Using IK to move character's hand position to pickup

Questions & Answers
1

I have a character and added a FullBodyBiped component from FinalIK. How can I move the character’s hand down to the pickup? This is what I’ve tried but it just makes the whole character float to a different position.

void PickupWeapon()
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);

            RaycastHit hit;
            Debug.DrawRay(ray.origin, ray.direction * 10, Color.red);

            if (Input.GetMouseButtonDown(0))
            {
                if (Physics.Raycast(ray, out hit,3) == true&&hit.collider.gameObject.tag=="Pickup.Weapon")
                {
                    weaponPickedup = hit.transform.gameObject;
                    //ik.solver.rightHandEffector.positionOffset = weaponPickedup.transform.position;
                    ik.solver.rightHandEffector.position = weaponPickedup.transform.position;
                    //weaponPickedup.transform.parent = domHand.transform;
                    //weaponPickedup.transform.position = domHand.transform.position;
                }
            }
        }

Figured it out. I need to use Final IK’s InteractionSystem
