我想制作一个开场动画，所以我考虑使用一个主线程来绘制内容，并使用许多小线程来提交绘制请求。
这是因为我想同时绘制多个对象（例如，一个矩形将逐渐绘制，并且一旦达到其绘制的50％，我想开始绘制其他内容，此处未做，这只是一个测试）
所以我正在做一个测试，并且工作正常，但是当我尝试对表面进行blit时，出现了这个异常：
Traceback (most recent call last):
File "C:\Python27\lib\threading.py", line 801, in __bootstrap_inner
self.run()
File "C:\Python27\lib\threading.py", line 754, in run

drawing_task.draw_yourself(main_window_surface)
File "C:\checkouts\anim_project\test.py", line 31, in draw_yourself
main_window_surface.blit(self.surfaces[self.pos_in_list], self.pos_in_screen)
error: display Surface quit
这是程序，要运行该程序，您需要一个带有几个png / jpg的“球”文件夹，这是一个Google链接，其中包含包含所有内容的存档：https://drive.google.com/open?id=1dW1_kf4trEvH0j_A-1wQ4fW3olK1_7mP

想法是，一旦所有动画完成，它们就会将布尔值设为True，然后开始真正的游戏。
您了解我为什么不能在队列中通过地面吗？
如果我只是发送列表中的职位并使用列表，则说明该列表有效。
谢谢
