# ◦ Released on: 08/02/2009
# ◦ Version: 1.0
#--------------------------------------------------------------
# ◦ Compatibility:
#--------------------------------------------------------------
# □ This script will rewrite 6 method(s):
# Game_Map.start_scroll
# Game_Map.scroll_up
# Game_Map.scroll_down
# Game_Map.scroll_left
# Game_Map.scroll_right
# Game_Map.update_scroll
#
# □ This script will alias 1 method(s):
# Game_Map.setup_scroll
#
# □ This script would crash with other custom scripts that rewrite same method(s)
#
# □ This script may not work with maps that use loop.
#--------------------------------------------------------------
# ◦ Installation:
#--------------------------------------------------------------
# 1) This script should be placed JUST AFTER ▼ Materials.
#
# □ Like this:
# ▼ Materials
# * Smooth Scrolling
# ...
# ...
# ▼ Main Process
# Main
#
# 2) Setup this script in Setup Part below.
#
#--------------------------------------------------------------
# ◦ How to use:
#--------------------------------------------------------------
# □ Just place this script and try moving player in your game.
