这段脚本在一个窗口中显示4个角色的状态，初始角色是4个的时候执行正常，初始角色小于4个，就出问题了。请问如何修改，是判断初始角色是否存在还是有其他办法。
下面是窗口的刷新判断
[pre lang="ruby" line="1"]  #----------------------------------------------------------------------------
  # * 刷新画面
  #----------------------------------------------------------------------------
  def update
    super
    refresh if $refresh
    $refresh = false
    if $game_player.screen_x >= 0 and $game_player.screen_x <= self.width and
       $game_player.screen_y >= 0 and $game_player.screen_y <= self.height
      self.contents_opacity = 60
    else self.contents_opacity = 255
    end
  end
[/pre]
以及刷新处理
[pre lang="ruby" line="1"]class Game_Actor < Game_Battler
  #----------------------------------------------------------------------------
  # * 重命名方法
  #----------------------------------------------------------------------------
  alias ms_refresh refresh
  alias ms_tp tp=

    ms_tp(tp)
    $refresh = true
  end
  #----------------------------------------------------------------------------
  # * 附加状态
  #----------------------------------------------------------------------------
  def add_state(state_id)
    ms_add_state(state_id)
    $refresh = true
  end
end

class Game_Party
  #----------------------------------------------------------------------------
  # * 重命名方法
  #----------------------------------------------------------------------------
  alias ms_swap_order swap_order
  #----------------------------------------------------------------------------
  # * 交换顺序
  #----------------------------------------------------------------------------
  def swap_order(index1, index2)
    ms_swap_order(index1, index2)
    $refresh = true
  end
end[/pre]
求高手帮忙修改脚本啊，拜谢！！！

我是个整体的窗口，就一个，在左侧

1. class Window_MapStatus < Window_Base
   
2.   #----------------------------------------------------------------------------
   
3.   # * 初始化
   
4.   #----------------------------------------------------------------------------
   
5.   def initialize
   
6.     super(0, 0, 271, 426)
   
7.     self.opacity = 255
   
8.     refresh
   
9.   end

复制代码

你这段脚本提示

1.     ($game_party.members.size - 1) times do |i|

出错，我把整个脚本给你看吧
