The problem with visual scripting stuff like Blox3 for example is, that it does not really help you to understand unity. It just wraps unity's way of thinking and working into something other than written out code, but it is still the same code.
It is therefor not super-helpful (imho). If you really need to go down the Unity road, the only way is to go all the way and learn it from the ground up, and if you do that, you don't need those visual things anymore. Just my personal opinion of course.
