How to achieve changing scenes by click in Unity 2D?show me code

To achieve changing scenes by click in Unity 2D, you can follow these steps:

1. Create a new scene in Unity and add a button to the scene.

2. Attach a script to the button to handle the click event.

3. In the script, use the SceneManager.LoadScene() method to load the new scene.

Here is an example code snippet:

using UnityEngine.SceneManagement;
using UnityEngine;

public class SceneChanger : MonoBehaviour
{
    public void ChangeScene(string sceneName)
    {
        SceneManager.LoadScene(sceneName);
    }
}

In this script, we are using the ChangeScene() method to load a new scene when the button is clicked. You can attach this script to the button and set the scene name in the button's OnClick event.
