Method with ServerRpc not being called

Pretty simply, I have two methods that I want to run when a button is clicked. The first functions properly. The second works up until I add the [ServerRpc] Attribute. I've tried it without (RequireOwnership = false), I tried removing ServerRpcParam. But as far as I can tell the code inside of TogglePlayerReadyServerRpc is just never even viewed or run though

Code (CSharp):

1.  
2.     private void ClientOnReadyClicked()
3.     {
4.         TogglePlayerReady();
5.         TogglePlayerReadyServerRpc();
6.         print("This is printing");
7.     }
8.  
9.     public void TogglePlayerReady()
10.     {
11.         print("This is printing");
12.     }
13.  
14.     [ServerRpc(RequireOwnership = false)]
15.     public void TogglePlayerReadyServerRpc(ServerRpcParams serverRpcParams = default)
16.     {
17.         print("This is not printing");
18.     }

 

Are you observing the console on the server or just the client where you click the button? Cause the client won‘t execute a ServerRPC method, it will send a message to the server so that the server executes that method. Just in case you weren‘t expecting that.

Second thing could be that these methods aren‘t in a class inheriting from NetworkBehaviour.

 

Or the script isn't on a gameobject with a spawned NetworkObject component

 

Is this a requirement? In other words, is it mandatory that all synced code or changes be attached to a spawned Network object?

EDIT: Found my answer

Yes, and the requirements for RPC methods are listed here:

Hi, I'm running into the same issues you've mentioned here (I actually posted a thread about it a few weeks ago:
https://forum.unity.com/threads/sending-serverrpcparams-on-a-buttons-onclick-method.1348490/ )

However, my buttons get instantiated and spawned dynamically and are not in-scene. Can you specify where exactly on the page you linked to did you find the answer?

Technically the buttons aren't spawned and don't have a networkobject on them but the method which is called by onClick is on a parent object which is spawned and does have a networkobject. First there is a non-networked method, which calls a serverRpc method just like you tried. Could it be that I have to get the buttons themselves to have a networkobject component as well?

 

Do you call the Rpc method directly from a button event or a script that handles button events? If so, simply add a layer of indirection:

networkedParent.SendSomeRpcMessage()

and inside that SendSomeRpcMessage which is on the networked object you‘d simply call the WhateverServerRpc method. That way any network messaging is entirely encapsulated within the network object.

 

What I've done so far is that the button calls a non-network method on the networked script, and that method calls the ServerRpc method. I'll quickly give it a try with a different script for the non-networked method.

 

This still doesn't seem to be working, I've tried to do something like this:

void OnClick()
{
parent.MethodServerRpc();
}

And it still doesn't get called, then I've tried:

void OnClick()
{
Debug.Log("trying to reach ServerRpc");
parent.Method();
}

which in the parent script is:

public void Method()
{
MethodServerRpc();
}

But again the ServerRpc doesn't get called, I do see the console log when I click the button.
Again, the parent is in a spawned NetworkObject. I do see a warning message:

"[Netcode] Deferred messages were received for a trigger of type OnSpawn with key 0, but that trigger was not received within within 1 second(s)."
Whenever I click the button though. I've yet to find an explanation for this message.

 

Having the same issue, any ideas?

 

I had the same issue, it was my NetworkObject who was not Spawned despite being a scene object and thus should be automatically spawned.
The Reason was that at the start of the NetworkManager, the object was inactivated.
All of this was done silently, no message that my rpc calls were dropped, no message that I had unspawned NetworkObject, very hard to debug.
