UltraMiner
UltraMiner is a Fabric game mechanics mod that mines connected blocks of the same type in one action, with configurable block groups, shapes and reach.
What it does
When a player breaks a block, UltraMiner searches the neighboring space for matching blocks that touch it on any side, edge or corner, then removes them, starting with the blocks nearest the one that was broken. The mod supports configurable block groups, so the set of blocks it treats as one vein can be chosen to suit the world.
The mining area is shaped by two settings. The square size can be set from 1x1 up to 17x17 in odd-numbered steps, and the reach can be set from 1 to 16 blocks. A reach of 1 gives a flat NxN plane, while any greater reach gives an NxN tunnel. A tunnel column stops at the first gap, so blocks behind empty spaces are not taken. The author made the mod for personal use and says anyone is welcome to use it.
UltraMiner is a client and server mod, so the server and every player need it. It is published for Fabric only, for 1.21.10 and 26.2, and the author holds all rights, so the code is not open source.
Key features
Connected block search
Blocks of the same type are found across faces, edges and corners, so diagonal ore clusters are included.
Nearest-first removal
Blocks closest to the starting block are removed first, spreading outward in the way vein mining works in other mods.
Configurable block groups
Block groups can be set so that a single break affects the blocks the player chooses to treat as one vein.
Square and tunnel shapes
The area is an NxN square of 1x1 up to 17x17 in odd steps, and a reach from 1 to 16 turns it into a plane or a tunnel.
Tunnel gap stop
A tunnel column ends at the first empty space, which keeps the mining from reaching blocks hidden behind air.
