如何退出战斗系统？

Question

我一直在努力通过Python的艰难的方式书，它提出了写作战系统的挑战

我想知道如何打破'赢''条款或移动到下一个场景的while循环。
目前，游戏在用户'死亡'时起作用，但在击败对手双方时，游戏以错误消息结束。

File "fight_test.py", line 146, in <module> 
    a_game.play() 
File "fight_test.py", line 20, in play 
    next_scene_name = current_scene.enter() 
AttributeError: 'NoneType' object has no attribute 'enter'

while health > 0 and (customer1 or customer2): 
      #While loop runs whilst health > 0 and one of the customers remains. 
      print "\n", "-" * 20 
      your_attack = randint(4,12) 
      customer1_attack = randint(1,4) 
      customer2_attack = randint(3,6) 
      if customer2_hitpoints == 0 and customer1_hitpoints == 0: 
       return 'Win' 

      attack = int(raw_input("Type 1 to attack Customer 1, 2 to attack Customer 2 >")) 
      if attack == 1: 
       if customer1: 
        customer1_hitpoints = customer1_hitpoints - your_attack 
        print "You refuse service to Customer 1, %d damage." % your_attack 
        if customer1_hitpoints <= 0: 
         customer1 = False 
         print "Customer 1 is removed from the building." 
       else: 
        print "Customer 1 has already been removed and left an angry Trip Advisor review." 
      elif attack == 2: 
       if customer2: 
        customer2_hitpoints = customer2_hitpoints - your_attack 
        print "You tell customer 2 that they have had too much already, %d damage." % your_attack 
        if customer2_hitpoints <= 0: 
         customer2 = False 
         print "Customer 2 falls over and throws up, they are promptly removed from the building." 
       else: 
        print "They have already left to get a late night burger." 
      else: 
       print "Why are you just doing nothing?" 

      if customer1: 
       health = health - customer1_attack 
       print "Customer 1 tells you that the service is better in Wetherspoons." 
       print "It causes %d damage and you have d% health left." % (customer1_attack, health) 
       if health <= 0: 
        return 'death' 
        break 

      if customer2: 
       health = health - customer2_attack 
       #print Fight.quotes[randint(0, len(self.quips)-1)] 
       print "The customer tells you \"This isn't how I make this drink at home!\"" 
       print "It causes %d damage and you have %d health left." % (customer2_attack, health) 
       if health <= 0: 
        return 'death' 
        break 

Answer 1

您正在进入战斗，我相信，和death可以在某些时候它可能会加载该场景被退回......

scenes = { 
    'fight' : Fight(), 
    'death' : Death() 
} 

How might I implement a method to exit the while loop in such a case and move to another scene/print a win statement?

怎么样将'Win' : Win()添加到场景图中？

关于错误

AttributeError: 'NoneType' object has no attribute 'enter'

您还可能要为None（不'None'）场景或检查当前场景中存在

if not current_scene: 
    print "Done!" 
    exit(0) 
next_scene_name = current_scene.enter() 

而且，这实际上是检查是否的customer2还活着并且客户1已经死了

if customer2_hitpoints and customer1_hitpoints == 0: 

你需要明确检查两者是否为零
