这就是移动线条产生运动错觉的原因。我想把水平线的列表放在最外层的垂直线之间。所以它会在两条直线之间。创建一个类似道路的图像。我想我需要为两者单独列一个清单，但我不确定。因此，为了澄清，我可以有人帮助告诉我如何使水平线不连接到屏幕的末端，而是连接到水平线内部代码演示

所以，首先我建议你使用一些游戏引擎，如pygame，因为它更快，提供了更多的选项和其他东西，但这里是tkinter(基本上是一些简单的三角函数):
import tkinter as tk
import math
class Canvas(tk.Canvas):
def __init__(self, parent, width=700, height=500, **kwargs):
super().__init__(parent, width=width, height=height, **kwargs)
self.width = width
self.height = height
self.angle = 70
self.speedy = 10
self.change_speed_ms = 50
self.draw_angle(self.angle, 5)
self.lines, self.interval = self.init_lines(amount=5)
self.draw_lines()
@property
def radians(self):
return math.radians(self.angle)
def draw_angle(self, view_angle, lines):
orient = 0
adjacent = self.height // 2
step = view_angle // lines
half = view_angle // 2
for angle in range(orient - half, orient + half + step, step):
rad = math.radians(angle)
delta = math.tan(rad) * adjacent
x1, y1 = self.width // 2, self.height // 2
x2, y2 = x1 + delta, y1 + adjacent
self.create_line(x1, y1, x2, y2)
def init_lines(self, amount=5):
interval = round((self.height // 2) / amount)
coordinate_list = list()
offset = self.height // 2
for y in range(0, self.height // 2 + interval, interval):
delta = math.tan(self.radians / 2) * y
x1 = self.width // 2 - delta
x2 = self.width // 2 + delta
y1 = y2 = y + offset
line = self.create_line(x1, y1, x2, y2)
coordinate_list.append((line, (x1, y1, x2, y2)))
return coordinate_list, interval
def draw_lines(self):
tmp_lst = list()
for id_, (x1, y1, x2, y2) in self.lines:
y1 += self.speedy
if y1 > self.height + self.interval - self.speedy:
y1 = self.height // 2
y = y2 = y1
adjacent = y - self.height // 2
delta = math.tan(self.radians / 2) * adjacent
x1 = self.width // 2 - delta
x2 = self.width // 2 + delta
self.coords(id_, x1, y1, x2, y2)
tmp_lst.append((id_, (x1, y1, x2, y2)))
self.lines = tmp_lst
self.after(self.change_speed_ms, self.draw_lines)
root = tk.Tk()
Canvas(root, highlightthickness=0).pack()
root.mainloop()
所以这里的主要方法是Canvas().draw_lines()。首先，你得到一个线id列表和它们的坐标，基于总线的数量，在设定的间隔，然后你迭代它们，改变它们的y值，并相应地计算直角三角形的对边，使用tan和从当前y坐标和起点(中间)已知的邻边。
