Here is my script:

var health:float = 100;

function Damage(dmg:float){
health -= dmg;
}

function Update (){
    if(health <=0){
        Destroy(gameObject);

    }

}

I want to display the variable of health I have on screen. Thanks for any help

The way you do this is the following - first you need to use the UI portion of Unity Engine. Do this by adding

using UnityEngine.UI;

Then, you need to create a variable of type Text - this will be the reference to your GameObject’s Text component. Lastly, you will need to edit this Text component’s text variable.

All in all, you would use something like this (in C#, sorry idk Java, but probably very similar):

using System.Collections;
using UnityEngine;
using UnityEngine.UI;

public class YourScriptName : MonoBehaviour
{
        public Text textbox;

	    void Start()
        {
                textbox = GetComponent<Text>();
        }

        void Update()
        {
                textbox.text = "" + health;

                if(health <= 0)
                Destroy(gameObject);
        }
}

This is, of course, assuming that your text box is a child of the object this script is attached to. If it isn’t you can either remove the Start function and add it in the editor by hand, or you can use FindObjectOfType, which I wouldn’t recommend for Text.
