Сценавание Buildindex

using UnityEngine;
using UnityEngine.SceneManagement;

// Show the buildIndex for the current script.
//
// The Build Settings window shows 5 added Scenes.  These have buildIndex values from
// 0 to 4. Each Scene has a version of this script applied.
//
// In the Project, create 5 Scenes called scene1, scene2, scene3, scene4 and scene5.
// In each Scene add an empty GameObject and attach this script to it.
//
// Each Scene randomly switches to a different Scene when the button is clicked.
