以python初学者的身份写一个非常简单的飞机小游戏

好的，我可以为您提供一个简单的飞机小游戏示例。您可以在此基础上自行进行修改和扩展。

import pygame
import random

# 初始化pygame
pygame.init()

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

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

# 加载飞机图片
plane_img = pygame.image.load('images/plane.png')
plane_rect = plane_img.get_rect()
plane_width = plane_rect.width
plane_height = plane_rect.height
plane_x = (screen_width - plane_width) // 2
plane_y = screen_height - plane_height - 50

# 加载子弹图片
bullet_img = pygame.image.load('images/bullet.png')
bullet_rect = bullet_img.get_rect()
bullet_width = bullet_rect.width
bullet_height = bullet_rect.height

# 加载敌机图片
enemy_imgs = [
    pygame.image.load('images/enemy1.png'),
    pygame.image.load('images/enemy2.png'),
    pygame.image.load('images/enemy3.png')
]
enemy_rects = [img.get_rect() for img in enemy_imgs]
enemy_widths = [rect.width for rect in enemy_rects]
enemy_heights = [rect.height for rect in enemy_rects]

# 设置游戏字体
font = pygame.font.Font(None, 36)

# 初始化游戏分数
score = 0

# 初始化子弹列表和敌机列表
bullets = []
enemies = []

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

        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE:
                # 发射子弹
                bullet_x = plane_x + plane_width // 2 - bullet_width // 2
                bullet_y = plane_y - bullet_height
                bullets.append(pygame.Rect(bullet_x, bullet_y, bullet_width, bullet_height))

    # 检测键盘事件
    pressed_keys = pygame.key.get_pressed()
    if pressed_keys[pygame.K_LEFT]:
        plane_x -= 5
    if pressed_keys[pygame.K_RIGHT]:
        plane_x += 5
    if pressed_keys[pygame.K_UP]:
        plane_y -= 5
    if pressed_keys[pygame.K_DOWN]:
        plane_y += 5

    # 控制飞机不出界
    if plane_x < 0:
        plane_x = 0
    if plane_x > screen_width - plane_width:
        plane_x = screen_width - plane_width
    if plane_y < 0:
        plane_y = 0
    if plane_y > screen_height - plane_height:
        plane_y = screen_height - plane_height

    # 更新子弹位置
    for bullet in bullets:
        bullet.y -= 10
        if bullet.y < -bullet_height:
            bullets.remove(bullet)

    # 添加敌机
    if random.randint(1, 60) == 1:
        enemy_img = random.choice(enemy_imgs)
        enemy_rect = enemy_img.get_rect()
        enemy_width = enemy_rect.width
        enemy_height = enemy_rect.height
        enemy_x = random.randint(0, screen_width - enemy_width)
        enemy_y = -enemy_height
        enemies.append(pygame.Rect(enemy_x, enemy_y, enemy_width, enemy_height))

    # 更新敌机位置
    for enemy in enemies:
        enemy.y += 5
        if enemy.y > screen_height:
            enemies.remove(enemy)

    # 检测子弹和敌机碰撞
    for bullet in bullets:
        for enemy in enemies:
            if bullet.colliderect(enemy):
                bullets.remove(bullet)
                enemies.remove(enemy)
                score += 10

    # 绘制界面
    screen.blit(bg, (0, 0))
    screen.blit(plane_img, (plane_x, plane_y))
    for bullet in bullets:
        screen.blit(bullet_img, bullet)
    for enemy in enemies:
        enemy_img = enemy_imgs[enemy_rects.index(enemy)]
        screen.blit(enemy_img, enemy)
    score_text = font.render('Score: %d' % score, True, (255, 255, 255))
    screen.blit(score_text, (10, 10))
    pygame.display.update()

您可以将上述代码保存为一个文件，如`plane_game.py`，并在终端中运行该文件。游戏窗口将会打开，并且您可以通过方向键控制飞机的移动，空格键发射子弹。在游戏中，敌机将从屏幕上方不断进入，您需要尽可能地消灭它们并获得更高的分数。
