Question

我正在通过livewires包装器运行它，这只是一般的pygame和其他python模块的训练轮;但每次我运行它，它都会执行，当我尝试退出时，它不会响应然后崩溃。

关于我如何解决这个问题的任何意见都很棒。我的教科书中没有任何输入，所有谷歌似乎都是使用pygame本身产生的结果。

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()

类似的问题：Pygame screen freezes when I close it

我的教科书中没有任何输入所有谷歌似乎屈服于使用pygame导致这个问题本身。

这些结果可能解决了您遇到的同样问题。这是来自livewires的games.py文件的相关部分，无处调用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，使你退出mainloop函数中的while循环。我猜测如果你在Python目录中找到这个文件并在pygame.quit()的最后一行之后粘贴mainloop，它将解决你的问题。

Answer 2

我同意。你需要将整个程序（要执行的部分，而不是定义等）放入while循环。问题是pygame在IDLE退出时不会被告知关闭，但在IDLE之外，程序的关闭会覆盖需要关闭pygame。

这是循环：

done = False
while done==False:
    # ALL EVENT PROCESSING SHOULD GO BELOW THIS COMMENT
    for event in pygame.event.get(): # User did something
        if event.type == pygame.QUIT: # If user clicked close
           done=True # Flag that we are done so we exit this loop

    #Main program here

pygame.quit()

当我从IDLE运行它后尝试退出时，pygame会冻结！
