Pandora [SOLVED]Trouble creating pnd for Java game

T.Willey · May 8, 2013

The final for school was a battleship game, and I thought since it could be a nice game to have on the panda I would try and pnd it up. The .jar file works fine with WizardStan's Java.pnd installed. The problem I'm having is trying to create the .pnd. I have tried in Windows 7 with PndTools, and then in Linux with the pnd_make.sh, and neither created a working file. I would preferr a linux solution, so here is my setup.

I copy the .jar, .xml, icon.png, screenshots.png, and the run.sh file into a directory. I then run the pnd_make.sh like ( the sh prefix is because its on a NTFS formated external hard-drive )

sh ./pnd_make.sh -d test -i ./test/Icon.png -x ./test/PXML.xml -p Battleshipv14.pnd -c

which reports that it made a valid pnd, but none have worked when transferred to my panda.

I have tried the suggestions from this site

http://www.pandoralive.info/?p=787

without success also.

The contents of my run.sh is

java -jar GameBattleshipPandora.jar

which works when called from my home comp.

The PXML.xml was created by PndTools.

Any help is appreciated, as its been a couple days fighting with this, and as you can see at least 14 versions of a non-working pnd. Thanks in advance. If I forgot to state anything let me know.

Please share the results of the pndout file in your /tmp folder.

That's the best thing you can do when you have an issue and want help

A couple of other things...

1. Did your run.sh get the right permissions?

2. Please share your PXML file too

3. Did you try java -jar GameBattleshipPandora.jar on the Pandora as well, from the terminal ? If it did not run there, it will never run either as a PND. That's the first thing you should check, actually. There may be libraries in the Pandora java that are not included.

T.Willey · May 8, 2013

I do not see anything pnd* in my /tmp folder. I see an output( with some numbers trailing) that I am not able to open.

1. Was not set correctly, as I cannot set it to execute on my external. Coppied to my local drive and made executable, still pnd did not work.

2.

3. The program runs on the panda, tested before I thought about making a pnd of it.

Thanks for you help.

well first does your PND appear in your Pandora menu after you put it on your SD Card? In "games"? if not you have an issue with the PXML itself.

I do not see anything pnd* in my /tmp folder.

Please share your PND here.

TrashyMG · May 8, 2013

firstly does:

java -jar GameBattleshipPandora.jar
~~work on your pandora if directly ran off the SD card and not in a PND?~~
never mind I see you did say it did..

I looked at Jcloisterzone that I did.. this is my startup script, outside of some java version detection it just runs the jar file as normal...

#!/bin/bash
if [[ "`java -version 2>&1`" =~ .*OpenJDK.* ]]
then
zenity --warning --text='OpenJDK Java Detected!!\n Oracle Java JDK Recommended for Speed and Stability.\n Check this PNDs Repo Comments for Details.' --ok-label='Continue(Unstable!)'
echo "Running Game without Oracle Java.. will be Buggy!"
fi

java -jar JCloisterZone.jar

How are you generating the PND? what tools are you making it with? the PXML looks clean to me. So I'm wondering if it's an issue of it making the image..

Does it work if you run it from command line?

pnd_run /media/YOURSDCARD/pandora/SOMEDIR/YOURPNDNAME.pndIt should output some error information.
the next thing you can do is mount the PND and try to run it from the /mnt/utmp/YOURAPPNAME directory ----**Note: pnd_run and pnd_run.sh are two separate commands.

Code:

/usr/pandora/scripts/pnd_run.sh -p YOURPNDPATH.pnd -m

To unmount:

Code:

/usr/pandora/scripts/pnd_run.sh -p YOURPNDPATH.pnd -u

he said so two posts ago

TrashyMG · May 8, 2013

Thanks, I saw that and edited it before you responded.

T.Willey · May 8, 2013

The pnd does not show anywhere in the menu. I can post the latest pnd when I get home.

I create the pnd withe the pnd_make.sh when I boot into Linux, and tried PndTools.exe when in Windows, but neither one worked. I will try to run it from the command line, and the other ways you posted TrashyMG when I get home again.

I'll post back after I've tried everything. Thanks again.

pnd_run /media/YOURSDCARD/pandora/SOMEDIR/YOURPNDNAME.pnd

It ran from the command line just fine, using the line above, and seemed to do the correct unmounting after the game was exited. Attached is the one used to test that worked from the command line.

Now I'm really stumped as to what is wrong.

The version number on the pnd is how many times I've tried to get a working pnd, not the version number of the program.

Battleshipv17.pnd

Try this ...

eject the SD card that has this PND.

go to the /mnt/utmp/ directory and see if your PND directory is still there.. If it is, try deleting it and then reinsert the SD card and see if it works.

T.Willey · May 8, 2013

The PND directory was not there. Once inserted again, the PND did not show up in any menus still.

T.Willey · May 8, 2013

Contents of the pnd_run_battleship_out file. I noticed that there is an error listed, thinking this may help.

Edit: The error appears to be a Java one, not the pnd, because I get the same error when running just the .jar from the command line.

sounds dumb, but try changing periods to underscores.. could be a quirk with the pnd system..

battleship.t.willey

to
battleship_t_willey

T.Willey · May 8, 2013

Didn't work. I even removed the './' calls, but that didn't make a difference in mounting the PND automajiclly, but I could still play the game from the command line.

Edit: I got the pnd_make.sh from here:

http://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-libraries.git;a=tree;f=testdata/scripts

How can I tell if that is the latest version? Maybe I'm using an old version of something.

This means you probably have an issue with your PXML file.

Not sure if it's the smoking gun, but it seems you have two icon tags declared..

post the pnd somewhere and I'll fix it for you

It works for me! lol

Nice waves. The game works well. I won

You spelled "carrier" wongly as "carries" in the instructions.

Are you using Oracle Java?

I also got this same message: Error parsing gtk-icon-sizes string: ''

but it works anyway.

Your problem might be only occuring on FAT32 filesystem SD cards, java is writing some font config thing, and many problems with appdata happen only on FAT32 filesystem.

I don't see why it would happen in this case, though. I'll try on a FAT SD card (shudder) and get back to you.

edit: it works on the FAT32 card also.

Were you using the newest java PND with Oracle java?

OH I SEE (maybe). It looks like you put your PND at /media/Pandora01/Java/Battleshipv17.pnd . The menu does not look in that location.

If you want it to show on the desktop and in the menu "Games -> Simulation and Strategy", put it at /media/Pandora01/pandora/apps/Battleshipv17.pnd

For the menu only, put it at /media/Pandora01/pandora/menu

TrashyMG · May 9, 2013

I totally missed what directory the PND was in... It not being in one of the Pandora specific folders will do that..
