Vector3 dir = input.normalized;
Vecotr3 vel = dir * speed * Time.deltaTime;

// 3D
transform.position = new Vector3(GameObject.Find("Object").transform.position.x, GameObject.Find("Object").transform.position.y, GameObject.Find("Object").transform.position.z);

// 2D
transform.position = new Vector2(GameObject.Find("Object").transform.position.x, GameObject.Find("Object").transform.position.y);
