Unity official health scripts:

This is the unity official tutorial script

using UnityEngine;
using System.Collections;

public class PlayerHealth : MonoBehaviour
{
    public float health = 100f;                         // How much health the player has left.
    public float resetAfterDeathTime = 5f;              // How much time from the player dying to the level reseting.
    public AudioClip deathClip;                         // The sound effect of the player dying.
    
    
    private Animator anim;                              // Reference to the animator component.
    private PlayerMovement playerMovement;              // Reference to the player movement script.
    private HashIDs hash;                               // Reference to the HashIDs.
    private SceneFadeInOut sceneFadeInOut;              // Reference to the SceneFadeInOut script.
    private LastPlayerSighting lastPlayerSighting;      // Reference to the LastPlayerSighting script.
    private float timer;                                // A timer for counting to the reset of the level once the player is dead.
    private bool playerDead;                            // A bool to show if the player is dead or not.
    
    
    void Awake ()
    {
        // Setting up the references.
        anim = GetComponent();
        playerMovement = GetComponent();
        hash = GameObject.FindGameObjectWithTag(Tags.gameController).GetComponent();
        sceneFadeInOut = GameObject.FindGameObjectWithTag(Tags.fader).GetComponent();
        lastPlayerSighting = GameObject.FindGameObjectWithTag(Tags.gameController).GetComponent();
    }
    
    
    void Update ()
    {
        // If health is less than or equal to 0...
        if(health <= 0f)
        {
            // ... and if the player is not yet dead...
            if(!playerDead)
                // ... call the PlayerDying function.
                PlayerDying();
            else
            {
                // Otherwise, if the player is dead, call the PlayerDead and LevelReset functions.
                PlayerDead();
                LevelReset();
            }
        }
    }
    
    
    void PlayerDying ()
    {
        // The player is now dead.
        playerDead = true;
        
        // Set the animator's dead parameter to true also.
        anim.SetBool(hash.deadBool, playerDead);
        
        // Play the dying sound effect at the player's location.
        AudioSource.PlayClipAtPoint(deathClip, transform.position);
    }
    
    
    void PlayerDead ()
    {
        // If the player is in the dying state then reset the dead parameter.
        if(anim.GetCurrentAnimatorStateInfo(0).nameHash == hash.dyingState)
            anim.SetBool(hash.deadBool, false);
        
        // Disable the movement.
        anim.SetFloat(hash.speedFloat, 0f);
        playerMovement.enabled = false;
        
        // Reset the player sighting to turn off the alarms.
        lastPlayerSighting.position = lastPlayerSighting.resetPosition;
        
        // Stop the footsteps playing.
        audio.Stop();
    }
    
    
    void LevelReset ()
    {
        // Increment the timer.
        timer += Time.deltaTime;
        
        //If the timer is greater than or equal to the time before the level resets...
        if(timer >= resetAfterDeathTime)
            // ... reset the level.
            sceneFadeInOut.EndScene();
    }
    
    
    public void TakeDamage (float amount)
    {
        // Decrement the player's health by amount.
        health -= amount;
    }
}

more unity script:

3 lives Health script:

This script show 3 lives of player, one is empty but 2 are live ,

#pragma strict

 

// Controls player health using 3 lives, 2 of which are visable

 

var fullHealth : int = 3;

var curHealth : int = 3;

var player : GameObject;

var explosion : GameObject;

var life1 : GameObject;

var life2 : GameObject;

 

function OnTriggerEnter(collider : Collider) {

    if(collider.tag == "Hazard") {

        curHealth -= 1;

    }

}

function Update () {

    if(curHealth >= fullHealth){

    curHealth = fullHealth;

}

    if(curHealth == 2){

        curHealth = 2;

        Destroy(life2);

        }

    if(curHealth == 1){

        curHealth = 1;

        Destroy(life1);

        }

    if(curHealth <= 0){

        curHealth = 0;

        Destroy(player);

            Instantiate(explosion,transform.position, transform.rotation);

        }

}

Decreasing the health:

Use this script to decrease player health, It decreases health after few seconds. have a look at this.

#pragma strict

 

//Health Textures

var health9 : Texture2D;

var health8 : Texture2D;

var health7 : Texture2D;

var health6 : Texture2D;

var health5 : Texture2D;

var health4 : Texture2D;

var health3 : Texture2D;

var health2 : Texture2D;

var health1 : Texture2D;

 

//Intigers

static var player_Health = 9.0;

 

var speed = 0.5; 

 

//Textures

var HealthGUI : GUITexture;

 

function Update()

{

   player_Health -= Time.deltaTime * speed;

   if (player_Health < 0.0)

     player_Health = 0.0;

   SetHealth();

}

 

function SetHealth() {

    switch (Mathf.RoundToInt(player_Health))

    {

         case 9:

         HealthGUI.texture = health9;

       break;

        case 8:

         HealthGUI.texture = health8;

       break;

        case 7:

         HealthGUI.texture = health7;

       break;

        case 6:

         HealthGUI.texture = health6;

       break;

       case 5:

         HealthGUI.texture = health5;

       break;

       case 4:

         HealthGUI.texture = health4;

       break;

       case 3:

         HealthGUI.texture = health3;

       break;

       case 2:

         HealthGUI.texture = health2;

       break;

       case 1:

         HealthGUI.texture = health1;

         //Don't forget to add a death script here!

       break;

    }
