# 2012.01.03 - Added Feature: <all restrict: x>
# 2011.12.26 - Bug Fixed: Player Restricted Regions.
# 2011.12.15 - Started Script and Finished.
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Not everybody wants NPC's to travel all over the place. With this script, you
# can set NPC's to be unable to move pass tiles marked by a specified Region.
# Simply draw out the area you want to enclose NPC's in on and they'll be
# unable to move past it unless they have Through on. Likewise, there are
# regions that you can prevent the player from moving onto, too!
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# -----------------------------------------------------------------------------
# Map Notetags - These notetags go in the map notebox in a map's properties.
# -----------------------------------------------------------------------------
# <all restrict: x>
# <all restrict: x, x>
# Players and NPC's on the map will be unable to move past region x even if
# they have the "through" flag set. The only thing that can go past is if the
# player is using the debug through flag. Draw out the area you want to close
# the player and NPC's in with the regions and both will be unable to move onto
# any of those tiles marked by region x. If you want to have more regions
# restrict NPC's, insert multiples of this tag.
#
# <npc restrict: x>
# <npc restrict: x, x>
# NPC's on that map will be unable to move past regions x unless they have a
# "Through" flag on. Draw out the area you want to close NPC's in with the
# regions and the NPC's will be unable to move onto any of those tiles marked
# by region x. If you want to have more regions restrict NPC's, insert
# multiples of this tag.
#
# <player restrict: x>
# <player restrict: x, x>
# Players will not be able to move on tiles marked by region x unless the
# player has a "Through" flag on. Draw out the area you want to close the
# player in with the regions and the player will be unable to move past any of
# those tiles marked by region x. If you want to have more regions restrict the
# player, insert multiples of this tag.
#
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
