Legacy Animation Won't Play

Hi everyone, i'm a newbie so please help me, i'm using Legacy Animation, i added Animation Component to my Character and here is my code:

 public void damage(int dame)
     {
         playerhp = playerhp - dame;
         rb2d.AddForce (Vector2.up *400);
         gameObject.GetComponent<Animation> ().Play ("Stunt");
     
     }

when my Character being damaged it's will play that Stunt animation but it won't
