python pygame模块 打飞机游戏

Posted 2020-10-04

settings.py用于设置屏幕的基本设置

# -*- coding: gbk -*- 
__author__ = ‘HZQ‘
import  pygame
class  Settings():
    ‘‘‘
    存储所有设置
    ‘‘‘
    def  __init__(self):

        self.pwd=‘E:\\\\Python35\\\\images\\\\bg.jpg‘

        self.ship_speed_factor = 1.5
    def bg(self):
        background = pygame.image.load(self.pwd).convert()
        return background

Update_Screen.py设置屏幕背景
