Hi there,

I'm experiencing a crash on iOS 9.3.5 (works perfect on iOS 10 and later versions) with XCode 10.2.1 and Unity 2018.3.11f1.

It crashes when I call Mirror.Ignorance:ClientConnect(String).
That line:
int32_t returnValue = reinterpret_cast<PInvokeFunc>(enet_host_service)(___host0, ___event1, ___timeout2);

in: Native_enet_host_service_m48FBC7FF96DFB99185B042148A1B5F95D6BD9AC6

There is not much details about the error, just:

dyld`dyld_fatal_error:
-> 0x1febf08c <+0>: trap
0x1febf090 <+4>: nop

Any idea where it can come from?

Thanks a lot for your help!

https://github.com/SoftwareGuy/Ignorance#installation "Download the Unity Package from Releases". It would seem the mirror package no longer contains the Ignorance-transport.

Reported by user in the Mirror Discord

• Ignorance was working fine before adding Firebase database functionality
• Works fine in the editor
• Build game, cannot find enet.dll error
• Unity looking for the DLL in Mono folder instead of Plugins

Extra info:
I've found that including any of the Firebase native dlls in the project will cause this issue to happen, as soon as I disable them in the standalone enet works fine, but of course Firebase doesn't work now.

Repro project provided? Yes.

Here is the same thing reported as the conversation in Discord:

I am struggling to connect IgnoranceThreaded or IgnoranceClassic while running in the PlayFab MockVM Agent locally on my Windows 10. It works just fine with Telepathy Transport.

Here is my MultiplayerSettings.json file when trying to connect with Ignorance

    }
}

And here is the setup in Unity:

And this is how I assign the port:

public virtual ushort Port
{
    get
    {
        ushort invalidValue = 0;

        switch (transport)
        {
            case IgnoranceClassic ignoranceClassic:
                return (ushort) ignoranceClassic.CommunicationPort;
            case IgnoranceThreaded ignoranceThreaded:
                return (ushort) ignoranceThreaded.CommunicationPort;
            case TelepathyTransport telepathyTransport:
                return telepathyTransport.port;
        }

        Debug.LogError($"There is not a supported transport attached to this {GetType().Name}", this);
        return invalidValue;
    }
    protected set
    {
        switch (transport)
        {
            case IgnoranceClassic ignoranceClassic:
                ignoranceClassic.CommunicationPort = value;
                return;
            case IgnoranceThreaded ignoranceThreaded:
                ignoranceThreaded.CommunicationPort = value;
                return;
            case TelepathyTransport telepathyTransport:
                telepathyTransport.port = value;
                return;
        }

        Debug.LogError($"There is not a supported transport attached to this {GetType().Name}", this);
    }
}

I'm at a loss here as to why I can't connect locally in the Docker Container with the Mock VM Agent. Telepathy works just fine over TCP but Ignorance does not. I've opened up the ports and communication on my firewall for both TCP and UDP but still no luck. Even with those ports not opened on my firewall, communication still works just fine locally over TCP so that is not the issue. Any help would be extremely appreciated.

Here is the docs for the PlayFab Docker Container: https://docs.microsoft.com/en-us/gaming/playfab/features/multiplayer/servers/locally-debugging-game-servers-and-integration-with-playfab

(A note for the end-user: don't use this bad abstraction of the ENet in any of your projects, especially if you are creating a non-hobby stuff)

1. Don't allocate buffers dynamically on the heap here and here. If arrays are not moving across threads, then allocate them once like this and reuse all the time. You need to expose API to provide the actual length of the payload since you need to allocate large buffers. If arrays are moving across threads, use ArrayPool from NetStack or System.Buffers from NuGet, the implementation is almost the same.

2. You are currently dispatching one event per frame which will lead to such issues. Read my last comment there.

3. You should separate channels and delivery types as it was designed originally, right now you force head-of-line blocking which is counter-productive when you use multiplexed UDP transport.

4. You should include .meta files for native libraries and explicitly assign each to appropriate platforms and CPU architectures, especially for Android.

Research and implement a way to do LAN Discovery, so Ignorance can search the local network for any other game servers running using Ignorance.

Implementation to be determined.

Continuing my trend of reporting the same issue in every single transport...

Certain code in Mirror (specifically the scene load code) is dependent on pausing the transport on the client/server to ensure messages don't get sent out of order. As such, there are two checks within Telepathy.

            // note: we need to check enabled in case we set it to false
            // when LateUpdate already started.
            // (https://github.com/vis2k/Mirror/pull/379)
            if (!enabled)
                return;

            // process a maximum amount of client messages per tick
            for (int i = 0; i < clientMaxReceivesPerTick; ++i)
            {
                // stop when there is no more message
                if (!ProcessClientMessage())
                {
                    break;
                }

                // Some messages can disable transport
                // If this is disabled stop processing message in queue
                if (!enabled)
                {
                    break;
                }
            }

In Ignorance, only the first check is in place
https://github.com/SoftwareGuy/Ignorance/blob/master/Assets/Mirror/Runtime/Transport/Ignorance/IgnoranceThreaded.cs#L122
The second check is nowhere to be found.

This is most likely the cause of #58 as well.

I'm experiencing same problem as #3. When I run demo scene and press "LAN Host" I get an error:

DllNotFoundException: enet
ENet.Library.Initialize () (at Assets/Mirror/Runtime/Transport/Ignorance/Dependencies/ENet.cs:1059)
Mirror.IgnoranceClassic.InitializeENET () (at Assets/Mirror/Runtime/Transport/Ignorance/IgnoranceClassic.cs:376)

Steps to reproduce:

1. Create empty Unity project (Unity 2019.2.2f)
2. Import Mirror asset pack (v3.20.0)
3. Import Ignorance asset pack (v1.3.3)
4. Run IgnoranceClassic_BasicScene or any other Ignorance demo scene
5. Hit "LAN Host" button

Environment:
macOS 10.14.4
Build target platform is PC, Mac & Linux Standalone

Build Settings

REMOVED

EDIT: This is only applicable to the mirror2018 branch. master seems to not have this issue.

If one spams the NetworkManagerHUD's "LAN Client" to connect to a Ignorance-powered server, most of the time it will connect and start pumping data correctly. However, if one is fast enough to click "Cancel", then the actual loop that does the data pumping isn't aborted while it is in the Connecting state for some reason (OnClientDisconnect callback doesn't seem to be called). Thus, if you do get a connection, you can end up with 2 connections sending/receiving data on the client instance.

Originally thought to be an ENET problem, it seems that it could be either ENET, something in Mirror (i'm guessing it is likely to be that) or Unity's handing of some functionality. I am not sure. This can be classified as a game-breaking issue if you just have bad luck.

References
Issue #39 on ENET-C#, https://github.com/nxrighthere/ENet-CSharp/issues/39

Unity version 2018.2.20.

It seems that if you try to connect a Unity Editor that is in client mode to another Unity Editor instance that is in Host mode on the same computer (127.0.0.1/localhost) then the Unity Editor in client mode will not be able to connect to the localhost server counterpart.

Originally reported by Miles Every on the Discord. Confirmed that the bug exists by testing and can replicate the issue locally on my MacBook Pro.

Reproducible using the project (download it here). Open two Unity Editors with the project (you might need to make two copies of the project, since you can't have two editors open on the same project files). On one editor of the project, open the Pong scene, click "LAN Host". On the other editor, open the same scene and choose "LAN Client". This will attempt to connect to localhost... and should fail. The Peer object while it's in this state is stuck on "Connecting".

Does not seem to happen if you connect to a Windows Editor instance from the Mac Editor as a client. Windows Editor to Windows Editor instances are literally bullet-proof.

Seems that ENET's maximum connections is how many connection slots that will be used by the server. Connecting and then disconnecting clicks down the remaining slots.

ie. 4 slots = 4 connection capacity, no more after that. Not "I can run 4 connections at the same time".

For example, using Mirror's example pong scene and connecting to the same server more than 4 times will cause the transport to be dumped back to the unconnected state.

Will need a work around. Maybe need to poke upstream to ensure my facts are right

I tried to make Ignorance work with Insight with no success.
Is it possible to make it work without the NetworkManager binding ?

Hi. I have a question regarding the Channels list inside Ignorance script parameters.
Is there a specific reason why the minimum number of channels is 2 and it's not possible to choose unrealable only channel?

My project use case is local ethernet network only, so (assuming there won't be any packet loss) I would like to try to achieve minimum latency possible with unrealable udp connection (preserving packets order would be nice though)

The following two metafiles have been modified by Unity because the guid is duplicated.

https://github.com/SoftwareGuy/Ignorance/blob/master/Assets/Scenes.meta
https://github.com/vis2k/Mirror/blob/master/Assets/Mirror/Examples/Lobby/Scenes.meta

Perhaps the following tweet may be relevant.
https://twitter.com/mustankatti/status/999652822533591042

Hello i tried switching to Ignorance but it does not connect to the server ( timeout ).

Tried binding server to 127.0.0.1 and local network ip ( 192.168.2.10 )

And tried connecting to: localhost, 127.0.0.1, 192.168.2.10

I also disabled windows firewall just in case.

Nothing is working 👎

Would it be possible to remove the references into NetworkManager? That would allow seamless integration with Insight.

Hello.

In the readme you say that we should use the Mirror version that is on the asset store.
on the 06/08/2021 the version on the asset store is Mirror 42.2.12
I have imported Mirror 42.2.12 in a Unity 2019.4.24f1 empty project
I have imported Ignorance-v140b6.1-20210614.unitypackage
and this is what happen :

Hello @SoftwareGuy !

I was looking into using Ignorance for a project, and was wondering if you have any future plans for implementing some form of optional UDP encryption such as DTLS or an alternative.

Im not fully sure if this is something which would be implemented in Ignorance itself, or in the ENet side of things but I can see it being a useful adition in some scenarios.

No idea why this would happen, but adding it here on the to-do list for analysis and bug spray.

Check why Ignorance won't work with uSurvival.

Suggested by Miles Every, this would make changing transports easier.

ConnectionPort would become port.

I used the ignorance library under macOS, but it reported an error

Unhandled exception. System.DllNotFoundException: Unable to load shared library 'enet' or one of its dependencies. In order to help diagnose loading problems, consider setting the DYLD_PRINT_LIBRARIES environment variable: dlopen(libenet, 1): image not found
at ENet.Native.enet_initialize()

Environment:
macOS 10.14.5
dotnet3.1 console

I'm using libenet.bundle, I also use xlua, but xlua is dylib format, no problem, please advise how to solve it?
Or how do you convert a bundle to dylib?

Just got the latest versions of Mirror and Ignorance but when I bring ignorance in I get the error:
Assets\Mirror\Transports\Ignorance\IgnoranceTransport.cs(225,30): error CS0115: 'IgnoranceTransport.GetConnectionInfo(int, out string)': no suitable method found to override

Hello. I wondered if you are still updating Ignorance? I just upgraded to Mirror 53 and hit an error. It works ok with Mirror 44.0.2 (I'm using Unity 2021.1.25f1)
If you are still able to help I'll send you the error. I just wound back and didn't save it!
Many thanks
Mark

Can you consider giving priority to the stable version of mirror? thank

I mentioned something I am trying out over here in this issue:

SoftwareGuy/ENet-CSharp#41
SoftwareGuy/ENet-CSharp#41 (comment)

I'm just opening an issue to track it here as well as it is specifically Ignorance that I am using to test it with. Quote of comment here for ease of reading:

@SoftwareGuy I was doing some digging around on this as I'm also in need of Mac and hopefully soon PlayStation, XBox, and Switch support. I found this:

https://docs.unity3d.com/Manual/PluginInspector.html

And this:

https://forum.unity.com/threads/how-to-setup-this-windows-player-c-source-code-plugins-for-il2cpp.537269/

Reading through it, it sounds like Unity supports including native C code in your project and it will compile it in the il2cpp build process. It won't work in mono builds or Editor (because of mono).

I'll try it out with enet and if it works, it should make it so enet supports all platforms unity compiles il2cpp with (which I think is all of them).

I'll keep this issue updated with my findings and put in a PR for review if it works on my local.

changing my platform to Mac while on a windows machine. It's trying to load libenet when it should be loading Enet.

Thanks :)

When running in an offline server where it connects to itself in order to allow network objects to work, we disconnect and reconnect to a new server, however the ENet plugin crashes due to some sort of invalid pointer address.

Is there a version that has symbols that we can use to debug the exact problem?

Thanks!

========== END OF STACKTRACE ===========

Describe the bug
networkConnection.Disconnect() calls have no effect. Using the debugger revealed that connection is still present in NetworkServer.connections after Disconnect is called. I have used basic authentication component to demonstrate it, since this is how I discovered it and it is among the faster ways to set up, but this error is not limited to it. This happens on both client & server. Switching to Telepathy makes everything run smooth. NetworkManager OnServerDisconnect event is also not fired, since no actual disconnect carries out. With enabled debug both on server & client a log message is printed

Ignorance: Client disconnection acknowledged

Repro project

• Create empty project in Unity.
• Import Mirror.
• Import Ignorance (Last release QualityOfLife-136-20200130).
• Open Ignorance Threaded example scene.
• Add Basic Authenticator component and drag it into Network Manager

To Reproduce
Steps to reproduce the behavior:

1. Build Player for Windows x86_64 with Mono backend
2. Open 2 instances of the player (One in editor to change password from inspector, one in standalone player)
3. Launch Host/Server on one instance
4. Connect to first instance from the second with incorrect credentials.

Expected behavior
Client disconnected from server.

Actual behavior
Client is stuck in the middle of the connection procedure.

Desktop

• OS: Windows 8.1 x64
• Build target: Windows x86_64 Mono
• Unity version: 2019.2.14f1, 2020.1.0b5
• Mirror branch: 11.4.2, 12.11.0

The server doesn't work on iOS (no matter the version) with Unity 2018.3.11f1 and XCode 10.2.1.

If I run the Mirror example Basic, click LAN Server Only then try to connect from another device, nothing happens.
It works fine when I do the exact same thing with an Android device or with Unity Editor.

What is the current reason for limiting to 4096 connected peers? And what modifications would be needed in order to increase past this limit?

We've been running some optimizations to Blocky Ball so that we are ready for the game to scale when we launch mobile. We've set up session based matches so one running game server executable handles multiple matches between different players. We are looking to be approaching this 4096 connected peer limitation.

Thanks again for all of the hard work on Ignorance! :)

Describe the bug
Player crashes after client connects in the second host instance with Ignorance Threaded. Switching to Telepathy makes program run normally. This issue only happens if server is terminated with clients still on, if server is empty is operates normally (local client in host mode does not count). This issue happens both in Host and Server only modes.

Repro project

• Create empty project in Unity (I have checked and this bug is present in 2019.2.14f1 and 2020.1.0b5).
• Import Mirror (Tested asset store version 11.4.2 and latest release 12.11.0)
• Import Ignorance (Last release QualityOfLife-136-20200130)
• Open Ignorance Threaded example scene

To Reproduce
Steps to reproduce the behavior:

1. Build Player for Windows x86_64 with Mono backend
2. Open 2 instances of the player
3. Launch Host/Server on first instance
4. Connect to first instance from the second.
5. Stop Host/Server on first instance
6. Launch Host/Server on first instance
7. Connect to first instance from second.

Expected behavior
First instance successfully accepts connection.

Actual behavior
First instances crashes.

It seems that some Android devices block LAN Host mode on Android with Ignorance/Telepathy/et al with Mirror, but work with deprecated Unity UNET.

Investigate why this happens. Ignorance 1.3 works fine with an Android OS LAN Host and the Unity 2018.4 Editor connecting to the device itself. Maybe Ignorance 1.2.6/1.2.7 has a bug?

Hi,

I upgraded my project to 2018.2.20f1 then dropped Mirror(2018) and Ignorance (2018 latest release) in the project, I also changed Scripting Runtime Version to .NET 4.x Equivalent.

I am currently stuck with the error below

Assets/IgnoranceTransport/Dependencies/UnityAsync/TaskYieldInstruction.cs(21,45): error CS1061: Type Task' does not contain a definition for IsCompleted' and no extension method IsCompleted' of type Task' could be found. Are you missing an assembly reference?

Version 1.3.0 gold release. Unity 2018.4.5
I started host for several times in editor. And stop then run again. Throw the exception: Host creation call failed.
I used the cmd to check the ports. The editor is still using that port after stop run. I don't know if it will cause the problem on other platform.
So if it's possible to stop the port after running?

I am trying to use Ignorance instead of Telepathy, because we use Dissonance Voice Chat and they advise against using a TCP Transport, but I have run into a problem with spawning scene objects. There are two Functions in Mirror.ClientScene: PrepareToSpawnSceneObjects() and SpawnSceneObject(SpawnMessage). The former has to be called before the latter, but when I use Ignorance (Classic or Threaded), they are not always in the correct order, presumably because of the unreliability of UDP (the ObjectSpawnStartedMessage arrives before the SpawnMessage). This happens only on the client and only sporadically.

Is there a way to fix this or ca I just not use Ignorance/UDP?

posting them all in one place for now.

weird indentation

weird indentation. also the 'costs?' is kinda weird. if you don't exactly know what it does then feel free to leave compression out of it for now. having an uncompressed enet transport is valuable already.

whitespace

remove this

personally I wouldn't worry about buffering until ignorance is 1000% stable. telepathy doesn't buffer (yet) either.

use dictionary.TryGetValue instead of containskey+lookup. faster and shorter.

use trygetvalue

processservermessage:

copy exactly the received packet into a byte[] and then call onserverdatareceived.invoke with the exact packet that was received. don't copy the whole packetdatabuffer in there.
not sure if you have to call incomingevent.packet.dispose either. C# will probably do that for you. unless there is a enet-sharp thing that require you to do that.

https://docs.microsoft.com/en-us/dotnet/api/system.collections.generic.dictionary-2.remove?view=netframework-4.7.2 just remove, no need to check containskey first.

this allocates a new arraysegment each time someone uses any mirror function with ignorance. probably better to go back to your old serversend without arraysegment. and if you still want arraysegment support then have another serversend function that does that.

trygetvalue

are you sure this works if I am on linux and build for osx? maybe this requires application.platform==osx check? (not 100% sure)

copy directly into a byte[] with exactly the size that you need here too. less magic for now, stability is important, especially if you still have random errors in places.

allocates a new arraysegment each time someone calls it from mirror. see above.

usually better to do this with a git branch instead. but it's fine as long as you remove the old functions later.

is this even needed if you only run ignorance from unity?

imho a 'bool logDebug' is enough. people should always see warnings and errors.

trygetvalue

copy into a byte[] directly like explained above

fix indentation

Versions:

Mirror Version 26.2.2

Hi,

I am trying to build Mirror Ignorance on iOS however some referenced functions seem to be missing from libenet.a. nm tools show me the functions are missing.

However the same functions are missing in the windows .dll and it compiled and ran fine...

The missing functions seem to be referenced in ENet.cs but no idea why it works under windows

Any ideas, really would like to use UDP with our voice chat : /

Hi,

Are there any plans to decouple Ignorance from Unity? We are looking to integrate the transport layer provided by Ignorance but we want to use our own non-unity networking library on top.

Thanks!
