How to attach a line to a moving object?

[lightning18]

Hello i have designed a maze and i want to draw a path between the cells as the 'person' moves from one cell to the next. So each time i move the cell a line is drawn Also i am using the graphics module

The graphics module is an object oriented library

Im importing

from graphics import*
from maze import*

my circle which is my cell

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())
this is my loop
 
 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

Now it says getX not defined every time i press a key is this because of p2???

ive found this in the module about Point

class Point(GraphicsObject)
Method resolution order:
    Point
    GraphicsObject
    builtins.object
 
Methods defined here:
 
__init__(self, x, y)
 
clone(self)
 
getX(self)
 
getY(self)

Without seeing your code for "Circle", I have no way of knowing what your problem is other than you did not define a method "center()".

@bvdet
ey ive just shown u the code for circle its right there lol andi have edited my question of my post and my code
# c is my circle

[bvdet]

You are calling getX() as though it is a stand-alone function when it is actually a Point object method. Try this:

p2 = Point(c.getCenter().getX(), c.getCenter().getY())

@bvdet
thanx bvdet i did what u said but now i get another error which is

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Python31\lib\tkinter\__init__.py", line 1399, in __call__
    return self.func(*args)
  File "C:\Python31\mazefiddle.py", line 38, in handleKeys
    p2 = Point(c.getCenter.getX(), c.getCenter().getY())
AttributeError: 'function' object has no attribute 'getX'

Any ideas why still a getX error whys dat?

Look carefully:

p2 = Point(c.getCenter().getX(), c.getCenter().getY())

You are not calling getCenter().

@bvdet
what you mean iam not calling getCenter? it is in my p1 and p2 shouldnt it be called already?
how do i call something then?
I also changed my code for the p2 bit

@lightning18
Take a look at this code, and tell me if you see any difference between "p.uv" and "p.uv()".

>>> p = Pt3D(1,2,3)
>>> p.uv
<bound method Pt3D.uv of Pt3D(1.000000, 2.000000, 3.000000)>
>>> p.uv()
Pt3D(0.267261, 0.534522, 0.801784)
>>> 

"p.uv" returns the method bound to instance "p" and "p.uv()" calls method "uv()". The difference is the parentheses.

@bvdet
so is this what you are saying ?
if i have
(

p1 = Point(c.getcenter().getX(), c.getcenter.getY())
p2 = Point(p1.getcenter().getX(), p1.getcenter().getY()

or you saying

p1.p2()

something like that
i understand it but do not know whot to implement it with my code bit confused how mine needs to be like that
thanks

[bvdet]

p2 = Point(c.getCenter.getX(), c.getCenter().getY())

The line of code above should be

p2 = Point(c.getCenter().getX(), c.getCenter().getY())

You left out the parentheses after "c.getCenter".
