Battle Tactics, step 1: the building blocks

These are 640×480 working frames — the HUD and the cog's own on-screen readouts are part of the picture. This project has not been re-shot yet.

Q. Can a navmesh baked from the level the engine actually loaded, checked by the engine's own stands and walks and sharpened by a person playing it, become data a vanilla COG reads inside retail's limits, so a stock enemy finds its way round walls it never learned?

Yes, in openjkdf2. In p44's outpost, trooper 1 routes 6.16 along the corridors to a wing 2.03 away through walls, and arrives in 20 s whenever the order comes. The graph is 82 nodes in eight ghost things' path frames. Withheld or scrambled, he never arrives. The mesh came from the loaded world and was checked by 40 stands and 20 real walks on every level. The design has to know two things. Stock AI sees 5 units and has no pathfinding, so a level needs to tell its enemies where to go. And AIJump crosses a 0.45 gap only from the edge. In retail JKDF2 the graph format reads back correctly; the routing has not run there.

Installing it

P64.GOB is a level. Unzip it and drop the GOB into your episode folder.
Pick it from the episode list.

The GOB carries its own level, cogs, models, and materials.

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.

  P64.GOB          the level

  screenshot.jpg   what it looks like

INSTALLATION
------------------------------------------------------------------------
Drop P64.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,
models and materials, and reads the stock resource/ for everything else.

On a libretro frontend such as RetroArch, unzip first and put P64.GOB in
the episode folder of your Jedi Knight folder, then load it from there.
The core treats the folder above the GOB's folder as the game folder,
reads the episode from episode/P64.GOB inside it, and will not start
unless that folder also holds resource/ (Res2.gob) from a real install.

CONTROLS
------------------------------------------------------------------------
  the usual Jedi Knight controls

NOTES
------------------------------------------------------------------------
  walk along the row of eight stormtrooper dummies: stand left of the
  middle and the four on the left speak, in the four text sizes; stand
  right of it and the four on the right speak, with a number and a
  name filled in at runtime and two typed (generic) messages

  every bubble turns to face you and is never mirrored, from in front,
  behind or the side; try the third-person camera too

  this is a building-blocks test level, not the Battle Tactics level
  itself

  retail JKDF2 has not run it: the bubbles are 16-bit ARGB1555
  materials on 3DO faces, which nothing here has tried in retail
  before. A screenshot from retail is the most useful thing you can
  send back

  build 5 (2026-10-03): the bubble controller now rebuilds its pool of
  cards after a game load (a death restart or a saved game). Without
  it, loading a saved game of another level pinned the player at the
  centre of the map (measured on p66's two-level episode) and bubble
  counts went wrong after a restart. Build 5 has NOT run in retail yet
