Making the item system polymorphic was ultimately a mistake, but that was a big one. Q: Why was this was a mistake? A: When you declare a class that’s a kind of item, it locks you into that structure much more tightly than if you just have member elements. It’s nice to be able to use virtual functions and that kind of thing, but the tradeoffs are just too much. I started using a “tool” item in the hierarchy, which st…

"Tool" is still a class, with perhaps very generic polymorphic methods (e.g. do_default_action() ). The problem is not polymorphism per se, but rather about having a deep class hierarchy aka lasagna code. My policy: OOP is like salt. Use little and that's great. I only allow a single inheritance layer, and ideally no inheritance at all.

IMO that's one of the best ways a single programmer can spend his career. No weird requirements, no deadlines, no nothing, nada. Just one's passion and a product. Whether it is successful is irrelevant. Kudos Mr. Adams for making the achievement and moves gaming history. Going back to the interview, I found this line (and the logic attached) interesting: >Making the item system polymorphic was ultimately a mistake, b…

Everything about it is wonderful (I really mean that) except the fact that he's sponging off his mother to do it. I can't help but feel that it's a drop of vinegar that spoils the whole cup of milk

I have a passion for programming but I need something to drive me. I'm useless when I try and make stuff on my own. But if I've got someone telling me "I need a system that does X", I just get highly motivated in delivering it. Like I need requirements.

Damn you sound exactly like me...when I work for my own projects they usually die off quickly once I figure out how to do it (without actually implementing it but I'm pretty sure it can be implemented in this or that way). But if it comes from a friend, or a colleague then I'm super focused on it until it's done. It's almost as if I do projects to show off to other people or I like to serve other people.

Do you actually play it? I'm a bit the same about reading about it, yet I have never once played it for myself!

Hah, this is like EVE Online for me. I love reading about the espionage and cloak and dagger and pure insanity, but other than a brief toe-dip...oh no I will not play it. DF lives in my blood, however.
