Box Room — COG Factory

The smallest level this engine will accept: one sector, six surfaces, a spawn point. The floor grid is deliberately loud so that every later experiment can see itself.

Establishes the minimum viable JKL — and, just as usefully, exactly how the loader complains when it rejects one.

Installing it

Unzip it.
Drop the .GOB into the episode folder of a Jedi Knight install — the one that already has JK1.GOB in it.
Pick it from the episode list. On a libretro frontend, load the .GOB itself as content.

The GOB carries its own level, cogs, materials and sounds and reads the stock resource/ for everything else. There is no retail game data in the zip.

These are living projects, not finished releases. A level is rebuilt whenever something is learned — a lighting rule, a texture orientation, a whole detail pass — and it keeps its filename through all of it. The build number is how to tell which one you have: it is printed in the readme inside every zip, and it only moves when the level's bytes actually change.

 it complain when it rejects one?

  screenshot.jpg   what it looks like

INSTALLATION
------------------------------------------------------------------------
Drop P02.GOB into the `episode` folder of a Jedi Knight install (the one
that already has JK1.GOB in it) and pick it from the episode list.
Nothing else needs to change: the GOB carries its own level, cogs,
materials and sounds, and reads the stock resource/ for everything else.

On a libretro frontend, point the core at the GOB itself. It needs a
folder beside it holding `resource/` from a real install -- that is
where the retail data lives and none of it is in here.

WHAT IS IN THE GOB
------------------------------------------------------------------------
        89  episode.jk
      4928  jkl\box.jkl

      5017  bytes in 2 entries

  The readme format is styled after SM Sith Lord's cog headers,
  because his are the ones everybody read.
