Vein Mining Continued

Runs on: Minecraft 26.3, 1.21.11, 1.21.10, 1.21.8, 1.21.5 and 1.21.4 on Fabric (Fabric API required) and on NeoForge (1.21.4 to 1.21.11). Older versions: the original Vein Mining covers 1.21.1 and below. Each file was tested with a real player mining real ore veins on a dedicated server; logs and trees were not part of those runs.

Break one block of an ore vein or a tree and every matching connected block comes down with it, with all the drops and experience gathered where you stood. The Vein Mining enchantment shows up in enchanting tables, villager trades and loot like any other, and a tool that carries it takes up to 50 connected blocks per swing; servers that prefer no enchantment set maxBlocksBase instead. Hold sneak while mining to vein mine (or pick another mode with /veinmining: always, standing or off, saved per player), and the tool and your hunger are respected block by block; each block goes through the normal break check that claim mods use, though that was not tested with a claim mod installed.

This is a continuation of Vein Mining by TheIllusiveC4 / Illusive Soulworks (LGPL-3.0-or-later, about 54 million CurseForge downloads, last released for 1.21.1), ported to the versions after it with full credit; the original author is not involved. The port is server-side only: the original's client half (key binding, activation packets, tooltips) is replaced by the sneak key and the /veinmining command, so players join with a vanilla client. The enchantment keeps its original id, so tools enchanted under the original keep working. The original licence and a notice listing every change are inside the jar; the source is in the -sources.jar next to it.

• Same walk and limits as the original: maxBlocksBase, maxBlocksPerLevel, maxDistance (new, the original hard-coded 200), diagonalMining, limitedByWorld
• Which blocks: presets (ores, ores_logs, ores_stone, ores_stone_logs, all, no_block_entities) or an allow/deny list of block IDs and tags; block groups from data packs, from the config, and built-in pairs of each ore with its deepslate form
• relocateDrops, requireCorrectTool, requiredDestroySpeed, tool damage with toolDamageMultiplier, preventToolDestruction (the vein stops before the tool breaks), hunger with exhaustionMultiplier
• /veinmining shows your mode and what your tool can do; /veinmining reload applies edits to config/veinmining/veinmining.properties
• An action-bar hint the moment a player takes an enchanted tool in hand

Compatibility: Minecraft 26.3 (Java 25) and 1.21.4 to 1.21.11 (Java 21) with Fabric Loader and Fabric API or with NeoForge; pick the file for your version and loader. Server-side: runs on dedicated servers and on the integrated server in singleplayer; other players install nothing. Licence: LGPL-3.0-or-later, continued from Vein Mining by TheIllusiveC4 with the original licence and a notice of every change in the jar.
