Unity Multiplayer Mirror - Open Source Networking for Unity

I just looked into your bug report. I didn't noticed that you used network simulation - this feature was confirmed to be broken forever. Don't use it, that probably explains the interpolation issues.

 

I have the interpolation issues if I upload the build to my server too.

 

Experimental Version Update: added NetworkTransformChild again.
Note that I don't like that design at all, it should just be NetworkTransform with an optional target property, but for the sake of HLAPI compatibility I wrapped it in a NetworkTransformChild class.

Enjoy!

Does it happen with non rigidbody sync too? Maybe the server is laggy etc.
This is hard to reproduce for me, sorry for the trouble.

 

Yes it also happen with a non-rigidbody sync too. The server is not slow, I've checked. I really gotta get this working soon :/ Do you have a server that you test on?

 

So the default HLAPI NetworkTransform works better than the one in HLAPI Pro for you?

 

No the default one works a lot worse, so I downloaded HLAPI Pro hoping I could get smooth movement on my player.

 

Can you add more than one? as you can add as many NetworkTransformChild components to a NetworkTransform as you want in vanilla UNET.

 

Of course

 

Okay, so it's weird. Got this message again:

DefaultReliable is 0 and 1? wut

Also, Channel setup in NetworkManager:
Channel #0 - Reliable Sequenced
Channel #1 - Unreliable
Channel #2 - All Cost Delivery

 

This isn't saved or detected properly the first time for some reason, someone else had this problem too. Just resave, restart and it will go away at some point.

My guess is that this is related to the UNET bug that we had a while ago where some networkmanager settings weren't saved at all.

 

Wow! This is my post!
So I am a pushed a creator of LLAPI to answer on some critics, which eventually encouraged you to develop the HLAPI Pro.
Incredible!

Your work sounds amazing! Thanks! We are definitely will help to test it.

 

Thanks!

 

Network source is available for 2017.2. Hope to see an updated version soon

 

Been looking into that today but there seems to be a bug:

@larus when I take the 2017.2 code from Bitbucket, build it and copy Output DLLs into 2017.2.0f3 Unity folder on OSX and then open Unity I still get this error:


Even though I did overwrite the Weaver dll exactly like I did with the 2017.1 HLAPI version. Am I missing something?

 

Yeah, I had same error with current version of HLAPI Pro and 2017.2. I guess they've changed something in UnityEditor lib;

 

So...here's a weird question. The following evaluates to null:

Code (CSharp):

1. var leavingPlayer = connectedPlayers.Find( x => x.playerNumber == msg.ReadMessage<IntegerMessage>().value );

but change it a little and it's fine

Code (CSharp):

1. int val = msg.ReadMessage<IntegerMessage>().value;
2. var leavingPlayer = connectedPlayers.Find( x => x.playerNumber == val );

Is this a bug in the behaviour of how NetworkMessage is deserialized or something...?

 

You might be reading message twice. Since it's not caching anywhere.

Also, please don't hijack this thread. I kinda like it

 

@vis2k

I am using 2 projects, one for the client, the other for the server...

After replacing my unity files with your solution i tried to build a client of the client project but i could not proceed due to the following errors :

Starting & Connecting both projects worked without problem.

Using v2017.1.0f3

 

Sorry, wasn't trying to hijack the thread, just trying to figure out if it's an HLAPI Pro bug, or a Unity bug, or a C# bug...I'm not terribly familiar with Lambdas so it could be that.

 

I am not sure if I understand you. You said both projects worked but they don't work?

 

Progress: tried to build HLAPI 2017.2 with the DLL files from my Unity folder, still getting:


Anyone managed to build the fresh HLAPI project and use it in 2017.2?

@larus @aabramychev I know you guys are busy, but could you please test the Bitbucket HLAPI source again?

And any words on HLAPI's future in general?

 

The project works as should during play mode... but when i try to build the client i am getting all those errors...

 

Are you guys saying that even 2017.2 default HLAPI builds doesn't work? If so, that's a huge f*** up from Unity team side.

 

Do you use cloud build? If yes, try not to.

Untouched Unity works, but if you build HLAPI from Bitbucket and copy it in there then it doesn't

 

I guess nobody tested it after uploading. That's quite... professional

 

just regular build

 

Which Unity version? Can you try on another computer? Can you try Unity 2017.1.0p1?

I am not sure, maybe it only happens under some circumstances.
In either case, the lesson to be learned is that this whole Weaver thing might not be optimal. It's a pain to work with and modify - having all the scripts in the Project would be way easier.

 

Alright...

i installed Unity 2017.1.0p3 (only one i could find)
Applied your changes, and it worked!

i installed Unity 2017.2.0p3 again
Applied your changes, loaded up my client project and the following was spamming the console:

- I have verified to make sure i did not do anything wrong during copying/replacing...
- A new empty project did not spam the console(with your changes applied)
- Just importing the assets folder started spamming the console again
- I tested the editor without your changes, no errors

 

Can HLAPI Pro NetworkTransform synchronize the positions of specific axes only ? (eg X and Z only, not Y)

I can tolerate movement delay, but jump delay is unacceptable.
Therefore,I want to send a jumping event using Command and ClientRpc and update the Y axis position of the player character on other clients, but HLAPI Pro NetworkTransform always synchronizes the Y axis position.
I want to turn off the synchronization of Y axis of NetworkTransform during jumping.

 

Yes, we were discussing 2017.2 above. The HLAPI source for 2017.2 throws that error that you got and I asked the UNET devs above, but no one replied. So there's nothing we can do until they upload a HLAPI version that works.

Maybe later, I want to get it to work 100% perfectly first.

 

I am very glad to hear that!
I will continue to use HLAPI Pro NetworkTransform for my project.
Thanks!

 

This is most likely then the cause of my bug report posted before this... sorry for bothering you with it...

 

NetworkProximityChecker Suggestion/Request
( I did a quick scan of the thread and i believe there is no talk about this, if there is, apologies...)

1.) With my current project, i have separated the client and the server code, which is working quite well except for syncvars and NetworkProximityChecker. These will break with this approach... I am hoping you can fix that!

2.) I did some reading about the default NetworkProximityChecker and in my opinion it does not come close to what it is supposed to do!

In my opinion what it should do is, when the NetworkProximityChecker component is added to the server network object, the server should do a distance check per player vs network objects with an NetworkProximityChecker component and see which are within the requested range.

(You could add an interval maybe with/or some kind of spread?)

If these network objects are not in range, the server should stop any (NetworkTransform) updates to the player client and remove the network objects locally and inverse the action when they do come in range.

Is this possible?

 

2.) That's what it does. Sphere casts to find players in range, adds to observers, sync then sends it to all observers

No problem

 

huh... really... i was under the impression it only "hides" the local remote objects...
it would be awesome if it did all that!


-> Could you look into the fact that a client - server separated code run projects do not work with the NetworkProximityChecker?

I can supply you with the 2 basic projects setup if you want...

 

Why do you have 2 different projects? You can split the server side code and the client side code with global defines.
https://wobesdev.wordpress.com/2016/10/10/preprocessor-directives/

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.Networking;
4.  
5. public class NetworkManagerCustom : NetworkManager
6. {
7.     string login;
8.     string password;
9.  
10.     void Awake()
11.     {
12.         NetworkManager.singleton = this;
13.     }
14.  
15.     public override void OnServerDisconnect(NetworkConnection conn)
16.     {
17.         GameObject player = conn.playerControllers[0].gameObject;
18.         Save(player);
19.     }
20.  
21. #if Server
22.  
23.     // Server save system
24.     void Save(GameObject player)
25.     {
26.         login = "DatabaseLogin";
27.         password = "DatabasePassword";
28.  
29.         //save...
30.     }
31.  
32. #endif
33.  
34. }

The code between #if Server and #endif wouldn't be compiled into the client build. @vis2k is working in order to improve HLAPI in general, but not for fixing your wrong project architecture. So I would like to suggest for you to stop doing off-topics.

 

What are you talking about man, this is my preferred way of doing the client/server setup... has nothing to do with applying a wrong project architecture... there is no difference... the end result is all the same...

 

@vis2k

1.) The default NetworkProximityChecker seems to be broken..
i am assuming the network object never gets spawned locally...

The same happens after i update the editor with your editor files...
Verified it with 2017.1.03f

Anything you can do at your end?

-----------

2.) I would like to suggest an addition to the NetworkProximityChecker...
( i am sure you have nothing on your TODO list )


I am assuming it is cross checking -all- the server network objects that have the proximity component... i can imagine this becoming quite costly at some point were you to have a lot of them...

Would it be possible to assign groups to the proximity component?

NetworkObject_A - Group 1
NetworkObject_B - Group 8
NetworkObject_C - Group 999
NetworkObject_D(<you) - Group 8, 999

You do not receive any network updates from A
You do receive updates from B & C (that are within the distance check)


the developer needs to be able to add/remove groups to the proximity component...
the developer needs access to a list of members of the groups that meet the requirements

 

I just want to fix HLAPI bugs without breaking the architecture for now

 

Fair enough! - so what about:

 

Are you sure you are using it right?
It works fine for all my rather big UNET projects (uMMORPG, uMOBA, etc.) and no one mentioned that here before.

 

Hi,

I'm only interested by NetworkTransform reimplementation.

There is any way to have only this reimplementation without overriding the entire dll ?

Thanks

 

You can take code from bitbucket and make your own class. And use it instead.
There's no other way without replacing dll.

 

@aabramychev

a user having to update your unity code, what is that about ?

 

LLAPI actually works

 

i dont know any other tags to address so your awesome work gets noticed... sorry

i am assuming he knows other unity network developers

 

@vis2k

1.) Where can i find a description on Send Interval and Compress rotation from the Network Transform component; so i can understand the idea behind it better?

2.) Scripts attached to my network objects (deriving from NetworkBehaviour) show an interval send and channel description on the bottom of the component in the hierarchy... the send interval value here does not match the value i have set in the Network Transform component... No idea if this matters to you...


Thank you

 

1) Send interval = send every ... seconds
Compress = compress quaternion rotation floats into shorts or bytes. Just use the default if you aren't sure.

2) Yes, that's ok

 

Any news from UT team about 2017.2 source fix? I wonder if there's a quicker way to poke them.

 

as in
send an update every 0.100f = 10 updates/second?
send an update every 0.090f = 11.1 updates/second?
