如何解决我抓鸡蛋之后，一切都会停止
我试图在“ check_catch”函数的最后一行之后放置移动鸡蛋，但是它运行的如此之快，只创建了两个鸡蛋 我从一本书中复制了此代码，它是一个捕蛋器，但是当您抓到第一个鸡蛋后，一切立即停止。 有人知道这个问题吗？我认为问题出在哪里。它可能在“ check_catch”函数中，但我无法解决的任何问题

解决方法
在提高分数中，您可以通过将具有难度系数的多义字符更改为egg_speed。
因此，在抓到第一个鸡蛋后，速度为50000。
尝试找到一种降低egg_speed的方法！
,通过设置difficulty_factor = 100，您将极大地暂停游戏，因为您正在使用它来更改inincrease_score(points)中鸡蛋的速度：
egg_speed = int(egg_speed * difficulty_factor)
egg_interval = int(egg_interval * difficulty_factor)
将difficulty_factor更改为0.8或0.9之类的值，设置的越低越快，游戏运行良好。将其设置为1以上会导致每次迭代的鸡蛋变慢
