问题[pygame]

这里我的代码有问题，我想确保将有关变量的信息写入文本文件中的文件，并在下次将其写入变量时。这是我的代码：

import pygame


pygame.init()
bg = pygame.image.load("images/kira.png")
window = pygame.display.set_mode((1300, 500)) 
screen = pygame.Surface((1300, 600))
start_game = True
print("Log")
score = 0
coins = 0
f = open('whu.txt','r')

coins = f.read()
f.close()


while start_game == True:
    for i in  pygame.event.get():
        if i.type == pygame.QUIT:
            start_game = False
        if i.type == pygame.KEYDOWN and i.key == pygame.K_w:
            coins += 1
            print(coins)
        if i.type == pygame.KEYDOWN and i.key == pygame.K_d and coins == 1000:
            coins -= 1000
            score += 1
            print("Молодец! Ты заработал 1 робукс! Теперь у тебя: " + str(score) + " робуксов! Кидай скрин Владу и пиши сколько хочешь вывести!")
            








    window.blit(screen, (1,1))
    screen.blit(bg, (1,0))


    pygame.display.update()

    while True:
        with open ('whu.txt', 'r') as f:
            old_data = f.read()

        new_data = old_data.replace('0', str(coins))

        with open ('whu.txt', 'w') as f:
            f.write(new_data)
        break






pygame.quit()

如何从链接播放音乐，例如使用 pygame？

链接示例： https ://mp3minusovki.com/music/fhvndfjwserjgt/8f58cee79c35b16d1f8de40659394245/f5135242a10a5f2b7966b355846b8adb.mp3

我正在用 Python 语言 kivy 库创建一个媒体播放器。我想让用户搜索他想要的歌曲的名称并在线播放，但我不知道可以做到这一点的库。我只知道如果有 mp3 分辨率的歌曲本身的 url 链接可以很容易地做到这一点，但我还没有找到可以自动制作这样一个链接的资源。我使用 pygame 播放音乐，但该库没有我需要的功能。

我正在制作一个游戏，其中一艘船必须躲避即将到来的外星人。游戏的主类有一个功能，可以将一个新的外星人添加到组中。我想减慢这个功能，但是当我添加 sleep 命令时，整个循环变慢了。我需要外星人在给定的时间间隔出现。

我欢迎大家！我开始学习 pygame，对于我的游戏，有必要为角色制作一个附加的相机，我做到了，但现在我的代码已经有点困惑了。一般来说，你需要制作一个角色的空闲动画，我做了几次尝试，但不知何故没有成功。请告知如何做到这一点。提前致谢。这是我的代码：
