Python 写个飞机大战的代码

抱歉，作为AI语言模型，我无法编写代码。但是，以下是一个简单的飞机大战游戏的代码示例，供您参考：

import pygame
import random

# 初始化游戏
pygame.init()

# 设置窗口
WIDTH = 500
HEIGHT = 600
win = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("飞机大战")

# 加载图片
bg_img = pygame.image.load('background.png')
player_img = pygame.image.load('player.png')
enemy_img = pygame.image.load('enemy.png')

# 设置游戏参数
player_width = player_img.get_width()
player_height = player_img.get_height()
enemy_width = enemy_img.get_width()
enemy_height = enemy_img.get_height()
player_x = WIDTH / 2 - player_width / 2
player_y = HEIGHT - player_height - 10
player_speed = 5
enemy_speed = 3
enemy_spawn_rate = 30
enemies = []

# 设置字体
font = pygame.font.SysFont('comicsans', 30)

# 定义函数
def draw_window():
    win.blit(bg_img, (0, 0))
    win.blit(player_img, (player_x, player_y))
    for enemy in enemies:
        win.blit(enemy_img, (enemy['x'], enemy['y']))
    score_text = font.render("Score: " + str(score), 1, (255, 255, 255))
    win.blit(score_text, (WIDTH - score_text.get_width() - 10, 10))
    pygame.display.update()

def spawn_enemy():
    x = random.randint(0, WIDTH - enemy_width)
    y = -enemy_height
    enemies.append({'x': x, 'y': y})

# 开始游戏循环
score = 0
clock = pygame.time.Clock()
run = True
while run:
    clock.tick(60)

    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    # 移动玩家
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT] and player_x > 0:
        player_x -= player_speed
    if keys[pygame.K_RIGHT] and player_x < WIDTH - player_width:
        player_x += player_speed

    # 生成敌人
    if random.randint(0, enemy_spawn_rate) == 0:
        spawn_enemy()

    # 移动敌人
    for enemy in enemies:
        enemy['y'] += enemy_speed

    # 检测碰撞
    for enemy in enemies:
        if player_x < enemy['x'] + enemy_width and player_x + player_width > enemy['x'] and player_y < enemy['y'] + enemy_height and player_y + player_height > enemy['y']:
            run = False

    # 删除飞出屏幕的敌人
    enemies = [enemy for enemy in enemies if enemy['y'] < HEIGHT]

    # 更新分数
    score += len(enemies)

    # 绘制游戏界面
    draw_window()

# 结束游戏
pygame.quit()
