Add levels

You can add levels in ~/.jumpnbump/levels directory (create it if necessary). To see the added level, you have to restart jumpnbump-menu. The extension name for level is ".dat".

Create levels

There are two programs in /usr/lib/jumpnbump to help you make your own levels: pack and unpack.

/usr/lib/jumpnbump/pack -o /tmp/newlevel.dat <file1> <file2> <file3> ...
or you can just put all the files in a dir, cd to that dir and do
/usr/lib/jumpnbump/pack -o /tmp/newlevel.dat *
and it will put all the files in the current dir inside the packfile. Don't try things like pack -o stuff.dat ../file.c because it will add ../file.c as the filename in the packfile, which won't work.

/usr/lib/jumpnbump/unpack level.dat
will unpack it in the current directory.

With gobpack you can convert .gob files (which are sprites, described in /usr/share/doc/jumpnbump/gob.txt) into .pcx files which you can edit with The Gimp for example, then convert back to a .gob and use it in your own level.
/usr/lib/jumpnbump/gobpack -u font menu.pcx
will unpack font.gob using the color palette from menu.pcx and write the files font.pcx font.txt. The other gob files should use level.pcx for the correct palette.
/usr/lib/jumpnbump/gobpack font
will generate font.gob from font.pcx and the specifications in font.txt. The .pcx files should be resaved with another program, as they are not packed and are thus very large.
