remove health from 1 gameobject at a time

Hello,

i have made a health script that reduces the health when the object gets hit by a raycast. The script works for 1 gameibject per scene, but i want to be able to use it for multiple gameobjects (targets, enemies etc).

These are the scripts i have:

The raycastgun:

using UnityEngine;
using System.Collections;

public class GunHit
{
	public float damage;
	public RaycastHit raycastHit;
}

public class RaycastGun : MonoBehaviour 
	{
	public float fireDelay = 0.1f;
	public float damage;
	public string buttonName = "Fire1";
	public LayerMask layerMask = -1;


	private bool readyToFire = true;



	// Use this for initialization
	void Start () {
	}
	
	// Update is called once per frame
	void Update () 
	{
		if (Input.GetButtonDown (buttonName) && readyToFire) 
		{
			RaycastHit hit;
			if (Physics.Raycast (transform.position, transform.forward,out hit, Mathf.Infinity,layerMask))
			{
				//Health verlagen wanneer 
				Health.currentHealth = Health.currentHealth - damage;
				Debug.Log (Health.currentHealth);
			}
		}
	}
}

and the health:

using UnityEngine;
using System.Collections;

public class Health : MonoBehaviour {

	public float maxHealth = 100.0f;
	static public float currentHealth = 100.0f;

	// Use this for initialization
	void Start () 
	{
		currentHealth = maxHealth;	
	}

	void Update ()
	{
		if (currentHealth <= 0) 
		{
			gameObject.SetActive(false);
		}
	}
}

thanks,

You currentHealth variable is static, so there can be only one value ever of it. Remove the static keyword to be able to have a value per-instance.
