VeinMiner — a mod for Minecraft

VeinMiner — a mod for Minecraft

• Minecraft version the article was written for: 26.1.2

• Mod version: 2.7.1

• Dependencies: Fabric API, Silk, Fabric Language Kotlin 

VeinMiner breaks a connected vein of any ore or other configured blocks of the same type in a single hit — from a diamond deposit to a column of wood. The same author has two more editions of the project (a datapack for vanilla and a plugin for Paper/Purpur).

Setup 

Instead of a chat menu, there's a dedicated /veinminer command with subcommands, a file config, a permission system and block groups.

Commands 

By default everyone is granted permission to use the commands.

How to add a block to the allowed list 

By default the mod only vein-mines blocks that are on the allowed list. If a block isn't on it, it breaks one at a time, just like in plain vanilla. 
To add one, use the command: /veinminer blocks add

In a single line you can add not just one block but a whole tag — a group of blocks that Mojang has grouped by meaning in advance. For example, #minecraft:logs — all kinds of wood together.

Other vanilla tags work the same way: #minecraft:planks, #minecraft:coal_ores, #minecraft:diamond_ores, #minecraft:leaves. Some mods add their own tags in a separate namespace (for example, #c:storage_blocks from Common Tags) — those can be tied in as well.

Block groups 

Blocks from the same group break together as a single type — for example, copper_ore + deepslate_copper_ore in one group will let you break a group of connected blocks in one click. By default the config is already set up so that all ore types break together when they're connected. A single block can also belong to several groups. If no tool is set for a group, it triggers with any tool. If one is set, only with that one. 

Commands for block groups

• /veinminer groups create <name> [<block1>] [<block2>] — create a group

• /veinminer groups edit <name> add-block <block> — add a block to the group

• /veinminer groups edit <name> remove-block <block> — remove a block from the group

• /veinminer groups edit <name> add-tool <item> — restrict the group by tool

• /veinminer groups edit <name> remove-tool <item> — remove the restriction

Conclusion 

VeinMiner takes the monotonous clicking out of mining. The mod doesn't change loot, doesn't touch the balance, and doesn't require special blocks or infrastructure. That's why it suits most players. 

It works with more than just ores. If you add wood, stone or soil to the allowed list, everything connected into a single chunk of the same type breaks together. 

On the downside, on very large veins (50+ blocks at once) the client lags from the pile of simultaneous drops. mergeItemDrops helps in part: it collects everything into a single stack, but doesn't fully remove the cause.
