restart a scene to have another round

restart a scene and proceed to another round but only the score will not restart...though i have 3 rounds...and after the 3rd round it will declare now the winner..

 

You can store rounds in PlayerPrefs and just load the same scene again with Application.LoadLevel(Application.loadedLevel)

 

how to insert it here...sorry im a beginner...please help...

Code (CSharp):

1.  
2.  
3.  
4. using UnityEngine;
5. using System.Collections;
6.  
7. public class TriggerIt : MonoBehaviour {
8.     public static int scorePlayer1 = 0;
9.     public GUIText scorePlayer1Text;
10.  
11.  
12.  
13.  
14.     // Use this for initialization
15.     void OnTriggerEnter2D(Collider2D other)
16.     {
17.         scorePlayer1++;
18.         Destroy (gameObject);
19.         scorePlayer1Text.text = scorePlayer1.ToString();
20.  
21.     }
22. }
