Play an animation through script

Hello, I have a problem with my animation. When I want to play an animation with OnTriggerEnter2D, nothing happens. I think it has to do with the 'legacy' part of the animation, because when legacy is off, the animation shows when I do it manually, but when legacy is on, it doesn't even work manually. Here is my script: using UnityEngine; using System.Collections;

public class EnemyKill : MonoBehaviour {

 public Transform beginSpawn;
 public Transform player;
 public PlayerController Player;

 public GameObject deathParticle;
 

 // Use this for initialization
 void Start () {
     Player = FindObjectOfType<PlayerController>();
 }
 
 // Update is called once per frame
 void Update () {
 
 }

 void OnTriggerEnter2D(Collider2D other) {
     if (other.tag == "Player") {
         Player.enabled = false;
         Player.GetComponent<Renderer>().enabled = false;
         Player.GetComponent<Rigidbody2D>().velocity = Vector2.zero;
         GetComponent<Animation>().Play("EnemyKill");
         Instantiate(deathParticle, player.transform.position, player.transform.rotation);
         Invoke("Respawn", 2);
     }

 }

 public void Respawn() {
     Application.LoadLevel(Application.loadedLevel);

 }

}

Thank you for taking the time to help me.
