MP Mode

Installing it

1. Unzip it.
2. Drop the .GOB into the episode folder of a Jedi Knight install — the one that already has JK1.GOB in it.
3. 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.

The readme that ships with it

========================================================================
 Jedi Knight Level

 P25.GOB

 A one-room MULTIPLAYER probe level. Four spawn seats, a wall of 200
 switchable panels, and a set of cogs that print what the engine thinks
 the session is: IsMulti, IsServer, GetNumPlayers, GetMaxPlayers, which
 walkplayer is yours, and whether a cog's SetWallCel is being
 replicated.

INSTALLATION
------------------------------------------------------------------------
Drop P25.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.

NOTES
------------------------------------------------------------------------
  This is the cogfactory's FIRST TYPE 2 (deathmatch) episode. In a
  stock Jedi Knight it should therefore appear in Multiplayer -> Host,
  not in the singleplayer episode list. Whether it does is the one
  thing the automated tests cannot answer.

  It prints a lot. Every readout goes to the dev console as well as
  the log; that is the point of the level.

  The panel wall repaints itself a few seconds in. Yellow is the last
  of four cels; the wall changing colour means the cogs ran.

  The other three walkplayers are spawn points, not characters. Jedi
  Knight disables every player thing but yours, so in a solo session
  they are invisible and you walk straight through them.
