Netcode 0.5.0-preview.5 'Cannot convert a owner predicted ghost 'prefabName' as a scene instance

Hi all.

following the tutorial on https://docs.unity3d.com/Packages/com.unity.netcode@0.5/manual/getting-started.html

When trying to setup the cubePrefab I see the error

This is because the 'sharedData' container object has the 'Convert To Client Server Entity' property 'Conversion Target' set to a non [Server] value

An area of confusion is that the 'Convert To Client Server Entity' is marked as obsolete

which suggests that there may be some transition from this class to the 'Convert to Entity' class.

I also have some serious confusion about the 'sharedData' object. It's instructed as created as an empty object, BUT it's later referred to as a scene.

This even further suggests that the current way to do networking is to use a subscene workflow (please comment a tutorial if you have one) and the 'Convert to Entity' class should be attached to it BUT it still causes this error in the title and listed above.

If anyone understands this and can help me know what to do please share.

 

best thing to do is just download the sample and look for the appropriate scene with the completed code. https://github.com/Unity-Technologies/multiplayer

 

I currently have the same confusion with the tutorial.
I wish there was a better way to keep the docs up to date as these things develop but I understand the situation and honestly its just nice to be involved.

Thanks for the tip @doingTheCodes

 

@CMarastoni Can u tell me more about sub-scene workflow? Is that next Netcode version has even better sub-scene workflow that able to decide specific sub-scene to client world or server world only? Like I want sub-scene A to client world and sub-scene B to server world and also the build pipeline will smartly build sub-scene A only into client build and sub-scene B only into server build.

 

I would also like this to be a feature.

 

Thanks for clarifying @CMarastoni!
No stress on the docs mate, the DOTS teams are doing an amazing job. It's a difficult task to keep documentation up to date with a rapidly evolving solution.

@optimise perhaps best to create a new thread? This one is 7 months old and I'd like to see discussion on your topic. Particularly interested in your use case.

 

Does anyone have a clean update example on how to get this to work? I'm a bit lost

 

Ok - I use netcode 0.6 + URP - and all pre subscene-gameobejct-conversion netcode versions worked for me perfectly but conversion with ss doesn't work at all(only in NetCode in Entities it shines). Of non dots packages I use only new Input system. I use HybridRendererV2 - 0.11.0
also I use unity 2020.3.24

So basically i created minimal NetCode project :
1. All cs files from NetCube sample(NetCube sample on github) are the same in my project except that I added just 1 line in OnCreate method of Game.GoInGameClientSystem - as a first line I added : RequireSingletonForUpdate<GhostPrefabCollectionComponent>(); (as suggested by Devs in one post on forum)

2. I added subscene and to subscene I added GameObject with GhostAuthoringComponentScript(DefaultGhostMode=OwnerPredicted), GhostOwnerAuthoring script and MovableCubeCompoentAuthoring component(from NetCube sample) - then i created prefab of this GO deleted GO and moved instance of prefab as a child of subscene (just in case)

Now when I close the ss(I'am new to ss so i guess it should be closed before we hit the play button(?)) I see in conversion log of ss(in inspector) error : Exception: InvalidOperationException: Cannot convert a owner predicted ghost raider as a scene instance

If I start the game nothing happens - it doesn't show any messages except that is HRV2 active - game doesnt react to inputs.

Here is NetCube sample on github : https://github.com/Unity-Technologies/multiplayer/tree/master/sampleproject/Assets/Samples/NetCube

So what I am doing wrong here - can someone explain me?Thx in advance
