OnServerAddPlayer SyncList not initialized

Hey,

I'm struggeling with the SyncList for some hours now.

What I am trying to accomplish: Load player items into a SyncList inside the OnServerAddPlayer before AddPlayerForConnection.

Issue: I'm getting this error on the server side

Here is the code of the uploaded minimal project.

Code (CSharp):

1. public class MyNetworkManager : NetworkManager {
2.  
3.     public GameObject StartItemPrefab;
4.  
5.     public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId) {
6.         GameObject player = (GameObject)Instantiate(this.playerPrefab, startPositions[0].transform.position, Quaternion.identity);
7.  
8.         // Load item
9.         GameObject item = Instantiate(StartItemPrefab);
10.         NetworkServer.Spawn(item);
11.  
12.         player.GetComponent<Player>().items = new SyncListUInt();
13.         // Give player the item      
14.         player.GetComponent<Player>().items.Add(item.GetComponent<NetworkIdentity>().netId.Value);
15.  
16.         NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);
17.     }
18. }

Code (CSharp):

1. public class Player : NetworkBehaviour {
2.  
3.     public SyncListUInt items = new SyncListUInt();
4.    
5.     public override void OnStartClient() {
6.         Debug.Log("Item " + items[0]);
7.     }
8. }

Thanks in advance for any help!

 

You are calling "items = new SyncListUInt();" twice (on lines 12 and 3). Try only calling it on line 3.

 

Wow, I could have sworn I already tried that. But why does this work? Do you have a clue? I mean, it sounds illogical to me that the "not initialized" error vanishes if I delete the line initializing the error throwing object.

Anyhow, thanks heaps!

 

you were overwriting items and maybe confusing it. Might want to use properties {get; private set;} to protect yourself from accidentally doing things like that.
