# Gravestone × Sable Compatibility Patch
A minimal patch mod for Minecraft **1.21.1 / NeoForge** that fixes gravestone
placement when a player dies on a Sable sub-level (e.g. a **Create Aeronautics**
airship). Without this mod, dying mid-flight makes gravestone place its block
(and a dirt support block) in the parent world at the player's visible position.
The blocks then clip into the airship's collision shape and stall its physics.
With this mod installed, the grave is placed inside the airship's plot area, so
it lands on the deck and travels with the airship like any other block on it.
## How it works (one paragraph)
Sable stores each sub-level's blocks in a far-away "plot" region of the same
`Level`. The visible airship position is a logical pose that's applied at render
and collision time only. Gravestone's `DeathEvents.playerDeath` calls
`GraveUtils.getGraveStoneLocation(level, deathPos)` with the player's world
position — but that position is empty space, so the search either fails or
places the grave clipping into the airship. This mod uses Mixin Extras'
`@WrapOperation` to intercept that single call and substitute the player's
position transformed into the sub-level's plot-local frame
(`subLevel.logicalPose().transformPositionInverse(playerPos)`). Gravestone's
existing search routine then finds the deck above the player's feet and places
the grave correctly inside the contraption. If the player isn't on a sub-level
when they die, the mod is a no-op.
The mod uses **Sable Companion** rather than depending on Sable directly, so
it's safe to ship in packs without Sable (the companion's default
implementation just returns null for all sub-level queries → graves behave
exactly like vanilla gravestone).
## Build
Requires **JDK 21**.
If you don't already have a Gradle wrapper jar in `gradle/wrapper/`, bootstrap
one first (one-time, needs any system Gradle ≥ 8.10 — `sdk install gradle 8.10`,
`brew install gradle`, `apt install gradle`, etc.):
```bash
gradle wrapper --gradle-version 8.10
```
Alternatively, copy `gradlew`, `gradlew.bat`, and `gradle/wrapper/` from any
recent NeoForge 1.21.1 mod template (e.g. the official
[NeoForge MDK](https://github.com/neoforged/MDK)).
Then build the mod:
```bash
./gradlew build
```
The output jar is at `build/libs/gravestone_sable_compat-1.0.0.jar`.
If the Modrinth maven can't resolve `gravestone-mod` for your machine, drop
`gravestone-1.21.1-1.0.19.jar` (or any 1.21.1 build of gravestone) into a
`libs/` folder at the project root, comment out the `compileOnly
"maven.modrinth:gravestone-mod:..."` line in `build.gradle`, and uncomment the
`compileOnly fileTree(dir: 'libs', ...)` line.
## Runtime requirements
Drop the built jar into your modpack alongside:
| Mod | Version |
|---|---|
| NeoForge | 21.1.x (1.21.1) |
| [Gravestone (henkelmax)](https://modrinth.com/mod/gravestone-mod) | 1.21.1-1.0.19 or later |
| [Sable](https://modrinth.com/mod/sable) | 1.0+ |
| [Sable Companion](https://github.com/ryanhcode/sable-companion) | 1.6+ (bundled inside this jar via JarInJar; no separate install needed) |
| Create Aeronautics | any version that uses Sable |
The mixin only attaches to `de.maxhenkel.gravestone.events.DeathEvents.playerDeath`'s
single call to `GraveUtils.getGraveStoneLocation(Level, BlockPos)`. The signature
of that call has been stable across gravestone 1.21.1-1.0.19 → 1.0.37, so the
mod should work with any of them. If a future build refactors that method, the
mixin will fail loudly at load time (`defaultRequire: 1`) rather than silently
no-op.

/**
* Compatibility patch for gravestone + Sable (used by Create Aeronautics / Eureka-style mods).
*
* <p><b>The bug:</b> Sable stores the blocks of an airship/contraption in a far-away
* "plot" region of the same {@link Level}. While the airship moves, those plot blocks
* stay put — only their visible {@link dev.ryanhcode.sable.companion.math.Pose3dc pose}
* changes. The player's world-space position reflects the airship's <i>visible</i>
* location, so when gravestone calls
* {@code GraveUtils.getGraveStoneLocation(level, deathPos)} on death, the search starts
* in empty world-space air, walks upward, and either fails or places the grave at some
* arbitrary point in the parent world. Worse, gravestone also drops a dirt block below
* the grave when the support block is replaceable — which it is in midair. The grave
* and dirt then clip into the airship's collision shape, halting its physics.</p>
*
* <p><b>The fix:</b> Just before the search, transform the player's world-space position
* back into the sub-level's plot-local frame using the inverse of its current pose.
* Pass that local position into the (unchanged) gravestone search routine. The search
* then runs entirely inside the airship's plot area; the grave lands on the deck
* (first replaceable block above the player's feet) and Sable treats it as part of
* the contraption's chunks, so it travels with the airship correctly. The dirt-support
* placement now only triggers if there's actual air below that grave inside the
* contraption, eliminating the stray world-space dirt blocks.</p>
*
* <p>If the player isn't on / riding a sub-level (vanilla death), {@code subLevel} is
* null and we just call the original method unchanged.</p>
*
* <p>We use Sable Companion's interface (which falls back to a no-op implementation
* when Sable isn't loaded) so this jar is safe to ship even in packs without Sable.</p>
*
* <p>Both {@code remap = false} flags are required because gravestone's classes are
* not in the official Mojang/Mojmap namespace (they're a third-party mod's own
* package/method names).</p>
