Help with Enemy death Animation!

Hey I’m getting a NullReferenceException error and not sure why… Any help would be appreciated!
Thanks!

Error line :

“anim.SetBool (“Dead”, true);”

using UnityEngine;
using System.Collections;

public class EnemyHelthManager : MonoBehaviour {

public int MaxHealth;
public int CurrentHealth;
public GameObject bloodpop;
private bool Dead;
private Animator anim; 
// Use this for initialization
void Start () {
	CurrentHealth = MaxHealth;

}

// Update is called once per frame
void Update () {
	if (CurrentHealth <= 0) 
	
	{
		Dead = true;	
		anim.SetBool ("Dead", true);

	}

	if (CurrentHealth < MaxHealth)
		Instantiate (bloodpop, transform.position, transform.rotation);
}
public IEnumerator DeathAnim()

{
	if (Dead == true)
	{
	yield return new WaitForSeconds (3);
	Destroy (gameObject);
	}
}

public void HurtEnemy(int damageToGive)
{
	CurrentHealth -= damageToGive;
	GetComponent<AudioSource>().Play();
}

public void SetMaxHealth ()
{
	CurrentHealth = MaxHealth;
}

}

So I figured it out (for the 300 people following the question).

What i did was put this in the start function:

	Dead = false;

	{
		anim = GetComponent<Animator> ();
		MyRigidbody = GetComponent<Rigidbody2D> ();
	}

}

And I added this in the MonoBehaviour {

private Rigidbody2D MyRigidbody;

}

Basically i just told the script to find the Rigidbody, and use that to find the animator. At least thats how I understood it. Anyways it’s animating now but its not destroying the GameObject after the IEnumerator waits for (1) second. So If i figure that out I’ll post it or if anyone has any help with that let me know!

Thanks.
