Slabbed 0.2.0-beta.4
Slabbed 0.2.0-beta.4 is a major interaction-stability update for slab-supported building.
This release focuses on making common objects sit, target, and interact more consistently on slab-supported structures. A lot of previously cursed behavior around hitboxes, outlines, targeting, floating objects, and server/client disagreement has been improved.
This is still a beta. It does not claim universal support for every Minecraft block or item category yet.
Highlights
- Major targeting and hitbox improvements for slab-supported objects.
- Better visual contact for many objects placed on lowered slab-supported structures.
- Improved server-side validation for lowered trapdoors and regular doors.
- Fixed several cases where the client selected the correct visible object but the server rejected or snapped the interaction back.
- Improved fence, wall, fence gate, chain, lantern, button, trapdoor, and door behavior around lowered slab structures.
- Added large proof coverage for common slab-supported object families.
- Added release-readiness audits and jar/classpath checks for the beta.4 release candidate.
Object targeting and hitbox improvements
Beta 4 includes a large pass on visible-object ownership and hitbox targeting.
Improved behavior includes:
- Crosshair targeting more reliably selects the visible object instead of the slab/support block underneath.
- Visible objects on lowered slab-supported structures now hold ownership more consistently.
- Hitboxes, outlines, raycasts, and visual placement feel are better aligned across many supported object categories.
- Several “I can see the object, but Minecraft thinks I’m clicking something else” cases were fixed.
This affects many common building objects, including:
- Torches
- Candles
- Flower pots
- Buttons
- Trapdoors
- Regular doors
- Chains
- Lanterns
- Fences
- Walls
- Fence gates
- Stairs in audited slab-supported setups
- Ordinary blocks in audited slab-supported setups
Trapdoors and doors
Trapdoors and regular doors received major stability fixes.
Trapdoors
- Fixed lowered trapdoors being targetable but not staying open.
- Fixed server-side shifted validation for lowered trapdoor interactions.
- Fixed cases where trapdoors would appear to open and then snap closed.
- Improved trapdoor targeting around slab-supported structures.
Regular doors
- Fixed regular doors losing target ownership to the support slab underneath.
- Fixed upper/lower door-half interaction instability.
- Fixed cases where one half of a lowered door would interact correctly while the other half blinked, failed, or snapped back.
- Added paired-door interaction proof so upper and lower halves stay consistent.
Buttons
- Fixed floor buttons visually floating above certain lowered slab-supported surfaces.
- Improved button contact alignment.
- Improved button hit acceptance in slab-height interaction cases.
- Server-side validation now handles supported lowered button targets more consistently.
Fences, walls, and fence gates
Fences, walls, and fence gates received a large visual/contact/targeting pass.
Improvements include:
- Better contact with visible support surfaces.
- Fixed cases where walls/fences floated or sat at the wrong height.
- Improved stacked fence/wall behavior.
- Improved visual hitbox and stack-aim behavior.
- Preserved tall collision where appropriate while aligning visual selection and targeting with the visible object.
- Fixed server-side interaction issues for supported lowered fence/wall contexts.
Chains and lanterns
- Improved chain target ownership and visible interaction behavior.
- Improved chain behavior in slab-supported hitbox/targeting contexts.
- Lanterns are included in the audited SBSBS top-visible-support matrix.
- Chain axis metrics remain internally tracked, but chain visible-owner behavior is much more stable.
Torches, candles, and flower pots
Beta 4 includes major fixes for small floor-supported objects.
Torches
- Improved floor torch placement on lowered slab-supported structures.
- Fixed visual contact issues where torches appeared to float or sit at the wrong level.
- Improved torch targeting and placement acceptance in supported slab contexts.
Candles
- Improved candle floor/top contact on slab-supported surfaces.
- Fixed contact gaps in audited supported cases.
Flower pots
- Improved flower pot placement, contact, and survival behavior.
- Added survival checks so flower pots remain only when genuinely supported.
Common object compatibility
Several common full-block or object-like cases received contact, triad, or compatibility work.
Audited or improved object families include:
- Chests
- Barrels
- Furnaces
- Bookshelves
- Crafting tables
- Enchanting tables
- Stonecutters
- Grindstones
- Anvils
- Fences and walls
- Fence gates
- Doors and trapdoors
This does not mean every block-like object in Minecraft or every modded object is fully supported yet. It means these common categories received focused stabilization and proof coverage.
SBSBS / stacked slab-supported structure audit
Beta 4 includes a focused SBSBS held-item acceptance audit.
The audited top-visible-support matrix passed for:
- Stone
- Stone slab
- Stone stairs
- Birch trapdoor
- Spruce door
- Acacia button
- Torch
- Candle
- Flower pot
- Iron chain
- Oak fence
- Cobblestone wall
- Oak fence gate
- Lantern
The audit found no reproduced release-blocking RED rows for that tested top-visible-support structure.
Not covered by that matrix:
- Glass panes / panes
- White carpet / carpets / thin top layers
This means Beta 4 improves many common SBSBS-style interactions, but it does not claim universal support for every possible side-face, against-face, or thin-layer case.
Slab lane and placement behavior
Beta 4 includes many fixes around lowered slab-supported placement and targeting.
Improvements include:
- Better handling of lowered slab-supported visible targets.
- Improved placement inheritance in audited lowered slab-lane cases.
- Better preservation of visible object ownership before slab/support rescue logic steals the target.
- Improved server/client agreement for shifted interactions.
Known limitation:
Some slab placement or break neighbor updates can still visually re-resolve lowered slab lanes in specific stacked builds. This is tracked as:
