com.unity.multiplayer.samples.coop VS com.unity.netcode.gameobjects

Have a look at https://www.photonengine.com/# Or the "new" built in thing from unity itself https://docs-multiplayer.unity3d.com/ (on the last link you find an example project "boss room" that shows how to implement multiplayer. When playing over the internet, you must "just" specify the correct host)

I'd recommend reading up on Unity's Multiplayer Networking: https://docs-multiplayer.unity3d.com/

We used dedicated servers from Unity, as outlined on Unity's official website https://docs-multiplayer.unity3d.com/

They have their code available here. I don't have any others, though. Hoping others will chime in on this thread with more!

URL: https://github.com/Unity-Technologies/com.unity.multiplayer.samples.coop.git?path=/Packages/com.unity.multiplayer.samples.coop#main I get this from unity netcode docs.

That's a question you should ask your programmers after they skimmed the documentation of multiplayer in Unity, not random people on the Internet.

Multiplayer is not directly part of the engine. Unity has their own services for multiplayer, but there is no rule that says you have to use it. In fact when I started most people where using Photon, because Unity didn't have their own service at the time.

You'd have to dig into the multiplayer offerings.

You could check out the Unity demo apps, like Boss Room. The newer demos from 2022 aren't on GitHub yet.

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!
