pygame做飞机大战游戏

好的，下面是一个简单的飞机大战游戏的pygame代码示例，你可以参考一下：

import pygame
import random

pygame.init()

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

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

# 定义颜色
BLACK = pygame.Color(0, 0, 0)
WHITE = pygame.Color(255, 255, 255)
GREEN = pygame.Color(0, 255, 0)
RED = pygame.Color(255, 0, 0)

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

# 加载飞机图片
player_img = pygame.image.load("player.png")

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

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

# 设置字体
font = pygame.font.SysFont("arial", 36)

# 定义玩家飞机类
class Player(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = player_img
        self.rect = self.image.get_rect()
        self.rect.centerx = 240
        self.rect.bottom = 680
        self.speed = 5
        self.bullets = pygame.sprite.Group()
    
    def update(self):
        key_pressed = pygame.key.get_pressed()
        if key_pressed[pygame.K_LEFT]:
            self.rect.x -= self.speed
        if key_pressed[pygame.K_RIGHT]:
            self.rect.x += self.speed
        if key_pressed[pygame.K_SPACE]:
            bullet = Bullet(self.rect.centerx, self.rect.top)
            self.bullets.add(bullet)
    
    def draw(self, surface):
        surface.blit(self.image, self.rect)
        self.bullets.draw(surface)
    
    def shoot(self):
        bullet = Bullet(self.rect.centerx, self.rect.top)
        self.bullets.add(bullet)

# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        pygame.sprite.Sprite.__init__(self)
        self.image = bullet_img
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed = -10
    
    def update(self):
        self.rect.y += self.speed
        if self.rect.bottom < 0:
            self.kill()

# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        pygame.sprite.Sprite.__init__(self)
        self.image = enemy_img
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, 480 - self.rect.width)
        self.rect.y = random.randint(-100, -50)
        self.speed = random.randint(3, 8)
    
    def update(self):
        self.rect.y += self.speed
        if self.rect.top > 700:
            self.kill()

# 创建精灵组
all_sprites = pygame.sprite.Group()
enemies = pygame.sprite.Group()
player = Player()
all_sprites.add(player)

# 设置游戏帧率
clock = pygame.time.Clock()
FPS = 60

# 游戏循环
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
    
    # 更新玩家飞机
    player.update()
    
    # 创建敌机
    if random.randint(0, 60) == 0:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    # 更新所有精灵
    all_sprites.update()
    
    # 碰撞检测
    hits = pygame.sprite.groupcollide(enemies, player.bullets, True, True)
    for hit in hits:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    hits = pygame.sprite.spritecollide(player, enemies, False)
    if hits:
        text = font.render("Game Over", True, RED)
        screen.blit(text, (240 - text.get_rect().width // 2, 300))
        pygame.display.update()
        pygame.time.delay(2000)
        pygame.quit()
        exit()
    
    # 绘制背景
    screen.blit(bg, (0, 0))
    
    # 绘制所有精灵
    all_sprites.draw(screen)
    
    # 更新屏幕
    pygame.display.update()
    
    # 控制游戏帧率
    clock.tick(FPS)

以上是一个非常简单的飞机大战游戏的pygame代码示例，你可以根据自己的需求进行修改和完善。
