unable to move player due to transform.position resetting in Update()

I am trying out MLAPI in a simple 2D game (just testing the player movement rn). but i'm unable to move the object as transform.position in Update(), which is used for updating data in all the clients, is resetting the position. if i remove it, the the player in host moves but all other client players cannot.

Code (CSharp):

1. public class PlayerController : NetworkBehaviour
2.     {
3.  
4.         private Rigidbody2D _rigidbody;
5.         private float _vertical;
6.         private float _speed = 2;
7.  
8.         public NetworkVariableVector2 Position = new NetworkVariableVector2(new NetworkVariableSettings
9.         {
10.             WritePermission = NetworkVariablePermission.ServerOnly,
11.             ReadPermission = NetworkVariablePermission.Everyone
12.         });
13.  
14.         public override void NetworkStart()
15.         {
16.             _rigidbody = GetComponent<Rigidbody2D>();
17.         }
18.  
19.         /*public void Move()
20.         {
21.             if (NetworkManager.Singleton.IsServer)
22.             {
23.                 Vector2 position = transform.position;
24.                 position.y += Time.deltaTime * vertical;
25.                 _r.MovePosition(position);
26.             }
27.             else
28.             {
29.                 ChangePositionRequestServerRpc();
30.             }
31.         }*/
32.  
33.         [ServerRpc]
34.         void ChangePositionRequestServerRpc(Vector2 position, ServerRpcParams rpcParams = default)
35.         {
36.             Position.Value = position;
37.         }
38.  
39.         void Update()
40.         {
41.             //get input of local player
42.             if (IsOwner)
43.             {
44.                 _vertical = Input.GetAxis("Vertical");
45.             }
46.  
47.             //sync clients with server data
48.             //resetting values ??
49.             transform.position = Position.Value;
50.         }
51.  
52.         private void FixedUpdate()
53.         {
54.             Vector2 position = _rigidbody.position;
55.             position.y += _vertical * _speed;
56.  
57.             if (NetworkManager.Singleton.IsServer)
58.             {
59.                 _rigidbody.MovePosition(position);
60.             }
61.             else
62.             {
63.                 ChangePositionRequestServerRpc(position);
64.             }
65.         }
66.     }

how do i solve this?

 

When you move the object on the server you should still manually set the value of the NetworkVariable like this:

Code (CSharp):

1.             if (NetworkManager.Singleton.IsServer)
2.             {
3.                 _rigidbody.MovePosition(position);
4.                 Position.value = _rigidbody.Position;
5.             }

Also usually when you use rigidbodies you don't want to work with transform.position but assign the position to the rigidbody directly and do so in FixedUpdate.
