向上是初始化
def line_creation(self,x,y,x1,y1): #creation of multple lines
spacing = 0
lines = [] # could list([])
for i in range(11):
id = self.canvas.create_line( x, y, x1 spacing, y1, width=2, fill="white")
lines.append(id)
spacing = 100
pos1 = self.canvas.coords(id)
self.pos1 = pos1
print(self.pos1)
return lines
這是頂點線的創建方法
def line_movement_creation(self,x,y,x1,y1):
spacing1 = 0
lines = []
for i in range(4):
id = self.canvas.create_line(x , y spacing1, x1, y1 spacing1, width=2, fill="white")
lines.append(id)
spacing1 = 100
#line = [] equal all horizontal and vertical, 12 - 15 equal horizontal moving lines
return lines
這是為水平線創建的
def line_update(self): #line movement method
for line in self.line3:
self.canvas.move(line, self.speedx, self.speedy)
#Create variables for all x and y values for the lines
pos = self.canvas.coords(line)
print(pos)
if pos[3] >= 800:
self.canvas.move(line, self.speedx, self.speedy - 460)
def move_active(self):
if self.active:
self.line_update()
self.window.after(40, self.move_active)
這就是移動線條產生運動錯覺的原因。我想獲取水平線串列并將它們設定在最外面的垂直線之間。所以它會停留在垂直線之間。創造道路般的形象。我想我需要為兩者單獨列出一份清單，但我不確定。所以為了澄清我可以幫助我告訴我如何使水平線不附加到螢屏的末端，而是在水平線內部代碼演示

uj5u.com熱心網友回復：
所以，首先我建議你使用一些游戲引擎，pygame因為它更快，并提供更多選項和其他東西，但這里有tkinter（基本上是一些簡單的三角學）：
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()
所以這里的主要方法是Canvas().draw_lines(). 首先，根據總行數以設定的間隔獲取行 ID 串列及其坐標，然后迭代它們，更改它們的y值，并相應地計算直角三角形的tan對邊和相鄰邊從當前 y 坐標和起點（中間點）可知。
