A lightweight Forge 1.20.1 mod that mines a 3x3 plane based on the block face you break.
Description
Overview
PlaneMiner extends the standard pickaxe behavior so that when you sneak and break a block, all matching blocks in the 3x3 plane around the hit face are broken at the same time. No configuration files, no new items — it simply works with any vanilla pickaxe.
Features
- 3x3 plane mining — breaks up to 8 additional blocks surrounding the one you destroy
- Face-based plane detection — the mining plane aligns to the face you hit (top/bottom → horizontal plane, side → vertical plane)
- Same-block filter — only blocks of the same type as the clicked block are affected
- Vanilla-compatible drops — uses the game's standard destroy logic, so Fortune, Silk Touch, Unbreaking, and XP work exactly as normal
- Safe targeting — bedrock, fluids, tile entities (chests, furnaces, etc.), and air are never affected
- No client-side dependency conflicts — no custom items, GUIs, or packets added
Requirements
| Component | Version |
|---|---|
| Minecraft | 1.20.1 |
| Forge | 47.4.0 or later (1.20.1) |
| Java | 17 |
Usage
- Hold any pickaxe in your main hand.
- Hold Shift (sneak).
- Break a block as normal.
- All matching blocks in the 3x3 plane around the hit face are destroyed simultaneously.
Example: Hit the top face of a stone block while sneaking → all stone blocks in a 3x3 horizontal grid at that Y level are mined.
