Study Python when , I saw Zhu Hongqing's 【Python Core programming from entry to development practice 】,
To my surprise 13 The code of Zhang's pinball game is actually incomplete , According to the book, it doesn't work properly .
The following code is simply adjusted , I hope later scholars can save some time .
import sys,random,time
import pygame
import pygame as game

background_image_filename = 'snow1.jpg'
# The ball
ball_color = (255,0,0)
paddle_color = (255,140,0)
ball_x = random.randint(10,590)
ball_y = 10
speed_x = 1
speed_y = 1
count = 0
score = 0
# Scoreboard
def drawText(content):
pygame.font.init()
# font size （ Any font , The same directory as this program ）
font = pygame.font.Font("sans.ttf",28)
text = font.render(content,True,(255,0,0),(255,255,255))
return text

game.draw.rect(game_window,paddle_color,(mouse_x,470,100,10))
