python 写一个飞机大战游戏源码

非常感谢您的提问，以下是一个简单的飞机大战游戏的 Python 源码：

import pygame
import random

# 初始化 Pygame
pygame.init()

# 设置游戏窗口大小
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))

# 设置游戏标题
pygame.display.set_caption("飞机大战")

# 加载背景图片
background = pygame.image.load("images/background.png")

# 加载飞机图片
player_img = pygame.image.load("images/player.png")
player_rect = player_img.get_rect()
player_rect.centerx = screen_width // 2
player_rect.bottom = screen_height - 10

# 加载子弹图片
bullet_img = pygame.image.load("images/bullet.png")
bullet_rect = bullet_img.get_rect()

# 加载敌机图片
enemy_img = pygame.image.load("images/enemy.png")
enemy_rect = enemy_img.get_rect()

# 设置字体
font = pygame.font.SysFont(None, 48)

# 设置游戏状态
game_over = False

# 设置计分
score = 0

# 设置敌机列表
enemies = []
for i in range(5):
    enemy_rect = enemy_img.get_rect()
    enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
    enemy_rect.top = random.randint(-screen_height, 0)
    enemies.append(enemy_rect)

# 游戏循环
while not game_over:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            game_over = True

    # 移动玩家飞机
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        player_rect.move_ip(-5, 0)
    if keys[pygame.K_RIGHT]:
        player_rect.move_ip(5, 0)
    if keys[pygame.K_UP]:
        player_rect.move_ip(0, -5)
    if keys[pygame.K_DOWN]:
        player_rect.move_ip(0, 5)

    # 移动子弹
    for bullet_rect in bullets:
        bullet_rect.move_ip(0, -10)
        if bullet_rect.bottom < 0:
            bullets.remove(bullet_rect)

    # 移动敌机
    for enemy_rect in enemies:
        enemy_rect.move_ip(0, 5)
        if enemy_rect.top > screen_height:
            enemy_rect.left = random.randint(0, screen_width - enemy_rect.width)
            enemy_rect.top = random.randint(-screen_height, 0)

    # 检测碰撞
    for enemy_rect in enemies:
        if player_rect.colliderect(enemy_rect):
            game_over = True
        for bullet_rect in bullets:
            if bullet_rect.colliderect(enemy_rect):
                score += 1
                enemies.remove(enemy_rect)
                bullets.remove(bullet_rect)

    # 绘制游戏界面
    screen.blit(background, (0, 0))
    screen.blit(player_img, player_rect)
    for bullet_rect in bullets:
        screen.blit(bullet_img, bullet_rect)
    for enemy_rect in enemies:
        screen.blit(enemy_img, enemy_rect)
    score_text = font.render("Score: " + str(score), True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
    pygame.display.update()

# 结束游戏
pygame.quit()
