//This script moves a GameObject to a new x position using a Vector2.//Attach this script to a GameObject//Set your x position in the Inspectorusing UnityEngine;public class Examples : MonoBehaviour{    Vector2 m_NewPosition;    //This is the new X position. Set it in the Inspector.    public float m_XPosition;    // Use this for initialization    void Start()    {        //Initialise the vector        m_NewPosition = new Vector2(0.0f, 0.0f);    }    void Update()    {        //Press the space key to change the x component of the vector        if (Input.GetKeyDown(KeyCode.Space))        {            m_NewPosition.x = m_XPosition;        }        //Change the position depending on the vector        transform.position = m_NewPosition;    }}

//This script shows how a GameObject can be moved to new positions using vectors.//Attach this script to a GameObject. Click on the GameObject and the Inspector window appears.
