VeinHammer

A lightweight datapack that lets you mine entire ore veins or chop whole trees by breaking a single block. No mods required — just drop it in your world's datapacks folder.

Features

• Vein Mining — Break one ore and the entire connected vein pops. Works with all overworld ores, deepslate variants, and nether ores.
• Tree Felling — Chop one log and the whole trunk comes down. Supports all wood types including cherry, mangrove, pale oak, and nether stems.
• Enchantment Support — Fortune and Silk Touch are applied to every block in the vein automatically.
• Max Vein Size — Configurable limit (default 64 blocks) so you don't accidentally mine a whole chunk.
• Sneak-to-Activate — Optional mode where vein mining only triggers while sneaking.
• Cooldown — Configurable cooldown between vein mines (default 10 ticks).
• Fully Configurable — Add or remove blocks and tools per category (pickaxe, axe, shovel, hoe) with in-game commands.
