Changes

Feature and fix release for Minecraft 26.3. It is still server-side only: install it on the server, and players need nothing.

Big thanks to @Skyfay (Manu), who wrote both pull requests below, including the gametests that reproduce each bug. 🙏

Fixed (#4)

Piles above an item's normal stack size reached vanilla code that never expects them. Each case below has a gametest that fails on the previous version.

  • Items were deleted when something picked up a pile. A hopper under 640 cobblestone kept 64 and deleted 576. Hopper minecarts, villagers, allays and piglins lost items the same way. Dolphins, pandas and raiders took a whole pile into a hand slot that cannot be saved above 99. Every pickup, players included, now takes one vanilla-sized stack at a time and the rest stays on the ground.
  • Logging mods such as Ledger failed on piles (Value must be within range [1;99]). Pickups now only see vanilla-sized stacks, and a freshly dropped item joins the pile around it instead of swallowing it, so the dropped entity still holds exactly what was dropped.
  • Thrown items vanished into a pile mid-air. An item you throw (Q, or a villager or piglin handing it over) now flies and lands first, and only then joins a pile.
  • A single item could pull a whole pile across the ground. The biggest pile in range now takes the others in, as vanilla does.
  • Labels froze after a restart or chunk reload, and those piles never merged again. The label is now recognised as the mod's own after loading.
  • Drops reserved for one player (target) no longer merge with public drops, or the other way round.

Added (#5)

The defaults render exactly the label you have today, so existing setups are unchanged.

  • labelFormat / timerFormat: build the label from placeholders ({count}, {stacks}, {countColor}, {timer}, {time}, {timerColor}) and & codes, including &#RRGGBB. A format without a timer no longer rebuilds the label every second, so it only sends an update when the count changes.
  • labelMode: OVERSIZED_ONLY: label a pile only once it holds more than one vanilla stack of its item (2 totems, 65 planks). Smaller piles look like vanilla drops.
  • labelThroughWalls: set to false to hide labels behind blocks. Clients using Entity Culling need minecraft:item in its entityWhitelist, see the README.

Also

  • A format with a signed hex colour such as &#-1abcd is now kept as plain text instead of being read as a colour.
  • 24 server gametests now run with every build, including a check that the hidden-label flag reaches the packets actually sent.

Upgrading

Replace the jar; no config changes are needed. Pickups of a big pile now happen one stack per touch, so collecting a very large pile takes a few touches.

Requirements

Minecraft 26.3, Fabric Loader 0.19.5+, Fabric API, Fabric Language Kotlin, and Java 25. These are unchanged from v1.2.1.
