Python 我能'；t多次单击同一对象

我目前正在用python制作一个吉他英雄式的游戏，我试图多次

blit

a note，但我似乎无法让它工作（note称为Red）

您正在同一周期内多次清理和更新屏幕

在每个循环中清洁屏幕是正确的方法，但是您只需要清洁一次，否则您将删除之前所显示的所有内容

此外，为了让注释在周期之间持久化，您需要将它们保存在一个集合中，就像注释一样，这样您就可以在每个周期中blit每个注释

请记住主循环中的顺序：

控制FPS（clock.tick（））

检查事件

更新状态（即：添加/删除笔记集合等）

清屏

绘制当前状态（注释、静态元素等）

更新显示

---

另一件重要的事情是，不要在不同的位置使用相同的Sprite（）或相同的矩形。如果要在新位置绘制同一图像的另一个副本，请复制矩形，然后创建一个新的Sprite（）对象。

我似乎无法让它工作

到底发生了什么？请说得更具体一些。我无法让便条（红色）在被“击中”后返回屏幕顶部。
