how to make an object move towards another in unity

                                    transform.position = Vector3.MoveTowards(transform.position, taretPos, Qiaternion.identiy)

                                    	// the script has been edited a little but is still very similar to the original post
	public float speed;
	public GameObject object1; // The game object that moves.
	public GameObject object2; // the game object that Object 1 moves to.

	void FixedUpdate()
	{
		// Calculate direction vector.
		Vector3 dirction = object1.transform.position - object2.transform.position;

		// Normalize resultant vector to unit Vector.
		dirction = -dirction.normalized;

		// Move in the direction of the direction vector every frame.
		object1.transform.position += dirction * Time.deltaTime * speed;
	}

                                    // 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);

                                    //This will work for 2d or 3d platforms
//Make sure to call in Update or else it wont work
Vector3.MoveTowards(transform.position, taretPos, Qiaternion.identiy)

                                    Vector3 input = new Vector3 (Input.GetAxis("Horizontal"), 0 , Input.GetAxis("Vertical");
Vector3 dir = input.normalized;
Vecotr3 vel = dir * speed * Time.deltaTime;

transform.Translate(vel);
