DarkRift Networking 2

Is it possible to assign a value to the onConnected() parameter "object sender" from the client

 

It is not I'm afraid, the 'sender' parameter is a .NET standard practice and always contains the object that triggered the event. You can always send a message once the client has connected containing whatever you need!

 

Hello,

Are the Inter-server Communication and Area of Interest System (Helper) features available in Pro yet? On the website they say coming in 2019 and 2020 respectively, but I don't see them as confirmed anywhere on the store page or documentation.

 

hey sorry for the long delay in reply, by default VS 2017 wants to debug the client, switching to Server.Console works for a successful build. Thanks Jamster now i can get back to making a MMO.
Still got the same .NET 2.1 error when trying to compile, debugging right in VS works just fine.

 

DarkRift 2.7.0 is now available on the website!

Hi!

My usecase is "server maintenance", that client is on autoconnect and server is down. Client is starting up and of course autoconnects. It can not, because there is no server. But later on I will start the server too. Client is unable to connect AND stays in "connecting" state.

If I want to manually ".Connect(...)" the client .NET socketexception is thrown.

Is there a way to make client retry connecting or just forget it's connecting state or get a proper timeout or... something?

Thank you for your help:
Péter

 

Hi Péter!

Does the issue you're seeing look like this bug?

I don't really know a good workaround for the moment, if you can catch the exception and recreate the UnityClient that might be the best bet until it's fixed.

Jamie

 

Hi Jamie!

Thank you for the support!
Yes and the exception message is the same as well.

Workaround I tried and failed so far: disabling and enabling the component (does nothing, because the UnityClient is created in the Awake), repeating the Start method (leads to the Exception), disabling the whole object and enabling it only after the server is awake (works, but kills purpose of detecting maintenance), maybe some others but forgot them.

What I will try then: re-creating the whole component on GameObject.

Thanks:
Péter

 

This will do the trick as "workaround" for previous:

Code (CSharp):

1.    
2. //[SerializeField]  UnityClient kliens;
3. //...
4.  
5. if (kliens.ConnectionState != ConnectionState.Connected)
6.     {
7.       IPAddress ip = kliens.Address;
8.       ushort port = kliens.Port;
9.       Destroy(kliens.gameObject.GetComponent<UnityClient>());
10.       kliens = kliens.gameObject.AddComponent<UnityClient>();
11.       kliens.Address = ip;
12.       kliens.Port = port;
13.     }

Of course it is not a full solution, it copies only the IP and the port.

hi
quick question. I use playmaker to build my games, how easy/hard would it be to use darkrift 2 with playmaker? i plan on making a 'battle royale' game along the lines of fortnite/PUBG/warzone etc with 100 players per game (room).

thanks

 

Will DarkRift 2 support consoles out of the box ? (XBox One & X, PS4 & 5, Switch)

According to the .pdf from this Unity Blog post https://blogs.unity3d.com/2020/09/08/choosing-the-right-netcode-for-your-game/ , they found no one who successfully passed any console certification.

 

Hi this library can be deployed on ps4 and nintendo switch ?

 

Apologies for the late reply to everyone, I haven't been receiving notifications for some reason!

I'm afraid I haven't used Playmaker before so I can't really comment. DR is very programmatic so if it Playmaker allows you to make arbitrary C# calls then I suspect it will work, though I don't know how easy that will be!

I know some people in the community build for consoles but I don't know which consoles they are nor how easy they are to build for. DarkRift isn't tested on consoles so I won't make any claims for it to work on them! The best advice I can suggest is to just try it with the free version!

 

DarkRift 2.7.0 unity server outputs this error " HttpListenerException: Listener closed" when shutdown. any fix?

 

I think this is a bug that will be fixed in the next version. If you're not using the HTTP health check or the Prometheus metrics (pro) you could disable the associated plugins (HttpHealthcheck/PrometheusEndpoint) to stop the errors ocurring.

 

I have an error.Occasionally, the client will not receive a response from the server. but that client still sends the message and the server still receives them.

 

Strange. The only way I can imagine that ocurring is if the update loop in UnityClient has stopped. Have you modified any of the DarkRift files? Are there any disconnection logs output either end?

 

DarkRift 2.8.0 is now available on the website!
DarkRift 2.8.0 being the beta of server clustering (formerly referred to as inter-server communication) as well as a few bug fixes!

Check out the docs to get started with the server clustering beta here!

If I authenticate the user via php and then I connect them to the Dark Rift server how would php pass the userID to Dark Rift so I can access the database based on their ID through Dark Rift?

Obviously I shouldn't let the client pass the userID to the server since that would be a security risk. It should all be done on the server side. Is there a recommended way for php to send a variable to Dark Rift?

Which part of the documentation should I be looking at?

 

DarkRift 2.8.0 is now available on the Asset Store!

 

Usually the best way is to return the user a token of some form, such as a JWT (JSON Web Token) or some randomly generated short-lived token. That token can then be handed to the DarkRift serverto prove the client is who they say they are.

JWTs are signed to be from your server so the client can't modify them in a way accepted by the server, short lived tokens are just randomly generated so can't be spoofed! There are plenty of other ways to do it as well, personally though I'd lookat a JWT I think as I've used them before!

 

Is there a way for php to just send the variable data directly to Dark Rift?

EDIT: Actually I think I understand. I'll go try it out and report back later. Thank you!

 

DarkRift 2.8.1 is now available on the website!

12.     }

Client code:

Code (CSharp):

1. public UnityClient client;
2.     public void Awake()
3.     {
4.         // User inputs IP, code checks if IP is valid, then IP gets saved to PlayerPrefs. Then, load client scene.
5.         client.Address = System.Net.IPAddress.Parse(UnityEngine.PlayerPrefs.GetString("IP"));
6.         UnityEngine.PlayerPrefs.DeleteAll();
7.     }
8.  

Thanks in advance!

 

Sure can!

Where are you hosting your server and what type of IP address are you trying to connect with (Public? LAN? Localhost?)

If the server is just hosted on a player's machine they will need to port forward the TCP and UDP port on their router.

 

I want the client to communicate with a local server on the same network (LAN) and the user can manually type the server IP. This is currently not working.

Also, when I added a Debug.Log() function on the Start() function of one of your scripts (i forgot which), it does not log anything on the console, even though it was the first function in Start(). I am sure I put the script on an active GameObject.

 

OK, in that case you want to be using the internal IP address (i.e. the one found from on ipconfig) rather than the public IP
(e.g. the one external websites tell you). Are you using that?

 

Yes. I have been using it. I have a script on the server to set a Text GameObject to show the local IP.
(By the way, the server and the client uses the same Unity project, but different scenes. If this setup does not work, let me know )

Also, does DarkRift Networking 2 support multiplatform (Android = server, PC = client)? Thanks in advance!

 

DarkRift 2.9.0 is now available on the website!

This mainly contains bug fixes and quality of life improvements for server clustering but also contains a few new features. You can now use a DNS name in the UnityClient component and can use environment variables in configuration!

The update is already available on the website here, or through the DarkRift CLI tool and will be available on the asset store in the coming few days!
https://www.darkriftnetworking.com/DarkRift2/Releases/Free/2.9.0.unitypackage
https://www.darkriftnetworking.com/....0.unitypackage?invoice=<your invoice number>

 

Building the server and clinet from the same project is fine, but you should be aware you can end up with server only stuff in your client builds and vice versa, you usually want to have some conditional compilation etc. to separate them!

DR2 is multiplatform client wise yes, but the server is only designed to run on a PC/server, running servers on android comes with a whole host of issues even if DR does techncically run on it.

 

DarkRift 2.9.0 is now available on the Asset Store!

 

Looking at this on the Asset store, but had a few questions.

Is this basically a solution to build our own servers without having to use other "Services" and buy the ccus? Most of the ones I have found are just "wrappers" of "templates" if you will for Pun, etc etc. Looking for a simple, no service provider needed solution. I dont plan on using this for gaming over the web as much as I do over LAN networks.

Ive made basic servers for handling very simple data, hoping this is similar except very well formed and easy to implement?

 

Hi!

Yes, DarkRift is a standalone application that you host (usually on a VPS but over LAN is also fine) rather than a service such as those Photon provide. It also has no CCU limits on it, once you download it you can connect as many people to as many servers as you like with it.

DarkRift is a low level solution so it's quite different to use compared to Photon and others, I always recommend just downloading the free version and having a play - that's the best way to know if it's for you!

Can you send unordered udp messages?

 

Yes, use DarkRift's 'unreliable' send mode

 

I am trying to send a message to a Darkrift server with a Python WebSocket client. However, I am getting an error on the server side. Is there any way to send the message correctly from Python?

The error message is as follows

Code (CSharp):

1. [Info]    ClientManager         New client [0] connected [150.249.XXX.XXX:61314].
2. 2020/12/28 15:50:25|Error|<>c__DisplayClass71_0.<receiveRequest>b__0:0|Operation is not supported on this platform.
3. [Info]    ClientManager         Client [0] disconnected.

 

DarkRift doesn't support Python clients so I presume you're writing your own here with the source as reference?

And I'm guessing you're using one of the websocket listeners available on GitHub? This looks more like an exception from inside the websocket listener so it might be better to reach out to the author of the library your using for help. I'm not sure that exception is because your connecting via Python, but more that the platform your server is running on isn't supported by the listener you're using.

 

I'm using Dark RIft 2.9.0, when having other clients we all seem to disconnect with the error "Success"
Disconnected from server, error: Success
I don't use Disconnect in any areas of my code, what could be possibly going wrong?

Code (CSharp):

1. Disconnected from server, error: Success
2. UnityEngine.Debug:Log(Object)
3. DarkRift.Client.Unity.UnityClient:Client_Disconnected(Object, DisconnectedEventArgs) (at Assets/DarkRift/DarkRift/Plugins/Client/UnityClient.cs:524)
4. DarkRift.Client.DarkRiftClient:DisconnectedHandler(SocketError, Exception)
5. DarkRift.Client.NetworkClientConnection:HandleDisconnection(SocketError)
6. DarkRift.Client.BichannelClientConnection:Disconnect(SocketError)
7. DarkRift.Client.BichannelClientConnection:HandleDisconnectionDuringHeaderReceive(SocketAsyncEventArgs)
8. DarkRift.Client.BichannelClientConnection:ReceiveHeaderAndBody(SocketAsyncEventArgs)
9. DarkRift.Client.BichannelClientConnection:AsyncReceiveHeaderCompleted(Object, SocketAsyncEventArgs)
10. System.Threading._ThreadPoolWaitCallback:PerformWaitCallback()
11.  

 

Have a look at the log file in the server (or in Unity you could set the UnityConsoleWriter to output trace logs as that can be easier) for any more information. DR will disconnect clients under certain conditions if it thinks they're being malicious but will always output at trace level when it does so!

 

Hey!
I'm looking for a networking solution and found your Dark Rift which has great reviews.
Before buying (even if I don't immediately need the Pro version, I still want to support great work!), I have some questions (I'm a total beginner in networking and yeah, my project may be ambitious but we all need a goal right?):
1) Would it be suitable for a turn based MMORPG? I see most people using DarkRift for FPS/Matchmaking games or online multiplayers but limited to a few players.
2) What advantage does DarkRift provide over - say Mirror or SpatialOS or PlayFab?

Thank you for your time!
Kind regards

 

You can definitely build an MMORPG with DarkRift, but remember it's a big project with whatever networking system you use! A turn based game is singificantly easier than FPS' etc though!

The key difference for DR is that it's a lot lower level than those. That means you won't be as restricted by DR but you will occasionally have to do more work with DR than in other frameworks.

In the end, I always recommend just downloading the free version and trying it. If you like it, great! If you, don't then you've not lost anything

 

Hi,I found only reliable and unreliable mode. Does DR2 has reliable udp inside it? Thanks for your attention.

 

DR2 uses TCP for reliable traffic by default but you can use a thrid party network listener to make DarkRift's reliable channel use Reliable UDP such as this ENET listener!

 

Thanks Jamster for quickly response. I wonder why DR2 doesn't officially support RUDP for best speed.Is this on roadmap?
