Question

#萌新向各位好心的大佬求教
import sys

import pygame

from settings import Settings

def run_game():
#初始化pygame，设置和屏幕对象
pygame.init()
ai_settings = Settings()
screen = pygame.display.set_mode((ai_settings.screen_width,ai_settings.screen_height))
pygame.display.set_caption("Alien Invasion")

#开始游戏的主循环   
while True:

#初始化pygame.设置和屏幕对象
    # 监视键盘和鼠标事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            sys.exit()

    #每次循环时都重绘制屏幕
    scree.fill(ai_settings.bg_color)

    #让最近的绘制的屏幕可见
    pygame.display.flip()

run_game()

#按教程书编写的模块
class Settings():
"""储存《外星人入侵》的所有设置的类"""

def _init_(self,screen_width,screen_height,bg_color):
    """初始化游戏的设置"""
    #屏幕设置
    self.screen_width = 1200

    self.screen_height = 800

    self.bg_color = (230,230,230)

#一运行就报错

    screen = pygame.display.set_mode((ai_settings.screen_width,ai_settings.screen_height))

AttributeError: 'Settings' object has no attribute 'screen_width'

#由衷的感谢大佬的帮助

Answer 1

set_mode的参数是一个元组，所以应该是set_mode((self.settings.screen_width, self.settings.screen_height))
