How to properly use observers.

[nimble pier]

I am having a dedicated server , like my server is single instanced only .I have a persistent scene for lobby rooms, matchmaking etc, when clients connect to this server they can choose the appropriate game mode and launch a stacked scene version of the mode.
Now I am having scene mismatch errors when others player join primarily because sytacked scenes are laoded. What isa the appropriate setup for observers so that this is handled gracefully

The way the Network Manager is setup by default is the correct setting for this application.

Notably, the SceneCondition in ObserverManager.

Thus if a client is not added to a given stacked scene, he not received messages from scenes he is not in. Which is the most common source of this kind of error.

If you have overridden this SceneCondition on the prefab itself, you re-introduce the potential issue.

Okay technically what I want to achieve is that my stacked scene also have some network objects I am using for something. Is it possible that my stacked scene network objects are not observed by other clients , only the clients who are prt of that stacked scene

How will the condition look for them ?

Look at the screenshot above

I tried the above but still gets the same error with network objects

If I remove all network objects then it works fine even with stacked scenes

^

any network object, not just prefab actually

[nimble pier]

Yes so what should I do so that network objects are observed by the clients that are stacked scene versions only ?

[nimble pier]

Are there any tutorials or example projects where you have created a custome obsrver condition ?

[teal hollow]

... see the above example 😛

[teal hollow]

search for t:ObserverCondition you'll see bunch of pre-made one, you can consider them examples and look how you have to implement the logic

[nimble pier]

I tried with scene condition. It is not working. What I meant is if I had to use matchcondition how do I customise the parameters such as connection, match etc

Like create a completely new scriptable object ?

Or refer them in my game manager and change function parameters

Do you guys have a sample project where you have use observers and conditions extensively ?

Or have handled multiple scenes with network object and scene stacking component together ?

[teal hollow]

They are pretty simple, so I'm not sure if there is a more extensive use of them other than Lobby and World supporter project

[teal hollow]

You inherit from SceneCondition and you implement whatever logic you can imagine

[nimble pier]

But Lobby and world do not have multiple scenes with Network object in both of them. The Game scene do not have any network object.

[teal hollow]

Yeah, the players

Docs : https://fish-networking.gitbook.io/docs/manual/components/network-observer#conditions

[nimble pier]

The player spawn and remain in the main scene only not in stacked scene. I am abel to replicate the same but I need like if I had a networked object in my scene, how do I make sure only selected connections observe that

Let me try the inhertiance way

[teal hollow]

I know I've already answered this specific question multiple times, but once again, look at the example here:

That is the ONLY condition needed to present to fulfil your requirements.

Once again. If the condition is missing, it's because you are overriding it on the object itself in the observer component

[teal hollow]

That's not how King of the Hill work though

[nimble pier]

This works if there are no network objects in the scene I am instancing other than it start throwing all sorts of exceptions. Maybe inheriting and overriding is the way to go

[teal hollow]

I'm telling you no, but have at it.

[nimble pier]

I re ran the king of hell project I get what you are saying let me have a spin again maybe I got it confused somewhere

@teal hollow When players spawn are they spawned in persistent scene and moved to stacked scene or they are spawned in the instanced scene only for king of hill project ?
