Hello!
yes the blueprints, are where you play “connect the nodes”.
It’s not a bad learning tool to learn Unreal Engine. Is it the way to program… ummmm no, at least not in my opinion which is exactly worth what you have paid for it. NOTHING, lol But while learning Unreal Engine API, it allows you to focus on the API (because blueprinting is so simple), instead of a new environment (MSFT is new, because I like Eclipse, for every language I use, Assembler, C, etc) so you get to focus on the API (there’s really nothing to focus on in terms of learning blueprints itself, either the node exists or it doesn’t) So in that way, it’s darn good.
Anyway, have a great day!
