Unity Multiplayer Photon Pun

Hi,
we have a problem with our controls. The Player should be controlled by using the buttons.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Photon.Pun;
5.  
6.  
7. public class Player : MonoBehaviourPunCallbacks
8. {
9.     public PhotonView view;
10.     public Rigidbody2D rb;
11.     public GameObject Players;
12.     public bool Left;
13.     public bool Right;
14.     public bool Up;
15.     public bool Down;
16.     public GameObject Bow;
17.     private int MausPos;
18.     public int PlayerAnzahl;
19.     void Start()
20.     {
21.         rb = GetComponent<Rigidbody2D> ();
22.         view = GetComponent<PhotonView> ();
23.         Players.GetComponent<PlayerAnzahl>().HowMuchPlayer++;
24.         Right = false;
25.         Up = false;
26.         Down = false;
27.         Left = false;
28.     }
29.     public void Left1()
30.     {
31.         if(view.IsMine)
32.         {
33.         Left = true;
34.         Bow.GetComponent<Bow>().Answer = true;
35.             if (Players.GetComponent<PlayerAnzahl>().possible == true)
36.             {
37.                 rb.AddForce (Vector3.left * 0.0001f);
38.                 transform.eulerAngles = new Vector3(0, 180, 0);
39.             }
40.         }
41.     }

The button activates Left1().

Thanks for help.
