Discord.js音频Bot播放问题：如何实现检测语音时暂停续播而非从头播放

你当前的代码在用户停止说话时直接销毁了播放实例，因此下次触发播放只能从头加载音频。我们可以通过pause()/resume()方法实现暂停续播，同时监听播放完成事件实现播放完毕后重置的需求。

核心修改点 #

• 修正原代码中dispather的拼写错误（正确拼写为dispatcher，避免运行报错）
• 用户停止说话时不销毁播放实例，仅调用pause()暂停
• 用户恢复说话时，若存在已暂停的播放实例，直接调用resume()续播
• 为播放实例添加finish事件监听，音频自然播放结束后清空实例，下次播放自动从头加载

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

const { token, bypass } = require('./config.json')
const client = new Client()

let previousChannel, connection, dispatcher;
client
.on('ready', () => {
    console.log(`Logged in as ${client.user.tag}`)
})
.on('voiceStateUpdate', async (oldState, newState) => {
    if (newState.id == client.user.id) return
    if (newState.channelID !== null) previousChannel = newState.channelID
    if (newState.channelID == null && !bypass.includes(newState.id) && !!previousChannel) {
        client.channels.cache.get(previousChannel).leave()
        return [previousChannel, dispatcher] = [null, null];
    }

    if (bypass.includes(newState.id)) return
    let channel = client.channels.cache.get(newState.channelID)
    if (!channel) return

    return connection = await channel.join()
})
.on('guildMemberSpeaking', async (member, speaking) => {
    if (!connection) return
    if (bypass.includes(member.user.id)) return

    // 检测到用户开始说话
    if (speaking.bitfield) {
        if (!dispatcher) {
            // 无播放实例，从头创建播放
            dispatcher = connection.play(fs.createReadStream('./audio.mp3'), {
                volume: 1
            })
            // 音频播放完成后清空实例，下次从头播放
            dispatcher.on('finish', () => {
                dispatcher = undefined
            })
        } else if (dispatcher.paused) {
            // 存在暂停的实例，从暂停位置续播
            dispatcher.resume()
        }
    } else {
        // 用户停止说话，暂停播放
        if (dispatcher && !dispatcher.paused) {
            dispatcher.pause()
        }
    }
})
.on('error', console.log)
.on('warn', console.log)
.login(token)

process.on('unhandledRejection', console.log)
