Pygame分段错误：分类和递归问题？

标签： python recursion menu pygame

处理此项目：https://github.com/Roland00111/Trumpocalypse/tree/Recursion/Trumpoclypse%20UI。该程序以python Trumpocalypse.py开始。

错误是：

Fatal Python error: (pygame parachute) Segmentation Fault
Aborted (core dumped)

在另一台机器上有一个关于最大递归深度的输出。有几个地方可能会发生递归。

在名为Menu的类中调用事件循环时有一个pygame。只要按下回车键，while事件循环就会停止。然后调用一个新的Menu类。然后这个新的Menu类启动一个新的while事件循环。 Menu类是主Menu类的所有子类。

由于每个新的Menu类都在上一个菜单中启动，因此可能会发生递归。

例如Menu：OpeningMenu（）运行第一个while事件循环。 然后，如果选择了第一个菜单：CreateCharacter（）运行一个新的while事件循环。 然后，如果选择了第二个项目菜单：CreateCharacterAutomatic（）运行一个新的while事件循环。 然后，如果选择了第一个菜单：StoryScreen（）运行一个新的while事件循环。 现在选择第一个项目大约60次。这在Menu：StoryScreen（）和Menu：DayScreen（）的新实例之间交替。在大约第60次之后，将发生段错误。

有趣的是，在Menu：DayScreen（）代码之前的任何地方迭代时，似乎不会发生段错误。所以从Menu：OpeningMenu（）到Menu：HighScores（）并再次无休止地返回不会导致段错误。然而，这里有趣的是：当进入Menu的第一个实例时：DayScreen（）它会立即发生段错误。也就是说，在第一次打开Menu：DayScreen（）并且确实发生了段错误时，已经设置了需要60个东西的计数器。

运行previous_menu.__del__()似乎无法解决问题。虽然这确实退出了上一个菜单，但在Menu：DayScreen（）期间仍然存在分段错误。

更新

现在看：

RuntimeError: maximum recursion depth exceeded while getting the str of an object

这是在为每个继承类菜单实现两个调用之后：

Menu.__init__(self)
previous_menu.__del__()

其中previous_menu是启动当前实例的最后一个Menu实例。这是Pygame的一个问题，还是代码在Python中调用类的问题？

重现错误：选择＆＃34;开始＆＃34;，选择＆＃34;自动＆＃34;，选择＆＃34;开始冒险＆＃34;，选择＆＃34;开始日＆＃34; ，选择＆＃34;次日＆＃34;。现在继续做＆＃34;开始日＆＃34;和＃34;第二天＆＃34;约120次（每次60次）。大约在这个时候，递归错误将会触发。

以下是完整输出：

解决方案

该类正在调用另一个类并因此递归。 （将父实例传递给子节点，以便子节点指示父节点自己结束，或者无法正常工作或未正确实现。）例如：

class Menu1():
    def __init__(self):
        Menu2(self)
class Menu2():
    def __init__(self, previous):
        previous.__del__() # Not working.

现在的解决方案是让父类指导要调用的类。例如：

class Menu1():
    def __init__(self):
        pass
class Menu2():
    def __init__(self):
        pass
a=Menu1()
a=Menu2()

这有效并且不会遇到递归问题。

答案 0 :(得分：2)

您必须重新考虑您的菜单系统。 keypressFunction子类的__init__和Menu方法会导致递归。

在Menu子类的每个__init__方法中，您调用self.keypressFunction，然后实例化第275行self.keypressArray[chosen_position](self)中的下一个Menu子类，该self.keypressFunction在其__init__中调用ItemTouchHelper再次等等，直到Python和Pygame崩溃，因为超过了1000次递归的递归限制。

以下是iminurnamez的simple finite state machine的一个很好的例子，您可以使用它来实现场景和菜单。
