我按照书上的的代码打的为什么一直有问题

zltzlt

class Settings:
    def _int_(self):
        self.screen_width = 1200
        self.screen_height = 800
        self.bg_color = (230,230,230)


应该是 __init__，不是 _int_。

1. import sys
   
2. import pygame
   
3. from settings import Settings
   
4. from ship import Ship
   
5. 
   
6. def run_game():
   
7.     pygame.init()
   
8.     ai_settings = Settings()
   
9.     screen = pygame.display.set_mode(
   
10.         (ai_settings.screen_width,ai_settings.screen_height))
    
11.    
    
12.     pygame.display.set_caption("Alien Invasion")
    
13.     #创建一艘飞船
    
14.     ship = Ship(screen)
    
15. 
    
16. 
    
17.     while True:
    
18.         for event in pygame.event.get():
    
19.             if event.type==pygame.QUIT:
    
20.                 sys.exit()
    
21.         screen.fill(be_color)
    
22.         screen.fill(ai_settings.bg_color)
    
23.         ship.blite()
    
24.         pygame.display.flip()
    
25.         
    
26. run_game()
    
27. 
    
28. 
    
29. 
    
30. class Settings:
    
31.     def __init__(self):
    
32.         self.screen_width = 1200
    
33.         self.screen_height = 800
    
34.         self.bg_color = (230,230,230)

改了 Settings 类吗？

1. class Settings:
   
2.     def __init__(self):
   
3.         self.screen_width = 1200
   
4.         self.screen_height = 800
   
5.         self.bg_color = (230,230,230)
