如何在迷宫求解应用中绘制“轨迹”

Question

你好，我设计了一个迷宫，我想在“人”从一个单元格移动到另一个单元格时，画出一条路径。每次我移动单元格时，就会画一条线。同时，我在使用图形模块。

图形模块是一个面向对象的库。

我正在导入

from graphics import*
from maze import*

我的圆形代表我的单元格

center = Point(15, 15)
c = Circle(center, 12)
c.setFill('blue')
c.setOutline('yellow')
c.draw(win)

p1 = Point(c.getCenter().getX(), c.getCenter().getY())

这是我的循环

 if mazez.blockedCount(cloc)> 2: 
            mazez.addDecoration(cloc, "grey")
            mazez[cloc].deadend = True
        c.move(-25, 0)
        p2 = Point(p1.getX(), p1.getY())
        line = graphics.Line(p1, p2)
        cloc.col = cloc.col - 1

现在每次我按一个键时，它都说getX未定义，这是不是因为p2的问题？？

这是这个模块中最重要的部分
