(This will also, incidentally, be a short tutorial on lambda calculus and closures.)</p> <p>In the language of game design, Racket-MUD uses a type “entity component system,” more or less. I call it quality of things, and developed it mostly in the isolation of solitary hacking, so there are some differences.</p> <p>Everything a user interacts with inside Racket-MUD is a thing, and every thing has qualities, which define its capabilities.</p>
