com.unity.netcode.gameobjects VS LiteNetLib

There was this issue: Custom Serialization can't be used because of compile-time error in RPCs. · Issue #665 · Unity-Technologies/com.unity.netcode.gameobjects (github.com) and this one Error in editor ArgumentException: An item with the same key has already been added · Issue #714 · Unity-Technologies/com.unity.netcode.gameobjects (github.com) Though I guess there has been many changes on Network for GameObjects since then.

Ok so while writing this I went and found in the github project for the netcode gameobjects an example of grabbing an item, have a look~ https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/blob/develop/testproject/Assets/Scripts/GrabbableBall.cs

Netcode for GO: https://github.com/Unity-Technologies/com.unity.netcode.gameobjects

Turns out downgrading Netcode for Gameobjects from 1.0.1 to 1.0.0 is the solution for this. Here's the link for the working version of Netcode: Netcode v1.0.0

Steam Networking (I used Unity therefore, this was also very helpful: Facepunch Steamworks / MLAPI)

This is in NetworkTransform line 360 in the Unity Netcode https://github.com/Unity-Technologies/com.unity.netcode.gameobjects/blob/9ffd22b158fbac5ea824cb7e9e237d2d8b782ed0/com.unity.netcode.gameobjects/Components/NetworkTransform.cs

I bet you're using Mirror. I peeked at their code base (and Unity's new netcode project) and decided to write my own networking framework instead. It sucks to be stuck with problems that someone else created.

I think they rebranded it to netcode for gameobjects. Github repo seems to update daily: https://github.com/Unity-Technologies/com.unity.netcode.gameobjects

E.g. We just released Boss Room, our new multiplayer sample game. It is built using our experimental version of MLAPI, the mid-level netcode Unity acquired last year. MLAPI is fully open-source under a MIT license. We're continuing to develop it in the open, taking both RFCs and PRs from the community. More info can be found both on our GitHub page and Multiplayer Docs site. https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi https://docs-multiplayer.unity3d.com/ Best wishes!

I personally use this LiteNetLib

Been using LiteNetLib for our current project and it is pretty nice

Currently I'm using LiteNetLib (https://github.com/RevenantX/LiteNetLib) and it's working pretty well. There is a little input lag but it's more than acceptable.

Check LiteNetLib. Judging by your requirements simply passing coordinates back and forth between two clients should work. Designate one of the games as host and the other as client, but just pass coordinates would work over LAN. Optimise from there if gameplay isn’t thet smoot by lerping between past and newly received coordinates.

For networking, file IO, and streams in general, there's Korio and for Java; for just networking, there's LiteNetLib for C#; for what looks like data streams in general, there's Okio also for Java; and Tokio for multi-threaded IO in Rust.

I've been a bit "Unity offline", and even more so when it comes to networking solutions, because of my real job :), but LiteNetLib is quite good. There's also a new HLAPI solution called FishNet which seems very interesting.

This might be handy for you :) https://github.com/RevenantX/LiteNetLib

they might be using LiteNetLib as their low level transport.

You definitely want to a low level API (LLAPI) instead, like f.ex. LiteNetLib, ENet, lidgren or similar. I haven't touched anyone of these recently, except the first one a year-ish ago, so I won't say anything about where they stand today.
