Unity Room Server

Chad Franklin

Hello, I am new to Braincloud and haven't been able to find any docs or examples about room servers in Unity. My game servers are Unity instances and I would like to know what steps I need to take for the room servers to interact with Braincloud. For example, how do I notify Braincloud that my server is ready for player connections with SysRoomReady once the container has started up? Is there an example of this that I am missing? The Unity examples on GitHub only use relay, not room server.

Also, just as a separate question as I am new to DockerHub, I assume my repo needs to be public to be accessible by Braincloud. Are there any security ramifications of that?

Thank you.

Hi Chad,

First, a reminder that Room Servers are still in Beta. It is fully working, but some Libs+Examples are missing.

We do not have a custom server example for Unity yet. Only for relay servers. It is however planned. I would like to have more details on your setup. Your dedicated server is an instance of Unity you said. As a Linux, console-only application? What Network API does it use? I thought Unity killed UNET. Is your dedicated server just a .NET application then?
To notify brainCloud that your server is ready, you have to use the S2S library which we do not have a C# implementation currently, but it is planned. You can still do the calls yourself with any HTTP library. This is also how you will request the Lobby from brainCloud for your room server. You can look at our other libraries implement S2S calls for details: https://github.com/getbraincloud?utf8=✓&q=s2s&type=&language=
Your docker repo does not have to be public. I am currently researching for you how to make this work. If I recall we have a brainCloud docker user you have to allow on your repository. I will come back to you on this.

Another very useful example is our Web(Javascript) WarStone example: https://github.com/getbraincloud/examples-javascript/blob/master/warstone/readme.md

Hi Again,

From docker hud, you need to give read access to this user: braincloudhost

@David-St-Louis-0 Hi David, thanks for your response. I will check out the docker setup when I get back to my desktop. My dedicated server is a Unity instance running the DarkRift2 networking library (https://darkriftnetworking.com/DarkRift2). I build it as a headless Linux build to run inside a container. I previously was running on google compute engine but had trouble setting up Kubernetes and Agones. I just yesterday found Braincloud and decided to give it a shot.

I took a look at the links you sent and I'll have a go at setting up an http client in C#. I won't be ready to deploy anytime soon, so the beta room servers should be alright. I look forward to working with Braincloud. Thanks for the help.

Hi,

So the C# S2S library is planned here for very soon. You might not have to build one yourself. But you can do the calls directly with HTTP anyway meanwhile and upgrade to our S2S once we release it. I'll note this thread and let you know once we release it.

Chad Franklin

@David-St-Louis-0 Sounds great! Is there any loose estimate you can give for when it might be released? If it is soon enough I can just wait for it to come out so i only have to write the code once.

I don't have estimates for it, sorry. But it's at the top of our TODO list.

Hey Chad,

Stay tuned - we'll see what we can do. Hopefully can get an alpha of it out in the next 4ish weeks - just have to revector the right resources...

Paul.

Chad Franklin

@David-St-Louis-0 No worries, look forward to using it.

@Paul-Winterhalder Hi Paul, no rush, take however long is necessary. I'll use the time to familiarize myself with the rest of Braincloud. Will be on the lookout for an update though

@David-St-Louis-0 @Paul-Winterhalder Hello again, I hope everyone at Braincloud is alright regarding the current situation. I wanted to check in and see if there was any progress on the C# S2S library. Completely understandable if it is not ready, but I wanted to ask and hear from you guys. Again, hope you are all healthy and look forward to hearing from you.

Hi Chad,

It is being released this week for 4.5
It is already in the develop branch here: https://github.com/getbraincloud/brainclouds2s-csharp/tree/develop

@David-St-Louis-0 Thank you David, I got up and running with a room server in no time. I wanted to let you know your "Custom Multiplayer Server with Unity" tutorial was very helpful. Thanks for the update and the help

@David-St-Louis-0 Hi brainCloud. I am trying to follow this guidance. I'm new to Docker and containers.

"From docker hud, you need to give read access to this user: braincloudhost"
Did you mean dockerhub online web app? I have not found "permissions" on there. Only a Collaborators option, which gives read and write access.

This guidance
http://help.getbraincloud.com/en/articles/3942761-custom-multiplayer-server-with-unity
has a step "2. Install docker daemon"
On the Docker site I found the option to install a Docker Desktop app (for Windows). Is that what you mean?
Or is there really just a daemon to download? I cannot find such a thing by searching the Docker site. Do you have a link?

If I bother with the whole desktop app, is that where I can find the read-only permissions options?

Thanks!

Paul Winterhalder

Hi @Carson-Herrick ,

You set the permissions in Dockerhub - it's the repository we will retrieve your custom image from.

In summary, you need to do the following in Dockerhub:

Create a team, called "brainCloud" probably, that you are going to use to give us access.
Invite our user, braincloudhost to your repo, and place us on that brainCloud Team. (Note - this user still has no permissions in your repo)
Go to the image that you want to share, then the permissions tab, and give the "brainCloud" team read-only access to that image.

If you do this properly, our braincloudhost user will have read-only access to that image, and nothing else.

I hope that helps!

Paul.

Edit - fixed step 2 with the correct user name, braincloudhost... (I had mistakenly said "bchosting")

Carson Herrick

@Paul-Winterhalder
Thanks.
Note, I think you meant username "braincloudhost", as posted above. ("bchosting" doesn't exist)

Paul Winterhalder

Ah - indeed @Carson-Herrick , you are correct.

Turns out "bchosting" is the name of the group we use in our repo example. braincloudhost is indeed the correct user name.

Apologies for the confusion!

Paul.

For any other small developers out there, just trying to test things out.
Looking through Docker Hub menus and their documentation, it appears you can either create 1 free private repo on your User account (which doesn't allow teams), or you can create a team on an Organization account, which does not offer 1 free private repo. To add private repos to an Organization account, you are looking at a minimum cost of $35/month.

Hi again.
I would like to debug my server locally, in Unity. I have the _S2S stuff all hooked up as described in the walk through.
But then I tried to do the following (actual numbers redacted)

#if UNITY_EDITOR
            var appId = "00000";
            var serverName = "MyServerName";
            var secret = "00000000-0000-0000-0000-000000000000";
            _lobbyId = "00000:myLobbyTypeId:00";
#else
            // Load environment variables passed in by brainCloud to our container
            var appId = Environment.GetEnvironmentVariable("APP_ID");
            var serverName = Environment.GetEnvironmentVariable("SERVER_NAME");
            var secret = Environment.GetEnvironmentVariable("SERVER_SECRET");
            _lobbyId = Environment.GetEnvironmentVariable("LOBBY_ID");
#endif

However, I am getting a perpetual error:
#S2S S2S Failed: {"packetId":1,"messageResponses":[{"reason_code":40613,"status_message":"Processing exception: Unrecognized lobby: 00000:myLobbyTypeId:00","status":400}]}

I even signed up for a Dev+ subscription, just in case that was the problem, per this thread. No luck.

How can I test my server code locally, while still planning for the full-on S2S Docker container deployment?
Thanks
