随机播放声音

Question

我正在制作一个Discord机器人，如果我在聊天中输入$join，我想让机器人加入我所在的语音频道，并随机播放一个声音。

case"join":
            message.delete( {timeout: 5000})
            const voiceChannel = message.member.voice.channel

            if(voiceChannel) {
                const connection = await voiceChannel.join()
                const soundFile = fs.readFileSync("./sounds/")
                const randFiles = soundFile[Math.floor(Math.random() * randFiles.length)]
                const dispatcher = connection.play(randFiles)
            } else {
                message.reply("you need to be in a voice channel!").then(message => message.delete( {timeout: 5000}))
            }
            break;

我得到了这个错误。

Answer 1

你有没有读过 文件的 readFileSync()? 唯一的操作系统 readFileSync() 成功地返回一个目录路径的数据是在FreeBSD上。

相反，您要做的是抓取一个目录路径上的文件列表；为此您可以使用 fs.readdirSync():

const soundFile = fs.readdirSync("./sounds/")

Answer 2

fs.readFileSync("./sounds/") 是用来读取文件内容的，你可能在找的是 fs.readdirSync("./sounds/") 它给你一个目录中的文件数组。
