💬 Let's learn how to use Unity Lobby to connect our players together before starting the game.
You can create a new Lobby, make it public or private, then players can find it either through a Lobby browser or by inputting a Lobby code.
You can then define whatever data you want for the Lobby and each Player. Things like Game Mode, Map, Teams or for the Player you can have Selected Character, Loadout, Color, etc.
This is a really easy to use tool that you can add to your Multiplayer games to make it easy for players to find one another.
This also easily integrates with Netcode for Game Objects which I've already covered, and Relay which I will cover in the next video.

Hey anyone confused on async and await well let me explain async will run freely by its self and await will not continue the code until the line its used on has been excecuted if i got something wrong reply since i just researched it and im also confused but i tried my best

[sir.niklas]

Yall, just a tip don't name your script "Lobby" since its a keyword it will give you head aches... :D

[zanuka]

If like me you're a newbie and get the error : "player is already a member of the lobby" while trying to join a lobby from different instances of the game, you have to find a way to differentiate the two players (host and client). One way is to change your authentication method like this :

private async void Start()
{
var options = new InitializationOptions();
options.SetProfile("Player" + Random.Range(0, 1000));

await // Randomize this using the two lines above

Was going to sleep, code monkey's notification came, so I am here ... Postponed sleep for next 52 minutes 😁

As someone who's been working with Unity professionally, you never cease to give really great reference to new services and quick implementation, keep up the hard work!

[ezrahuffman]

Just a note in case some is facing the same issue. If you are using the editor to test (I am using parrellels sync package), the heartbeat might stop when you unfocus the editor window. You can change it in Edit -> Project Settings -> Player -> Resolution and Presentation -> Run In Background. Also the anonymous login will create the same id for both players when logging in by default. You can either clear the session tokens or use different profiles to get around it.

Could you possibly make a tutorial on how to make the UI for the lobby and how to connect it to this? I've followed this tutorial but I'm not quite sure how to do that. The main problem I'm having is I'm not quite sure how to get the names of the players in the lobby, but I see you set it up to do that in your UI.
Regardless, thank you for making these tutorials for us!

I would love some insight in Steam intergration with Unity Multiplayer Networking

[durvesh]

Really appreciate this detailed explanation 👍

[SzaboB]

I just started game developing and it seems like all my ideas that I am excited about are all multiplayer, seems like I timed my start right, thank you for these valuable videos!

[TheAsbjrn]

I have returned to this video approximately 20 times over the last three weeks. It is amazing, giving only what we need and no confusion. I'm actually using what I learn to develop a unity package that incorporates everything here with steam, automatically setting player icons and names and such. Thank you very much for this tutorial, it would have taken me months without

[muerrtee]

i am getting this error while setting up the lobby system

Error CS0029 Cannot implicitly convert type to 'Lobby'

[alec_almartson]

Awesome. 👍🏻😁
You made it look easy... which is the Best a Teacher can do.

I will try it on my future Prototype.

Thank you for making this video. 😄✌🏻

[marcusfanning]

I know this is so dumb, but at 29:15 one of the randomly generated player IDs contains the word "fART" lmao

[lavimahal]

Make a tutorial for netcode using Steamworks p2p also plz.

[linkrider]

My question is, I managed to connect, how can I switch to the game scene and how can I host it in the lobby via netcode? Or is it automatic?

[evanstaylordigital]

Awesome video. I have come back to this several times while prototyping my own lobbies implementation. Would be super helpful if you included chapters!

[LegendaryCombatForce]

How to add search bar so that many players playing the game have option to search the name of any player and add him as a friend instead of lobby
