Kobo Deluxe 0.5.0 released!---------------------------
Just six weeks after 0.4.1 - but there is reason
for the version bump: Completely remade graphics.
No more blurry scaled low-res artwork!

It's now all 24 bit graphics, drawn for 640x480
mode. (The game is still playable in 320x240
mode.) The original XKobo graphics is no longer
used, and some of the newer stuff in 0.4.1 has
been replaced (again) as well. Loading screen,
fonts, explosions, ships, bullets and other
objects - all new. Tumbling rocks, rotating big
bosses and spinning red(!) bombs. The bases are
now grouped in "areas" of ten stages, each with a
unique theme. The old "starry tiles" have become
a deep parallax starfield.

Further, there is now support for audio sample
rates up to 192 kHz, smarter scaling, optional
vsync for OpenGL, smoother animation, layered
sprites (bullets always on top), faster framework
rendering, support for OpenGL drivers enforcing
triple buffering, mouse capture and joystick
selection. The new skill levels have been tweaked
a little, and there is a "How to play" screen in
the intro. Oh, and the usual bunch of tweaks and
bug fixes, of course.

BTW, when I released 0.4.1, I actually intended
to make a few smaller 0.4.x releases, but the
plans were changed due to various events. From
now on, I'll probably have time to make smaller
releases more often - so please report any issues
ASAP!

Great game, but I’m afraid it crashes on my system. Full bactrace and
program output attached.

Keep the good work :slight_smile:

Forgot to say this is a dual core 32 bits system, with Ubuntu 7.10
installed, gcc version “4.1.3 20070929 (prerelease) (Ubuntu
4.1.2-16ubuntu2)”, and SDL 1.2.11, if it matters…

one thing i thought was a little odd with this is i tried it on quite a fresh
kubuntu install, ./configure ran through fine, then upon a make, it complained
i hadn’t installed g++, which is what i thought configure was supposed to do,
so er, dunnos… probably just me, these things only ever seem to affect me.

but dont panic david, i apt-got g++ and everthing worked fine :wink:

only thing… i did a make install and it didnt seem to appear in the k menu,
dunno if it is supposed to… tho it may have done by now as sometimes with
kubuntu some things i install only appear in the k menu after a period of time
suited by the program or kubuntu.

Thanks! Can’t seem to find anything obvious that could go wrong there,
though… Can you try running it in Valgrind and send me the output?
(Off-list preferably, as this probably has nothing to do with SDL.)

Also, compiling with -O0 instead of the default -O2 might help getting
more comprehensible output. The cfg-work script might work for that,
though it enables some non-standard config options as well.

Keep the good work :slight_smile:

Will try. :slight_smile:

Well, I would have thought the AM_PROG_CXX macro should notice if the
C++ compiler is missing, but I guess not…?

but dont panic david, i apt-got g++ and everthing worked fine :wink:

…and it even worked and didn’t blow up or anything? ;-D

Well, there are .desktop files and icons in the included icons.tar.gz,
but I haven’t written any script to install them anywhere. They’re
provided so distro maintainers have something to use for their
packages. (They were in fact submitted by distro maintainers in the
first place.)

Not quite sure how to properly detect a “compliant” desktop
environment that can use these files - or even if it’s generally
desirable for a non distro specific autotools packages to try such
things by default. Guess it can’t do any serious damage anyway…

BTW, you should be able to get around this for now by starting with
the -nosound option - though obviously, that means you get no
sound. :wink:

Would be interesting to see if there are any other issues. Never seen
this one, and I can’t think of any recent change that could cause it
(or any change at all in that area, for that matter), so I’m not sure
where to start…
