问题描述

我想让机器人播放一段音频，当音频结束时，它会重播音频.

I want to make a bot play a piece of audio and, when the audio finishes, it will replay the audio.

我有什么:

@client.command()
async def play(ctx):
await ctx.channel.purge(limit=1)
channel = ctx.author.voice.channel
if channel:
    print(channel.id)
    await channel.connect()
guild = ctx.guild
audio_source = discord.FFmpegPCMAudio('audio.mp3')
voice_client: discord.VoiceClient = discord.utils.get(client.voice_clients, guild=guild)
if not voice_client.is_playing():
    voice_client.play(audio_source, after=None)

解决方案

discord.VoiceClient.Play() 有一个 after 参数，在音频流结束时调用.通常，它应该用于显示错误消息，但您可以使用它来重复歌曲，如下所示:

discord.VoiceClient.Play() has an after parameter that is called when the audio stream ends. Normally, it should be used to display error messages but you can use it to repeat the song like so:

@client.command()
async def play(ctx):
    await ctx.channel.purge(limit=1)
    channel = ctx.author.voice.channel
    voice = get(self.bot.voice_clients, guild=ctx.guild)

    def repeat(guild, voice, audio):
        voice.play(audio, after=lambda e: repeat(guild, voice, audio))
        voice.is_playing()

    if channel and not voice.is_playing():
        audio = discord.FFmpegPCMAudio('audio.mp3')
        voice.play(audio, after=lambda e: repeat(ctx.guild, voice, audio))
        voice.is_playing()
