Question

我试图设计一个基于简单选择的视频游戏。基本上我想要的是一个递归循环，它将继续根据前一个结果调用新的级别。例如，在基于级别1的关闭选择中，它将触发级别2或3.这是我到目前为止的代码：

class Levels:

    def __init__(self, Next = 1):
        self.Next = Next

    def Call(self):
        VarLevel = "Level" + "{}".format(self.Next)
        return ("{}".format(VarLevel))

这是超类，它返回VarLevel，它等于Level1以触发子类Level1。这是我对关卡的代码，我已经排除了游戏的背景，因为我认为没有必要。

class Level1(Levels):

    def __init__(self,):
        # this just includes information about the level to show the user
        # (objective etc.)

    def Action(self):
        # this will include the content of the level. based off the choices
        # made I want it to return to the super with VarLevel as Level2 or 
        # Level3 and then to trigger the next level running and repeat 
        # throughout the program to run the game. For the purpose of testing 
        # the program the only content of Level1 is setting the return to 2 so 
        # that Level2 is called. I'm having trouble actually getting it to 
        # recognize my return and to trigger the next level. This is the 
        # actual method I want to do the calling with 

class LevelCall():

    def __init__(self, Levels = Levels):
        self.Levels = Levels
    def Calling(self):
        result = (Levels, "{}".format(Levels()))()

它给了我错误TypeError: 'tuple' object is not callable。我已经做了很多不同的尝试让它工作，所以我不确定这甚至是代码的真正问题。另外值得注意的是我在Java方面很不错，现在正在转向Python（这是我在Python中的第一次尝试，然后是读/写等基本测试。）非常感谢任何帮助，以帮助弄清楚如何格式化游戏，我道歉提前因为我知道这是一个很长的问题，我以前从未在这里发布过，所以如果您需要更多信息或说明，请随时提出。

编辑：这是完整的错误消息

Traceback (most recent call last):
 line 54, in <module>  
    Tester.Calling()  
  line 50, in Calling  
    result = (Levels, "{}".format(Levels()))()  
TypeError: 'tuple' object is not callable

另一个编辑：我想我越来越近了。我做了以下更改

 class LevelCall():  
      def __init__(self, Levels = Levels):  
          self.Levels = Levels  
      def Calling(self):  
          Hold = Levels()  
          result = (getattr(Levels, "{}".format(Hold.Call()))())

现在提供以下错误消息。

Traceback (most recent call last):  
  line 55, in <module>  
    Tester.Calling()  
line 51, in Calling  
    result = (getattr(Levels, "{}".format(Hold.Call()))())  
AttributeError: type object 'Levels' has no attribute 'Level1'

如果我理解正确，它现在正在尝试做我想要的但是没有找到“Level1”类。再次感谢所有帮助。

编辑______________________ 我要感谢所有回复并试图提供帮助的人，我非常感谢你的支持。通过澄清，您可以帮助我以及今天重新开始，并首先将其映射到java中以使转换更容易，我能够解决我的问题。再次非常感谢你，我将添加我在此编辑下找到的解决方案。

global Stop 
class Level1 :
    def __init__(self):
        self

    def Action(self):
        print ("1")
        global Stop
        Stop = input("Would you like to advance to the next level?")
        if (Stop == "yes"):
            # Lev = Level2()
            # return Lev.Action()
            return Level2
        if (Stop == "no"):
            return "stop"



class Level2:
    def __init__(self):
        self

    def Action(self):
        print("2")
        global Stop
        Stop = input("Would you like to advance to the next level?")
        if (Stop == "yes"):
            # Lev = Level3()
            # return Lev.Action()
            return Level3
        if (Stop == "no"):
            return "stop"

class Level3 :
    def __init__(self):
        self

    def Action(self):
        print ("3")
        global Stop
        Stop = input ("Next level??")
        if (Stop == "yes"):
            # Lev = Level4()
            # return Lev.Action()
            return Level4
        if (Stop == "no"):
            return "stop"

class Level4:
    def __init__(self):
        self

    def Action(self):
        print ("Complete")
        return "Done"

def Runner (Level):
    if (Level == "Done"):
        print ("Bye")
    else :
        if (Level != "stop"):
            Lev = Level()
            Next = Lev.Action()
            Runner(Next)

        if (Level == "stop"):
            print ("you chose to stop")




Runner(Level1)

(a,b,c)是元组语法。 (a,b,c)()是一个被称为函数的元组。这就是错误所指的内容。

如果我们打破违规代码，你可以告诉我们。将format的调用替换为arg占位符后，它会是什么样子：
(Levels, "{}".format(Levels()))()变成...... (Levels, arg)() # this is now clearly a tuple and you're treating it like a function.

不确定如何修复可以帮助你解决关卡问题。

如果您想调用某个功能，请执行以下操作：func(args) 如果要定义元组，请执行以下操作：(a, b, ..., z) 但是不要把元组称为函数。

如何递归调用视频游戏级别的不同方法？
