LANE8: scales that swing, bags that don't open, and fruit you can throw
The three things the greengrocer was still missing, plus the physics bug that
finding them uncovered.
HANGING SCALES. Real PinJoint3D pendulums, not animations: a static dial and
rod, and a scale-pan rigid body pinned at its own origin so it can only rotate
about the pivot. They hang at chest height down the aisles — dial at eye level,
dish below — where a real shop scale hangs and where you keep walking into it.
The dish swings 0.40 m off a light knock and the pin holds the pivot to 1.1 mm.
The pan is steel so it never breaks; what you get is a heavy brass weight loose
in a room full of stacked fruit.
THE BAG YOU CANNOT OPEN. Tearing one off the roll is the easy half — that's the
setup. Then you have to open it, and the bag has two ends, only one of which
opens, and nothing tells you which. Rubbing alternates arrow keys, because
mashing one key is not rubbing. Either the meter climbs or it doesn't, and the
only way to learn which end you're holding is to have already lost several
seconds to the other one. SPACE turns it over. That is the whole solution and
the game never says so.
CARRY AND THROW. E picks up anything under 6 kg that isn't a record; LMB throws
it at 11 m/s, six times any brittle threshold in the game. Thrown fruit bursts
on landing through the same brittle_speed path a collapse uses — no separate
thrown-object code at all.
Then the part that took the longest. Round produce got sphere colliders (a box
on an apple is why nothing ever rolled) and every display in the shop instantly
fell over. Three separate things were wrong:
- the stack radii were TYPED, not measured. The table said a cabbage was
84 mm; the model is 213 mm, so that pyramid was built with every row driven
a third of the way into the row below it. Main._glb_radius() reads the asset.
- the lattice was box geometry. For spheres the rise per row is
sqrt(4r^2 - step^2/2) — the height at which a fruit touches all four
beneath it. Anything else spawns every row above the first in mid-air.
- there was no tray. A pyramid of spheres on a bare flat table cannot stand;
nothing holds the bottom row in, so the weight above wedges it outward and
the display walks itself apart in a second. Main._stack_tray() frames each
pile in four low timber walls sized to its base row, which is what every
greengrocer on earth already does.
All 310 bodies asleep within 3 s.
While chasing that, the spawn guard fired on a cardboard box in the OFFICE. The
guard is a net, not a test: it only catches a pair Jolt happens to resolve
violently on the frames it's watching, and this one had been interpenetrating
in four levels for weeks. dev/probe_overlap.gd now finds them by measurement,
comparing every pair of dynamic colliders across all six sites. It found 15,
including a row of filing cabinets 0.70 m apart that are 0.80 m wide, and a
stapler inside a monitor. The box asset is 1.35 m across, so boxes are now
stacked into piles rather than dotted about, and the Backrooms scatter uses
rejection sampling with a 1.6 m minimum. All six sites read CLEAN.
Also: the rage veins were drawing every branch from its own start point
regardless of how far the trunk had grown, so at low rage you got disconnected
fragments floating mid-screen that read as biro scribble rather than blood. A
branch now can't appear before the trunk carrying it, and trunks are thick and
dark where capillaries are fine and pale.

LANE8: the greengrocer — soft stock, stacks that collapse, and litres
The only site whose contents are mostly SOFT, and that one material change rewrites the
level. `produce` is a new Smashable material that throws no shards at all — Splat.gd
bursts it instead: coloured pulp, a puddle that STAYS, a squelch, and litres counted,
because "how much juice did you make" is a far better score for a greengrocer than "how
many objects did you destroy".
Two knock-ons make the level play itself, both falling out of existing systems rather
than needing new ones:
* produce has a low brittle_speed, so anything heavy landing on it squashes it — which
means a pyramid crushes its OWN bottom layer as it collapses, with no special code.
Knock one off the top and the pile does the rest. Shove test: 257 items -> 45, and
42 litres of juice out of the collapse.
* puddles are slippery, cutting ACCELERATION rather than top speed so it reads as
sliding rather than as being slowed down. The more mess you make, the less the floor
cooperates.
Stacks are built bottom-up by Main._build_stack and nothing is glued or frozen — they
stand because they are stacked, so pulling one out of the bottom row does what you'd
hope. 258 produce items spawn and settle to 0.00 m/s with no spawn crush. The glass
bottles behind the juice bar are the deliberate exception: one shelf in the room that
still rewards a proper swing, and the contrast between litres and shards is the joke.
Round produce is authored CENTRED, not floor-centred like every other prop in this repo,
because a rolling body whose origin sits on the floor plane wobbles like a loaded die.
_glb_piece grew a `centred` flag for it.
REAL BUG FOUND, and it was costing hits in every level: _strike took the NEAREST collider
of any kind, so a static surface could eat a swing. Leaning over a display table, the
table edge is a few centimetres nearer than the fruit piled on it, so every swing hit the
table and nothing broke — 0/306 for the whole first take. It now prefers a Smashable and
only falls back to loose bodies if there isn't one. The offices were quietly losing hits
on desks and shelves the same way.
tools/gen_produce.py: apple, orange, tomato, watermelon, cabbage, banana hand, glass
juice bottle, display crate. The melon's stripes were radial boxes first time and it came
out looking like a sea mine; they're thin lenses through the middle now.
dev/probe_grocer.gd verifies stacks settle, that produce yields litres and NO debris,
that a collapse crushes, and that none of it leaks to the next site.
