【问题描述】：

让我先说这是我第一次尝试编写 Discord 机器人。此外，在过去的几天里，我一直在努力解决这个问题，所以我的大脑感觉像糊状。话虽如此，如果其他人对此问题的答案似乎很明显，我深表歉意。

为了解释我在这里所做的事情，我的机器人用于特定的游戏，在该游戏中有一段时间我们不希望人们能够听到彼此的谈话（或不由自主地对正在发生的事情做出反应）游戏）。运行游戏的人使用命令将语音通道中的每个人静音或取消静音。该机器人在这方面工作得很好。它已经过多人多次测试。

不过，我想添加一个意外事件，因为我们不希望过早离开游戏的人最终无限期地关闭服务器（直到管理员可以对此采取措施）。我对此的回答是有一个特定的角色，当他们被静音时被分配，当他们被取消静音时被移除。然后，机器人应该在该人离开语音频道时检查该角色，如果有，请确保该角色已被删除并且该人未静音。 （这确保了如果他们因为除此机器人以外的原因而被服务器静音，他们就无法使用机器人功能来解决这个问题。）

所以这是我写的（并重写了很多次，试图让它工作）：

client.on('voiceStateUpdate', (oldState, newState) => 
    let oldServer = oldState.guild;
    let oldChannel = oldState.channel;
    let oldMember = oldState.member;
    // If user leaves a voice channel (ignores voiceStateUpdate caused by muting/unmuting in other functions).
    if (oldChannel && oldChannel !== newState.channel) 
        console.log(`$oldMember.user.tag left channel $oldChannel.name ($oldServer.name).`);
        // Check if they have the "Hushed" role.
        if (oldMember.roles.cache.some(role => role.name === 'Hushed')) 
            // Remove the "Hushed" role, if the user has it.
            let role = oldServer.roles.cache.find(role => role.name === 'Hushed');
            oldMember.roles.remove(role).catch(console.error);
            console.log(`- "Hushed" role removed from $oldMember.user.tag.`);
            // Unmute this member.
            oldMember.voice.setMute(false);
            console.log(`- User $oldMember.user.tag unmuted.`);
        
    
)

它会识别某人何时离开语音频道并知道他们是否担任该角色，因为我的 console.log 消息会打印到控制台窗口，但这似乎是功能停止的地方。它不会删除角色或取消静音用户。这是我的 console.log（出于显而易见的原因，我已经掩盖了我认为是私有的所有信息）：

MY_DISCORD_TAG left channel Testing (MY_DISCORD_SERVER).
- "Hushed" role removed from MY_DISCORD_TAG.
- User MY_DISCORD_TAG unmuted.

我对自己的代码进行编程或调试并不陌生，通常可以自己解决这些问题（通过阅读文档或在 Google 上搜索）。但是，在为此苦苦挣扎了几天之后，我没有运气。所以我决定尝试接触社区。我将不胜感激任何帮助了解导致此失败的原因。

【参考方案1】：

Discord documentation 表示，当用户不在语音频道时尝试设置用户的静音/耳聋会引发错误，因此您无法在用户离开频道后取消静音。相反，如果用户以“Hushed”角色加入频道（不在频道中之后），您可以取消静音：

client.on('voiceStateUpdate',(oldState, newState) => 
    let oldServer = oldState.guild;
    let oldChannel = oldState.channel;
    let oldMember = oldState.member;
    let newChannel = newState.channel;

    // If the user changed voice channels or the user joined a channel (after not being in one)
    if (oldChannel && newChannel && oldChannel !== newChannel || !oldChannel) 
        // Check if they have the "Hushed" role.
        if (oldMember.roles.cache.some(role => role.name === 'Hushed')) 
            // Remove the "Hushed" role, if the user has it.
            let role = oldServer.roles.cache.find(role => role.name === 'Hushed');
            oldMember.roles.remove(role)
                .then(() => 
                    // This will be logged after the role has been successfully removed.
                    // As removing roles is asynchronous, your code would have logged this
                    // regardless of whether the role was actually removed.
                    console.log(`- "Hushed" role removed from $oldMember.user.tag.`);
                    // Unmute this member.
                    return oldMember.voice.setMute(false);
                )
                .then(() => console.log(`- User $oldMember.user.tag unmuted.`))
                .catch(error => console.error(error));
            
        
    
);

使用 ES2017 的 async/await:

client.on('voiceStateUpdate', async (oldState, newState) => 
    let oldServer = oldState.guild;
    let oldChannel = oldState.channel;
    let oldMember = oldState.member;
    let newChannel = newState.channel;

    // If the user changed voice channels or the user joined a channel (after not being in one)
    if (oldChannel && newChannel && oldChannel !== newChannel || !oldChannel) 
        // Check if they have the "Hushed" role.
        if (oldMember.roles.cache.some(role => role.name === 'Hushed')) 
            // Remove the "Hushed" role, if the user has it.
            let role = oldServer.roles.cache.find(role => role.name === 'Hushed');
            try 
                await oldMember.roles.remove(role);
                console.log(`- "Hushed" role removed from $oldMember.user.tag.`);
                // Unmute this member.
                await oldMember.voice.setMute(false);
                console.log(`- User $oldMember.user.tag unmuted.`);
             catch (error) 
                console.error(error);
            
        
    
);

哇，我不敢相信我错过了。我确实说过我的大脑是糊状的！非常感谢您的帮助，这绝对是问题所在。
