sdljava-users — General Discussion about sdljava and gljava

Re: [sdljava-users] New Release?

[Patric <pa...@ma...>]

Hello Ivan,

I'm glad you are back. When do you expect a new release for sdljava?

And btw, what do you think how many developers are using sdljava? Maybe you should think about making the project more public (using sourceforge newnews, other open source sites) to gain more contributors.

Best Regards,
Patric

[Ivan Z. G. <iva...@ya...>]

Greetings,

Sorry for the delay!  I finally got off my but and got everything 
working on my system so I can develop again.  Everything is 64 bit for 
now though as I didn't get a 32 chroot working yet, but alas, that will 
have to wait for another time.

I have applied the fix below to HEAD.

Cheers,

Re: [sdljava-users] Support for InputStream?

[Ivan Z. G. <iva...@ya...>]

Greetings Helge,

Currently there isn't anything like this implemented -- I'm not sure if 
reading audio is really in the scope of what SDL was intended for.  
SDL_MIxer doesn't seem to have any usefull method for reading from it.  
I don't see much of use with SDL_Sound either.

If there is a method in the C API that will do what you need then it 
could be added to sdljava.

[sdljava-users] Support for InputStream?

[Helge F. <hel...@gm...>]

Hello,

Is there anyway I can either read the byte[] array directly from the
microphone using InputStreams
from this API? I need this to be able to transmit it via UDP packages. Or do
there exists any other
way to grab a sound frame in the form of byte[] without loosing too much
time.

How much delay should I expect from such a process if it's possible?

Best regards,
Helge Fredriksen

[sdljava-users] Bug in SWIG_SetPixelData32 method / Suggestion

[Guillaume L. <le...@ho...>]

Hi,

First thanks for SDLJava. It's a great library !

There is a bug in the file SDLVideo.i (revision 1.32 from CVS HEAD)  inside 
the method  SWIG_SetPixelData32(SDL_Surface *surface, int data[]) :

   Uint32 * pixelData = (Uint32*)&data;

has to be replaced by:

   Uint32 * pixelData = (Uint32*)data;

(same thing for SWIG_GetPixelData32 method I guess...But not tested)

I need this method because I have to draw an ARGB int array in a SDL 
surface.

At First, I tried createRGBSurfaceFrom(int pixels[], ...). But JNI code 
seems not working (JVM crash)
I also tried SDLSurface.getPixelData() which returns a direct byte buffer . 
It works fine on x86 Sun JVM but not (JVM crashed) with Jamvm + Classpath 
0.92 on ARM which is my target.

A little suggestion: I think that createRGBSurfaceFrom could be easily 
implemented in Java only with help of createRGBSurface() and getPixelData() 
(or SWIG_SetPixelData32) methods.

Regards,
Guillaume Legris

[sdljava-users] Isotope Isometric Engine using sdljava

[Simon G. <sim...@al...>]

Hi all,

I've written a very easy to understand non tile based Isometric  
engine which is using your sdljava library. It was ported from a  
python and then csharp version. You can check out the code on the  
project website: http://www.webalice.it/simon.gillespie/Isotope.html

Its a simple ideal system for putting together a Knightlore or  
Cadaver on a rainy day. There a good user guide and plenty of  
comments (user guide is python centered at the moment, but if there  
is interested I'll do a java one).  Theres a full working demo and if  
it doesnt go please send me your comments and I'll see what I can do  
but it works fine for me.

Thanks for your work on the library. Very useful.

Simon.

I've tried this:

This is a Bug, right? Is there a workaround or something to fill the

Same Problem here ;(

Re: [sdljava-users] Transparent background with XGL/Compiz

[Ivan Z. G. <iva...@ya...>]

Hi Aaron,

Yes its normal.  If you want to have a color in the background use the=20
fillRect(...) methods on the SDLSurface.

For sample code have a look at the exampes included with SDLJava

[sdljava-users] Transparent background with XGL/Compiz

[<fu...@gm...>]

Hello everybody!

I use Ubuntu with installed XGL/Compiz and all the example-tests have
a transparent background, and also my own small tests. Is this normal?
And what can i do to fill the Background with a color?

I also search for a small sample code to understand sdljava.

Thanks,
Aaron

[Steve J. <jo...@gm...>]

I've got it to work, sort of, then I gave up.  It'll only work in
fullscreen mode and doesn't seem to get any input events.  My project
does run though, and other than the ungraceful exiting it looks
normal.  This all with the latest Tiger and an intel iMac.
If I have some time I'll try to get more info.

Re: [sdljava-users] Problems

[Ivan Z. G. <iva...@ya...>]

Greetings Nuno,

Everything will need to be compiled from scratch on OSX.  I don't have 
access to an OSX machine so I can't help out there.  If someone does 
manage to get it working please send me buid scripts, etc... so I could 
add it to CVS for future users.

[sdljava-users] Problems

[Nuno S. <dev...@im...>]

Hi, 

I did that. But the binaries i have are compiled for linux.

I need them compiled for osx (i think)

What i described was my problems in compiling sdljava for osx

>collect2: ld returned 1 exit status
>make: *** [libsdljava.so] Error 1

About the other problems. Yes, in part. I finally realized that maybe 
some of my problems where in handling SDL.

I think that part of my problems are derived to Directfb, because it 
sometimes hangs when getting resources like keyboard and mouse.

Is there any other way of putting SDL working without using directfb?

Many thx

Nuno Santos


Greetings Nuno,

SDLJava has not yet officially worked on OSX.  However regardless I 
think it should work but I don't have an OSX machine to verify this myself.

The error you are getting, java.lang.UnsatisfiedLinkError, is because 
the virtual machine cannot find the library.  You need to pass the 
location of the SDLJava shared library as a -D switch.

$ java -Djava.library.path=<SOME_PATH>

Give that a shot and let me know if it works!

BTW:  Did you ever resolve your earlier problems??

[sdljava-users] Problems compiling in Mac OSX

[Nuno S. <dev...@im...>]

Hi,

I'm trying to install sdljava in OSX, so i'm trying to compile from  
the scratch.

When doing that i have the following error:

MACKIE:~/Desktop/sdljava-0.9.1/src/sdljava/native lpx$ make
gcc -o libsdljava.so SDLAudio_wrap.o SDLEvent_wrap.o SDLMain_wrap.o  
SDLVideo_wrap.o SDLJoystick_wrap.o SDLCdrom_wrap.o -lSDL
/usr/bin/ld: Undefined symbols:
_main
collect2: ld returned 1 exit status
make: *** [libsdljava.so] Error 1

I also had to take an option -shared because the compiler didnt have it.

I have libsdl installed and the sdl libraries are in the place i  
think they should (it was the gentoo emerge to do it)

--- /usr/lib/
 >>> /usr/lib/libSDL-1.2.0.11.0.dylib
 >>> /usr/lib/libSDL-1.2.0.dylib -> libSDL-1.2.0.11.0.dylib
 >>> /usr/lib/libSDL.a
 >>> /usr/lib/libSDL.dylib -> libSDL-1.2.0.11.0.dylib
 >>> /usr/lib/libSDL.la
 >>> /usr/lib/libSDLmain.a

I tried to pass a manual path to linker but or i dont know how to do  
it or it doesnt work

MACKIE:~/Desktop/sdljava-0.9.1/src/sdljava/native lpx$ make
gcc -o libsdljava.so SDLAudio_wrap.o SDLEvent_wrap.o SDLMain_wrap.o  
SDLVideo_wrap.o SDLJoystick_wrap.o SDLCdrom_wrap.o -l /usr/lib/SDL
/usr/bin/ld: can't locate file for: -l/usr/lib/SDL
collect2: ld returned 1 exit status
make: *** [libsdljava.so] Error 1

The first thing i tried was to run directly and of course i had the  
following result, but i dont know what the message really means, can  
you tell me what it really says?

MACKIE:~/Desktop/IAE/Reactiva lpx$ ./corre
Native code library failed to load.
java.lang.UnsatisfiedLinkError: no sdljava in java.library.path
MACKIE:~/Desktop/IAE/Reactiva lpx$

[Ivan Z. G. <iva...@ya...>]

Really sorry this isn't working for you.  Unfortunatly I don't have a 
system up yet where I can develop.  I have not been able to compile SDL 
yet under my 32 bit chroot.  Working on it but time is scarce.  So I'm 
not able to test...

I noticed in the output your using the framebuffer device.  I never 
tested with this myself.  It should work though if SDL supports it, but, 
I never did try.

Searching on Google I found this, maybe it will help you:
    http://mail.directfb.org/pipermail/directfb-users/2005-April/000121.html

When you display the image that has strange colors is this also on the 
FB device?  Perhaps we have a problem there...

Hi Ivan,

I followed your guide line and writed a simple program in C to load a Ima=
ge.

In attach goes the program and the output.

I think i'm having real problems here because it crashes before anything
is done.

Can you see if this error is known to you?

Many thx,

Nuno

Re: [sdljava-users] SDLJava

[Ivan Z. G. <iva...@ya...>]

Hi Nuno,

Sorry that your having trouble.  I don't currently have a dev system 
setup as I just built a 64 AMD box so I will do my best.

First we need to narrow down where the problem is.  If you could try to 
load one of the picture using a straight C program that utilizes 
SDL_image we could see how it looks there.  If it looks funny in that 
case we know its something that happening with SDL.  If not the problem 
must be somewhere between sdljava and the SDL layer.

During my testing I never found that I had any problems when viewing the 
images...

Regarding OpenGL the only way it can be used is if you ask SDL to 
initialize opengl in the setVideoMode(...) call.  This will create a new 
GUI window (or fullscreen) -- so you do have to be within a graphical 
env to have opengl.

[sdljava-users] SDLJava

[Nuno S. <dev...@im...>]

Hi Ivan,

I really need you help to put the images being displayed with color!

I tought they appeared right in your initial examples but they don't  
too!

Wicked!!!

I've tried to make them files and read them then! They appear with  
strange colors as well.

And about the OpenGl... Do i need to be within a graphical enviorment  
to have opengl?

I would like to have opengl in the console with framebuffer... It's  
that possible?

If so... can you tell me a opengl sdl java aplication to test it out?  
or something that can give me sure

I really need you help to sort this image color thing

I'm working on a project based on this tecnhologie and i have to  
present it in public and i'd love make a good image

Many thx,

Nuno

[sdljava-users] Locked devices and strange solor in images

[Nuno S. <dev...@im...>]

Hi,

About the locked devices even with event it hangs the devices.

Sometimes i dont even need to run the program once. It happens in the 
first time.

About the images... i managed to create the file to the filesystem first 
and then show it. It keeps the strange colors.

How do i make disappear the mouse arrow?

Many thx

Re: [sdljava-users] How to put opengl working

[Ivan Z. G. <iva...@ya...>]

Hi Nuno,

Can you paste in some code?  How are you calling setVideoMode()?

Try to get an pure SDL OpenGL application working first.  It seems like 
OpenGL cannot be found or initialized properly on your system for some 
reason...

[sdljava-users] How to put opengl working

[Nuno S. <dev...@im...>]

Hi,

Everytime i try to initialize something with opengl content it gives me 
an error:

sdljava.SDLException: OpenGL not available
        at sdljava.video.SDLVideo.setVideoMode(SDLVideo.java:334)


I have glew installed and i dont know what to install more to get this 
working

Can anybody give me a tip on this?

Thx!

Nuno

Re: [sdljava-users] Initialization errors

[Ivan Z. G. <iva...@ya...>]

Hi Nuno,

Looks like SQL_Quit is not getting called.  Rather then killing the 
program in that way its better to look for a specific event (say ESC) 
and shutdown on that event -- doing cleanup along the way.

Let me know if that works...
