python游戏代码运行不了_PYTHON游戏编程----敲入ENTER键后游戏开始(加入按键游戏不动,去掉游戏运行)...

from tkinter import *

tk = Tk()

tk.title('李翔的第一个游戏')

tk.resizable(0, 0)

tk.wm_attributes('-topmost', 1)

canvas.pack()

tk.update()

paddle = Paddle(canvas, 'blue')

ball = Ball(canvas, paddle, 'red')

while 1:

if ball.hit_bottom == False:

if paddle.game_start == True: #MAC OS 编程触摸板怎么定义.

ball.draw()

paddle.draw()

tk.update()

tk.update_idletasks()

time.sleep(0.01)

关键代码: paddle.game_strart ==True: 这个地方是否有错误,如果错了, 思路在哪里,谢谢
