I wanted to make a music discord bot and I’ve been having trouble with it for a while. and I keep getting an error and I got this code from CodeLyon’s video called “Make Your Own Discord Bot | Music Bot (Play, Skip, Stop Commands)”
I keep getting the same error when I try it:
ReferenceError: PREFIX is not defined
const ytdl = require("ytdl-core");
var servers = {};
client.on('message', message => {
let args = message.content.substring(PREFIX.length).split(" ");
switch (args[0]){
case "play":
const prefix = '!';
function play(connection, message){
var server= servers[message.guild.id];
server.dispatcher = connection.play(ytdl(server.queue[0], {filter: "audioonly"}));
server.queue.shift();
server.dispatcher.on("end", function(){
if(server.queue[0]){
play(connection, message);
}else {
connection.disconnect();
}
});
}
if(!args[1]){
message.channel.send("you need to provide a link");
return;
}
if(!message.member.VoiceChannel){
message.channel.send("you must be in a channel to play the bot");
return;
}
if(!serveres[message.guild.id]) servers[message.guild.id] = {
queue: []
}
var server = servers[message.guild.id];
server.queue.push(args[1]);
if(!message.guild.voice) message.member.VoiceChannel.join().then(function(Connection){
play(connection, message)
})
break;
case 'skip':
var server = servers[message.guild.id];
if(server.dispatcher) server.dispatcher.end();
break;
case 'stop':
var server = servers[message.guild.id];
if(message.guild.voice){
for(var i = server.queue.length -1; i >=0;i--){
server.queue.splice(i, 1);
}
server.dispatcher.end();
console.log('stopped the queue')
}
if(message.guild.connection) message.guild.voice.disconnect();
break;
}
});
Answer
The error you are getting basically tells you that you have not defined the PREFIX variable.
At the top of your code you should add the following constant variable:
const PREFIX = '!';
