当有人加入或离开其语音频道时，让机器人向文本频道发送消息

Question

我想让我的机器人向刚刚进入其语音通道或刚刚离开其语音通道的文本通道发送消息。我是编码新手，但我已经尝试过，但它不起作用。

bot.on('voiceStateUpdate', (oldMember, newMember) => {
  let newUserChannel = newMember.voiceChannel;
  let oldUserChannel = oldMember.voiceChannel;
  if (oldUserChannel === undefined && newUserChannel !== undefined) {
    if (newUserChannel === bot.voiceChannel) {
      console.log("Hello");
    }
  } else if (newUserChannel === undefined) {
  }
});

控制台中甚至什么都没有显示。

我认为这不起作用，因为您使用的是 bot.voiceChannel，但它不存在：.voiceChannel 是 GuildMember 的属性，因此您需要先获取成员。
我会这样做：

bot.on('voiceStateUpdate', (oldMember, newMember) => {
  // Here I'm storing the IDs of their voice channels, if available
  let oldChannel = oldMember.voiceChannel ? oldMember.voiceChannel.id : null;
  let newChannel = newMember.voiceChannel ? newMember.voiceChannel.id : null;
  if (oldChannel == newChannel) return; // If there has been no change, exit

  // Here I'm getting the bot's channel (bot.voiceChannel does not exist)
  let botMember = oldMember.guild.member(bot.user),
    botChannel = botMember ? botMember.voiceChannel.id : null;

  // Here I'm getting the channel, just replace VVV this VVV with the channel's ID
  let textChannel = oldMember.guild.channels.get('CHANNEL_ID_HERE');
  if (!textChannel) throw new Error("That channel does not exist.");

  // Here I don't need to check if they're the same, since it would've exit before
  if (newChannel == botChannel) {
    // console.log("A user joined.");
    textChannel.send(`${newMember} has joined the voice channel.`);
  } else if (oldChannel == botChannel) {
    // console.log("A user left.");
    textChannel.send(`${newMember} has left the voice channel.`);
  }
});
