How do i duplicate and move a shape in Tkinter Canvas-CodePudding

I am aware that I have asked a similar question in the past, and the answer worked great, but I just cant get my head around how to move this shape in this specific case.

Essentially there should be multiple rows of this shape, all next to each-other, and the next row down needs to be slightly offset, and then back and forth...

I did try using points[::x] and points[x::y] to skip the values i didn't want changed, which is what I learnt from my previous question, but I cant figure out exactly how to write the code so that the shapes display as they do in the image. I have also been trying to use zip() but since I have never used it before it did not work the way I wanted it to

Below is a part of the code detailing the starting shape which needs to be duplicated.

from tkinter import *
root = Tk()
canvas = Canvas()
canvas.pack()

points = [5, 10, 15, 5, 15, 5, 25, 5, 25, 5, 35, 10, 35, 10, 25, 20, 25, 20, 15, 20]
canvas.create_polygon(points, outline="white", fill="black", width=2)

root.mainloop()

CodePudding user response：

You could duplicate and modify data in points to draw polygons in different places but it can be simpler to draw in the same place and get object ID

polygon_id = canvas.create_polygon(...)

and move it by some offset

canvas.move(polygon_id, offset_x, offset_y)

Full working code:

import tkinter as tk  # PEP8: `import *` is not preferred

root = tk.Tk()

canvas = tk.Canvas()
canvas.pack()

points = [5, 10, 15, 5, 15, 5, 25, 5, 25, 5, 35, 10, 35, 10, 25, 20, 25, 20, 15, 20]

for offset_y in range(0, 300, 30):
    for offset_x in range(0, 300, 30):
        polygon_id = canvas.create_polygon(points, outline="white", fill="black", width=2)
        canvas.move(polygon_id, offset_x, offset_y)

root.mainloop()

Another example - with row_offset:

import tkinter as tk  # PEP8: `import *` is not preferred

root = tk.Tk()

canvas = tk.Canvas()
canvas.pack()

points = [5, 10, 15, 5, 15, 5, 25, 5, 25, 5, 35, 10, 35, 10, 25, 20, 25, 20, 15, 20]

row_offset = 15 

for offset_y in range(0, 300, 15):
    for offset_x in range(0, 360, 30):
        polygon_id = canvas.create_polygon(points, outline="white", fill="black", width=2)
        canvas.move(polygon_id, offset_x row_offset, offset_y)
        
    if row_offset == 15:
        row_offset = 0
    else:
        row_offset = 15

root.mainloop()
