Скачать или смотреть Changing Scenes in Unity

This Video shows how to make a scene/level change in Unity based off a collision between the object tagged as 'Player' and whatever object the code/script is attached to.

Below is the script that you can copy and paste into your own code, just remember to delete all the original code before you copy and paste this script. It is always a good idea though to type in your code manually, as this is how real programmers do it.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class SceneChanger : MonoBehaviour
{

public string targetScene;

private void OnTriggerEnter(Collider other)
{
if (other.tag == "Player")
SceneManager.LoadScene(targetScene);
}
}
