So pardon my ignorance, but what IS visual scripting and how does it bypass coding? I admit to being quite interested in the idea of avoiding coding, since although I can code C "fine", it's much more of a time investment to learn whatever language a game engine is in and I'm no master at coding

What do you think is the hardest thing to adapt to while in service on a sub? Also, whats one common misconception about serving aboard a sub that you see everywhere?

Thanks :)
