乒乓球穿过球拍，撞到墙上，反射而不是打在垫子上

Question

我正在做一个乒乓球游戏，它最终会有一个挡块，中间有一个类似的加农炮，既可以射球，也可以加力，最后会增加不同的功能，但现在我甚至不能让球正确地击中球拍。。。。。 导入pygame

球穿过敌人的球拍。它实际上并没有穿过它，它会挡住它，但它会越过桨。我一直在尝试不同的方法，但我是新手，正在努力。在

这是我认为给我带来麻烦的课，我没有犯任何错误，只是没有按我喜欢的方式击球。游戏者的划桨工作得很好，只是敌人没有正确地做它。在

^{pr2}$

我也在努力增加碰撞，以防球反弹。我尝试了几种不同的方法，但注意到球穿过了球拍，必须先解决这个问题。这是我的下一步。感谢任何帮助。在

我不知道我是不是说错话了。在

我尝试过创建精灵组，并以这种方式显示它们，我不知道更好的方式来显示它们，但它们仍然可以移动。。。在
