com.unity.netcode.gameobjects VS Sumo101

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!

So I've been following some tutorials online and have been trying to create a multiplayer 3D game, and so far, all I want to do is for two clients to be able to connect to a server, spawn their players (spheres), and move their spheres around and into each other, causing collisions. I have created a player movement script to handle input - just simple WASD and space-jump movement. To handle the networking, I followed Tarodev's Netcode video to set everything up. Here is where the problem begins. Using ParrelSync, I run the game on one editor and a clone on another. I then use a GameObject with the NetworkManager script to start a host on one editor, and a client on the other. Upon connection, the client and host both spawn players, but then the problem begins. As the client's player starts falling down, the host's editor starts experiencing errors and warnings. As mentioned in the title, here they are: [Netcode] Behaviour index was out of bounds. Did you mess up the order of your NetworkBehaviours? [Netcode] Network variable delta message received for a non-existent behaviour. NetworkObjectId: 2, NetworkBehaviourIndex: 2 I did a bit of digging and found that the error was being thrown by a function in the NetworkObject script, but I couldn't really understand why or how to fix it, hence this post. Errors are only thrown on the client when the host moves its player, and errors are only thrown on the host when the client moves its player. The transforms of the players are not being transmitted between host and client at all, despite the player prefab having a Client Network Transform script, and a NetworkObject script. Here is the link to the code if you want to reproduce the error or understand it better: https://github.com/XR101/Sumo101 Any help would be appreciated as this error is driving me insane.
