Hi there! I am from Russia and I've noticed a bug that some action keys doesn't work when in russian layout. I think it's rather easy to fix it.

P#1312 Posted at 2011-02-27 10:33




In Arch Linux x64 works fine. Athlon x3, Nvidia GF240, KDE 4.6.

>I've noticed a bug that some action keys doesn't work when in russian layout.

What keys do not work for you?
For me both "z" and "x" work fine in both layouts.
$ cat /etc/X11/xorg.conf.d/keyboard.conf
Section "InputClass"
    Identifier             "Keyboard Defaults"
    Option                 "XkbLayout"          "us,ru"
    Option                 "XkbOptions"         "grp:alt_shift_toggle"

p.s.: I forgot to mention a big thanks for the authors of the game. How bad I am. :)

Debian sqeeze amd64 with ia32-libs - work nice.

P#1323 Posted at 2011-02-27 12:16




The game works well. But we need to duplicate the control on the joystick. For you, it's easy to do - the game is written in the library SDL, and it works with a joystick as well as with the keyboard.

P#1324 Posted at 2011-02-27 12:32




OpenSuSE 11.3, 2.6.34, Nvidia 3D Card. It works.

P#1325 Posted at 2011-02-27 12:36




I'm a user of Fedora 13. Game just works for me, but with several problems:
1) Incompatibility with compiz. I need to launch metacity.
2) "Control" and "Alt" keys didn't work by default
3) Sometimes "up" and "left" keys are freezed after starting game.

P#1329 Posted at 2011-02-27 13:43




Ubuntu 10.10 32bit, works damn bad:
1) Left and up keys are stuck. Jasper always runs to the left.
2) Huge GNOME lags after game exit.

:: libSDL

Hello people! Regards with your effort to port the game.
However you haven't released sources yet and more, your license bounds users, as it states itself. It's why I won't run that game unless it would be distributed under the term of some libre software license like GPL or MIT license.
I hope, you will do what you have to do morally: publish entire sources for the binary to stop bounding users,
however, if you can't, you can at least do what you have to do legally: you have to publish the sources of libSDL (you can upload it separately, beside the binary package) you have used, and also mention in your license.txt, that all the restrictive terms does not apply to libSDL, which is still Free Software, released under GNU LGPL license.

I hope, once, I will be able to try out your games without breaking my moral principles and the game won't sink it ages like most of proprietary games did, but will live forever in history as Free Software games does.

PS very nice game, thanx!

6) After changing control keys in options, arrow keys are still controlling Jasper.
7) Left and up keys now are stuck at each game launch.

It's too buggy for playing...

P#1347 Posted at 2011-02-28 05:51




It works on crunchbang 10 after installing libsdl-mixer1.2 library.

P#1348 Posted at 2011-02-28 05:53




Thanks very much for all the feedback! I won't have much time to respond this week as I'm at GDC, but will try to get another build up soon to address at least some of these issues. To summarise:

I just finished writing a replacement mixer for SDL_mixer, so hopefully that will help any playback (and dependency) issues. It's extremely weird that the music should be playing too fast though.

Thanks for the tip vanfanel. I'll add an optional opengl mode in the next build.

Dual Monitor
What is a nice way to handle this? Just draw to one monitor and capture all keyboard/mouse input when in-game?

Window Size
With an opengl mode, will be able to have scalable windows. Perhaps multi-monitor mode should just be a large, frameless window covering the left side of the virtual desktop so that it lines up with the screen division? Or is that just whack?

Archive Tree Structure / .deb distribution

Key Controls
It's possible to customise the keys from the options menu, but I'll throw in some more default keys to get around the Z/W problem.
Might as well add Control/Alt too.

P#1349 Posted at 2011-02-28 06:58




Drifting / Joystick Control
Sometimes this is caused by virtualisation software using the mouse as joystick data. I found that on my Macbook the accelerometer is also used as a joystick. Next version will check for suspicious initial values to avoid this.

zzzz1 - joystick should work by default. Check log.txt to see if your joystick is identified.

Segfault Fedora 16-bit
Yikes! I'll come back to that.

Launch from directory
Fixed - will be in next build.

Big lags of GNOME after exit
Not sure if this is the same thing, but I get a pause of around 1 second when I request the program to be closed. I found this is the same for all SDL programs and seems to be related to the sound system (it doesn't happen when sound is disabled).
