I'm trying to make a chat for multiplayer, but clients messages don't update for eachother.

When a client sends a message it only updates for itself. I'm thinking that the string being sent to other clients might be empty, but I don't know how to solve it.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using TMPro;
5. using Unity.Netcode;
6.  
7.  
8. public class ChatBehaviour : NetworkBehaviour
9. {
10.     [SerializeField] private GameObject chatUI;
11.     [SerializeField] private TMP_Text chatText;
12.     [SerializeField] private TMP_InputField chatInput;
13.  
14.     private void Start()
15.     {
16.         if (IsOwner)
17.         {
18.             chatUI.SetActive(true);
19.         }
20.     }
21.  
22.     //Called from the InputField
23.     public void Send(string message)
24.     {  
25.         if (IsClient)
26.         {
27.             if (!Input.GetKeyDown(KeyCode.Return) || string.IsNullOrWhiteSpace(message))
28.             {
29.                 return;
30.             }
31.            
32.             SendMessageServerRpc(message);
33.             chatInput.text = string.Empty;
34.         }
35.     }
36.  
37.     [ServerRpc]
38.     private void SendMessageServerRpc(string message)
39.     {
40.         HandleMessageClientRpc(message);    
41.     }
42.  
43.     [ClientRpc]
44.     private void HandleMessageClientRpc(string message)
45.     {
46.         UpdateChat(message);
47.     }
48.    
49.    
50.  
51.     public void UpdateChat(string message)
52.     {
53.         chatText.text += $"\n{message}";
54.     }
55.  
56. }

 

It turns out that this only changes the text on the gameObject of the client that sent the message. The other clients can see that change but since its not on their own gameObject but rather only on the sender, their chat does not update.

 

I found a way to fix it buy making sure the clients own script is the one that is referenced.
Change the UpdateChat to this instead.

Code (CSharp):

1. public void UpdateChat(string message)
2.     {
3.         NetworkManager.Singleton.LocalClient.PlayerObject.GetComponent<ChatBehaviour>().chatText.text += $"\n{message}";
4.     }

 

thank you
