飞机大战（Python）

  飞机大战（Python）代码分为两个python文件，工具类和主类，需要安装pygame模块，能完美运行（网上好多不完整的，调试得心累。实现出来，成就感还是满满的），如图所示：

  完整代码如下：
1.工具类plane_sprites.py

import random
import pygame

# 屏幕大小的常量
SCREEN_RECT = pygame.Rect(0, 0, 480, 700)
# 刷新的帧率
FRAME_PER_SEC = 60
# 创建敌机的定时器常量
CREATE_ENEMY_EVENT = pygame.USEREVENT
# 英雄发射子弹事件
HERO_FIRE_EVENT = pygame.USEREVENT + 1

class GameSprite(pygame.sprite.Sprite):
    """飞机大战游戏精灵"""
    def __init__(self, image_name, speed=1):
        super().__init__()# 调用父类的初始化方法
        self.image = pygame.image.load(image_name)# 定义对象的属性
        self.rect = self.image.get_rect()
        self.speed = speed
    def update(self):
        # 在屏幕的垂直方向上移动
        self.rect.y += self.speed
class Background(GameSprite):
    """游戏背景精灵"""
    def __init__(self, is_alt=False):

        if is_alt:# 2. 判断是否是交替图像，如果是，需要设置初始位置
            self.rect.y = -self.rect.height
    def update(self):
        super().update()# 1. 调用父类的方法实现
        if self.rect.y >= SCREEN_RECT.height:# 2. 判断是否移出屏幕，如果移出屏幕，将图像设置到屏幕的上方
            self.rect.y = -self.rect.height
class Enemy(GameSprite):
     """敌机精灵"""
     def __init__(self):
         super().__init__("C:/Users/Administrator/Desktop/enemy1.png")# 1. 调用父类方法，创建敌机精灵，同时指定敌机图片
         self.speed = random.randint(1, 3)# 2. 指定敌机的初始随机速度 1 ~ 3
         self.rect.bottom = 0# 3. 指定敌机的初始随机位置
         max_x = SCREEN_RECT.width - self.rect.width

     def update(self):
         super().update()# 1. 调用父类方法，保持垂直方向的飞行
         # 2. 判断是否飞出屏幕，如果是，需要从精灵组删除敌机
         if self.rect.y >= SCREEN_RECT.height:
             self.kill()
             # print("飞出屏幕，需要从精灵组删除...")
             # kill方法可以将精灵从所有精灵组中移出，精灵就会被自动销毁

     def __del__(self):

        elif self.rect.right > SCREEN_RECT.right:
            self.rect.right = SCREEN_RECT.right
    def fire(self):
        print("发射子弹...")
        for i in (0, 1, 2):
            bullet = Bullet()
            bullet.rect.bottom = self.rect.y - i * 20
            bullet.rect.centerx = self.rect.centerx
            self.bullets.add(bullet)
