New Developer Needing guidance

here’s my problem (any why it’s so frustrating) - I’ve been programming a long time, so all the programming concepts like class inheritance, persistence, variable types etc etc etc is old hat to me, but i am a super novice at unreal. Because I have a background in design, i picked up the modelling and scene building, materials, etc really easily. What’s killing me is the implementation of the logic and coding. I watch the tutorials on blueprints, i see the basic ideas, but for example the simple act of limiting characters only travelling in one direction - i know it’s likely super simple but i don’t even know where to start to tackle it. So thats why i was looking for an ultra noob tutorial series that said for example “ok, now we want our actor to do X, and to do that we add this node, then connect it like this, and etc.” Most of the tutorials i see assume you have more knowledge than that.
