你为什么不直接丢在update里面（ΦωΦ）

case的用法搞错了，你原本的代码中只有case when 0的时候才执行第二个draw_text方法，代码改成下面这样

1.   def refresh
   
2.     self.contents.clear
   
3.     self.contents.draw_text(0, 0, 100, 24, "第#{$game_variables[98]}天")
   
4.     case $game_variables[99]
   
5.     when 3
   
6.       a1 = "深夜"
   
7.     when 2
   
8.       a1 = "夜晚"
   
9.     when 1
   
10.       a1 = "下午"
    
11.     when 0
    
12.       a1 = "上午"
    
13.     else
    
14.       a1 = nil
    
15.     end
    
16.     self.contents.draw_text(0, 32, 100, 24, a1) if a1
    
17.   end

或者这样

      self.contents.draw_text(0, 32, 100, 24, a1)
    when 0
      a1 = "上午" 
      self.contents.draw_text(0, 32, 100, 24, a1)
    end    
  end

def refresh


    self.contents.clear


    self.contents.draw_text(0, 0, 100, 24, "第#{$game_variables[98]}天")


    case $game_variables[99]


    when 3


      a1 = "深夜"


      self.contents.draw_text(0, 32, 100, 24, a1)


    when 2


      a1 = "夜晚"


      self.contents.draw_text(0, 32, 100, 24, a1)


    when 1


      a1 = "下午"


      self.contents.draw_text(0, 32, 100, 24, a1)


    when 0


      a1 = "上午" 


      self.contents.draw_text(0, 32, 100, 24, a1)


    end    


  end

另外描绘文字需要花费一定的时间，因此refresh不建议放到update里面实时刷新，只有当这两个变量发生改变的时候再刷新
