#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Allows you to change the zoom level on sprites depending on what they are on
# a per-map basis. This can be used to do things like making the character
# smaller on the main map, or creating a Lilliput village where the character
# is twice the size of the villagers.
#
#==============================================================================
# ▼ 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.
#
# All zoom values are percentages, so 100 is "no change".
#
# You can have multiple tags within single notetag, order is unimportant.
#
# -----------------------------------------------------------------------------
# Map Notetags - These notetags go in the map notebox in a map's properties.
# -----------------------------------------------------------------------------
# <zoom all=x ...>
# Set the zoom level for all sprites.
#
# <zoom player=x ...>
# Set the zoom level for the player *and* followers.
#
# <zoom follower=x ...>
# Set the zoom level for followers only.
#
# <zoom vehicle=x ...>
# Set the zoom level for any vehicles.
#
# <zoom npc=x ...>
# Set the zoom level for npcs, these are classed as any event that can move.
#
# <zoom event=x ...>
# Set the zoom level for any event that has a fixed position.
#
# -----------------------------------------------------------------------------
# Event Comments - These comments must be in the active page and are global.
# -----------------------------------------------------------------------------
# "ZOOM x"
# Set the zoom for this specific event (overrides map notetags).

# ▼ 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.
