显示用户连接到语音通道？

Question

I want to know is it possible to know if any member is connected to a any voice channel in discord.js v12.2.0. Please let me know if you have any clues on it.

Answer 1

Use VoiceChannel.members

const vc = <message>.guild.channels.cache.get('VC Id')
const members = vc.members //COLLECTION

To check if a member is in vc, use GuildMember.voice

const vc = <member>.voice.channel //VOICE CHANNEL
//if you want, you can check the vc name, id, etc with vc.name, vc.id, etc

EDIT
Here is an example for what you said in the comments

//MAKE SURE IT IS ASYNC CALLBACK
await client.guilds.fetch();
const VCs = [];
client.guilds.cache.forEach(async guild => {
await guild.channels.fetch();
let VCs = guild.channels.cache.filter(c => c.type === 'voice');
VCs.forEach(vc => {
if(vc.members) {
VCs.push(vc)
}
})
})

I hope this is what you wanted ( VCs is an array with all VCs with members)
