Pygame:如何在玩家死亡后将背景重置到新位置

# 初始化Pygame

# 设置游戏窗口
width = 800
height = 600
window = pygame.display.set_mode((width, height))
pygame.display.set_caption("游戏名称")

# 加载背景图片

# 玩家是否死亡的标志

        self.rect = self.image.get_rect()
        self.rect.center = (width // 2, height // 2)

    def update(self):

            # 玩家死亡后的重置操作
            self.rect.center = (random.randint(0, width), random.randint(0, height))
            player_dead = False

    def draw(self):
        window.blit(self.image, self.rect)

# 创建玩家对象
player = Player()
all_sprites = pygame.sprite.Group()
all_sprites.add(player)

# 游戏主循环
running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    # 更新玩家状态
    player.update()

    # 绘制背景
    window.blit(background_img, (0, 0))

    # 绘制玩家
    all_sprites.draw(window)
    
    pygame.display.flip()

# 退出游戏
pygame.quit()
