how to use it in MPP?

[Lamp]

I'd be interested in this as well.
I examined mpp's script (http://www.multiplayerpiano.com/script.js). The interesting part is under "internet science" (ctrl+F)
I downloaded http://www.multiplayerpiano.com/Client.js and tried the following commands:

Client = require('/home/me/Desktop/Client.js');
gClient = new Client("ws://www.multiplayerpiano.com:443");
gClient.setChannel("lobby");
gClient.start();

Each of these were successful until the last one. Server responded with a 401 (Unauthorized).

So we need to authenticate somehow, maybe by sending a cookie or something?

After that I suppose you can just add the event listeners and do what you wish.

So, multiplayer piano server requires authentication, but the OWOP server does not! Using the Client.js from http://ourworldofpixels.com/srcpiano/Client.js, I connected to it from my Nodejs Discord bot and IT WORKED!

See here; when I tried to connect to MPP from OWOP, it refuses:

But connecting to OWOP from MPP... WORKS!

and we can see the rooms:

So while we can't connect to official MPP server until we figure out how to authenticate to it, we can connect to OWOP server and have some fun!
Now to try to do something with it...

and i've just made a DISCORD(.js) TO OWOP BRIDGE!!!! :D

Client = require('Client.js'); // get from http://ourworldofpixels.com/srcpiano/Client.js

gClient = new Client("ws://ourworldofpixels.com:1234");
gClient.setChannel('A room that is bridged to Discord');
gClient.start();

var channel = undefined; // define this as whatever Discord channel you want to bridge to

gClient.on('a', msg => {
  if (msg.p._id !== gClient.getOwnParticipant()._id)
    channel.send("**"+msg.p.name+":** "+msg.a);
});

client.on('message', message => {
  if (message.author !== client.user && message.channel === channel)
    gClient.sendArray([{m:"a", message: message.member.displayName+": "+message.content}]);
});

OMG I DID IT!!!!!!!! I SOLVED IT!!!!!!! :DDDDDDDDDDDD

ok so

We need to send headers to the server on connecting or it'll refuse

The Client.js uses node ws which can take headers in as options.

The connection is made on line 74, so that's where we add our headers.

At first I tried just adding the cookies, but that didn't work

So i added all the headers that the MPP client normally sends, but then it said "invalid server key"

I removed the header "Sec-Websocket-Key"... AND IT WORKED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! AAAAAAAAAA

So one of those headers were needed to get in. It wasn't the cookies. I figured out that all it needs is the "Origin" header! And that's it!!

SO, here is a modified Client.js that'll send that necessary header to enable you to connect to the MPP server from Nodejs!

https://gist.github.com/ledlamp/8c5872c73ee7ca57a1f396fc459f35c0

Then just use the following to connect:

Client = require('MPPclient.js');
gClient = new Client("ws://www.multiplayerpiano.com:443");
gClient.setChannel("MY EPIC NODEJS ROOM");
gClient.start();

And that's it!! Now you can add event listeners and do awesome stuff. You can make chat bots exactly the same way you'd do it in MPP, just use `gClient.on` instead of `MPP.client.on`. And that Discord bridge... now you can use it with MPP (which is where all the fun is!)

const Client = require('MPPclient.js'); // get from https://gist.github.com/ledlamp/8c5872c73ee7ca57a1f396fc459f35c0

const gClient = new Client("ws://www.multiplayerpiano.com:443");
gClient.setChannel("MY EPIC DISCORD-BRIDGED ROOM");

gClient.start();

var channel = undefined; // define this as whatever Discord channel you want to bridge to

// MPP to Discord

gClient.on('a', msg => {
  if (msg.p._id !== gClient.getOwnParticipant()._id)
    channel.send("**"+msg.p.name+":** "+msg.a);
});

// Discord to MPP ('client' is the Discord client)

Can you send me the files on discord? The github page is missing.

[Lamp]

This is no longer necessary; the original script now adds the origin header when used in node.js

You're using an outdated client. the new WS address is wss://www.multiplayerpiano.com:443
