game development in lisp

Name: Anonymous 2007-10-31 18:37

Is it doable? What do I use? Are there some books? Should I use a real programming language instead?

Forget it, it's NP-complete.

You use SDL like in every other faggot language.

Pretty much every text game was either written in LISP, or implemented LISP to be played. There's even a website to make a text game in LISP, but you can look that up yourself.

You typically don't do game development in quasi-functional toy languages like Lisp. What next, game development in Haskell? Gtfo.

That's just because you're not typically an expert programmer.

So, OP, is that game done yet? Since you're writing it in Lisp, I figure you could have it done by now.

There's a CL-Ncurses somewhere, but it's buggy (don't ask me how that happened). Mine aren't complete (only got the basics necessary for drawing to the screen and reading one character at a time), so they're super short. I just went through the trivial exercise of typing function definitions. Color support will probably happen at some point.

ncurses.asd:
(require 'asdf) ; This line probably only works in sbcl.

(asdf:defsystem "ncurses"
    :depends-on (cffi)
    :components ((:file "packages")
         (:file "ncurses" :depends-on ("packages"))))
packages.lisp:
(defpackage #:ncurses
  (:use #:cffi)
  (:export #:initscr
       #:start-color
       #:endwin
       #:echo
       #:noecho
       #:cbreak
       #:nocbreak
       #:keypad
       #:erase
       #:refresh

       #:addch
       #:mvaddch
       #:mvaddstr
       #:curs-set

       #:+screen-width+
       #:+screen-height+))
ncurses.lisp:
(in-package #:ncurses)

(define-foreign-library libncurses
    (:unix (:or "libncurses.so.5" "libncurses.so"))
  (t (:default "libncurses")))

(use-foreign-library libncurses)

(defctype window-ptr :pointer)
(defctype bool :int)

And here are some wrappers that remove the need for typing ncurses: before every function as well as letting you use type 'char rather than character codes. These should probably be in a package ncurses-user:, but they aren't.

(defvar *window*)

(defun init-graphics ()
  (setf *window* (ncurses:initscr))
  (ncurses:curs-set 0)
  (ncurses:start-color)
  (ncurses:noecho)
  (ncurses:cbreak))

(defun cleanup-graphics ()
  (ncurses:echo)
  (ncurses:curs-set 1)
  (ncurses:nocbreak)
  (ncurses:endwin))

(defun clear-screen ()
  (ncurses:erase))
(defun refresh-screen ()
  (ncurses:refresh))
(defun move-add-char (x y character)
  (ncurses:mvaddch y x (char-code character)))
(defun get-char ()
  (code-char (ncurses:getch)))
(defun move-add-string (x y string)
  (ncurses:echo)
  (ncurses:mvaddstr y x string)
  (ncurses:noecho))
(defun screen-width ()
  ncurses:+screen-width+)
(defun screen-height ()
  ncurses:+screen-height+)

Not in ENTERPRISE lisp. You should wrap your datastructures, thus  abstracting them in case you need them to be altered.

I recall Tim Sweeney saying something about using Haskell being good. The link was on gamedev.net (I think over a year ago now) no idea if it was archived though.

I happen to be more on the side of "no fucking way." I've not used functional languages (I've been having too much fun with embedded development) but I could imagine them being useful for rendering pipelines and physics.

I don't see why a language like Haskell wouldn't (in theory) be useful for game development. They're pretty good, although as bad as Java when it comes to being obsessive about a paradigm. Of course, in the real world a language with the "I can tell you the results but not the run time" philosophy isn't going to work out for anything but the simplest games.

Some Lisp Games
http://xach.livejournal.com/237639.html
One of the games was written by David O'Toole who has a blog dedicated to them http://lispgamesdev.blogspot.com/

Starting with the simple server in the Worms game developed in Ikarus Scheme [16], the author implemented an SDL interface and server which currently works across Chez, Gambit, Ikarus, Larceny, PLT, and Ypsilon Schemes. The use of a server process does allow for rapid porting. While simple, the C server code required considerable debugging time and the author was forced to relearn why he had forgotten the C language. (Emphasis added.)

What is it with dicks and gaem programming?

7. Conclusion
Scheme is a highly adaptable language in which to think concretely about computation. Rather than being cast in concrete, useful software architectures may be cast in jello and easily remolded. This flexibility readily allows a single author to explore a wide range of interesting computational ideas and idioms.
Lao Tze said, ”If you are one with the way, the way welcomes you” [17].
After a quarter century of use and dozens of other programming languages, the author finds that Scheme still welcomes him.
