What's new

Band F — MC 1.21.11

Picks up the renames Mojang shipped at 1.21.11 that broke Band E on that version:

• net.minecraft.world.entity.vehicle.{ChestBoat,MinecartChest,MinecartHopper,AbstractMinecartContainer} → all moved into {boat,minecart} subpackages
• ResourceLocation → Identifier (renamed in place)
• ResourceKey#location() → ResourceKey#identifier()
• Level#random (field) → Level#getRandom() (method)
• CommandSourceStack#hasPermission(int) → Commands.hasPermission(Commands.LEVEL_GAMEMASTERS) predicate
• SimpleContainer#addListener removed → replaced with a DirtyContainer extends SimpleContainer that overrides setChanged() to mark the SavedData dirty

Band G — MC 26.1.2 ("Tiny Takeover")

Same rename surface as Band F, plus:

• Quarantined with its own Gradle 9.4 wrapper, Loom 1.15.5, JDK 25 toolchain. Lives under versions/26.1.2/.
• Unobfuscated — Mojang ships 26.1 without obfuscation, so no mappings loom.officialMojangMappings().
• SavedDataType first arg now Identifier (via Identifier.fromNamespaceAndPath).

Important

Band E (1.21.9) coverage narrowed. Previously claimed to cover 1.21.9–1.21.11; now claims only 1.21.9–1.21.10 since 1.21.11 requires the rename surface absorbed in Band F. If you're on 1.21.11, install the new slashlootr-0.1.1+mc1.21.11.jar.

Runtime status

• Band C (MC 1.21.1) — verified with two players on two machines
• Bands A, B, D, E, F, G — compile-clean only

Full per-band drift breakdown in docs/ARCHITECTURE.md.

v0.1.0 — Initial release

Per-player loot for naturally-generated chests, barrels, shulker boxes, and minecarts — server-side only, no client install required.

Initial release. Eight Minecraft version bands; pick the JAR that matches your server's MC version.

What's in v0.1.0

Core mechanic — Mixin cancels vanilla loot-roll so the world chest is never baked; Fabric UseBlockCallback/UseEntityCallback intercepts player right-click, builds a per-player SimpleContainer rolled from the loot table, and opens a vanilla ChestMenu/ShulkerBoxMenu/HopperMenu backed by it. The chest stays minecraft:chest forever — vanilla clients connect with no install.

Container coverage — chests, trapped chests, barrels, shulker boxes, chest minecarts, hopper minecarts, chest boats. Double chests handled (per-half persistence + combined 54-slot view).

Persistence — world/<dimension>/data/slashlootr.dat. Survives restart.

Admin & config — /slashlootr forget here|at|player and config/slashlootr.json with dimension + loot-table blocklists.

Per-band drift absorbed

Band	MC	What's special
A	1.20.1	Java 17; no RandomizableContainer/ContainerEntity interfaces — class targets + accessor mixins; pre-HolderLookup; pre-SavedData.Factory
B	1.20.5	Baseline-compatible
C	1.21, 1.21.1	Primary baseline; TBA target
D	1.21.2, 1.21.4	ContainerEntity.getLootTable() → getContainerLootTable()
E	1.21.6, 1.21.9	SavedData.Factory removed → SavedDataType + Codec rewrite

Full per-band file-level diffs in docs/ARCHITECTURE.md.

Known limitations

• No chest lid animation (open sound plays; lid stays closed)
• Hoppers don't pull from naturally-generated chests (world container is always empty by design)
• Comparator output reads 0 from naturally-generated chests for the same reason
• No runtime verification yet — compile-clean only. LocalServer test is the next thing on the list.
