midlevel / mlapi.relay Goto Github PK

Was already posted on the discord... theres a weird exception going on when using the relay... It happens completly randomly but is game breaking.

This went crazy in the mlapi discord a few days ago... we simply couldnt figure out how to use this packet... and ruffles didnt worked either ( It spammed errors ). So we needed to copy a bunch of dll files into the publish folder of the builded project.
Could you please add an full example of usage and ruffles support ? I bet you would make many, many people happy.

using Ruffles.Core;

private RuffleSocket socket;

socket.Disconnect(connectionId, true);
socket.Send(payload, connectionId, channelId, false);
socket.RunInternalLoop();
are all not contained in RuffleSocket

I'm getting the below error when connecting from unity to the relay running on a amazon EC2 instance:

[MLAPI.Relay] The MLAPI Relay detected a CRC mismatch. This could be due to the maxClients or other connectionConfig settings not being the same UnityEngine.Debug:LogError(Object) MLAPI.Transports.UNET.RelayTransport:BaseReceive(NetworkEventType, Int32, Int32&, Int32&, Byte[], Int32, Int32&, Byte&) (at C:/projects/mlapi/MLAPI/Transports/UNET/RelayTransport.cs:399) MLAPI.Transports.UNET.RelayTransport:Receive(Int32&, Int32&, Int32&, Byte[], Int32, Int32&, Byte&) (at C:/projects/mlapi/MLAPI/Transports/UNET/RelayTransport.cs:284) MLAPI.Transports.UNET.UnetTransport:PollEvent(UInt64&, String&, ArraySegment1&, Single&) (at C:/projects/mlapi/MLAPI/Transports/UNET/UnetTransport.cs:92)
MLAPI.NetworkingManager:Update() (at C:/projects/mlapi/MLAPI/Core/NetworkingManager.cs:642`

It's unclear what the correct settings for the Networking Manager script and Unet Transport should be in order to satisfy the requirement of matching up with the config.json settings of the relay.

As I'm working with getting the relay server up and running, I was thinking it could be good to have some extra messages sent to the frontend so the host/client can better understand what is happening on the relay server side.

1. When a host creates a new room, a message can be sent to the frontend with the IP/Port the host is on as the relay server seems to be setting a random port each time a new room is made.
2. A error message to the client trying to connect to a room that doesn't exist.

From there front end can handle it however they please.

I have started this kind of in my fork with TODOs. However, I don't understand how the room.Send() method works, my netcode knowledge is novice.

Thanks

Hello,

I am having an odd issue where sending fragmented messages over the relay causes a IndexOutOfRangeException. Sending over fragmented channels works fine, but as soon as the message is too large and needs to be fragmented, issues occur.
This issue doesn't happen without the relay.

Sending a fragmented message from the Server to the Client causes this to be repeatedly output into the Relay server itself

[ERROR] Exception during loop: System.ArgumentException: Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.

Sending a fragmented message from a Client to the Server causes this to be repeatedly thrown into the Host PC (not the relay server)

MLAPI.NetworkingManager.Update () (at <10b4ebfb14e04d6583eb858de486f4fc>:0)

I am using the UNET transport, and the config.json is configured correctly (no CRC errors). I've also made no changes to the source code, i've only compiled it and am running the server on Linux

Hello,
Is it possible to use this relay with the Mirror framework? If not how to add support for it?
Thanks.
