ChainMiningg
by StarFall063
ChainMiningg, a Forge mod for Minecraft 1.12.2, extends chain mining with block previews, several shapes and selectable match modes.
What it does
When a block is broken, ChainMiningg can break the connected blocks that match it. Before the mining starts, a wireframe preview outlines every block that would be chain-mined, so the player can check the selection first. The outline color can be set in the configuration as an ARGB hexadecimal value.
The mod offers shapeless, directional and 3×3 tunnel shapes, and three match modes: meta, meta with NBT data, and registry-only matching. A hotkey combined with Shift and the mouse wheel switches shapes, and adding Ctrl switches match modes. Chunks that are not loaded are skipped during scanning, so the mod does not force them to load.
The mod is published for Forge on 1.12.2 only, with 2.3.3 as the latest file, and it runs on client and server, so both the server and every player need it. Its code is open source under the MIT License, and the source code and issue tracker are public.
