乌龟不动

Question

这是一个使用tkinter和turtle的蛇和梯子脚本。在

我的问题是柜台（海龟）不会经过23号广场，我不知道为什么。

代码很长，但我在重要区域附近添加了注释。
如果你想知道我的意思，你可以运行它

Answer 1

问题是因为turtle的位置是float，所以xcor()，ycor()给出{}值，print()显示四舍五入值，即25.0，但实际值是25.000000000000063948846218409016728401184082031250000000

你必须使用int()值即

    x = int(p1.xcor())
    y = int(p1.ycor())

并使用x，y来改变方向。

或者用手机号来改变方向。
