Hey Unity people. when i have one enemy in my scene, both my damage- and healthscript works fine, but when i duplicate my enemy i cant do damage to the original object.
Here is my PlayerAttackScript :

using UnityEngine;
using System.Collections.Generic;
using System.Collections;

public class PlayerAttack : MonoBehaviour {
	public int Damage = 10;					//The Players BaseDamage
	public int MeleeDamage = 10;			//The Players MeleeDamage
	public int RangedDamage = 15;			//The Players RangeDamage
	private float PlayerDistance;			//The Players Distance
	private Transform myTransform;			//The Players transform
	private Transform target;				//The Enemyes transform
	public List<GameObject> EneList;		//The Enemies List
	public GameObject prefab;
	public Transform selectTarget;
	
	void Awake(){
		myTransform = transform;	//Sets MyTransform = Players transform
		PlayerDistance = 2;			//The Distance of the players attack

	}

	void Start(){
		EneList = new List<GameObject>();
		selectTarget = null;
		AddAllEnemies();

	}
	public void AddAllEnemies(){
		GameObject[] go = GameObject.FindGameObjectsWithTag("Enemy");

		foreach(GameObject enemy in go)
			AddTarget(enemy.gameObject);
	}

	public void AddTarget(GameObject enemy){
		EneList.Add(enemy);
	}

	// Update is called once per frame
	void Update () {
		GameObject ThePlayer = GameObject.FindWithTag("Player");
		PlayerStamina PlayerStam = ThePlayer.GetComponent<PlayerStamina>();

		if(Input.GetKeyDown(KeyCode.R)){							//If R is pressed
			if(PlayerStam.StaminaE == true){						//If player has enought Stamina
				if(PlayerDistance <= 2){							//Checks that the distance is smaller than the MaxDistance
					gameObject.SendMessage("StaminaHit", 20.0f);
					GameObject.FindWithTag("Enemy").SendMessage("DamageEnemy", 20.0f);
				}
			}
		}
		GameObject go = GameObject.FindGameObjectWithTag("Enemy");						//sets the var target to a transform
		target = go.transform;															//Makes the target = the Enemys transform

		PlayerDistance = Vector3.Distance(target.position, myTransform.position);		//Checks the Enemys Distance from Player
	}
}

And this is my EnemyHealthScript :

using UnityEngine;
using System.Collections;

public class EnemyHealth : MonoBehaviour {
	public int EneHealth = 200;
	public int EneCurHealth = 200;

	void DamageEnemy (int Damage){
		GameObject TheEnemy = GameObject.FindWithTag("Enemy");
		EnemyAI EnemyAI = TheEnemy.GetComponent<EnemyAI>();
		if(EnemyAI.distance <= 2){
			EneCurHealth -= Damage;
		}
	}


	// Update is called once per frame
	private void Update () {

		if(EneCurHealth <= 0){
			EneCurHealth = 0;
		}

		if(EneCurHealth == 0){
		Destroy(gameObject);
	    }
	}
}

Thank you in Advance.

That is a bad idea to utilize tags in that manner. Your problem is caused by the fact that you have 2 objects with a Tag “Enemy” or more and you still use find single object with “Enemy” tag and it will just return the first one it finds.

You either need to always reference your EneList or utilize FindGameObjectsWithTag, though if I were you I’d completely redo this nonsense and start using “Triggers and Colliders” instead.

Furthermore I’d not even use Tags but a custom enum instead, but this one is not critical and more of a personal preference.
