Question Network interaction not working / client IsOwner = false for some reason

Alright so:

Long story short, I have an interaction script, where basically "if press e, that objects runs the 'interact' method". This is currently being used for doors and whatnot, but will be expanded soon.

It is also being used to pilot around a little ship that is displayed on a screen. Currently, it works for the host, but not the client. Here is what I currently have:

Code (CSharp):

1.     public void Interact()
2.     {
3.         piloting = true;
4.         this_player = GameObject.FindWithTag("Player");
5.  
6.         Debug.Log("Is Owner = " + IsOwner);
7.     }
8.  
9.     void Update()
10.     {
11.         if (piloting == true && IsOwner == true)
12.         {
13.             this_player.GetComponent<PlayerController>().enabled = false;
14.             this_player.GetComponent<PlayerLook>().enabled = false;
15.  
16.             if (Input.GetKey("w"))
17.             {
18.                 Debug.Log("Pressing W");
19.                 ship.transform.Translate(0, 0, 10f * Time.deltaTime);
20.             }
21.             if (Input.GetKey("s"))
22.             {
23.                 ship.transform.Translate(0, 0, -10f * Time.deltaTime);
24.             }
25.  
26.             if (Input.GetKey("a"))
27.             {
28.                 ship.transform.Rotate(0, -50f * Time.deltaTime, 0);
29.             }
30.             if (Input.GetKey("d"))
31.             {
32.                 ship.transform.Rotate(0, 50f * Time.deltaTime, 0);
33.             }
34.  
35.             if (Input.GetKeyDown("e"))
36.             {
37.                 this_player.GetComponent<PlayerController>().enabled = true;
38.                 this_player.GetComponent<PlayerLook>().enabled = true;
39.                 piloting = false;
40.             }
41.         }
42.  
43.  
44.     }
45. }

The weird thing is:
only when this script runs does it say that a client isnt the owner of their machine, but it does every single other update function. If i get rid of the "If IsOwner", everything runs, W is pressed, but the ship never moves.

Everything has network interraction, variables, transforms, etc. Any ideas? Thanks in advance!

 

S***,now i meet the same problem,client `s IsOwner aways print false,i`m just a rookie by the way
