Working with MonoBehaviours

Originator classes don’t have to be straight C# classes; with a little tweaking, they can also be Unity components. The thing you have to remember is that the Memento pattern is best suited to originators that want to keep their encapsulation intact, which means you probably won’t have a ton of public variables in an originator Monobehaviour.
