[ANN] Lisparuga - a 2D shoot-em-up made for the Lisp Game Jam

[ANN] Lisparuga - a 2D shoot-em-up made for the Lisp Game Jam

[Thompson, David]

Hello Guilers,

The Spring 2016 Lisp Game Jam[0] has just concluded, and I thought I
would share my entry.  It's a 2D vertical scrolling shoot-em-up game
called "Lisparuga".  Naturally, it was written completely in Guile
using the Sly game engine.  It is a free software, low-fi homage to of
one of my favorite (proprietary) games of all time: Ikaruga.  It takes
great advantage to Guile 2.1.2 for improved general performance and
specifically the unboxed floating point operations.  It's a *very*
short game, and the levels were thrown together in haste to meet the
deadline, but it's pretty challenging and novice shmup players may
need a few tries in order to beat it.

It's a bit difficult to build right now if you don't use GNU Guix, but
I hope to have a pre-built binary for 64-bit Intel systems some time
in the future.  Rough compilation instructions are available on the
above page.

All of the Lisp Game Jam entries can be found at
<https://itch.io/jam/spring-2016-lisp-game-jam/entries>, including
Christopher Webber's MUD also written in Guile, which I highly
recommend checking out.

Happy hacking!

- Dave

This is actually a really cool usage of Guix — a meta-distribution for
reproducible builds of non-packaged software.

I have guix running on Gentoo, but I had to adjust the build instructions:

guix pull # I do not know whether this was required

cd lisparuga-0.1.0
guix environment --search-paths -l guix.scm
(execute the update of the search paths by copying the lines into the shell)
./configure
make
./pre-inst-env guile game.scm


However it fails at OpenGL:

sly/window.scm:100:20: In procedure init-window:
sly/window.scm:100:20: Throw to key `sdl-error' with args `("make-gl-context" "failed to create OpenGL context: ~A" "Could not create GL context: GLXBadFBConfig")'.


Now if Guix (the build daemon setup with per-user profiles) just came
pre-packaged for all distributions… that would massively simplify
sharing in-development software.


Best wishes,
Arne

Remove --search-paths and you’re done.

Works like a charm here, smooth and everything!  :-)

Great job!

Thank you! This is the first report of the game working on another computer!
