#   Z26 : Actor Stored Variables                                   Zetu Engine X
# ------------------------------------------------------------------------------
#   This scripts allows variables to be stored in local to each actor.  Each
#   variable type is, by default, 0.  You may change the data type of the
#   variable to anything, such as a string, but if you do, you CANNOT have that
#   variable inside LEVEL_FORMULAS!
# ==============================================================================

   # =========================================================================
   # Syntax: <Game_Actor>.vars.(stat).
   # -------------------------------------------------------------------------
   # <Game_Actor>   => $game_actors[ID] or $game_party.members[INDEX]
   # (stat)         => Any stat from STATS
   #==========================================================================
