# Enemy Detection System
# by Gubid - 8/12/07
# v 1.2.2 Updated 10/2/07
#--------------------------------------------------------------------------
#Description:
#This system allows events that are named something including "ENEMY" then
#that event will be told to approach Game_Player, until Game_Player has gotten
#a specified distance away. At that time event will return to its original
#position if desired. If you happen to get close enough to the returning event
#it will begin to follow you again.
#
#Thanks to Near Fantasia for supplying the slightly modified path finding script.
#--------------------------------------------------------------------------
#if there are any questions as to the use of this script or
#modifications/additions/etc, please post it to the thread on CreationAyslum.net

#--------------------------------------------------------------------------
#Update_Detect - How to Stop Detection if desired
#--------------------------------------------------------------------------
#1. Within a event, add a SCRIPT (3rd page)
#2. type "update_detect(EVENT_ID, TRUE/FALSE)" -Note: it defaults to false
#--------------------------------------------------------------------------
#RETURN TO POSITION
#--------------------------------------------------------------------------
#Use this to determine if you would like the event to return to its original
#position or not.
#--------------------------------------------------------------------------
RETURN_TO_POSITION = false
#--------------------------------------------------------------------------
#CHASE_SPEED and ENABLE_SPEED_CHANGE
#--------------------------------------------------------------------------
#Use this to set the speed in which enemies will approach after spotting you
#and whether or not their speed will change.
#--------------------------------------------------------------------------
CHASE_SPEED = 4
ENABLE_SPEED_CHANGE = true
#--------------------------------------------------------------------------
#VIEW_RANGE
#--------------------------------------------------------------------------
#Use this to set the distance in which you must be in order to start the detection
#process, or escape to stop.
#--------------------------------------------------------------------------
VIEW_RANGE = 5
#--------------------------------------------------------------------------
#ESCAPE_RANGE
#--------------------------------------------------------------------------
#Use this to set the distance in which you must escape to stop the detection process
#--------------------------------------------------------------------------
ESCAPE_RANGE = 7
#--------------------------------------------------------------------------
#Other Notes
#--------------------------------------------------------------------------
#If the event has a custom move route, they will resume that route when finished
#chasing you, but if you dont set RETURN_TO_POSITION, then they will resume
#their custom route at the location they stopped chasing you.

Detailed Description:I want to add the functionality that when the player is behind the monster , the monster won't be able to start detection and chase the player. Even if the monster is in the range of detection. Therefore you can effectively sneak behind him to engage battle thus launching an initiative.
However, if detection has already started then even if the player is behind the monster, the monster will still be able to chase the player.
I think if this was with events I could do it easily with like, if player facing left and monster facing left then do not initialize monster alert/chase. But it's done with scripts and I'm not a scripter.
Also if possible I need this to be compatible with the caterpillar script. At the moment, the monster recognizes the caterpillar party members as an obstacle and therefore always are blocked by them.
Thank you for any help, and i will credit you in-game!
Screen shots:N/a I am sure you know what I mean. If you don't please state why.
Other Scripts I am using (in order):I dont think this will be much use because its only that script which need edits but here. Also I dont use SDK.
