pythom飞机大战

以前做的时候想把这个完善一直没做
到现在也不没以前的心了就这样吧

1. alien_invasion

import pygame

from settings import Settings 
from ship import Ship
import fc

def run_game():
    pygame.init()#初始化游戏
    ai_s=Settings()
    screen=pygame.display.set_mode((ai_s.s_w,ai_s.s_h))#创建窗口，并设置大小
    pygame.display.set_caption("飞船大战")
    ship=Ship(screen)

    #开始游戏的主循环
    while True:
        fc.ck(ship)
        ship.update()
        fc.update(ai_s,screen,ship)

run_game()#调用函数

2.settings
```python
class Settings():
    def __init__(self):
        self.s_w=1200
        self.s_h=800
        self.bg_c=(230,230,230)

3. ship

        self.image=pygame.image.load('ship.bmp')#加载图片
        self.img_rect=self.image.get_rect()#获取图片矩形
        self.screen_rect=screen.get_rect()#获取屏幕矩形

        self.img_rect.centerx=self.screen_rect.centerx#获取图片矩形横坐标
        self.img_rect.bottom=self.screen_rect.bottom#获取图片矩形纵坐标
        self.speed=2#控制速度
        self.moving_right = False #运动标志
        self.moving_left = False #运动标志
        self.moving_up = False #运动标志
        self.moving_down = False #运动标志


    def update(self):

            self.img_rect.centerx-=self.speed

        if self.moving_up and self.img_rect.top>0:
            self.img_rect.centery-=self.speed

        if self.moving_down and self.img_rect.bottom

    pygame.display.flip()#让最近绘制的屏幕可见
