How can I fix my attack animation?

Hello! I trying to figure out how I can fix my attack animation. My walking / idle & jump animation is working.

But when I try attack nothing happends.

My code:

using UnityEngine; using UnityEngine.UI; using System.Collections;

public class PlayerSettings : MonoBehaviour { Rigidbody rigid; // Player Movement public float moveSpeed; public float maxSpeed; public float jumpSpeed; bool isJumping = true;

 // Attacking
 public int damage = 10;
 public float range = 2f;
 bool isAttack = true;


 // Coins
 public int coinsGain;
 public Text coinsText;

 // Animations
 public Animation anim;
 public AnimationClip runAnimation;
 public AnimationClip idleAnimation;
 public AnimationClip jumpAnimation;
 public AnimationClip swordAnimation;

 void Start () 
 {
     rigid = GetComponent<Rigidbody> ();
     anim = GetComponent<Animation> ();
 }

 void Update() 
 {
     //Attacking
     Attacking();

     // Animations
     InitAnimations ();

 }

 void FixedUpdate () 
 {
     // Movement
     Movement ();
     // Jumping
     Jumping();
 }

 void InitAnimations() 

{ // When jumping the Run/idle animation stops. if (isJumping) { // Run & Idle start. if (rigid.velocity.magnitude > 0.3f) { anim.CrossFade (runAnimation.name); } else { anim.CrossFade (idleAnimation.name); } } }

 void Attacking() 
 {
     if (Input.GetKeyDown (KeyCode.Mouse0) && isAttack) 
     {
         anim.CrossFade (swordAnimation.name);
         Debug.Log ("Swing");
     } 
         
 }

 void Movement() 
 {
     float moveHori = Input.GetAxis ("Horizontal");
     rigid.AddForce (Vector3.left * moveSpeed * moveHori);

     if (rigid.velocity.magnitude > maxSpeed) 
     {
         rigid.velocity = rigid.velocity.normalized * maxSpeed;
     }

     if (Input.GetAxis("Horizontal") == -1f) 
     {
         Quaternion rightRotation = Quaternion.Euler (0, 90, 0);
         transform.rotation = rightRotation;
     }

     if (Input.GetAxis("Horizontal") == 1f) 
     {
         Quaternion leftRotation = Quaternion.Euler (0, -90, 0);
         transform.rotation = leftRotation;
     }
 }

 void Jumping()
 {
     if (Input.GetKeyDown (KeyCode.Space) && isJumping) 
     {
         rigid.velocity = rigid.velocity + Vector3.up * jumpSpeed * Time.deltaTime;
         anim.CrossFade (jumpAnimation.name);
     }
 }

 // Collecting the Coins.
 void OnTriggerEnter(Collider col) 
 {
     if (GameObject.FindGameObjectWithTag ("Coins")) 
     {
         coinsGain += 1;
         coinsText.text = coinsGain.ToString ();
         GetComponent<AudioSource> ().Play ();
     }

 }

 void OnCollisionEnter(Collision colEnter) 
 {
     isJumping = true;
 }

 void OnCollisionExit(Collision colExit) 
 {

         isJumping = false;
 }

}
