# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2012.02.19 - Started Script and Finished.
# 
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script gives developers the ability to lock a map's parallax and cause
# it to not scroll by either vertically, horizontally, or both. Furthermore,
# this script also enables tile locking the map parallax, allowing the parallax
# to only move in conjunction with the player.
# 
#==============================================================================
# ▼ 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.
# -----------------------------------------------------------------------------
# <lock parallax x>
# This prevents the map's parallax from scrolling horizontally.
# 
# <lock parallax y>
# This prevents the map's parallax from scrolling vertically.
# 
# <full lock parallax>
# This prevents the map's parallax from scrolling at all.
# 
# <tile lock parallax>
# This causes the map's parallax to be locked to tiles and scrolls with them.
# 
#==============================================================================
# ▼ 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.
# 
#==============================================================================
# ▼ Editting anything past this point may potentially result in causing
# computer damage, incontinence, explosion of user's head, coma, death, and/or
# halitosis so edit at your own risk.

И в заметках карты пропиши потом <tile lock parallax>
Будешь к картам делать картинки оверлеем, названия файлов должны начинаться с [FIXED].
