Hello, it seems to me that the documentation is very lacking when it comes to explaining “Blackboards, Behavior Trees, Decorators, Servicess” etc. I understand there is a tutorial here (https://docs.unrealengine/latest/INT/Engine/AI/BehaviorTrees/QuickStart/index.html) but it doesnt explain fully enough why you are doing what you do. So first, I want to ask you all, how did you get to understanding those things, because I feel like the only one. Second why is his the only detailed info regarding using them? OR am I overlooking links to any topic. Thanks for your time.
I learned most of those stuff with the help of youtube tutorials + documentation and answerhub/forum articles
