Networking Lobby Example Beta Q&A

My computer starts to overheat when running the sample lobby scene in the editor or as a standalone on Mac. My Mac is less than 2 years old, but I don't have a dedicated graphics card. Could this be why, due to the sample lobby using a taxing UI?

 

It's more likely you have a problem with the cooling system in your PC, blocked heat sink or failed fan possibly.

 

Nope, nothing wrong with this MacBook Pro.

 

Have you run the profiler of this?

We're not seeing anything wrong as far as we can tell...

If you can find a glitch, we'd love to know about it.

 

Hi Adam,

Thanks for your response. I just ran it with the profiler, and I'm not sure what to look for, but nothing jumped out at me. As far as the laptop getting hot, I'm 99% sure it's because I don't have discrete graphics.

 

Do you find this to be true with other Unity scenes? Or just the lobby?

If you want, you can file a bug report from you in-editor reporting tool, and it will include a snapshot of your hardware.

 

This is the first time I've seen the laptop heat up with a project running in the editor; it's a project with just the assets from the package. A game like Portal will heat up my laptop, so that's why I think it's a weak graphics hardware thing.

I'll go ahead and do that in case it is of any help.

 

Thanks. Can you get the report number to me, just in case?

 

Hi! I did all that is described in instruction 1-6, but it is working only on local machine. When I try to connect with other users over the web it is not working. What else should I do to make it working?

 

Hello, I have registered my project on https://multiplayer.unity3d.com and use matchmaker as stated in the instruction. But it is not working. Is there any detailed instruction on how to use matchmaker? Maybe I am doing something wrong... I just registered my project and entered project ID.

 

After creating a match, but before starting it, if I go back to the main panel and call StopMatchMaker, StopServer, and StopClient, OnStartLocalPlayer on the lobby player object is automatically called between the calls to StopServer and StopClient. Is this a bug?

 

I use Unity 5.1.1f1. I created new project. Created Cloud id - fe107d36-15a7-4481-8cff-6950ebc1f5fe and entered it in Player settings.
When I hit play, give a game name "A3" and hit Create into "Create Game" section I have got following errors:
Failed to read the ID for the match maker, please set the Cloud Project ID string in the Player Settings (see https://unet.cloud.unity3d.com).

If I am on the project page https://multiplayer.unity3d.com/orgs/dmitry-4430781/projects/a3/unet and refresh page, I got following error: Unable to load project. (400).

 

Upgraded to 5.1.2p3 and installed a fresh copy of this package. When clicking any of the following buttons and then clicking "Back" at the top, the error message below repeats. Thanks for any help.

Buttons: "Create", "Play and Host", "Dedicated Server"

Error message: "host id {0} has been already deleted"

 

Did anybody notice that the color is not being synced from the lobby player to the game scene player in the NetworkStarter example from Unity.

This is the same problem I'm having with my game.

Anybody knows how to solve it?

Thanks

 

Hello UnityGuillaume,

Its the UNET demo written by Unity I just downloaded yesterday from the Unity asset store

https://www.assetstore.unity3d.com/en/#!/content/41836

I have Unity 5.1.2f1, You can see the problem if you run one instance as "Server only" then others as "Client Only", then change the colors while in the lobby, then run the game, the color of the players in the game is always black, not the colors that was selected in the lobby.

Also the color synching dont seem to work too good while in the lobby.

 

Hi UnityGuillaume,

I have downloaded the project, followed the steps
But i could not create game using matchmaking

The matchmaker automatically create the game on localhost and thus i am not able to connect two computers.

Check the Status and Host
For fraction of second it tried to connect to cloude server and then changed automatically to Host

please check the images

 

I am having the same issue!!!

 

I would also like to know how I can fire the "Join" button for the Client joining a server without the UI button. I am having a pretty hard time getting the button to click itself when I fire a command from an EventTrigger, so I was wondering if there is an easier way. I am using Matchmaking, and need to join an existing Match via C# script.

 

I dowloaded and updated version on 5.1.2p but when check my version it still shows old one. Moreover when i check for updates i have the message ”the unity editor is up to date currently installed version is 5.1.1f1.

 

When click on List Servers button from Android device, i am getting below exception

Request error: java.io.FileNotFoundException: https://mm.unet.unity3d.com/json/reply/ListMatchRequest

Raw response:

NullReferenceException: Object reference not set to an instance of an object

Anybody any idea???

 

Hi UnityGuillaume,

thanks for your reply.
will wait for your ans on android. I had a very hard last week, tried all kind of solutions on forum, but no luck with the matmaking of android and window machine build

Also i want to know if it is possible to assign custom hostname (just like room name in case of matchmaker) with Play and Host game?

i mean i can host on windows machine and connect android build using windows machine's ipadress, but is it possible to assign custom name to ipaddress (to hide ipaddress).

thanks in advance

 

Hi, when i use matchmaker in my pc i can create matchs and see them, but when i try to create/list servers in other pc i get some errors:



why does this happens? what can i do? many thanks!

EDIT1: and when a send to a friend, he creates but i can't see any match

 

in game play mode, jump button not working on android

 

In this asset https://www.assetstore.unity3d.com/en/#!/content/41836

in game play it can be disconnected one people? now if touch back button game will end
for example, I want disconnect one people he will lose all coin
thank you. sorry for my english skill is bad.

 

Hi @UnityGuillaume! Any plan you can share on releasing a post-beta version?

 

HI
I just downloaded the multiplayer version of the Tanks Tutorial. In it I tried the completed assets game by building it and running it on different computers. It works and looks amazing, but it lags. Is that normal? One player cannot see the screen of the game until the 3rd round, but his tank moves properly and aligns perfectly with the buttons.

Also I was wondering if anyone could post an explanation of the Networking scripts used in the Lobby Scene as I want to edit my UI and game to have different events.

Thx in advance!

 

Hi. Is there any video tutorial for the unity networking stuff?

 

There is this thread and there is the Multiplayer Tanks! Project as well. We have more items incoming.

 

U need to get the unity multiplayer cloud id.
In unity 5.2 u will see cloud icon on top in player settings click on that and in earlier versions u have to paste the cloud id in player settings only.

 

Hi! It is possibile, using the lobby, to join a game already in progress? Documentation says "Option to prevent players from joining a game in progress", but I don't understand if I can bypass it. Thanks!

 

This is great! Does this support LAN games (that don't use the relay server, just exists locally)? Also, will this eventually still become part of standard assets (as mentioned in the docs)?

 

This is all great news. I didn't know that the "Direct Connection" section truly meant that the relay was not used, just thought it was a straight alternative to the match maker, everything else being the same.

I currently take your beta asset, clear out the game and the extra stuff not needed for the lobby scene, and add that to my game. Will the standard asset be more like something we can drop in our game or will it essentially be a full project as it is now?

 

I am really stuck , I can't figure out what's the problem , I am trying to lobby the game on android platform , I tried between my android phone and computer but the problem am keeping getting stuck on the "Connect..." UI wen joining a match from the server list , or when I try to join 127.0.0.1 after making play and host room , I get "Connect..." UI then I get error :

UNet Client Disconnect Error: Timeout
UnityEngine.Networking.NetworkIdentity:UNetStaticUpdate()

and sometimes I get this log:

Multiple NetworkManagers detected in the scene. Only one NetworkManager can exist at a time. The duplicate NetworkManager will not be used.
UnityEngine.Networking.NetworkManager:Awake()

**** I kinda solved it by changing the localhost in the lobby prefab

 

Hi UnityGuillaume,

I'm currently working on my own Lobby-System, inspired by your example.
Everything seems to work fine, but when I call "SendReturnToLobby()" from playScene in order to get back to lobbyScene, I get the following error:

SetClientOwner m_ClientAuthorityOwner already set!

StackTrace:
UnityEngine.Networking.NetworkLobbyManager:SendReturnToLobby()
MPITNumberController:<ShowTimeIsUpDialog>m__5() (at Assets/Scripts/Controller/InformationTheory/MPITNumberController.cs:313)
UnityEngine.EventSystems.EventSystem:Update()

Besides this error, no problems occur.
It doesn't seem to have any effect on the functionality of my lobby either.
The clients are correctly redirected to the lobbyScene and can start the next match.
I'm just curious why I get this, or how I can avoid it.

Cheers,
phineliner

After some steps working with the NetworkLobby, I think there might be an issue with using a minimum player count of 1, respectively with joining ongoing games.

For my game, I have no minimum player count. It is possible to start a game with just a single player. Other players may join an ongoing game at any later point. Thus, I'm using a minimum player count of 1 set in the NetworkLobby. Unfortunately, however, it does not work for other players to join an ongoing game with the NetworkLobby example. When I start a game with one player, as soon as another player tries to join the ongoing game, there are some errors thrown on the server, starting with 'Attempt to send to not connected connection {1}'. Please have a look at the attached screenshot for the whole log.

You can easily reproduce this issue with the clean and unmodified NetworkLobby asset (v1.2) by just setting Minimum Players of the Network Lobby to 1, go Play and Host, set ready and start the actual game, and then try to join with another game instance.

Please have a look. Thanks.

 

How can i remove my playerlist

 

In my game when I run with more than one player I encounter some bugs. Anyone controls everyone. You can't look in the Y-Axis in your camera. How do I fix this?

 

Hi, after I host a game and have a client connect, some of my objects (my game control object and pooler) are being destroyed despite calling DontDestroyOnLoad when they awake. This only happens on the client. The objects are not in children of any other objects. Anyone else having this? I'm using Lobby 1.2 with Unity 5.2.3. Thanks.
