shooting object from from multiple locations

hello everyone ,, I am new to unity 2d and I have been following the tutorial about angry bird style game and I wanted to edit some gameplay of the game for my own project here is my problem when we shoot the object from the catapult I want to catch the object from a different location and then shoot the object again from that location I am working on a top-down 2d game that is like that shooting the object and catches it and then shoots again. here is my code most of it is like the tutorial and I kind of ruined the editing

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class firing : MonoBehaviour {

 public float MaxStretch = 3f;
 public LineRenderer CatapultFront;
 public LineRenderer CatapultBack;
 public Transform catapult;

 private bool ClickedOn;
 private Rigidbody2D Rigid;
 private SpringJoint2D spring;
 private Ray RayToMouse;
 private Ray LeftCatapultToProjectile;
 private Vector2 PreVelocity;
 private float CircleRadius;
 private float maxS;
 private bool entering;
 
 


 private void Awake()
 {
     
     Rigid = GetComponent<Rigidbody2D>();
     spring = GetComponent<SpringJoint2D>();



 }


 void Start () {
     
     catapult = spring.connectedBody.transform;
     LineRendereSetup();
     RayToMouse = new Ray(catapult.transform.position, Vector3.zero);
     LeftCatapultToProjectile = new Ray(CatapultFront.transform.position, Vector3.zero);
         maxS = MaxStretch * MaxStretch;
     // PreVelocity = Rigid.velocity;
     CircleCollider2D circle = GetComponent<Collider2D>() as CircleCollider2D;
     CircleRadius = circle.radius;
   Rigid.gravityScale = 0.0f;

 }

 // Update is called once per frame
 void Update()

             spring.enabled = false;

             }
