Use this method if the variable to pass to the next scene is not a component, does not inherit from MonoBehaviour and is not a GameObject then make the variable to be static. Answer, Show in text certain variables This works because theyre serialised, meaning they will be visible and editable, but are, technically private, so that other scripts arent able to change them. I should have added the positives to my initial comment, as the article is indeed very informative. Require Component helps you to avoid sabotaging your own project. Get and Set functions turn a variable into a Property which, simply put, adds a layer of control over how a variable is accessed by other scripts. So, when your content is data, such as a quest or an objective, using scriptable objects to manage them can make a lot of sense. Youre welcome, Im really glad to hear its helpful. So hell yes, thank you! Attachments: You can put pretty much anything you like in a scriptable object, such as values or functions, even references to real objects in a scene, and it will work. Thanks again! To get a component from a different game object, you will first need a reference to that game object (more on how to do that later).

Unexpected uint64 behaviour 0xFFFF'FFFF'FFFF'FFFF - 1 = 0?
