# ** Sprite_Character (Rewrite)
#------------------------------------------------------------------------------
#  By Siegfried (http://saleth.fr)
#------------------------------------------------------------------------------
#  This script rewrites Sprite_Character, the class used to display characters
#  on a map. It divides the update method to make it easier to alias.
