Q$4(20$p$).$ What does the following script do$?$ Script is attached to an active cube game object located on a plane.

using UnityEngine;

public class Test : MonoBehaviour$\{$

float rSpeed$=5f$;

Vector$3$ dir $=$ Vector$3.$zero;

float mSpeed $=2f$;

void Update$()\{$

if $($Input$.$GetKey$($KeyCode$.$Mouse$0))\{$

Ray ray $=$ Camera.main.ScreenPointToRay$($Input$.$mousePosition$)$;

RaycastHit hit;

if $($Physics$.$Raycast$($ray$.$origin, ray.direction, out hit$))$

dir $=$ hit.point;

transform.position $=$ Vector$3.$Lerp$($cube$.$position, hit.point, mSpeed $*$ Time.deltaTime$)$;

Quaternion rot $=$ Quaternion$().$SetLookRotation$($dir$)$;

transform.rotation $=$ Quaternion.Lerp$($cube$.$rotation, rot, rSpeed $*$ Time.deltaTime$)$;

$\}\}\}$
