Sloped belts hold their load with moving cleats (t42); sloped filters are downhill shaking screens (t43)
The magic grip is gone: cleats every 8 face cells, 6 grains tall, carry pockets uphill (about 71 grains/s against 90 flat) and overflow rolls back. Sloped filters always run downhill; grains travel by gravity and a shake, and sorting stays exact. Drawing needs another pass. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

shake; none climbs a 45° slope. So filters are flat or downhill

- **Sidewall belts with moving cleats (t42, 2026-10-26).** To replace the old full-column
|
||||
grip, use moving barrier lines rather than material cells: the barrier mask blocks normal
|
||||
powder movement without overwriting grains, terrain or parts. Cleats stand perpendicular
|
||||
to the face, spaced 8 horizontal face cells apart and 6 grains tall (integer normal reach
|
||||
4); named constants keep these tunable. A finite periodic pocket envelope carries only
|
||||
what fits, stepping every other tick. End pockets continue while the cleat rounds the band.
|
||||
Between steps no grains are stamped: bare face slides and excess rolls back. Water drains;
|
||||
bars stay level. Dark corrugated far walls sit behind visible grains; drawing uses the
|
||||
actual barrier mask, including after save/load. The envelope is a discrete transport model,
|
||||
not a calculation of contact forces. A generous flat feed delivers about 71 grains/s uphill
|
||||
versus 90 flat; accepting that reduction remains the owner's playtest decision.
|
||||
- **Inclined vibrating screens built (t43, 2026-10-26).** Diagonal filters always travel
|
||||
downhill, even when dragged uphill. R leaves a picked slope unchanged; flipping a blueprint
|
||||
mirrors its slope and keeps downhill travel. Placement and filter settings enforce the
|
||||
same direction. Sloped filters have neither column carry nor grip: gravity moves grains,
|
||||
with one mesh-contact nudge every 4 ticks (15 downhill steps/s plus gravity). Unselected
|
||||
bars step on that same cadence; selected bars fall through. Flat filters retain their
|
||||
linear transport. Sorting both slope shapes in either mode conserves the complete mix.
|
||||
Both looks use a sturdy mesh frame with a small tick-based shake only while loaded;
|
||||
idle mesh has no running belt animation. No old uphill-save migration was added.

lines (8 face cells apart, 6 grains tall), finite periodic pocket capacity and saved phase.
|
||||
Removed slope grip; natural powder movement runs between steps and surplus rolls back.
|
||||
Fixed the shared slope-to-screw mouth boundary so grains cannot fall under its casing.
|
||||
Pixel/smooth drawing uses the actual mask, continuous dark far walls, matching previews/icons.

|
||||

|
||||
same cadence. No whole-column carry or between-step grip on slopes.
|
||||
- Pixel and smooth mesh frames shake a little while loaded, with stable idle drawing.
|
||||
Updated ghosts, icons, build text, notebook and the relevant sim/UI/render files listed
|
||||
in t42 above. Added real browser drag/R/picker checks and art shake checks.
|
||||
- Both shapes and both sorting modes deliver the complete 64 sand + 64 gravel mix exactly.
|
||||
Generous-feed discharge is 60.0 grains/s down-left and 59.3 down-right; rest passes through.
|
||||
Opened shots/t43-screen-{pixel,smooth}-z{4,8}.png. Headless and smooth suites pass; the

||||
