[djflan]

Does anyone know of or can write a small script to show enemy hp or hp bars during battle ? for rmvx.

RMVX Show HP Bars over enemies. There are a few constants you can play with to get different results and they are located at the top of Enemy_HPBar's class definition.  A word of notice. The battler sprites I have no idea what math they use to position there sprites but I can't seem to get it where I think it should be all the time. The the health bar might go wacky with certain sprites. I tested a few and the results were ok. But that's just a warning.

#==============================================================================
# ** HP_Bar

#  This sprite will show the user how much HP an enemy has.

  # * Constant Variables
  #--------------------------------------------------------------------------
  # The bar uses a gradient. Default is (red to green)/(left to right) 
  # respectively.
  HP_COLOR_LEFT = 
    Color.new(255, 0, 0) # The left color of the HP Bar. *Default : Red*
  HP_COLOR_RIGHT = 
    Color.new(0, 255, 0) # The right color of the HP Bar. *Default : Green*
  HP_BAR_LENGTH = 64     # The length of the bar. 1 pixel border is not 
                         # taken into account.
  HP_BAR_HEIGHT = 6      # The height ob the bar. 1 pixel border is not
                         # taken into account.

    # Move it up away from the sprite just a little.
