#   If you want to modify the bars, look @lines 42-72.You can see that
#     I simply took draw_actor_hp and turned it into draw_enemy_hp      
#     This means you can use any bars you desire so long as you define  
#     it correctly. =]

# CONFIG:
#
# I. Turning the Window On of Off during In-Game:
#
#    There are two kinds of switches you can use depending
#     upon your liking. I made it so that you either have a
#     game switch or a script switch that handles the enemy window flag.
#
#  If you want to use a script switch
#     -set USE_GSWITCH to false
#     -Use a call script, $game_system.enemy_window = true/false
#         True = Window Shows up, False = No Enemy Window
#
#  If you want to use a game switch
#     -Set USE_GSWITCH to true
#     -Decide what Game Switch ID you want to use
#         in ENEMY_WINDOW_SWITCH
#     -Use that game switch to check for showing the Enemy Hp Window
#        True = Window Shows up, False = No enemy window.
#
#
#  BY DEFAULT, USE_GSWITCH is false.
#     So you are using a Script Switch
#  
#  II.  ALWAYS_UPDATE
#         can either be set to true or false.
#         if true, the enemy window always update for every action
#             but the battle system will have more lag.
#         if false, the enemy window only updates at the end of each turn
#             and everytime the battle selection begins.
#         Setting it to false will lower compatibility but should still work
#        for most systems regardless.
#
# III. Spacing X and Y change
#    SPACING_X = Changing this number will change the X spacing of the windows
#    SPACING_Y = Changing this number will change the Y spacing of the windows
# IV. COLUMNS
#     COLUMNS = Draw enemy information by creating 4 columns.
# V. SHOW_STATES
#     if set to true, enemies state will be shown.
#======================================================================

                            # Setting it to true will use an in-game switch
                            #   using the switch ID below.
