python - tkinter 多边形

Question

我对 tkinter 比较陌生，我正在制作一个只使用正方形的游戏。我正在抄写的书只显示三角形。这是代码:

# The tkinter launcher (Already complete)
from tkinter import *
HEIGHT = 500
WIDTH = 800
window = Tk()
window.title ('VOID')
c = Canvas (window, width=WIDTH, height=HEIGHT, bg='black')
c.pack()
# Block maker (Issue)
ship_id = c.create_polygon (5, 5, 5, 25, 30, 15, fill='red')

我没有收到任何错误，它只是一串数字，(5, 5, 5, 25, 30, 15) 我没有收到，因为我试图做一个正方形。

Answer 1

摘要Canvas.create_polygon definition :

As displayed, a polygon has two parts: its outline and its interior. Its geometry is specified as a series of vertices [(x0, y0), (x1, y1), … (xn, yn)] (...)

id = C.create_polygon(x0, y0, x1, y1, ..., option, ...)

所以你需要按照这个指定的顺序传递正方形的坐标。例如:

myCanvas.create_polygon(5, 5, 5, 10, 10, 10, 10, 5)

可以理解为

myCanvas.create_polygon(5,5, 5,10, 10,10, 10,5)

将创建一个正方形，其顶点为 (5, 5)、(5, 10)、(10, 10) 和 (10, 5)。
