我正在尝试创建一个外星人入侵游戏,但我遇到了一个障碍,让我的主文件从我的设置类导入设置。下面是我的代码,首先是我的alien_invasion主文件,然后是我的设置类:
import sys
import pygame
from settings import Settings
def run_game():
#Initialize game and create a screen object.
pygame.init()
ai_settings = Settings()
screen = pygame.display.set_mode(
(ai_settings.screen_width, ai_settings.screen_height))
#Start the main loop for the game.
while True:
#Watch for keyboard and mouse events.
for event in pygame.event.get():
if event.type == pygame.QUIT:
sys.exit()
#Redraw the screen during each pass through the loop.
screen.fill(ai_settings.bg_color)
#Make the most recently drawn screen visible
pygame.display.flip()
run_game()
class Settings():
"""A class to store all for Alien Invasion."""
def __int__(self):
"""Initialize the game's settings."""
#Screen settings
self.screen_width = 1200
self.screen_height = 800
self.bg_color (230, 230, 230)
尝试运行时,我得到以下内容:
Traceback (most recent call last):
File "alien_invasion.py", line 28, in <module>
run_game()
File "alien_invasion.py", line 12, in run_game
(ai_settings.screen_width, ai_settings.screen_height))
AttributeError: 'Settings' object has no attribute 'screen_width'
有什么想法吗?

输入错误导致此问题,您在SELECT DISTINCT a.nom_voie, b.nom_voie, ST_Intersection(a.geom, b.geom)
课程i
中遗漏了Settings
。
为了澄清,Python中的缩写__init__
代表Integer数据类型。 int
是&#34;初始化&#34;的缩写。

我相信您可以使用以下方法解决此问题:
来自设置导入*
只要您没有任何重叠变量,并且settings.py和main.py位于同一目录中,这应该可以。
