void FixedUpdate()
{
    Vector3 pos = Vector3.MoveTowards(transform.position, target.position, WalkingSpeed * Time.fixedDeltaTime);
    rig.MovePosition(pos);
    transform.LookAt(target);
}

}

simpel object switching script

public GameObject[] wepons;
int weponCounter = 0;

//By CreativeGaming.se
void Start()
{
    wepons[0].SetActive(true);
}

void Update()
{
    if (Input.GetKeyDown(KeyCode.Alpha1))
    {
        weponCounter = 0;

        for (int i = 0;i<wepons.Length;i++)
        {
             if (i != weponCounter)
                    wepons[i].SetActive(false);
             else
               wepons[i].SetActive(true);
    }
        }

    else if (Input.GetKeyDown(KeyCode.Alpha2))
    {
        weponCounter = 1;

        for (int i = 0; i < wepons.Length; i++)
        {
            if (i != weponCounter)
                wepons[i].SetActive(false);
            else
                wepons[i].SetActive(true);
        }
    }
