【问题描述】：
我是一名 Python 初学者，我正在使用 Pygame 制作一个简单的 2D 游戏。除了使用 pygame.Rect 函数进行碰撞检查外，我几乎完成了。我正在尝试在“碰撞检测”评论下检查与 car2 和 car 的碰撞，但我得到 - TypeError: Invalid rectstyle argument。我为此研究了很长时间，但我无法在我的代码中使用它。如果有人帮助解决此问题，我将不胜感激。

【问题讨论】：
-
AttributeError: 'pygame.Rect' 对象没有属性 'top_left'
-
但现在我收到一条错误消息，提示“pygame.Rect”对象不可调用
