Thanks for giving it a try.  It would be very nice to add a link from the
lispbuilder page, thanks!  Soon I will need to find a real hosting service
for my game and other projects as I am currently running my own server off
of my cable modem.  Do you have any suggestions for cheap, lisp-friendly web
hosting?

Did you use Lispworks?


I am using Lispworks Pro for this project.  There really isnt anything
Lispworks specific other than the way the delivery is done.

Are the jigsaw pieces rotated in realtime, or are the

I'm pre-creating a sprite sheet with all of the pieces and their rotations.
The rotations are done in C at the moment.  Doing the rotations in Lisp was
fast enough but I was having a weird problem with performance in some
situations after the images were loaded and cached.  The game would hiccup
when dragging peices around.  The only thing I could think of that was the
GC was kicking in.   I spent a bit of time trying to figure it out but
finally took 1/2 hour to rewrite floodfill and rotate in C.  That fixed the
problem and made the game run faster so I stuck with it.


Well done!


Thanks!
