     public GameObject shot;
     public Transform shotSpawn;
     public float fireRate;
      
     private float nextFire;
 
     Animator anim;

         anim = GetComponent<Animator>();
     }
 
     void Update ()
     {
         if (Input.GetButton("Fire1") && Time.time >           nextFire) 
         {
             nextFire = Time.time + fireRate;
             Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
         {

             animation.Play("PlayerRight");
 
         if (Input.GetKey(KeyCode.D))
             transform.position += new Vector3(speed + Time.deltaTime, 0.0f, 0.0f);
         if (Input.GetKey(KeyCode.A))
             transform.position -= new Vector3(speed + Time.deltaTime, 0.0f, 0.0f);
 
        
     }
 }
