我有一个tkinter框架和2个精灵，当我在墙的确切位置时，可以轻松地使vel = 0。问题是，在精灵内（我需要角色在碰到墙的边缘时停下来）。

我已经在这个头发上拉了一段时间了。如果有人可以提供帮助，那就太好了！预先感谢！

不确定您是否已解决问题，但是由于遇到了与此相同的徒劳的事情，因此，我想分享一下我的想法。 请记住，Tkinter不是专门为这种事情而制作的，而像Pygame这样的东西会是更好的选择。
简单方法： 如果您的精灵是一个简单的精灵（如正方形），则只需在每个方向上将其稍微指向您的精灵，然后在每次移动时检查该点是否与墙重叠。 示例：如果您的精灵为25x25，则您可以将中心设为x，y，然后将右侧用于碰撞检测的点设为x + 26，y。那么左边可能是x-26，y。 这里的问题是您在框架中使用标签，因此要么必须找出带有错误和错误的位置，要么使用.bbox方法。
稍微复杂一些的方法（但最终更简单）： 如果您的子图形有些奇怪，并且您希望它更精确，则可以将其放在“画布”上而不是“框架”上。这使您可以选择绘制一个可以在精灵周围跟踪的多边形。然后让它随精灵一起移动，然后简单地检查它是否与墙，敌人，子弹，陷阱或您能想到的其他东西重叠。这将为您提供更大的灵活性。
如果您想做更复杂的事情，画布通常也是一个更好的选择，因为它使您可以更轻松地移动事物，绘制形状，设置标签等。如果需要，您仍然可以在画布上放置标签，按钮和所有好东西，除非您只是将东西包装在其中，否则无需使用框架。
最后，我强烈建议使用类，这将使您的生活变得更加轻松，这是该语言的主要优势之一。一开始他们可能会有些混乱，但是值得花很多时间来学习很多遍。一旦适应了它们，您会想知道如果没有它们，如何做任何事情。
