Third Party Mirror Networking error

Hi everybody, I have this problem with my code. When I enter if(GetComponent<NetworkIdentity>().isLocalPlayer) in the console it says, "The type or namespace name 'NetworkIdentity' could not be found (are you missing a using directive or an assembly reference?)" I have a NetworkIdentity on my player but the error still occurs.

 

Here is my code:

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.Networking;
3.  
4. public class PlayerSetUp : MonoBehaviour
5. {
6.  
7.     Behaviour[] componentsToDisable;
8.  
9.     void Start()
10.     {
11.         if(GetComponent<NetworkIdentity>().isLocalPlayer)
12.         {
13.             for (int i = 0; i < componentsToDisable.Length; i++)
14.             {
15.                 componentsToDisable[i].enabled = false;
16.             }
17.         }
18.     }

 

Sorry, Just realized that you can just put using Mirror; under using UnityEngine; Hope I have saved others the trouble
