Hey. I need a person who know's his/her way around scripts to make a very small tweak for me on Trace's Stealth System.
Here's the script, customized to how It will run in my game:
module Trace # <= don't touch this
#==============================================================================
# ? ??-VX ? Trace Stealth System ? version 2.2 ? P???. ???? ????
#------------------------------------------------------------------------------
# 1.0
# ? Initial release
# 1.1
# ? Alert no longer counts down while a message is displayed
# ? Revised the trace method, slimming it down and fixing the following bugs:
# ? Fixed a bug where tracers' vision would sometimes be blocked by itself
# ? Fixed a bug where tracers would see through Same As Characters events
# 2.0
# ? Added the sound stealth system
# ? Changed the way the trace range is handled
# ? Added ability to disable a tracer's senses
# 2.1
# ? Patched minors bugs
# 2.2
# ? Rewrote trace method using Bresenham's Line Algorithm
#==============================================================================
# ? Tracing With Style - please read everything!
#------------------------------------------------------------------------------
# Tracer (n): Anything that is searching for the player, e.g., a guard.
# Designate which events are a tracer by including "tracer" in its name.
# When a tracer event sees the player, the Alert Switch it turned ON.
# When the Alert Switch is turned on, a countdown begins. If the player
# remains out of site for 1800 frames, the Alert Switch is turned OFF.
ALERT_SWITCH = 1 # any game switch
ALERT_COUNTDOWN = 1800 # frames (60 frames is 1 second; 1800 frames is 30 sec)
#==============================================================================
# ? Change How Far Your Guards Can See
#------------------------------------------------------------------------------
# By default, tracers have an average range of vision: 5 tiles.
# A tracer's range should be odd: 3, 5, 7, 9, etc.
# An even value will be the next odd number, e.g., 4 will be a range of 5.
TRACE_RANGE_DEFAULT = 3 # any odd value
# You can change the range at any time by calling this line:
# ? $game_system.trace_range = n where n is the new sight range
# You may want to change the trace range when the lighting changes:
# ? For a dark room, or during the night, use 3 or 5.
# ? For a lit room, or during the day, use 5 or higher.
#==============================================================================
# ? Three Ways To Hide The Player From Sight
#------------------------------------------------------------------------------
# There are three methods that can be used to hide the player:
# ? Make the player transparent
# ? Make the player's opacity to HIDE_OPACITY or lower
# ? Change the Hide Switch to ON
HIDE_OPACITY = 100 # 0~255 (for realism, keep it low)
HIDE_SWITCH = 2 # any game switch
#==============================================================================
# ? 2.0 Feature ? Making a Ruckus: a guide to sound stealth ?
#------------------------------------------------------------------------------
# All noises have a loudness value which is it's range. For example, a
# noise with a loudness of 4 will be heard by all guards within 4 tiles.
# To make a noise, call the following line from within a Move Route command:
# ? tss_noise(n) where n is the range of the noise
# When a tracer hears a noise, its Caution Self Swith is set ON.
# To have the tracer move toward the source the sound, call the following
# line from within it's custom autonomous movement:
# ? tss_investigate
# Once the tracer reaches the source, its Caution Self Switch is set OFF.
CAUTION_SELF_SWITCH = "D" # "A", "B", "C", or "D"
# When the player sprints, he or she makes some noise!
# You can change how much noise is made at any time by calling this line:
# ? $game_player.sprint_noise = n where n is the range of the noise
DEFAULT_SPRINT_NOISE = 3 # any value (set this to 0 to disable)
# Here are some example of noises and their estimated range:
# ? Creaking Floor............ 1~2
# ? Carefully Closing a Door.. 2~3
# ? Sneezing or Coughing...... 4~5
# ? Bumping Into Something.... 4~5
# ? Tripping Over Furniture... 6~7
# ? Breaking Glass............ 8~9
# Sprinting:
# ? Thief Sprinting........... 2~3
# ? Civilian Sprinting........ 4~6
# ? Soldier Sprinting......... 7~9
# Dialogue:
# ? Whispering................ 2~3
# ? Talking................... 4~6
# ? Shouting.................. 7~9
#==============================================================================
# ? 2.0 Feature ? Two Ways To Disable a Tracer's Senses
#------------------------------------------------------------------------------
# There are two methods that can be used to disable a tracer's "senses":
# ? Erase the tracer event
# ? Change it's Disabling Self Switch to ON
# Prof tip: "D" is for many things- dead, disabled.... When you knock out a
# guard, erase or turn it's "D" self switch ON so he can't see or hear you!
ALLOW_SELF_SWITCH_DISABLING = true # true~false
DISABLING_SELF_SWITCH = "B" # "A", "B", "C", or "D"
#==============================================================================
# ? Special Effects
#------------------------------------------------------------------------------
# When a guard sees you, an ! appears above all heads and an ME plays.
SHOW_ALERT = false # Do you want the ! to display? true~false
PLAY_ALERT = false # Do you want an ME to play? true~false
ALERT_ME = "Audio/ME/Shock" # Which ME do you want to play? any ME
ALERT_VOLUME = 100 # At what volume? 0~100
ALERT_PITCH = 100 # At what pitch? 50~150
# When the guards call off the search, a ? appears above all heads.
SHOW_QUIT = true # Do you want the ? to display? true~false
# 2.0 Feature ? When a guards hears a noise, a ? appears above it's head
# and an ME plays.
SHOW_CAUTION = true # Do you want the ? to display? true~false
PLAY_CAUTION = false # Do you want an ME to play? true~false
CAUTION_ME = "Audio/ME/Mystery" # Which ME do you want to play? any ME
CAUTION_VOLUME = 100 # At what volume? 0~100
CAUTION_PITCH = 100 # At what pitch? 50~150
#==============================================================================
# ? 2.0 Feature ? Something For Fun
#------------------------------------------------------------------------------
# You can call huh? or hey! through an event script to display '?' or '!'
# above all active tracer heads!
#==============================================================================
# ? DO NOT TOUCH ANYTHING BELOW THIS POINT - this is for your own safety!

So, when switch 1 is activated, the Guard will automatically run at my character. I would like him to just stand still instead, but I'm not sure how to do it. Anybody willing to change whatever needs to be changed to make the Guard stand still when he sees me instead of runs to me?
