生成一个飞机大战python代码

以下是一个简单的飞机大战Python代码示例，你可以在此基础上进行修改和扩展：

import pygame
import random

# 初始化pygame
pygame.init()

# 设置游戏窗口大小和标题
WINDOW_WIDTH = 480
WINDOW_HEIGHT = 800
WINDOW_TITLE = '飞机大战'
screen = pygame.display.set_mode((WINDOW_WIDTH, WINDOW_HEIGHT))
pygame.display.set_caption(WINDOW_TITLE)

# 加载背景和飞机图片
bg_img = pygame.image.load('images/bg.jpg')
player_img = pygame.image.load('images/player.png')
enemy_img = pygame.image.load('images/enemy.png')
bullet_img = pygame.image.load('images/bullet.png')

# 设置游戏时钟和帧率
clock = pygame.time.Clock()
FPS = 60

# 飞机类
class Plane(pygame.sprite.Sprite):
    def __init__(self, img, x, y, speed):
        super().__init__()
        self.image = img
        self.rect = self.image.get_rect()
        self.rect.x = x
        self.rect.y = y
        self.speed = speed

    def update(self):
        self.rect.y += self.speed

# 玩家类
class Player(Plane):
    def __init__(self, img, x, y, speed):
        super().__init__(img, x, y, speed)
        self.bullets = pygame.sprite.Group()

    def update(self):
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT]:
            self.rect.x -= self.speed
        if keys[pygame.K_RIGHT]:
            self.rect.x += self.speed
        if keys[pygame.K_SPACE]:
            bullet = Bullet(bullet_img, self.rect.centerx, self.rect.top)
            self.bullets.add(bullet)

# 敌机类
class Enemy(Plane):
    def __init__(self, img, x, y, speed):
        super().__init__(img, x, y, speed)

# 子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, img, x, y):
        super().__init__()
        self.image = img
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed = -10

    def update(self):
        self.rect.y += self.speed
        if self.rect.bottom < 0:
            self.kill()

# 创建玩家和敌机精灵组
player = Player(player_img, WINDOW_WIDTH // 2, WINDOW_HEIGHT - 100, 5)
enemies = pygame.sprite.Group()

# 游戏主循环
while True:
    # 处理游戏事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()

    # 更新玩家和敌机
    player.update()
    enemies.update()

    # 添加新的敌机
    if random.randint(1, 60) == 1:
        enemy = Enemy(enemy_img, random.randint(0, WINDOW_WIDTH - 50), -50, random.randint(1, 5))
        enemies.add(enemy)

    # 检测玩家和敌机是否碰撞
    if pygame.sprite.spritecollide(player, enemies, False):
        pygame.quit()
        exit()

    # 检测子弹和敌机是否碰撞
    for bullet in player.bullets:
        if pygame.sprite.spritecollide(bullet, enemies, True):
            bullet.kill()

    # 绘制游戏界面
    screen.blit(bg_img, (0, 0))
    screen.blit(player.image, player.rect)
    player.bullets.draw(screen)
    enemies.draw(screen)

    # 更新游戏界面
    pygame.display.update()

    # 控制游戏帧率
    clock.tick(FPS)

在运行该代码之前，需要先准备好游戏需要用到的图片素材，并将其放置在代码中对应的路径下。
