对于我的计算机课程中的一个项目，我创建了一个砖块破碎机风格的游戏，我刚刚完成编写它，但碰撞检测不起作用。当我运行程序时出现以下消息：碰撞检测问题和命令名称无效？

invalid command name "182718608Lcallit" 
    while executing 
"182718608Lcallit" 
    ("after" script)

这是什么意思？为什么不是碰撞检测功能？

好吧编辑：我有另一个稍微不同的代码版本，我知道碰撞检测正在工作，但只有得分改变，砖块不消失，球不反弹。我不明白为什么这个版本有一个工作分数，而第一个版本没有，我不明白为什么这两个代码都不能成功删除砖块并弹跳球。此代码也有类似的错误消息，只有不同的数字。有人可以解释，我是新来的编码。

你collisionDetect方法删除一块砖，但你尝试做的事情与砖后（在你的代码的if didWeHit部分）。确保你等待删除砖块，直到你完成了所有你需要的东西！

在Tkinter中，如果您尝试对已删除的对象执行某些操作，则会发生此类错误。 Tkinter为每个创建的Tk对象分配一个数字，这是您得到的错误中的有趣数字。它试图执行命名为182718608Lcallit的命令，但由于您删除了相应的块，所以不再存在。
