Python 拖放兵
我有一个棋盘。我会有兴趣在不同的情况下拖拽每一个棋子，但我不知道如何才能做到这一点。我曾想过使用我的_canvas.bind、move，但我不确定如何在上面的代码中使用它。现在，我只能看到不同的白色和黑色，无法移动它们Python 拖放兵,python,tkinter,canvas,bind,Python,Tkinter,Canvas,Bind,我有一个棋盘。我会有兴趣在不同的情况下拖拽每一个棋子，但我不知道如何才能做到这一点。我曾想过使用我的_canvas.bind、move，但我不确定如何在上面的代码中使用它。现在，我只能看到不同的白色和黑色，无法移动它们 如何在棋盘上拖放棋子？您所要做的就是从您在问题的早期版本中链接到的问题中投票率最高的答案中复制一些代码，然后调整绑定以处理标记块而不是令牌 首先，将函数drag_start、drag_stop和drag_stop从代码中复制到CanvasChecker类中。在复制的代码中将sel
如何在棋盘上拖放棋子？您所要做的就是从您在问题的早期版本中链接到的问题中投票率最高的答案中复制一些代码，然后调整绑定以处理标记块而不是令牌 首先，将函数drag_start、drag_stop和drag_stop从代码中复制到CanvasChecker类中。在复制的代码中将self.canvas更改为self 接下来，在_init__函数中的某个位置添加此行：

@布莱恩·奥克利这是一个糟糕的答案，因为你只是在指导OP做什么，而没有详细说明。@Space:为什么？如果您让我知道，也许我可以把答案做得更好。@Space：精化在复制代码的内联注释中。OP知道存在一个更好的答案，但在将代码应用到他们的代码时有某种心理障碍。从他们对评论的回答中似乎很清楚，他们永远也不会明白。我知道OP已经链接到他们删除的答案，你不必解释游戏的机制，而是解释他们的代码失败的原因和地方。@Space:他们的代码中没有失败的地方。即使在我询问之后，他们也拒绝显示试图移动对象的代码。
