display nicknames of multiple clients

Hello! What's wrong? I want to display nicknames of multiple clients, but it's not working.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Networking;
3. using UnityEngine.UI;
4.  
5. public class PlayerData : NetworkBehaviour
6. {
7.     private NetworkManagerCustom NMC;
8.     public Text nicknameText;
9.     [SyncVar]
10.     private string nickname = "";
11.  
12.     void Start()
13.     {
14.         if (isLocalPlayer)
15.         {
16.             NMC = GameObject.Find("NetworkManager").GetComponent<NetworkManagerCustom>();
17.             nickname = NMC.nickname;
18.             CmdOutputNickname();
19.         }
20.     }
21.  
22.     [Command]
23.     void CmdOutputNickname()
24.     {
25.         nicknameText.text = nickname;
26.     }
27. }

 

In addition to this, you should keep in mind that SyncVar members cannot be set on the client. Your command should be setting the SyncVar on the server, and then a hook should be updating the status on the client. Something like this, essentially:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEngine.Networking;
4. using UnityEngine.UI;
5.  
6. public class PlayerData : NetworkBehaviour
7. {
8.     private NetworkManagerCustom NMC;
9.     public Text nicknameText;
10.    
11.     [SyncVar(hook="OnSyncVar_Nickname")]
12.     private string nickname = "";
13.  
14.     void OnStartLocalPlayer()
15.     {
16.         NMC = GameObject.Find("NetworkManager").GetComponent<NetworkManagerCustom>();
17.         CmdOutputNickname(NMC.nickname);
18.     }
19.  
20.     [Command]
21.     void CmdOutputNickname(string szNickname)
22.     {
23.         nickname = szNickname;
24.         nicknameText.text = nickname;
25.     }
26.    
27.     private void OnSyncVar_Nickname(string szNickname)
28.     {
29.         nickname = szNickname;
30.        
31.         if (isLocalPlayer)
32.             nicknameText.text = nickname;
33.     }
34.    
35. }
36.
