How to stop the timer ?

Hi everyone, sorry but im noob on this… How can i stop the timer when 00:00:00 occurs? because the it keeps on repeating from 01:59:00 i just want to stop the time when it comes to 00:00:00 … thanks guys :slight_smile:
here’s the script:

  using UnityEngine;
  using System.Collections;

  public class TimerScript: MonoBehaviour {

public GUIText timer;
float minutes = 1;
float seconds = 0;
float miliseconds = 0;

void Update(){

	if(miliseconds <= 0){
		if(seconds <= 0){

			seconds = 10;

		}
		else if(seconds >= 0){
			seconds--;
		}
		
		miliseconds = 100;
	}

	
	miliseconds -= Time.deltaTime * 100;

	//Debug.Log(string.Format("{0}:{1}:{2}", minutes, seconds, (int)miliseconds));
	timer.text = string.Format("{0}:{1}:{2}", minutes, seconds, (int)miliseconds);

}		 

}

Here am giving small example with 5 minutes timer…

using UnityEngine;
using System.Collections;

public class GameTimer : MonoBehaviour 
{
	public static float Game_Seconds = 59;
	public static float Game_Minutes = 4;

	void Update()
	{
		if(Game_Seconds <= 0)
		{
			Game_Seconds = 59;
			if(Game_Minutes >= 1)
			{
				Game_Minutes --;
			}
			else
			{
				Game_Minutes = 0;
				Game_Seconds = 0;
				GameObject.Find("Timer").guiText.text = Game_Minutes.ToString("f0") + ":0" + Game_Seconds.ToString("f0");
			}
		}
		else
		{
			Game_Seconds -= Time.deltaTime;
		}

		if(Game_Minutes == 0)
		{
			Application.LoadLevel ("Game_Over");
		}
		
		if(Mathf.Round(Game_Seconds)<= 9)
		{
			GameObject.Find("Timer").guiText.text = Game_Minutes.ToString("f0") + ":0" + Game_Seconds.ToString("f0");
		}
		else
		{
			GameObject.Find("Timer").guiText.text = Game_Minutes.ToString("f0") + ":" + Game_Seconds.ToString("f0");
		}
	}
}
