怎么使这两段脚本都能执行

上面那段是主角的坐标引发战斗，下面那段是队友的坐标引发战斗
[pre lang="ruby"]    distance = ($game_player.x - self.x).abs + ($game_player.y - self.y).abs
    enable   = (distance <= @sensor_range)
    key = [$game_map.map_id, self.id, XAS_BA::SENSOR_SELF_SWITCH]
    last_enable = $game_self_switches[key]
    last_enable = false if last_enable == nil
    if enable != last_enable
      $game_self_switches[key] = enable
      $game_map.need_refresh = true
    end
     if self.battler != nil
             for i in $duiwu_jsm
     duiyoum = $game_map.events.values.select{|ev| ev.event.name == i}
     for c in duiyoum
    distance = (c.x - self.x).abs + (c.y - self.y).abs
    enable   = (distance <= @sensor_range)
    key = [$game_map.map_id, self.id, XAS_BA::SENSOR_SELF_SWITCH]
