accessing photon view? error CS0120: An object reference is required to access non-static member `PhotonView.isMine'

error CS0120: An object reference is required to access non-static member `PhotonView.isMine’

dont get why im getting this, trying to make my character playable only if it is mine.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class Player : Photon.MonoBehaviour {


	public float fireRate = 0.00F;
	private float nextFire = 0.1F;
	public float FireSpeed = 3F;
	public float Speed = 9;
	public float turnspeed = 50;
	public float RotateSpeed  = 50;
	public float BoostSpeed  = 12;
	public int Health = 100;
	public int SpecialUP = 0;
	public string Username;

	public Text Healthtext;
	public Text SpecialUptext;
	public Text Usernametext;

	public GameObject MachGunBullets;
	public GameObject Gunflash;
	public GameObject Camera;
	public GameObject Camera2;

	public bool ThisIsMine = false;

	   //----------------------------------------------------------------------------------------------------------------------------
	void Start(){
		if (PhotonView.isMine) {
			ThisIsMine = true;
		}
	}
		// End Start-----------------------------------------------------------------------------------------------------------------
	
	void Update ()
	{
		if (ThisIsMine = true) {
			Camera.SetActive (true);
			Camera2.SetActive (false);
			Controlable ();

		}
	}
	// End Update-----------------------------------------------------------------------------------------------------------------

	void Controlable (){

			transform.Translate (Vector3.forward * Speed * Time.deltaTime);

			if (Input.GetButton ("Fire1") && Time.time > nextFire) {
					nextFire = Time.time + fireRate * FireSpeed;
				GameObject clone = Instantiate (MachGunBullets, transform.position, transform.rotation) as GameObject;
				//gunflashed
			}

			if (Input.GetKey ("down"))
				transform.Rotate (-Vector3.right * turnspeed * Time.deltaTime);

			if (Input.GetKey ("up"))
				transform.Rotate (Vector3.right * turnspeed * Time.deltaTime);

			if (Input.GetKey ("right"))
				transform.Rotate (Vector3.up * turnspeed * Time.deltaTime);

			if (Input.GetKey ("left"))
				transform.Rotate (-Vector3.up * turnspeed * Time.deltaTime);

			// Rotate fighter
			if (Input.GetKey ("a"))
				transform.Rotate (-Vector3.forward * RotateSpeed * Time.deltaTime);

			if (Input.GetKey ("d"))
				transform.Rotate (Vector3.forward * RotateSpeed * Time.deltaTime);

			if (Input.GetKey ("w"))
				transform.Translate (Vector3.forward * BoostSpeed * Time.deltaTime);

		}
	}

Solamente cambia PhotonView.isMine por photonView.isMine
Es algún problema de la nomenclatura o algo así.
