Scene.name

Description

Returns the name of the Scene.

//This script changes the Scene depending on Button clicks and the Scene’s name

//To make this work, attach this script to a GameObject
//Click on the GameObject and go to the Inspector. Go to the "My First Scene" field and "My Second Scene" field and type in the name of your Scenes you would like to switch between.
//Create a Button (Create>UI>Button) and attach this in the "My Button" field of the Inspector.
//Place a Object.DontDestroyOnLoad script on your Canvas to ensure the Button isn’t deleted. You may want to add to this to remove copies on a second load.
//Make sure both of your Scenes have an EventSystem as a child of your Canvas (Create>UI>Event System).
