如何通过光子统一网络发送同步脚本

我有一个多人游戏，它使用手电筒，如果我按下L，另一个游戏的手电筒也会关闭，但当batteryTimeLeft达到20时，它只在本地游戏上闪烁。

我如何将整个脚本与所有用户同步，以便闪烁也能通过网络传播？

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class LightManager : Photon.MonoBehaviour {
    public GameObject flashlight;
    public Light lightinflashlight;
    public bool Lightenabled = true;
    public float batteryTimeLeft = 100f;
    public float batteryDrainRate;
    public float minIntensity = 0.25f;
    public float maxIntensity = 8f;
    public bool flashlightRanOut = false;
    float random;
    float noise;
    public float time=3;
    void start(){
        PhotonView photonView = this.photonView;
        lightinflashlight = GetComponentInChildren<Light> ();
    }
    void Update () {
        photonView.RPC("publicUpdate", PhotonTargets.All); 
    }
    void FixedUpdate() {
        photonView.RPC("publicFixedUpdate", PhotonTargets.All); 
    }

    public void publicFixedUpdate(){
        batteryTimeLeft -= batteryDrainRate;
        if (time < 0) {
            time = 0;
        } 
        time--;
    }
    [PunRPC]
    public void publicUpdate(){
        if (batteryTimeLeft >= 20) {
            flashlight.GetComponent<Light> ().intensity = 8;
            flashlightRanOut = false;
        }
        if (batteryTimeLeft < 0) {
            batteryTimeLeft = 0;
            flashlightRanOut=true;
        }
        if (!flashlightRanOut) {
            if (batteryTimeLeft <= 20) {
                if (time > 1) {
                    random = Random.Range (0.0f, 150.0f);
                    noise = Mathf.PerlinNoise (random, Time.time);
                    flashlight.GetComponent<Light> ().intensity = Mathf.Lerp (minIntensity, maxIntensity, noise);
                }
            }
            if (time < 0) {
                time = 3;
            }
            if (Input.GetKeyDown (KeyCode.L)) {
                Lightenabled = ! Lightenabled;
            }
            flashlight.SetActive (Lightenabled);
        } else {
            flashlight.SetActive (false);
        }
    }
}
