python - 当我从 IDLE 运行它后尝试退出它时，pygame 卡住了!

Question

我正在通过 livewires 包装器运行它，它通常只是 pygame 和其他 python 模块的训练轮；但每次我运行它时，它都会执行，当我尝试退出时，它不会响应然后崩溃。

任何关于我如何解决这个问题的意见都会很棒。我的教科书中没有任何输入，谷歌似乎产生的所有结果都是使用 pygame 本身解决这个问题的结果。

显然 pygame 和 Tkinter 似乎有冲突？

提前致谢!

附录 - 这是我试图运行的代码:

from livewires import games

screen_w = 640
screen_h = 480

my_screen = games.Screen (wid, heit)
my_screen.mainloop()

类似问题:Pygame screen freezes when I close it

There isn't any input in my textbook and all google seems to yield are results to this problem using pygame itself.

这些结果可能解决了您遇到的相同问题。这是来自 livewires 的 games.py 文件的相关部分，它没有调用 pygame.quit():

def handle_events (self):
    """
    If you override this method in a subclass of the Screen
    class, you can specify how to handle different kinds of
    events.  However you must handle the quit condition!
    """
    events = pygame.event.get ()
    for event in events:
        if event.type == QUIT:
            self.quit ()
        elif event.type == KEYDOWN:
            self.keypress (event.key)
        elif event.type == MOUSEBUTTONUP:
            self.mouse_up (event.pos, event.button-1)
        elif event.type == MOUSEBUTTONDOWN:
            self.mouse_down (event.pos, event.button-1)

def quit (self):
    """
    Calling this method will stop the main loop from running and
    make the graphics window disappear.
    """

    self._exit = 1

def mainloop (self, fps = 50):
    """
    Run the pygame main loop. This will animate the objects on the
    screen and call their tick methods every tick.

    fps -- target frame rate
    """

    self._exit = 0

    while not self._exit:
        self._wait_frame (fps)

        for object in self._objects:
            if not object._static:
                object._erase ()
                object._dirty = 1

        # Take a copy of the _objects list as it may get changed in place.
        for object in self._objects [:]:
            if object._tickable: object._tick ()

        self.tick ()

        if Screen.got_statics:
            for object in self._objects:
                if not object._static:
                    for o in object.overlapping_objects ():
                        if o._static and not o._dirty:
                            o._erase ()
                            o._dirty = 1

        for object in self._objects:
            if object._dirty:
                object._draw ()
                object._dirty = 0

        self._update_display()

        self.handle_events()

    # Throw away any pending events.
    pygame.event.get()

QUIT 事件只是设置一个标志，使您退出 mainloop 函数中的 while 循环。我猜如果你在你的 Python 目录中找到这个文件并在 mainloop 的最后一行之后添加一个 pygame.quit()，它会解决你的问题。
