Syncvar not working

[trail valley]

Syncvars only server->client

[trail valley]

Use OnStartServer

Override

Or send command from client

[Command]

If u have data on server use OnStartServer
if u have data on client use command

Idk what do u need

So u need to send data from client to server?

    public class SomeClass : NetworkBehaviour
    {
        [SyncVar(hook = nameof(HookUpdateData))]
        private string someSyncVar;

        /// <summary>
        /// CLIENT
        /// </summary>
        /// <param name="_"></param>
        /// <param name="newData"></param>
        private void HookUpdateData(string _, string newData)
        {
            // do something when client get updated `someSyncVar`
        }
        
        /// <summary>
        /// CLIENT
        /// </summary>
        public override void OnStartClient()
        {
            SomeCommandFromClientToServer("SOMEDATA");
        }

        /// <summary>
        /// SERVER
        /// </summary>
        /// <param name="data"></param>
        [Command]
        private void SomeCommandFromClientToServer(string data)
        {
            someSyncVar = data;
        }
    }

Is it what you need?

OnStartClient -> SomeCommandFromClientToServer -> HookUpdateData

You get client data in OnStartClient, then send command to server to update syncvar

Then syncvar triggers hook on clients with new data

Sorry im too sleepy to understand

If you send command from client and set syncvar to new value, yes, you could get this value with GetComponent<T>

Yes

Yes
