当所有人都断开连接时，如何删除临时语音通道？

Question

我编写了这样的代码，如果有人连接到特定频道，机器人会用他们的名字创建一个频道，然后将他们移动到其中。我希望机器人在该用户断开连接并且没有其他人连接到该频道时自动删除该频道。我有这个代码，但我不知道如何删除频道。

bot.on('voiceStateUpdate', (oldMember, newMember) =>{
    let mainCatagory = '604259561536225298';
    let mainChannel = '614954752693764119';
    if(newMember.voiceChannelID === mainChannel){
        newMember.guild.createChannel(`${newMember.user.username}'s Channel`,'voice')
        .then(temporary => {
            temporary.setParent(mainCatagory)
            .then(() => newMember.setVoiceChannel(temporary.id))
        }).catch(err =>{
            console.error(err);
        })
    }
});

我试图做if(newMember.voiceChannel.members.size === 0){temporary.detele};，但temporary 没有定义。

创建一个数组以在事件正文前写入临时频道的 ID 和创建此频道的服务器。

 var temporary = []

 bot.on('voiceStateUpdate', (oldMember, newMember) =>{
     const mainCatagory = '604259561536225298';
     const mainChannel = '614954752693764119';

     if(newMember.voiceChannelID == mainChannel){
        // Create channel...
         await newMember.guild.createChannel(`${newMember.user.username}'s channel`, {type: 'voice', parent: mainCatagory})
             .then(async channel => {
                 temporary.push({ newID: channel.id, guild: channel.guild })
                 // A new element has been added to temporary array!
                 await newMember.setVoiceChannel(channel.id)
             })
     }

     if(temporary.length >= 0) for(let i = 0; i < temporary.length; i++) {
         // Finding...
         let ch = temporary[i].guild.channels.find(x => x.id == temporary[i].newID)
         // Channel Found!         
         if(ch.members.size <= 0){

             await ch.delete()
             // Channel has been deleted!
             return temporary.splice(i, 1)
         }
     }
 })

这是基于 Raifyks' answer，但针对 Discord.js v12/v13 进行了更新，并进行了一些改进。

const mainCategory = '604259561536225298';
const mainChannel = '614954752693764119';

// A set that will contain the IDs of the temporary channels created.
/** @type {Set<import('discord.js').Snowflake>} */
const temporaryChannels = new Set();

bot.on('voiceStateUpdate', async (oldVoiceState, newVoiceState) => {
    try {
        const {channelID: oldChannelId, channel: oldChannel} = oldVoiceState;
        const {channelID: newChannelId, guild, member} = newVoiceState;

        // Create the temporary channel
        if (newChannelId === mainChannel) {
            // Create the temporary voice channel.
            // Note that you can set the parent of the channel in the
            // createChannel call, without having to set the parent in a
            // separate request to Discord's API.
            const channel = await guild.channels.create(
                `${member.user.username}'s channel`,
                {type: 'voice', parent: mainCategory}
            );
            // Add the channel id to the array of temporary channel ids.
            temporaryChannels.add(channel.id);
            // Move the member to the new channel.
            await newVoiceState.setChannel(channel);
        }

        // Remove empty temporary channels
        if (
            // Is the channel empty? (thanks to Rakshith B S for pointing this out)
            !oldChannel.members.size &&
            // Did the user come from a temporary channel?
            temporaryChannels.has(oldChannelId) &&
            // Did the user change channels or leave the temporary channel?
            oldChannelId !== newChannelId
        ) {
            // Delete the channel
            await oldChannel.delete();
            // Remove the channel id from the temporary channels set
            temporaryChannels.delete(oldChannelId);
        }
    } catch (error) {
        // Handle any errors
        console.error(error);
    }
});

您可以尝试先定义一个空变量，例如 temp，然后在返回 createChannel() 承诺时为其分配临时通道，如下所示：

 bot.on('voiceStateUpdate', (oldMember, newMember) =>{
        let mainCatagory = '604259561536225298';
        let mainChannel = '614954752693764119';
        let temp;
        if(newMember.voiceChannelID === mainChannel){
            newMember.guild.createChannel(`${newMember.user.username}'s Channel`,'voice')
            .then(temporary => {
                temp = temporary
                temporary.setParent(mainCatagory)
                .then(() => newMember.setVoiceChannel(temporary.id))
            }).catch(err =>{
                console.error(err);
            })
        }
        if(newMember.voiceChannel.members.size === 0){temp.delete()};
    });
