Child of main camera not following correctly

@Pema99 , You attached one script with that object (Sphere). did it effect transform? disable it and test again.

@yashpal 2 Scripts: The one on the sphere is a animation on fire2 clicked script, The one on the frist person controller has nothing to do with the ball.

Removing does nothing

Script 1:

 using UnityEngine;
 using System.Collections;
 
 public class StartAnim : $$anonymous$$onoBehaviour {
 
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetButtonDown ("Fire2")) {
             animation.Play ("hitt");
         }
     }
 }
 

Script 2:

 using UnityEngine;
 using System.Collections;
 
 public class Shoot : $$anonymous$$onoBehaviour {
 
     public Rigidbody projectile;
     public int speed;
 
     void Update () {
         if (Input.GetButtonDown ("Fire1")) {    
             Rigidbody clone;
             clone = Instantiate (projectile, transform.position, transform.rotation) as Rigidbody;
             clone.velocity = transform.TransformDirection (Vector3.forward * speed);            
             Destroy(clone.gameObject,2);
         }
     }
 }
