#==============================================================================
# ▼ Updates
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# 2012.01.05 - Started Script and Finished.
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script allows you to make events that will chase the player or flee from
# the player when the player enters within range of the event or when the event
# sees 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.
#
# -----------------------------------------------------------------------------
# Move Script Call - Open up the script call in the event move menu and use:
# -----------------------------------------------------------------------------
# Add these variable changes to an event's move route to use them.
#
# @chase_range = x
# Event will chase the player after reaching x range.
#
# @flee_range = x
# Event will flee from player after reaching x range.
#
# @chase_speed = x
# Event will move at x speed when chasing.
#
# @flee_speed = x
# Event will move at x speed when fleeing.
#
# @sight_lock = x
# Event will chase/flee from player for x frames.
#
# @alert_balloon = x
# Event will show ballon ID x when chasing or fleeing.
#
# @alert_sound = x
# Event will play this sound upon sighting the player
#
# @see_player = true
# For events that require them to see the player first, use this script call
# inside the movement boxes. This does not follow line of sight rules, which
# means if there's a rock blocking you and the event, it will still see you.
#
#==============================================================================
# ▼ 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.
#

#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
# These settings adjust some general settings regarding chasing and fleeing
# events. Adjust them as you see fit.
#=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
# The number of frames before a balloon can show up again on the same
# event. This is to prevent a massive balloon spamming. 60 frames = 1 sec.
# By default, 120 frames is 2 seconds.
ALERT_TIMER = 120
# This is the default number of frames for how long the event will chase or
# flee from the player if used with @see_player = true. To change the amount
# individually for each event, use @sight_lock = x where x is a number.
# By default, 300 frames is 5 seconds.
SIGHT_LOCK = 300

在移动路径里加上这个 @see_player = true 的话，事件会先判定是否“看见”玩家（事件朝向和玩家朝向相向，x或y相同时） |
