How can a GameObject be made persistent across scenes in Unity?

Making a GameObject persistent across scenes in Unity is accomplished by using the DontDestroyOnLoad method. This method ensures that the specified GameObject will not be destroyed when the scene is switched, allowing it to maintain its state and persist in subsequent scenes.

When you call DontDestroyOnLoad(yourGameObject), Unity marks the GameObject so that it won’t be cleared out when a new scene is loaded. This is particularly useful for elements like background music, player data, or game managers that need to retain their information across multiple scenes.

Using this method provides a straightforward solution as it is specifically designed for managing object persistence within Unity’s scene management system. Other methods, such as cloning the GameObject in each scene or re-instantiating it with a coroutine, would require additional overhead and would not retain any state or attributes that the original GameObject had, defeating the purpose of having a truly persistent object.
