提供一个python的打飞机游戏代码

这里给您提供一个简单的Python打飞机游戏的代码，使用Pygame库实现：

import pygame
import random

# 初始化Pygame
pygame.init()

# 设置游戏窗口
screen_width = 480
screen_height = 700
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("打飞机")

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

# 加载玩家飞机图片
player_img = pygame.image.load("images/player.png").convert_alpha()
player_width, player_height = player_img.get_size()

# 加载敌机图片
enemy_img = pygame.image.load("images/enemy.png").convert_alpha()
enemy_width, enemy_height = enemy_img.get_size()

# 加载子弹图片
bullet_img = pygame.image.load("images/bullet.png").convert_alpha()
bullet_width, bullet_height = bullet_img.get_size()

# 设置字体
font = pygame.font.SysFont(None, 32)

# 定义函数：绘制文本
def draw_text(text, color, x, y):
    text_surface = font.render(text, True, color)
    screen.blit(text_surface, (x, y))

# 定义类：玩家飞机
class Player(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = player_img
        self.rect = self.image.get_rect()
        self.rect.centerx = screen_width // 2
        self.rect.bottom = screen_height - 10
        self.speed_x = 0
        self.speed_y = 0
        
    def update(self):
        self.rect.x += self.speed_x
        self.rect.y += self.speed_y
        if self.rect.left < 0:
            self.rect.left = 0
        elif self.rect.right > screen_width:
            self.rect.right = screen_width
        if self.rect.top < 0:
            self.rect.top = 0
        elif self.rect.bottom > screen_height:
            self.rect.bottom = screen_height
            
    def shoot(self):
        bullet = Bullet(self.rect.centerx, self.rect.top)
        all_sprites.add(bullet)
        bullets.add(bullet)

# 定义类：敌机
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = enemy_img
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, screen_width - enemy_width)
        self.rect.y = random.randint(-enemy_height, -10)
        self.speed_y = random.randint(1, 3)
        
    def update(self):
        self.rect.y += self.speed_y
        if self.rect.top > screen_height:
            self.kill()
            
# 定义类：子弹
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = bullet_img
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed_y = -10
        
    def update(self):
        self.rect.y += self.speed_y
        if self.rect.bottom < 0:
            self.kill()

# 创建精灵组
all_sprites = pygame.sprite.Group()
enemies = pygame.sprite.Group()
bullets = pygame.sprite.Group()

# 创建玩家飞机
player = Player()
all_sprites.add(player)

# 设置帧率
clock = pygame.time.Clock()
fps = 60

# 游戏循环
score = 0
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.KEYDOWN:
            if event.key == pygame.K_LEFT:

                player.speed_x = 5
            elif event.key == pygame.K_UP:
                player.speed_y = -5
            elif event.key == pygame.K_DOWN:
                player.speed_y = 5
            elif event.key == pygame.K_SPACE:
                player.shoot()
        elif event.type == pygame.KEYUP:
            if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                player.speed_x = 0
            elif event.key == pygame.K_UP or event.key == pygame.K_DOWN:
                player.speed_y = 0
    
    # 更新精灵组
    all_sprites.update()
    
    # 生成敌机
    if random.randint(0, 50) == 0:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    # 检测碰撞
    hits = pygame.sprite.groupcollide(enemies, bullets, True, True)
    for hit in hits:
        score += 10
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        running = False
    
    # 绘制屏幕
    screen.blit(background_img, (0, 0))
    all_sprites.draw(screen)
    draw_text("得分: " + str(score), (255, 255, 255), 10, 10)
    pygame.display.update()
    
    # 控制帧率
    clock.tick(fps)

# 结束游戏
pygame.quit()

这个游戏中，玩家控制飞机左右移动，上下移动，按空格键发射子弹，击落敌机得分，如果被敌机撞到则游戏结束。您可以根据需要进行修改和扩展。
