python飞机大战代码

以下是一个简单的 Python 飞机大战的代码示例：

import pygame
import random

# 初始化 Pygame
pygame.init()

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

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

# 加载游戏背景
BACKGROUND_IMAGE = pygame.image.load('background.png').convert()

# 加载玩家飞机图片
PLAYER_IMAGE = pygame.image.load('player.png').convert_alpha()

# 加载敌机图片
ENEMY_IMAGE = pygame.image.load('enemy.png').convert_alpha()

# 加载子弹图片
BULLET_IMAGE = pygame.image.load('bullet.png').convert_alpha()

# 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):
        super().__init__()
        self.image = PLAYER_IMAGE
        self.rect = self.image.get_rect()
        self.rect.centerx = WINDOW_WIDTH // 2
        self.rect.bottom = WINDOW_HEIGHT - 10
        self.speed = 8
        
    def update(self):
        # 移动玩家飞机
        keys = pygame.key.get_pressed()
        if keys[pygame.K_LEFT] and self.rect.left > 0:
            self.rect.x -= self.speed
        if keys[pygame.K_RIGHT] and self.rect.right < WINDOW_WIDTH:
            self.rect.x += self.speed
            
        # 发射子弹
        if keys[pygame.K_SPACE]:
            bullet = Bullet(self.rect.centerx, self.rect.top)
            all_sprites.add(bullet)
            bullets.add(bullet)
        
# 定义敌机类
class Enemy(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.image = ENEMY_IMAGE
        self.rect = self.image.get_rect()
        self.rect.x = random.randint(0, WINDOW_WIDTH - self.rect.width)
        self.rect.y = random.randint(-100, -40)
        self.speed = random.randint(3, 6)
        
    def update(self):
        # 移动敌机
        self.rect.y += self.speed
        
        # 删除超出屏幕的敌机
        if self.rect.top > WINDOW_HEIGHT:
            self.kill()
        
# 定义子弹类
class Bullet(pygame.sprite.Sprite):
    def __init__(self, x, y):
        super().__init__()
        self.image = BULLET_IMAGE
        self.rect = self.image.get_rect()
        self.rect.centerx = x
        self.rect.bottom = y
        self.speed = -10
        
    def update(self):
        # 移动子弹
        self.rect.y += self.speed
        
        # 删除超出屏幕的子弹
        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

# 设置敌机生成间隔
ENEMY_INTERVAL = 60

# 设置得分
score = 0

# 游戏循环
running = True
while running:
    # 处理事件
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    
    # 生成敌机
    if random.randint(1, ENEMY_INTERVAL) == 1:
        enemy = Enemy()
        all_sprites.add(enemy)
        enemies.add(enemy)
    
    # 更新精灵组
    all_sprites.update()
    
    # 判断子弹是否击中敌机
    hits = pygame.sprite.groupcollide(bullets, enemies, True, True)
    for hit in hits:
        score += 10
    
    # 判断敌机是否撞到玩家飞机
    hits = pygame.sprite.spritecollide(player, enemies, True)
    if hits:
        running = False
    
    # 绘制游戏界面
    WINDOW_SURFACE.blit(BACKGROUND_IMAGE, (0, 0))
    all_sprites.draw(WINDOW_SURFACE)
    score_text = FONT.render('Score: {}'.format(score), True, (255, 255, 255))
    WINDOW_SURFACE.blit(score_text, (10, 10))
    pygame.display.update()
    
    # 控制帧率
    clock.tick(FPS)

# 显示游戏结束界面
game_over_text = FONT.render('Game Over', True, (255, 0, 0))
game_over_rect = game_over_text.get_rect()
game_over_rect.centerx = WINDOW_WIDTH // 2
game_over_rect.centery = WINDOW_HEIGHT // 2
WINDOW_SURFACE.blit(game_over_text, game_over_rect)
pygame.display.update()

# 延迟3秒后退出游戏
pygame.time.delay(3000)

# 退出 Pygame
pygame.quit()

注意，这只是一个简单的示例，实际的游戏可能需要更多的功能和优化。
