description: 'initiates music methods of the bot',
execute(msg, args){
var servers = {};
function play(connection, msg){
var server = servers[msg.guild.id];
server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: "audioonly"}));
server.queue.shift();
server.dispatcher.on("end", function(){
if(server.queue[0]){
play(connection, msg);
}else{
connection.disconnect();
}
});
}
if(!args[1]) return msg.channel.send("you need to provide a link");
if(!msg.member.voiceChannel) return msg.channel.send("You must be in a voice channel to use this feature");
if(!servers[msg.guild.id]) servers[msg.guild.id] = {
queue: []
}
var server = servers[msg.guild.id];
server.queue.push(args[1]);
if(!msg.guild.voiceConnection) msg.member.voiceChannel.join().then(function(connection){
play(connection, msg);
})
}
}I have no idea what the issue is. I am using heroku to deploy if that matters at all.
