Enemy detected

สคริปต์เขียนโดย : Gubid
ลิงค์ต้นฉบับ : http://www.irpgth.com/community/School/2310-Script-Enemy-detected-...%99

รายละเอียด :
Script นี้เป็นสคริปต์ที่ดีอันนึงเลยครับ เป็นสคริปต์ที่ทำให้ศัตรูวิ่งเข้ามาหาเรา เมื่ออยู่ในระยะสายตาของศัตรู(กำหนดได้) เจ๋งดีครับ สำหรับคนที่ทำเกมส์
RPG และชอบทำศัตรูใน Map เพราะถ้าเรากำหนดให้มันเคลื่อนหาตัวเอกเนี่ย มันจะวิ่งมาตั้งแต่เราเริ่มเกมเลย แต่สคริปต์ตัวนี้ถ้าไม่เข้าไปในเขตการรับรู้
ของมัน มันก็เดินเฉยๆ

สกรีนช๊อต :
ไม่มีน่อ

วิธีการใช้งาน :
วิธีใช้ก็ง่ายๆ แค่กำหนด event มอนสเตอร์ในแมพ แล้วตั้งชื่อ Event นั้นว่า "enemy" แค่นั้นเอง ง่ายๆ
แต่ข้อเสียคือ การปรับค่าต่างๆ จะใช้กับศัตรูทั้งหมดนะครับ ไม่สามารปรับแต่งศัตรูแต่ละตัวได้น่ะครับ ใครมีฝีมือ ลองไป edit ดูนะ

ข้อตกลงการนำไปใช้งาน :
อย่างน้อยๆก็ใส่ชื่อ Gubid ลงในเครดิตด้วยล่ะ

โค๊ดสคริปต์

# 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 = true

#--------------------------------------------------------------------------

#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 = 5

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 = 9

#--------------------------------------------------------------------------

#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.

ดีมากๆ น่าจะรุ้จักสคริปนี้ก่อน
