For me, the best learning process is regularly switching between learning and doing, theory and practice. The last post was research; hence, this one will be coding.
I've been a player of Role-Playing Games since I was 11. Of course, I've played Dungeons & Dragons (mainly the so-called Advanced Edition), but after a few years, I've taken upon Champions and its HERO system. The system is based on points allotment and allows virtually everything regarding a character's abilities. For a brief description of the system, please check this brilliant albeit brief Stack Exchange answer. I've developed a sample application to handle (a part of) the damage generation subsystem for this post.
