Even the most digitally-inclined sometimes have an easier time wrapping their head around ideas on paper instead of a screen. I’m currently working through some logic with my combat system in exactly this way.
Mapping out idea, and sometimes even just writing things down helps me really get a good idea of what I want or need to do – better than typing and seeing it on the screen. It’s not a bad way to get thoughts out of your brain.
Often, I’ll jot down a URL to a page that talks about something similar to what I’m trying to do. I currently have three books. This lined book is full of notes and charts and drawing and ideas.
I have a grid/quadrille book that has database-like charts and some organized info, and I have a dot-pad book that so far has only a few layout ideas for UI.
It may seen archaic to some, and I typically prefer digital information, but hand-written notes has really helped me break through some of my issues so far in this development cycle.
