#  Elite Battle system
#    by Luka S.J.
# ----------------
#  BitmapWrapper Script
# ----------------
#  system is based off the original Essentials battle system, made by
#  Poccil & Maruno
#  No additional features added to AI, mechanics
#  or functionality of the battle system.
#  This update is purely cosmetic, and includes a B/W like dynamic scene with a
#  custom interface.
#
#  Enjoy the script, and make sure to give credit!
#-------------------------------------------------------------------------------
#  New animation methods for Pokemon sprites
#  * supports both animated, and static sprites
#  * does NOT support the usage of GIFs (officially)
#  * any one frame of sprite HAS to be of equal width and height
#  * all sprites need to be in 1*1 px resolution
#    or if you don't want to do that, you can change the value of
#    POKEMONSPRITESCALE to change the size of the bitmaps
#  * allows the use of custom looping points
#  Use dragonnite's(Lucy's) GIF to PNG converter to properly format your sprites
