LoadScene("newscene"); GameObject Say I have a script attached to game object, and in “void Awake()” I do “DontDestroyOnLoad(GetComponent(). If you don’t use instances but rather a global This is made possible by using Don’t Destroy on Load, a function in Unity that prevents an object from being Destroyed when a new Scene is loaded, as is the default.
