# Lumikins — todo

## 3D view (two arrows that swing the camera by 45 degrees) — done

Done (see AGENTS.md "The 3D view"):
- arrows at the top right + keys `[` `]` (`,` `.`, pad LT / RT), yaw -45 / 0 / +45 eased; 0 = the old 2D view, unchanged;
- `Camera3d` (perspective, turn around the middle of the view, slight tilt), clicks un-projected on the middle plane, tested;
- `TerrainMesh` + `World3d`: terrain extruded 24 px per chunk, rebuilt only where dug / built, within a time budget; cards for
  Lumikins, hatch, exit, particles, motes, glows; pools as boxes; sky and parallax far behind; HUD 2D on top;
- no GL: arrows greyed, 2D only; checked in shots (desktop Mesa) and in the browser (remote build, WebGL).

Finishing touches, done:
- the bloom shader with the 3D layer: checked on a screenshot (scene param `bloom`), nothing to fix;
- HD haze drawn in 3D; ground shadows softer, smaller, lifted;
- no dark fringes on smoothed HD cards (colours spread into the clear pixels by tools/art_hd.py, imagescale() when shrinking,
  terrain colour divided by its alpha); the 2D HD view checked, unchanged;
- backgrounds are real planes in depth (`Backdrop`), turning with the camera, no hole at +-45 degrees nor during the turn; the HD
  sky as a PNG made for GL (`*-sky-gl.png`);
- dragging at an angle follows the pointer (both points cast on the level plane);
- a Lumikin hidden by the ground gets a glowing outline instead of a faint copy.

Left / ideas:
- the outline samples a little of the neighbouring frames' pixels when a pose touches its cell's edge (none does today);
- the near layer is seen a little from the side at 45 degrees: its bottom row goes on below (a flat band) where no ground hides it.

## Other ideas
- more levels per world (now 2-3), traps, a level editor;
- hand-tuned HD frames for more poses (the HD sprites are drawn by code in tools/art_hd.py);
- Android app (bin/jumphp twa), privacy page on the site, site update for the 18 levels / 8 worlds.
