Turns out you can also use Transform.root as an alternative to GetComponentInParent, it gets the topmost transform of an object hierarchy, or the target object if there's only one. It's probably going to be slightly more efficient than Get Component in Parent and is a good way to get a component from the root object if you know that's where it's going to be.

The way you explain this so clearly and concisely makes me think you put an incredible amount of work into these videos. Either that or you are a God damn genius. Well done.

This explanation of ScriptableObjects is the first one I've seen that makes any sense.

I use two approaches to managing variables:

1. A data script where I push all my major variables to (i.e. cash, progress, etc.). This is done via a Singleton from a controller script (i.e.
2. Using Game Managers to manage a set of game objects along with their respective variables (level, cost, etc).

I'm only about 6 months into learning Game Dev so going to Exploring incorporating Scriptable Objects a bit more after this video.
