Destroy a specific prefab (GameObject) Unity2D
Hello! I'm making a rogue-like game like "The Binding of Isaac: Rebirth". I'm making changes on the gameplay and there comes my problem. The enemies spawn randomly and they follows / shoots the player. They spawn with a script that Instantiate on a random position an enemy and makes a "Enemy(Clone)" from a prefab.
So... I want to destroy the prefab that I'm shooting with my player. I have 2 scripts, one for the bullets and other for the Enemy. When the bullet collides with an Enemy ALWAYS I destroy the first cloned GameObject instead wich I'm shooting 
I need that the GameObject destroyed will be wich 'im shooting. Here are my scripts, sorry if are bad I'm noobie yet: Enemy.cs:
public class Enemy : MonoBehaviour
{
public float enemyHelth = 100;
public void TakeDamage(float amount)
{
enemyHelth -= amount;
if (enemyHelth <= 100)
{
Die();
}
}
void Die()
{
Destroy(gameObject);
}
}
Bullet.cs :
public class Bullet : MonoBehaviour
{
public float damage = 100f; //Daño que hace la bala.
private float delayAnim = 0.3f; //Tiempo que dejamos que este activa la animación.
public GameObject hitEffect; //Sitio donde poner el efecto de impacto de la bala.
private void OnCollisionEnter2D(Collision2D collision)
{
GameObject enemyGo = GameObject.FindGameObjectWithTag("Enemy"); //Busca al enemigo mediante su etiqueta.
Enemy enemy = enemyGo.GetComponent<Enemy>(); //Busca el componente Enemy dentro del GameObject enemyGo.
if(enemy != null) //Detecta si ha encontrado a un objecto con el script Enemy.
{
enemy.TakeDamage(damage); //Hace daño al enemigo. (Ver script Enemy.cs)
}
GameObject effect = Instantiate(hitEffect, transform.position, Quaternion.identity);
Destroy(effect, delayAnim);
Destroy(gameObject);
}
}
Sorry again about the comments, my native Language is Spanish. Thank you all!
In your OnCollisionEnter, your are using GameObject.FindGameObjectWithTag, which searches all game object in other. So it will find first the enemy you instantiated first.
So should do something like this:
private void OnCollisionEnter2D(Collision2D collision)
{
GameObject enemyGo = collision.otherCollider.gameObject;
if (enemyGo.transform.tag == "Enemy")
{
Enemy enemy = enemyGo.GetComponent<Enemy>(); //Busca el componente Enemy dentro del GameObject enemyGo.
if(enemy != null) //Detecta si ha encontrado a un objecto con el script Enemy.
{
enemy.TakeDamage(damage); //Hace daño al enemigo. (Ver script Enemy.cs)
}
GameObject effect = Instantiate(hitEffect, transform.position, Quaternion.identity);
Destroy(effect, delayAnim);
Destroy(gameObject);
}
}
}

At first I didn't be able make it works with: GameObject enemyGo = collision.otherCollider.gameObject; because it didn't entered in the if statement.
So I changed seeying yours links posted above and now with this: GameObject enemyGo = collision.transform.gameObject; works like a charm!
Thank you so much!!!
