# 视野系统开关 $game_map.events[@event_id].le_seeing = true/false
# 功能：该值为true表示该NPC视野开启，否则未开启，默认为false。
#------------------------------------------------------------------------------
# 视野透视开关 $game_map.events[@event_id].le_clairv = true/false
# 功能：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。
#------------------------------------------------------------------------------
# 视线显示开关 $game_map.events[@event_id].le_show = true/false
# 功能：该值为true表示显示该NPC的视线，否则不显示，默认为false。
#------------------------------------------------------------------------------
# 侧面可视开关 $game_map.events[@event_id].le_side = true/false
# 功能：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。
#------------------------------------------------------------------------------
# 视野环绕开关 $game_map.events[@event_id].le_circle = true/false
# 功能：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。
#------------------------------------------------------------------------------
# 设置视野深度 $game_map.events[@event_id].le_deepness = 深度值
# 功能：该值代表视野的能见度，默认为7。
#------------------------------------------------------------------------------
# 设置视野斜率 $game_map.events[@event_id].le_slope = 斜率值
# 功能：该值代表视野的斜率，默认为1.0。
#------------------------------------------------------------------------------
# 设置显示颜色 $game_map.events[@event_id].le_color = 颜色值
# 功能：该值代表视线显示的颜色，默认为0xf0。
#==============================================================================
# 当NPC看到主角的时候，独立开关D会被打开,否则为关闭状态。
