我一直在制作一个带有各种场景的RPG，我可以去。我想在我的所有场景上都有一个相同大小的窗口，这样在较大的窗口上，当我的角色走向屏幕边缘时，窗口将滚动到屏幕的另一部分。

您只需省略滚动条，并确保画布的scrollregion属性包含您绘制的所有内容。然后，您可以通过编程方式调用xview和yview方法来滚动。
这篇文章的最后是一个可运行的例子。运行它，在窗口中单击，然后使用光标键移动红色方块。请注意，当它到达边缘时，它将导致画布滚动。
这不是良好编码技术的一个例子。我在整个地方都有硬编码的数字，但希望它说明了如何以编程方式滚动画布。取消这一点的主要关键是：
scrollregion xview和yview方法滚动画布此代码适用于python 2.x;要让它在3.x上工作，你只需要更改import语句。
