLOR = Color.new(150,0,0,255)  # Beginning color of HP bar
  DEFAULT_HP_END_COLOR = Color.new(255,192,0,255) # Ending color of HP bar
 
  DEFAULT_MP_BAR_COLOR = Color.new(0,0,150,255)  # Begenning color of MP bar
  DEFAULT_MP_END_COLOR = Color.new(0,150,200,255) # Ending color of MP bar
