[Jsokoban-gamedevel] Change in PropertyConstants

[Gustavo F. B. <gf...@bb...>]

Matthias:

        I've  seen  the  changes that you did to the PropertyConstants
        File, and i've seen that you used URLUtils. In my opinion that
        change has two drawbacks:

        -  For  the  non  JWS  version you need the JWS library, or it
        won't compile ( i used the JNLP jar lib that is much smaller)

        -  The  .getClass.getRosource  method  resolves the path using
        the  Classpath,  and  File uses the path of java.exe, so could
        produce some problems, if it not launched from a batch file

        I  will upload a version of MainFrame with a menu for changing
        the LookAndFeel in a couple of minutes

        
 Regrets

[Jsokoban-gamedevel] New stuff

[Matthias J. <mat...@te...>]

hi

Here now some new stuff for the game.

1. I will implement a help system for our game, where we describe the game rules and also some howto's for level, images and so on
2. I want change the Levelset file type from many files to one zip-file
   This need changes in the Levelset class and a change of the LoadLevelset operation in the ui. Weshould change it so that you can install a new levelset in the level dircetory, then the levelset is added in the menu.
Also you can remove the levelset with this new gui.
This help us to add new levelsets to the application. also we can so put new levelsets on our homepage and the user can install them easy.

3. Add a support for the other look and feel of java 
4. add mouse support for the game ( move the player with the mouse )
5. redesign the level finished message ( own class ) with support for showing the moves, pushes and the time for the future.
Also support for showing the levelname the level number and the levelsetname.
6. A disign installer ( game graphics ) like the levelset installer
7. Show Levelsetname, levelnumber in the game panel


What do you think about this??

[Matthias J. <mat...@te...>]

hi

can you also remove the broken pictures and add it as binary.

i lost the original version from the pictures.

also you can release the directories we don't longer use in the cvs.

[Jsokoban-gamedevel] Issues on restart

[Gustavo F. B. <gf...@bb...>]

Matthias:

   I was looking at the loadlevel bug, and it was a issue on the
   restart of the level. (if you restart the level, then it will say
   that the level is completed on the first move).
   I attach the files with the changes, if you agree with the changes
   i will commit them.

   What do you think if we release the empty directories on the CVS
   tree?
   
Greetings
  Fede

[Jsokoban-gamedevel] Exception on StartUp

[Gustavo F. B. <gf...@bb...>]

Matthias:

   The error that causes the exception, is the splash image corrupted
   in the CVS repository. That's because the file isn't defined as a
   binary file. I don't know if that could be changed, or if the file
   must be deleted and added again.

   I will work on the loadlevel bug

[Jsokoban-gamedevel] Re: Java Web Start

[Matthias J. <m....@gm...>]

hi

1. webstart:

what do you think if we implement all features for you implement in the 
ws version
that work also in the standard version..

and for the other thinks we create a own branch in the cvs.

at which version you want to start with the ws version??? is 0.2beta2 
possible you think?

2. next release 0.2beta2

it is possible to you to check in all your changes until the 30. April ??

then we shoult test the application. 1 week is enought i think.
and report all bug in the bug system at soureforge

and after that we have 2 weeks to fix the bugs we found.

3. i have added you to the project
so now can use the cvs and commit your canges ...


nice day
matthias

hi

sorry.. i had a computer crash *MicroS...*
and lost all my data....

so can you please send me your last mails .... :)

i  will add you at sourceforge to the project. Then you can check in 
your own code changes :-)
you done a very good work and i would like to thank you and hope it will 
continue :)


So please also add a feature u like to have in the freature request and 
bugs you find in the bug tracker.
:-)

thanks
Matthias

[Jsokoban-gamedevel] JSokoban - Java Web Start almost done

[Gustavo F. B. <gf...@fu...>]

texx:

I was able to make jsokoban run under java web start. Attached is a zip
file with the source, and the html and the jnlp files.(To run it add
jdom.jar and xerces.jar to the dist folder)

I do a LOT of changes to the source, in special, to the properties,
images, level and levelset load code.

I still need to rewrite the loadlevel and loadlevelset functions (JWS
uses another class for opening files).

The code that i send you works in both versions of jsoko (jws and
non-jws), but the loadlevel part will need some special code.

I send you two emails before of this, if you don't read them, tell me,
and i will send it again.

Greetings
  Federico

[Jsokoban-gamedevel] webstart and other stuff

[Matthias J. <M....@gm...>]

hi

thanks that you take a look at webstart.

i have include your files in my code and now i test it.

on sunday i think i will commit it in the cvs with  a few other changes (
about box,...)

I think a redesign of the web page would be great. with a integration of the
news system  and the forum from sourceforge.
also an idear for the weppage is a hiscore list. :-)
maybe you know a webdesigner :-)

also i release a new version on sunday ( jsokoba0.2beta2 ).

i have add a few tasks to the tasklist of the game at sourceforge. and if
you find a bug in the game please add it to the buglist :-)

bye 
matthias

Re: [Jsokoban-gamedevel] Load Level

[Matthias J. <M....@gm...>]

hi.

sorry i write so late back. (got a lot of work)

i think thats a good solution for this problem.

i'm working now on some problems with the about box ( license panel ).

to the package: 

i also want to put it in the ui.util package but i forgot it before i check
it in *g*


i found another thing we should do.
if you load a big level and the window of jsokoban is to small you don't get
scroll bars. 
that must be fixed.  ( i add it to the bug list today or tomorrow )

[Jsokoban-gamedevel] =?iso-8859-1?Q?Load_Level?=

[<gf...@bb...>]

Hi:

I'm trying to do the load level stuff, and i found a possible problem.

In GamePanel.java , in the methods jbinit, nextlevel, and lastlevel you do 
this:

m_lLevel.setFilePath(PropertyConstants.Level_Path); 

this forces the level to be in the default level directory. 
Then, if i want to load a level in other directory, this overrides the 
directory that i set.
The solution that i think is to set de default path in the Level 
constructor, so it could be overrided. 
What do you think?

bye!


PS: I saw that you added to the CVS repository the files that i send. 
I think that the file LevelFileFilter.java should be in the package 
jsokoban.ui.util, not in the base.util , because it is only used with the 
JFileChooser dialog

Re: [Jsokoban-gamedevel] TextLevelSet

[Matthias J. <M....@gm...>]

I think it would we good tomake the program compatible to the these
levelsets.
So a user can download one and use it.

in the moment he must write a xml file and put every level in a own level
file. I think nobody would do that.

The only think i don't know in the moment is if we schould "kill" the
xml-levelset and change the program that we only use the text-levelset.
What do you think?

[Jsokoban-gamedevel] TextLevelSet

[Gustavo F. B. <gf...@bb...>]

Hi:

I have seen that kind of levelsets in other programs, and i have a =
question.=20
Do you want make a compatible file or a proprietary one?

Changing the subject, the code seems ok to me.
The only thing that i look is in XMLReaderWriter. If I try to open a =
levelset using an absolute path (in windows), jdom throws a FileNotFound =
Exception,=20
so, i change a little the parse method and the problems dissapear.

public static Document parse(String sFilename) throws =
org.jdom.JDOMException
  {
      SAXBuilder saxbuilder =3D new SAXBuilder();
      saxbuilder.setValidation(XML_VALIDATION);
      return saxbuilder.build(new File(sFilename));
  }

[Jsokoban-gamedevel] Textlevelset & other stuff

[Matthias J. <M....@gm...>]

hi

the textlevelset:

this is a textfile which include a set of level in on file. the most sokoban
programs i found in the net use a sot of this file, so it might be a good
idear to include this in this program.

the problem is that many different "versions" exists of this levelsset
filetype.

thats the reason why i use xml files.

example see www.sokomind.de

code:

what do you think about the existig code and package structure etc.?
