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.

Heh nowadays making multiplayer games is easier than ever so that's great timing!

@@CodeMonkeyUnity does a multiplayer game cost , or how much you need to spend to create a multiplayer game by your self?

[@phlips8254]

@@ergicela4420 The lobby system in this tutorial is done with the base Unity system and is free as long as you don't use too much data (unless you have a lot of players this won't happen), then the hosting of the server is done by the player that is the host of the lobby. Because of this you don't need to run your own servers and the entire system is free to use. So no you don't have to pay to add multiplayer

[@sir.niklas2090]

Honestly Multiplayer is still difficult get some practice in, not years but just understanding.

[@zanuka9765]

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 UnityServices.InitializeAsync(options); //

[@CodeMonkeyUnity]

Not sure what timestamp you're referring to, what two different variables? You mean lobbyName and maxPlayers? It's to avoid using magic numbers kzbin.infoCQ5xHgRZGQo Sure, you can use a coroutine instead of a float timer. Personally I prefer float timers because I dislike the cumbersome structure that coroutines force you to use. You need a MonoBehaviour, need IEnumerator, need yield return, need StartCoroutine(); whereas with a float timer you just have a simple number. But that's just personal preference.

[@kpr2]

@@CodeMonkeyUnity Apologies. By the time I got to the end of the video it more or less made sense & I edited the comment, haha 😆. I was referring in particular to the lobby, hostLobby, and then joinedLobby variables. For the sake of "safety", I followed most of your instructions, though I did swap out the Update timers for coroutines as I'm just used to them. My head's swimming a bit as the last 20 minutes of the video really ramped things up a notch, but I was able to keep up well enough & everything looks good! I'll certainly be grabbing your project files to check for reference as I'd like to see how you implemented the UI functionality, particularly for kicking players & such.

[@somegamer7958]

Couple of minor changes I'd make - using multiple lobby variables is a bit confusing. You really just need one. Switching them back and forth isn't necessary since one client is going to be be a part of one lobby at a time. Also, logging into a lobby via code. I think for a tutorial it makes more sense to log in by lobby Id, because that's a value you can actually get. Only the host of the lobby gets access to the lobby's code.

[@CodeMonkeyUnity]

What do you mean multiple Lobby variables? There's just one member variable which is set whenever a function changes it, you need to do that since the variable won't update by itself. If you want to see it as part of a complete game I used this in my complete course kzbin.info/www/bejne/bZjPdKZ8bsupadU

[@jean-michel.houbre]

Good afternoon! In anticipation of the looby part of the "Learn Unity Multiplayer" video, I just finished the "Making a MULTIPLAYER Game? Join your Players with LOBBY!" video, a very clear and very informative video as usual. Thank you for the passage concerning the prices, I had already read it, but it is reassuring for a non-English speaker to have an additional interpretation. I have many qustions : a) when all players leave the lobby, we get a bunch of errors in the console: - [Lobby]: LobbyNotFound, (16001). Message: lobby not found - HttpException`1: HTTP/1.1 404 Not Found How to manage them? b) I didn't understand why we have 2 lobby variables (hostLobby and joinedLobby). We only have one lobby, don't we? c) At 47:20, you have a using Unity.VisualScripting clause. This happened to me from time to time, and I got into the habit of uninstalling several packages installed by default by Unity: VisualScripting, Visual Studio Code Editor and JetBrains Rider Editor. I have the impression (at 90%) that Visual Studio offers me fewer functions for autocompletion. I would like it to be automatic, but I admit that my first attempts were not convincing :) Thank you very much for this video !

[@jean-michel.houbre]

Connection with Codemonkey lost ... I hope you're doing well.

[@davidwusoftdev]

For (a) you would need to set the lobby to null in the catch section of the code, so that the Update function stops the heartbeat to an already deleted lobby. For (b) you can probably modify the code to only use joinedLobby. I'm guessing CM uses two different variable names for teaching clarity. I have no idea about (c). If you don't need that reference in your code, just delete the line. You should keep Visual Studio Code Editor package if you're using the VS IDE to write your code though, I think it's needed for proper integration. Good luck!

I'm getting a bug when I run my game in a standalone build that causes the player to never leave the lobby if I close the game while still inside it. I can force leave the lobby, but closing the game seems to leave the lobby open forever. Any experience with this bug or an idea on how to fix it? UPDATE: I think calling delete lobby or remove player from lobby from OnApplicationQuit works, but only if you don't do it asynchronously (so no async/await in the call).

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

[@mjkkaya6056]

How do you achieve to show so many features in a single video? This is awesome!

[@Maskedmous]

Lobby services with 10 gb is neat. Free authentication, remote config and cloud storage. Relay services however can become quite costly**. let's say your game is $15. 30% goes to steam, $5 for simplicity. Then you have your own take of $5. The rest $5 goes back into the game. which means ($5 / $0.16) / 12 ≈ 2,6 years. After that you're paying it yourself to support your own games networking. By then you require another monetization feature just to keep the game running. Or revert back to Direct IP which is troublesome for most players to set up. Most of them don't even know how to access a router / modem let alone configure it for some game. I'm ignoring bandwidth here, but that also is quite costly when you go above 150 gb of data. Multiplayer is great, just not the costs that come with them. ** Sure there are caveats and this calculation is a worst case scenario 100% playtime. It still feels expensive. Perhaps my view on it is too extreme.

[@CodeMonkeyUnity]

Your math is a bit confusing, you're assuming every single player will be online at the exact same time playing 24/7 for 2.6 years, that is an extreme scenario that doesn't really ever happen. Remember it's Concurrent users, not just Users. As an example, my own game Battle Royale Tycoon, which was a decently successful release (for an indie dev) only had a single month above 50 CCUs with 75. So if the game was multiplayer it would have costed me $4 while it sold over $100,000 So to me the math seems really good. If you have thousands of CCUs then your game is a mega-hit which sold hundreds of thousands of copies and those players will not play 24/7 for 2 years.

Thank you for the video!! I have realized one thing that happens sometimes. It might have to do with the fact that most of the code here are async code that when I stop playmode (from testing), time and after the scene changes when exiting playmode - (aka is different to what it was before starting play mode)... usually this is fine as reloading the same scene by clicking in the scene from the project in the editor restores it to what it was before... But I was wondering if this could happen for a build as well? because I had a few times where the camera was getting disabled for no particular reason when exiting playmode and this would be really bad if it happens in a build and remains that way...

But they work perfectly fine, so if you like them then by all means use them

The Lobby deletes itself and doesn't migrate host after the host "unexpectedly" disconnects (simply turning off unity play) instead of just leaving the room. Is there a way around this?

[@jihadrouani5525]

Massive thanks for this multiplayer series, and super excited for the upcoming one, I hope you make more and more videos or even courses on multiplayer, DOTS, ECS... I'm sure they'll be very valuable. And I hope I can support with more sizeable donations in the future, being an indie dev making games with nothing released yet is kinda hard on my ressources 🥲

[@CodeMonkeyUnity]

Thanks for the super thanks! Best of luck in your game dev journey!

[@nileshsharma9009]

Great Video! just want to know if we can customize the lobby code or not.. like if i want it to be for 5 characters only, something like that was present in photon i think!

[@CodeMonkeyUnity]

No I don't think that's possible, it's auto-generated on Unity's side

[@arvydazo4203]

when lobby host left the lobby, for example wifi disapears or game crashes, lobby disapears after 30s from the list, but players in lobby stays endefinetely with no warning that lobby no more exist. is there a way to change lobby owner when original owner is offline?

[@stefancc83]

do you have any video showing how to transfer data between host and guest and both of them getting notified on events? Usecase: guest changes its data and host gets notified about changes and viceversa.

Can u Please Explain I can See QuickJoin Method On Lobbies Class And LobbyServices class as well whats Difference both?

[@md3d519]

im curious on how you made the chat and commands , a tutorial on that would be appreciated

[@Overdrink7]

It's a unity asset If I remember well. And he probably explained it in a previous video

[@Overdrink7]

See the previous video of the playlist

[@romain4088]

is it possible to spawn the players in the lobby in the same game with the character they picked using unity netcode?

[@CodeMonkeyUnity]

When you join the lobby you can initiate the NGO connection right away, that's what I'm doing in my multiplayer game, video coming out next Monday

[@k3bolkb641]

Photon or Netcode what should I use?

[@MarekNijaki]

Very very good video

[@TheKr0ckeR]

Can we test this without relay on across computers from different places? Do we need relay setup to get in a lobby without locally?

[@CodeMonkeyUnity]

Lobby does not need Relay, Lobby is just an HTTP connection so there are no issues with firewalls or NAT. You only need Relay to create the NGO connection

[@Somiaz]

How do I even get the UI set up? It seems this was also a crucial part that was missed? Especially since so many changed were made from during the tutorial. It would have been nice to see how to set everything up fully even with basic Unity UI stuff.

[@CodeMonkeyUnity]

In any way you want, every game will have a different UI. If you want to see that step by step I did pretty much exactly the same thing in my free multiplayer course kzbin.info/www/bejne/bZjPdKZ8bsupadU

[@ananths1122]

This was very useful. (Question) I un-commented "HandleRefreshLobbyList( )" , but 5 seconds was too soon for it, says "Too many requests", What other time interval do you suggest for lobby refresh ?

[@CodeMonkeyUnity]

The docs mention the rate limits for each function

[@netanelkomm5636]

Hey code monkey, i've got a problem related to scene loading: when the host decides to start the game, StartGame is called, updating the KEY_START_GAME just like in your relay tutorial. Then it loads the game scene. Upon the completion of the game scene loading - the function SceneManager_OnLoadEventCompleted is called (custom function i made) - to spawn the connected players. The problem - it only spawns the host. It happens because the clients join after the scene was loaded - maybe because the update polling isn't happening immediately, and also the fact that joining a relay takes time. Is there any way to solve this? Maybe wait for all the lobby clients to join or something? Because what I'm doing now is just waiting 5 seconds which is obviously not ideal....

[@CodeMonkeyUnity]

How did you listen to that function? Some load events are only triggered on the host, there is one for when the host finishes loading, others when clients finish loading, and I think there's one when all clients have finished loading, you need to hook onto that one and spawn all clients

[@netanelkomm5636]

@@CodeMonkeyUnity Okay, i'd send you the link where you can see the functions, but it seems that you disabled links in your comments.... So i'll write it manually. Here's the class I made for spawning the players, I put it in the lobby scene: As you can see, Im using OnLoadEventCompleted. Its important to mention that this runs on the host. public class SpawnPlayers : NetworkBehaviour { [SerializeField] private Transform playerPrefab; // Start is called before the first frame update public override void OnNetworkSpawn() { if (IsServer) { NetworkManager.Singleton.SceneManager.OnLoadEventCompleted += SceneManager_OnLoadEventCompleted; } } private void SceneManager_OnLoadEventCompleted(string sceneName, UnityEngine.SceneManagement.LoadSceneMode loadSceneMode, List clientsCompleted, List clientsTimedOut) { Debug.Log("Spawning players..."); foreach (ulong clientId in NetworkManager.Singleton.ConnectedClientsIds) { Debug.Log(clientId); Transform playerTransform = Instantiate(playerPrefab); playerTransform.GetComponent().SpawnAsPlayerObject(clientId, true); } } }

[@netanelkomm5636]

@@CodeMonkeyUnity I mean, the problem is not with the loading. Its the fact that the event is invoked when all clients finish loading the scene. But when LoadScene is called, the clients haven't connected yet - since they haven't polled the lobby update yet - so it's only taking the host (which is the only connected client), into account.

[@ANlevant]

this is very interesting, but I came looking for a way to connect my lobby with my Multiplayer game which uses Netcode for Game Objects

[@Flem100DK]

Shouldn't you return Task instead of void when it's not an event?

[@CodeMonkeyUnity]

It depends if you want to return any value or not. If you want to return anything at all then yes you need to return Task But if you don't want to return anything then void works fine

[@anujsaini0271]

I have some doubts, how host is migrated if host has quit the game suddenly? How Host is migarted without using migrateLobbyHost() by host as host lobby will be null hence no pingheartBeat would be called?
