脚本说明
移植自XP脚本 >Leyeshot2.1线形视野系统，做暗杀类游戏的葵花宝典！ By 流川枫
想测试效果的话，随便弄个范例地图，建个NPC，用事件脚本
$game_map.events[@event_id].le_seeing = true
$game_map.events[@event_id].le_show = true
就能看到效果了。

#==============================================================================
# [PS0]线形视野系统
# Linetype_Eyeshot
#------------------------------------------------------------------------------
# 非常强大、高效率的NPC视野系统
#==============================================================================
# [更新记录]
# - 2012.01.29 By 各种压力的猫君
# * 移植至RGSS3，遵循PS0协议
# - 2008.11.03 By LCF（流川枫 QQ:350773875）
# * 蓝本（LCF_Leyeshot XP 2.1）
#------------------------------------------------------------------------------
# [使用方法]
# - 将本脚本插入到MAIN以上
# - 当NPC看到主角时，会打开自身的独立开关D
#------------------------------------------------------------------------------
# [使用说明]
# - 在需要开启视野系统的NPC身上执行以下脚本至少一次即可
# 以下内容纯移植原脚本，下一版加入简化输入功能。
# - $game_map.events[@event_id].le_seeing = true/false
# 该值为true表示该NPC视野开启，否则未开启，默认为false。
# - $game_map.events[@event_id].le_clairv = true/false
# 该值为true表示该NPC视野不扫描视线障碍，否则扫描，默认为false。
# - $game_map.events[@event_id].le_show = true/false
# 该值为true表示显示该NPC的视线，否则不显示，默认为false。
# - $game_map.events[@event_id].le_side = true/false
# 该值为true表示该NPC可以看到侧面一格内的人，否则由斜率决定，默认为true。
# - $game_map.events[@event_id].le_circle = true/false
# 该值为true表示该NPC为环绕视野，否则不能看见自己的身后，默认为false。
# - $game_map.events[@event_id].le_deepness = 深度值
# 该值代表视野的能见度，默认为7。
# - $game_map.events[@event_id].le_slope = 斜率值
# 该值代表视野的斜率，默认为1.0。
# - $game_map.events[@event_id].le_color = 颜色值
# 该值代表视线显示的颜色，默认为0xf0。
