因此有很多问题在继续。我试图用蟒蛇制作一个蛇游戏，但这只是一团糟，所以现在我试图把它放在最初的右移动后它们可以去的唯一方向，他们必须到达坐标食物，否则它重新开始。如果他们吃'＃39;食物/广场，然后它将进入另一个级别，应该开始新的游戏，所以我可以保持得分，但是无论我在if下放置什么，成长定义似乎都不起作用。我正在使用python tkinter。

答案 0 :(得分：0)
如果要检查Tkinter画布上是否有两个对象重叠，可以通过对象Canvas .coords(objectname)的方法获取它们的位置。您可以使用.coords方法检查绘制的对象。
示例：
circle = canvas.create_oval(0, 0, 50, 50)
canvas.move(circle, 5, 0) # moves the circle by 5 pixels to the right
coords = canvas.coords(circle) # Returns an array (5, 0, 55, 0).
你要做的是指定一个坐标来返回它上面的对象（我认为你在做什么）。
