用python帮我写一个飞机大战的游戏

好的，我可以为您提供一个简单的飞机大战游戏的代码。以下是代码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口的尺寸
WINDOW_WIDTH = 480
WINDOW_HEIGHT = 800
WINDOW_SIZE = (WINDOW_WIDTH, WINDOW_HEIGHT)

# 创建游戏窗口
screen = pygame.display.set_mode(WINDOW_SIZE)

# 设置游戏窗口标题
pygame.display.set_caption("Plane War")

# 加载游戏素材
bg_img = pygame.image.load("images/bg.jpg").convert()
plane_img = pygame.image.load("images/plane.png").convert_alpha()
bullet_img = pygame.image.load("images/bullet.png").convert_alpha()
enemy_img = pygame.image.load("images/enemy.png").convert_alpha()
boom_img = pygame.image.load("images/boom.png").convert_alpha()

# 设置游戏字体
font = pygame.font.SysFont("arial", 24)

# 设置游戏音效
pygame.mixer.music.load("sounds/bg.mp3")
pygame.mixer.music.set_volume(0.2)
pygame.mixer.music.play(-1)
bullet_sound = pygame.mixer.Sound("sounds/bullet.wav")
bullet_sound.set_volume(0.2)
enemy_down_sound = pygame.mixer.Sound("sounds/enemy_down.wav")
enemy_down_sound.set_volume(0.2)

# 定义游戏变量
score = 0
plane_rect = plane_img.get_rect()
plane_rect.centerx = WINDOW_WIDTH // 2
plane_rect.bottom = WINDOW_HEIGHT - 20
bullet_list = []
enemy_list = []
boom_list = []
enemy_speed = 1
enemy_add_counter = 0
enemy_down_counter = 0
game_over = False

# 定义函数：绘制分数
def draw_score():
    score_text = font.render("Score: {}".format(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))

# 定义函数：绘制飞机
def draw_plane():
    screen.blit(plane_img, plane_rect)

# 定义函数：绘制子弹
def draw_bullet():
    for bullet in bullet_list:
        screen.blit(bullet_img, bullet)

# 定义函数：绘制敌机
def draw_enemy():
    for enemy in enemy_list:
        screen.blit(enemy_img, enemy)

# 定义函数：绘制爆炸
def draw_boom():
    for boom in boom_list:
        screen.blit(boom_img, boom)

# 定义函数：生成敌机
def generate_enemy():
    random_left = random.randint(0, WINDOW_WIDTH - enemy_img.get_width())
    enemy_rect = enemy_img.get_rect()
    enemy_rect.left = random_left
    enemy_rect.bottom = 0
    enemy_list.append(enemy_rect)

# 定义函数：移动子弹
def move_bullet():
    for bullet in bullet_list:
        bullet.move_ip(0, -10)
        if bullet.bottom < 0:
            bullet_list.remove(bullet)

# 定义函数：移动敌机
def move_enemy():
    global game_over
    for enemy in enemy_list:
        enemy.move_ip(0, enemy_speed)
        if enemy.top > WINDOW_HEIGHT:
            enemy_list.remove(enemy)
            game_over = True

# 定义函数：检测碰撞
def check_collision():
    global score, enemy_down_counter
    for bullet in bullet_list:
        for enemy in enemy_list:
            if bullet.colliderect(enemy):
                bullet_list.remove(bullet)
                enemy_list.remove(enemy)
                enemy_down_counter = 5
                boom_list.append(enemy)
                enemy_down_sound.play()
                score += 10

# 定义函数：播放爆炸
def play_boom():
    global enemy_down_counter
    for boom in boom_list:
        screen.blit(boom_img, boom)
        enemy_down_counter -= 1
        if enemy_down_counter == 0:
            boom_list.remove(boom)

# 游戏循环
while True:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN and event.key == pygame.K_SPACE:
            bullet_list.append(pygame.Rect(plane_rect.centerx - 3, plane_rect.top - 10, 6, 10))
            bullet_sound.play()
        elif event.type == pygame.KEYDOWN and event.key == pygame.K_ESCAPE:
            pygame.quit()
            exit()

    # 绘制背景
    screen.blit(bg_img, (0, 0))

    # 绘制分数
    draw_score()

    # 绘制飞机
    draw_plane()

    # 绘制子弹
    draw_bullet()

    # 绘制敌机
    draw_enemy()

    # 绘制爆炸
    draw_boom()

    # 生成敌机
    enemy_add_counter += 1
    if enemy_add_counter == 50:
        generate_enemy()
        enemy_add_counter = 0

    # 移动子弹
    move_bullet()

    # 移动敌机
    move_enemy()

    # 检测碰撞
    check_collision()

    # 播放爆炸
    play_boom()

    # 更新屏幕
    pygame.display.update()

    # 判断游戏是否结束
    if game_over:
        game_over_text = font.render("Game Over", True, (255, 0, 0))
        screen.blit(game_over_text, (WINDOW_WIDTH // 2 - 60, WINDOW_HEIGHT // 2 - 12))
        pygame.display.update()
        pygame.time.delay(2000)
        break

游戏素材和音效需要自行准备，放在与代码相同的目录下。运行代码后，按空格键发射子弹，避免敌机撞到自己。
