我如何为我尝试制作的 Discord 机器人修复此错误？

Question

我正在尝试用 JavaScript 创建一个 Discord 机器人，它为加入语音频道的每个特定人播放指定的声音。这有点像介绍音效/歌曲。

当我尝试对其进行测试时出现此错误。当我加入语音频道并且机器人没有加入语音频道播放声音时，它会在终端中输出。

cd "C:\javacode\Discord Audio Bot"
node Audio.js

输出：

On
C:\javacode\Discord Audio Bot\Audio.js:29
  } else if (newState.channel.members.size = 1) {
                              ^

TypeError: Cannot read properties of null (reading 'members')

    at WebSocket.emit (node:events:513:28)

这是我下面的代码。另外，我将如何去做才能让每个用户都有自己不同的声音？

console.log('On');
const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({
  intents: [
    GatewayIntentBits.GuildVoiceStates,
    GatewayIntentBits.GuildMembers
  ]

});

client.on('voiceStateUpdate', (_oldState, newState) => {
  // Check if the user who joined is the specific user we want
  if (newState.member.id === 'STtheGamer') {
      // Check if the user joined a voice channel
      if (newState.channel) {
          // Join the voice channel and play the specific sound
          newState.channel.join()
              .then(connection => {
                  // Replace 'song.mp3' with the path to the audio file you want to play
                  const dispatcher = connection.play('C:\Users\storr\Music\botsounds\swtheme.mp3');

                  // Leave the voice channel after the sound is played
                  dispatcher.on('finish', () => {
                      newState.channel.leave();
                  });
              })
              .catch(console.error);
      }
  } else if (newState.channel.members.size = 1) {
      if (newState.channel) {
          newState.channel.leave()
              .catch(console.error);
      }
  }

});

client.login('botkey here');

您的代码中音频文件的路径似乎有问题。您提供的路径不是有效路径，因为它在目录之间包含反斜杠 () 而不是正斜杠 (/)。在 JavaScript 中，字符串中的反斜杠需要用另一个反斜杠进行转义，所以正确的路径应该是这样的：

const dispatcher = connection.play('C:\Users\storr\Music\botsounds\swtheme.mp3');

或者，您可以使用正斜杠而不是反斜杠来分隔路径中的目录，如下所示：

const dispatcher = connection.play('C:/Users/storr/Music/botsounds/swtheme.mp3');

为了让每个用户都有自己的声音，您可以创建用户 ID 到音频文件路径的映射，然后使用此映射为每个用户查找正确的音频文件：

const introSoundUser = {
   'user1ID' : 'audiofile.path',
   'user2ID' : 'audiofile.path'
};
