机器人加入并在公会的所有语音频道播放文件

Question

我最近一直在制作我的第一个 discord 机器人，今天我遇到了一个小问题。我需要我的机器人连接到服务器的所有语音通道并播放 mp3 文件。用于提醒消息。

我首先使用此代码进行了基本测试，以在启动命令的用户所连接的频道中播放 mp3：

exports.run = async (client, message, args, level) => {
  if (message.member.voiceChannel) {
    message.member.voiceChannel.join()
    .then(connection => {
        const dispatcher = connection.playFile('/home/pi/.discordbots/TARVIS/1.mp3');
        dispatcher.on("end", end => {message.member.voiceChannel.leave()});
    })
    .catch(console.error);
  }
};

上面的代码工作正常

所以我尝试为所有语音频道制作它:

  let voiceChannels = message.guild.channels.filter(channel => channel.type == 'voice');

  voiceChannels.forEach(channel =>
    channel.join()
      .then(connection => {
        const dispatcher = connection.playFile('/home/pi/.discordbots/TARVIS/1.mp3');
        dispatcher.on("end", end => { channel.leave() });
      })
      .catch(console.error)
  );

问题是机器人连接到第一个频道，然后直接连接到第二个频道，没有时间播放第一个频道中的文件。

我想我得看看client.createVoiceBroadcast();方法。我尝试使用它，但找不到很好的例子。这是我尝试过的方法，但它也不起作用：

exports.run = (client, message, args, level) => {
  let voiceChannels = message.guild.channels.filter(channel => channel.type == 'voice');
  const broadcast = client.createVoiceBroadcast();
  broadcast.playFile('/home/pi/.discordbots/TARVIS/1.mp3');

  voiceChannels.forEach(channel =>
    channel.join()
      .then(connection => {
        const dispatcher = connection.playBroadcast(broadcast);
        dispatcher.on("end", end => { channel.leave() });
      })
      .catch(console.error)
  );

预期结果是机器人在每个语音通道中连接，一个接一个地播放 mp3 文件。

提前感谢您的帮助

我尝试制作一个异步函数并在 connection.playFile() 上使用等待，但我仍然遇到同样的问题。 Bot连接所有语音通道，但不等待文件播放。

这是我试过的代码：

exports.run = async (client, message, args, level) => {

  async function play(voiceChannel) {
    console.log(voiceChannel.name + ` Type:` + voiceChannel.type + ` (` + voiceChannel.id + `)`);
    voiceChannel.join().then(async function (connection) {
      dispatcher = await connection.playFile('/home/pi/.discordbots/TARVIS/sncf.mp3');
      dispatcher.on('end', function () {
        voiceChannel.leave()
      });
    });
  }
  let voiceChannels = message.guild.channels.filter(channel => channel.type == 'voice');

  voiceChannels.map(vc => play(vc));

};

我很确定解决方案就在附近......但我被卡住了......有人可以帮我找到正确的语法吗？

这是我尝试使用您的解决方案的方法：

exports.run = async (client, message, args, level) => {

  async function play(voiceChannels) {
    for (let channel of voiceChannels) {
      console.log('Joining channel ' + channel.name);

      await channel.join().then(async (connection) => {
        console.log('Joined channel');

        let dispatcher = connection.playFile('/home/pi/.discordbots/TARVIS/sncf.mp3');
        await dispatcher.on('end', function () {
          channel.leave();
        });
      });
    }
  }

  let channels = message.guild.channels.filter(channel => channel.type == 'voice');
  console.log(channels);
  play(channels);

};

我可能已经找到（某种程度上）解决方案。我试图在 JSFiddle 中重现这个问题，这样我就可以更轻松地对其进行测试。 Here is my solution.

核心代码在函数joinChannels中，也可以在下面看到

async function joinChannels () {
  for (let channel of channels) {
    await new Promise((resolve) => {
      console.log('Joining channel ' + channel.name);

      resolve(new Promise((resolve) => {
        setTimeout(() => {
          console.log('Done with channel ' + channel.name);
          resolve();
        }, 1000);
      }));
    });
  }
}

现在根据您的上下文将其重写为解决方案，这是我的尝试（未经测试，因此可能需要一些调整）

async function play(voiceChannels) {
  for (let channel of voiceChannels) {
    console.log('Joining channel ' + channel.name);

    await channel.join().then(async (connection) => {
      console.log('Joined channel');

      let dispatcher = connection.playFile('/home/pi/.discordbots/TARVIS/sncf.mp3');
      await dispatcher.on('end', function () {
        voiceChannel.leave();
      });
    });
  }
}

试一试，让我知道结果如何。如果您有任何疑问，我很乐意为您提供帮助

这是我的解决方法。我使用 setTimeout 将通道语音排队，定时器为 10 秒我知道有点脏但它有效

exports.run = async (client, message, args, level) => {

  async function play(channel) {
    await channel.join().then(async (connection) => {
      let dispatcher = await connection.playFile('/home/pi/.discordbots/TARVIS/offline.m4a');
      await dispatcher.on('end', function () {
        channel.leave();
      });
    });
  }

  let timer = 1000;
  client.ShowSuccess('Démarrage des annonces vocales');
  message.guild.channels.forEach(async (channel) => {
    if (channel.type == 'voice' && channel.members.size > 0) {
      client.ShowSuccess('Annonce dans le salon ' + channel.name + ' pour ' + channel.members.size + ' membre(s)', message.channel);
      client.logger.log('Annonce dans le salon ' + channel.name + ' pour ' + channel.members.size + ' membre(s)');
      setTimeout(function () {
        play(channel);
      }, timer);
      timer = timer + 10000;
    }
  });
  setTimeout(function () {
    client.ShowSuccess('Annonces vocales terminées');
  }, timer);
};
