# ** Encounter Detection Chaser
#------------------------------------------------------------------------------
# SephirothSpawn
# Version 1.01
# 2007-08-29
# SDK : Version 2.0+, Part I, II
#------------------------------------------------------------------------------
# * Version History :
#
# Version 1 ---------------------------------------------------- (2007-08-16)
# Version 1.01 ------------------------------------------------ (2007-08-29)
# - Update : Moved move_toward_target method to MACL
#------------------------------------------------------------------------------
# * Requirements :
#
# Method & Class Library 2.11+
#------------------------------------------------------------------------------
# * Description :
#
# This script was designed to allow you to make quick events chase your
# player (or another event) with a simple comment line. You selete a target,
# a chase speed and a start and stop range (when the target gets x distance).
#------------------------------------------------------------------------------
# * Instructions :
#
# Place The Script Below the SDK and Above Main.
#
# Comment : ENCOUNTER DETECTION a b c d e f
#
# a : target (0 - player, event_id - event)
# b : speed (movement speed)
# c : start range (range when event starts chasing player)
# d : stop range (range when event stops chasing player) (should be > c)
# e : Animation id to display when in sight (optional)
# f : animation id to display when giving up (optional, but requires e)
#------------------------------------------------------------------------------
# * Syntax :
#
# You may change the chaser values, but when an event is refreshed, the
# instance @encdet_is_chaser is reset to false and if any comment lines
# are read, it will reset the instances as well.
#
# Instance List : encdet_is_chaser, encdet_is_chasing, encdet_chase_target
# encdet_chase_speed, encdet_chase_start_range,
# encdet_chase_stop_range, encdet_chase_start_aid,
# encdet_chase_stop_aid
#
# All instances of Game_Event

# * Special Thanks :
#
# Thanks to Khatharr for helping me debug the chaser bug.
