Countdown

IbrahimA

I did this script and it works fine but there is a problem, when I enter room it works fine and countdown works, but when someone else enters the room it counts down again, I want when a player enters, the camera is placed on the player who was already in the room.
sorry for my english

(CSharp):
   private Text TimeUIText;
    private float timeToStartRace = 5.0f;
    private void Awake()
    {
        TimeUIText = DeathMatchGameController.instance.TimeUIText;
    }
    // Start is called before the first frame update
    void Start()
    {
    }
    // Update is called once per frame
    void Update()
    {
        if (PhotonNetwork.IsMasterClient)
        {
            if (timeToStartRace >= 0.0f)
            {
                timeToStartRace -= Time.deltaTime;
                photonView.RPC("SetTime", RpcTarget.AllBuffered, timeToStartRace);
            }
            else if (timeToStartRace < 0.0f)
            {
                photonView.RPC("StartTheRace", RpcTarget.AllBuffered);
            }
        }
    }

    public void SetTime(float time)
    {
        if (time > 0.0f)
        {
            TimeUIText.text = time.ToString("F0");
        }
        else
        {
            //The countdown is over
            TimeUIText.text = "";
        }
    }
    [PunRPC]
    public void StartTheRace()
    {
        GetComponent<CarUserControl>().enabled = true;
        this.enabled = false;
    }
