ANNOUNCE: Frag: a First Person Shooting game
Frag is a 3D First Person Shooting game. Features: *Yampa, a domain-specific embedded language for the programming of hybrid systems that using the concepts of Functional Reactive Programming (FRP) was used to program the game entities. *The Quake 3 BSP level format, Q3Map2, and the MD3 format for models and animations are used in this game. *Sven Panne's OpenGL binding, HOpenGL is used to render graphics. Requirements: HOpenGL which is provided with GHC OpenGL drivers that support the vertex array and multitexture OpenGL extensions Darcs: darcs get http://www.cse.unsw.edu.au/~pls/repos/frag Thanks goes to Don Stewart, this project would not have become public if not for him. Enjoy, Mun

This is a real cool Haskell project, and I think a lot of people will agree with me. Also, many people will wonder what problems you were faced with, how you solved them, which features you used, and so on... (see Joel Reymont's post). It might be a good idea to answer all those questions at once: write a TMR article on it ! TMR is a e-zine which provides non-academic though interesting articles on topics concerning Haskell. I think your Frag project is an ideal candidate for a TMR article. Don't worry about 'that's for smart people', the level of difficulty of the articles varies a lot (which doesn't make them less interesting). If you're interested (or someone else is, on any topic), please ask people (shapr, boegel, ...) in the #haskell channel on irc.freenode.org, mail the editor (Shae Erisson, see the wiki [http://haskell.org/tmrwiki] for more info), or just simply reply to this mail. Hope to hear from you, boegel -- Statistics are like a bikini.

This is really cool. I too would like to read a post-mortem on this project. What worked well, what didn't, etc. There aren't a lot of game engines written in Haskell so it would be interesting to see how it worked out for you. /S -- Sebastian Sylvan +46(0)736-818655 UIN: 44640862

Yes, I am really impressed, too! Finally Haskell enters the world we the real big bucks are made, e.g. Electronic Arts alone made a $3.1 billion annual revenue last year. :-)

As the developer/maintainer of the OpenGL and GLUT packages used, I would be highly interested in a post-mortem, too, especially regarding the API design, missing features, etc. Some years ago I wrote a Quake 1 level viewer (still in my old HOpenGL tar files somewhere) and one could see hickups due to GC, but this doesn't seem to be an issue anymore. Nice! Of course the next step should be using the OpenAL/ALUT packages to hear the screams of your enemies when you frag them... >:-) http://haskell.org/HOpenGL/newAPI/OpenAL/Sound-OpenAL.html http://haskell.org/HOpenGL/newAPI/ALUT/Sound-ALUT.html Cheers, S. P.S.: Some commandline options for choosing the resolution or full-screen rendering and "invert mouse" would be highly appreciated.

Thanks for releasing this! It built fine for me with ghc-6.4.1 on Fedora Core 4 x86_64, but when I run it I get: frag% ./a.out leveleg : : "loaded textures/egyptians/sand_egy.tga" "loaded textures/egyptians/leaf.tga" "loaded textures/egyptians/gold_trim02.tga" "missing texture: models/mapobjects/Skull/skull.tga" "missing texture: textures/common/trigger.tga" "loaded textures/egyptians/oldstone_ramses.tga" "missing texture: textures/sfx/hellfog.tga" *** glibc detected *** ./a.out: malloc(): memory corruption: 0x0000000000807f90 *** ======= Backtrace: ========= /lib64/libc.so.6[0x3d03d6b79e] /lib64/libc.so.6(malloc+0x7b)[0x3d03d6cb3b] ./a.out[0x58aa95] ======= Memory map: ======== : : Minimal gdb backtrace: Program received signal SIGABRT, Aborted.

A quick look into the frag sources reveals that its I/O assumes 32bit little-endian (i.e. x86-like) memory layout, so there's no surprise that it segfaults on x86-64. This should be easily fixable, I think... Mun? Cheers, S.
