How do I sync TMP texts? I want to

[plucky river]

NetworkVariable<FixedString32Bytes> playerName = new(string.Empty,writePerm: NetworkVariableWritePermission.Owner);
public TMP_Text playerTag;

 public override void OnNetworkSpawn()
 {
     if(HasAuthority)
     playerName.Value = new FixedString32Bytes(AuthenticationService.Instance.PlayerName.Split('#')[0]);
     playerName.OnValueChanged += OnPlayerNameChanged;
     OnPlayerNameChanged(string.Empty, playerName.Value);
}
 void OnPlayerNameChanged(FixedString32Bytes previousValue, FixedString32Bytes newValue)
 {
     playerTag.SetText(newValue.ToString());
 }
}

I don't use NetworkSpawn, because there is no spawning done in the scene right now. All I do is serialize the string with Inetworkserializable, then assign a playername, and then make a server rpc send the TMP's text through.

@plucky river what would you do in this case? Is this a bad code principle right here?

[plucky river]

RPCs have to be in a network behavior on a spawned Network object. So it needs to be spawned regardless of RPC or Network Variable

[pastel raven]

Well, right now what I do is just have 4 objects (networkObjects) and whenever a player joins, it sets 1 more active.The script itself is NetworkBehaviour, so what am I missing?

[pastel raven]

I probably have to spawn the object but do I have another solution?

[plucky river]

no, it has to be spawned if you are sending data

You could use Custom Messages if you don't want to deal with Network Objects

[pastel raven]

I'm fine with NOs I believe, I just don't understand how could I spawn the object when it is already on the screen? Do I just spawn it on awake as a one-liner?

[plucky river]

also keep in mind that late joining clients will not get previous RPCs or Custom Messages

[plucky river]

In scene objects are automatically spawned

[pastel raven]

I won't have late joining in my game I know that thanks.

[pastel raven]

Then why is the RPC not going through I wonder?

Do they have to be a prefab?

[plucky river]

just make sure that you are loading the scene with NetworkManager.SceneManager

[pastel raven]

Well I have only 1 scene.

If they have to be a prefab fine, but they're not. They're just called 'LobbyPlayer' 1-4

[plucky river]

They don't have to be

[pastel raven]

Let me read this through

[pastel raven]

Okay so apparently the RPC now runs (it didn't run before) but the text still didn't change

[pastel raven]

For the host if the name is WASD and the client its ASD, it shows on the host that both names are WASD on the client, both are ASD

[plucky river]

If your Lobby players are scene objects they are all owned by the Host. You will need some way for the client to send its name to the host so the host can assign the proper name to that Lobby Player

[pastel raven]

Isn't that done with serverRpcs

Thats why I send ServerRPC data for the clients

[pastel raven]

But it seems I'm doing it wrong I believe

[plucky river]

ServerRPC should work. Make sure you aren't using any Sinlgetons. That tends to not work well with networking

[pastel raven]

ServerRPCs don't really work, maybe its just me being silly.

I'm not using any singletons

[plucky river]

You need to send the playername in the RPC

[pastel raven]

Seems to not do anything else

[plucky river]

playerNameText needs to be set to the playerName that the RPC is sending and not the public one in the class

[pastel raven]

I'm sorry I don't understand this statement.

[plucky river]

this code is grabbing whatever playerName is set locally. The client needs to send its playerName as a parameter in the Server RPC to the server

[pastel raven]

This was my code

[plucky river]

That should work. You don't need the isOwner check unless this was spawned as a player object

[pastel raven]

Well the way this works is on the host both lobbyPlayer names are the same, on the client both lobyPlayer names are the same as well, but the names are different

But where should the serverrpc be located?

Inside the LobbyPlayer script or a manager script?

[plucky river]

It needs to be on the lobby player object that has the text element

It could be on a manager object if that manager is also keeping track on lobby players and their nam

[pastel raven]

Well, it is, I don't know whats causing the issue that the name is the same on the host and the client

[pastel raven]

Can I somewhere find a sample or a video where they explain or I can look into this @plucky river ?

[plucky river]

You can check out Code Monkey's Complete Multiplayer Course. There is a lecture on RPCs

[pastel raven]

Yeah I watched the full stuff and did it like months ago

Guess I'm gonna watch it again

But he doesn't sync this particular case

[pastel raven]

I found the problem @plucky river . The problem is that The PlayerData.playerName is always the Host's name which is weird.
Other than this, the RPCs and everything works. I just don't know how the playerName is the same for all (btw I'm using Lobby, and the OwnerClientID is 0 on both instances because I test it on the same pc, however I have different names setup in the lobby player settings)

[plucky river]

For in scene objects the owner client ID will always be 0. normally you would spawn lobby players in dynamically so they have the correct owner.

PlayerData.SetPlayerName() looks like a static function. that will get overridden when each player name you set

[pastel raven]

Yes you were right! I solved it before reading this but nevermind

[pastel raven]

Now there is just one issue left, the testing. Whenever I try to test with parrelsync, it says that the player is already in the lobby, and the ownercient id is 0 in both players

[plucky river]

You need to change the Authentication Profile when using the same PC to test.

[pastel raven]

Alright thanks

I seem to get this error a lot, why could be it?

[plucky river]

try updating to NGO 1.11. I belive there were some fixes to FixedStrings

[pastel raven]

How do I do that? Thats not a stable version?

[plucky river]

That is still 2 or 3 versions behind the most recent stable version. If you are not seeing in the package manager then you can add it by name and specify the version number

[pastel raven]

I don't use that version because it generates various problems and errors for me. The last problem I believe is that both OwnerClientIDs are 0 but the profiles are different. Can that be a problem?

[pastel raven]

I still think that this Ownerclientid problem generates that error.

Have you ever met this error?

[plucky river]

Not since updating to Unity 6 and NGO2.0. There was an issue with using Fixedstrings in network variables but it's was fixed a while ago.
