当某人加入特定语音频道时，向文本频道发送消息

问题描述

我正在尝试制作我的机器人，当有人进入语音支持候机室时，它会通过特定的文本通道通知我的服务器员工。

遗憾的是，我只找到了一些不一致版本12的示例，在版本13中它不适用于我。我不知道要在该代码中更改什么。

没有错误消息等，只是在有人加入语音通道时不会发送消息。

client.on('voiceStateUpdate', (oldState, newState) => {
  const newUserChannel = newState.channelID;
  const textChannel = client.channels.cache.get('931223643362703521');

  if (newUserChannel === '931156705303317013') {
    textChannel.send('Somebody joined');
  }
  console.error();
});

推荐答案

首先，确保添加了GUILD_VOICE_STATES意图。

使用fetch通道可能比依赖缓存更好。如果该频道已缓存，fetch将使用该频道，不会向Discorde接口发出请求，但如果该频道未缓存，channels.cache.get将找不到它。

我做了几处更改，并在下面的代码中添加了一些注释：

const { Client, Intents } = require('discord.js');

const client = new Client({
  intents: [
    Intents.FLAGS.GUILDS,
    Intents.FLAGS.GUILD_MESSAGES,
    Intents.FLAGS.GUILD_VOICE_STATES,
  ],
});

client.on('voiceStateUpdate', async (oldState, newState) => {
  const VOICE_SUPPORT_ID = '931156705303317013';
  const LOG_CHANNEL_ID = '931223643362703521';
  // if there is no newState channel, the user has just left a channel
  const USER_LEFT = !newState.channel;
  // if there is no oldState channel, the user has just joined a channel
  const USER_JOINED = !oldState.channel;
  // if there are oldState and newState channels, but the IDs are different,
  // user has just switched voice channels
  const USER_SWITCHED = newState.channel?.id !== oldState.channel?.id;

  // if a user has just left a channel, stop executing the code
  if (USER_LEFT)
    return;

  if (
    // if a user has just joined or switched to a voice channel
    (USER_JOINED || USER_SWITCHED) &&
    // and the new voice channel is the same as the support channel
    newState.channel.id === VOICE_SUPPORT_ID
  ) {
    try {
      let logChannel = await client.channels.fetch(LOG_CHANNEL_ID);

      logChannel.send(
        `${newState.member.displayName} joined the support channel`,
      );
    } catch (err) {
      console.error('❌ Error finding the log channel, check the error below');
      console.error(err);
      return;
    }
  }
});
