# CHARACTER SIZE SCRIPT
# Author Molegato
# Version 1.0
#------------------------------------------------------------------------------
# Allows you to make event, vehicle, player and followers character shrink or
# grow, as well as make maps have a default character size, actin like a zoom.
#------------------------------------------------------------------------------
# INSTRUCTIONS
# Every character will be of normal size if you don't do anything.
# For setting a character size for a map, add this tag to its notes:
#   <chara_size: size>
# Size = 1 means normal size, 2 is double, 0.5 is half, etc
# You can also change specific events, or even the player character,
# its followers, or vehicles to a specific size via event script call.
# for that, use:
#   $game_map.set_vehicle_size(index,size)
#       index=0 boat, 1 ship, 2 airship
#   $game_map.set_event_size(number,size)
#   $game_map.set_player_size(size)
#   $game_map.set_followers_size(size)
