help for life using guiTexture

Hello im a noob/beginner programmer of C# and right now

im finding a way how to make a life using guitexture

and i found a quite useful tutorial and current using it right now

i just have a problem, i dont know , how am i supposed to make it leveltoload to my

gameOver Scene

using UnityEngine; using System.Collections;

public class Health : MonoBehaviour {

 public int startHealth;
 public int healthPerHeart;
 
 public int maxHealth;
 public int currentHealth;
 
 public Texture[] heartImages;
 public GUITexture heartGUI;
 
 private ArrayList hearts = new ArrayList();
 
 // Spacing:
 public float maxHeartsOnRow;
 private float spacingX;
 private float spacingY;
 
 
 void Start () {
     spacingX = heartGUI.pixelInset.width;
     spacingY = -heartGUI.pixelInset.height;
 
     AddHearts(startHealth/healthPerHeart);
 }
 
 public void AddHearts(int n) {
     for (int i = 0; i <n; i ++) { 
         Transform newHeart = ((GameObject)Instantiate(heartGUI.gameObject,this.transform.position,Quaternion.identity)).transform; // Creates a new heart
         newHeart.parent = transform;
         
         int y = (int)(Mathf.FloorToInt(hearts.Count / maxHeartsOnRow));
         int x = (int)(hearts.Count - y * maxHeartsOnRow);

         newHeart.GetComponent<GUITexture>().pixelInset = new Rect(x * spacingX,y * spacingY,58,58);
         newHeart.GetComponent<GUITexture>().texture = heartImages[0];
         hearts.Add(newHeart);

     }
     maxHealth += n * healthPerHeart;
     currentHealth = maxHealth;
     UpdateHearts();
 }

 
 public void modifyHealth(int amount) {
     currentHealth += amount;
     currentHealth = Mathf.Clamp(currentHealth,0,maxHealth);
     UpdateHearts();
 }

 void UpdateHearts() {
     bool restAreEmpty = false;
     int i =0;
     
     foreach (Transform heart in hearts) {
         
         if (restAreEmpty) {
             heart.guiTexture.texture = heartImages[0]; // heart is empty
         }
         else {
             i += 1; // current iteration
             if (currentHealth >= i * healthPerHeart) {
                 heart.guiTexture.texture = heartImages[heartImages.Length-1]; // health of current heart is full
             }
             else {
                 int currentHeartHealth = (int)(healthPerHeart - (healthPerHeart * i - currentHealth));
                 int healthPerImage = healthPerHeart / heartImages.Length; // how much health is there per image
                 int imageIndex = currentHeartHealth / healthPerImage;

                 
                 if (imageIndex == 0 && currentHeartHealth > 0) {
                     imageIndex = 1;
                 }

                 heart.guiTexture.texture = heartImages[imageIndex];
                 restAreEmpty = true;
             }
         }
         
     }
 }
