【问题描述】:
我正在制作一个播放音乐的不和谐机器人。目前,嵌入列表工作正常,每次我将歌曲添加到队列时,列表都会自行删除并创建一个新的嵌入队列列表,并使用新歌曲进行更新。但是,当我使用已实现的跳过按钮时(我是编程新手),我无法弄清楚如何使此队列列表自行更新。
现在如何工作的示例:
按按钮跳过歌曲,但如前所述,每次按按钮时如何刷新列表?
const ytdl = require('ytdl-core');
const ytSearch = require('yt-search');
process.setMaxListeners(1000000000000);
const { MessageEmbed } = require('discord.js');
ffmpeg_options = {
'options': '-vn',
"before_options": "-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5"
}
