Seamstrike
Vein mining on a key you choose: hold it and one swing takes the whole seam, with tool wear, enchantments and hunger still counting.

About this project
What does Seamstrike add?
Seamstrike
Vein mining on a key you choose: an outlined selection, six shapes on the mouse wheel, and hoes, shovels and axes that work the whole selection.
What it does
- Hold the Seamstrike key (` by default) and mine one block: every connected block of the same kind comes with it, up to 64. Any block: ore, stone, logs, leaves, gravel, crops.
- The selection is outlined in the world before you swing, with the block count and the shape name beside the crosshair.
- Nine shapes, picked with the mouse wheel while the key is held: Shapeless (the whole seam), Small Tunnel (1x1), Walking Tunnel (1x2), Small Square (3x3), Large Square (5x5), Large Tunnel (3x3 deep), Mining Tunnel (stairs down), Escape Tunnel (stairs up) and Corridor (3x2).
- Right-click works too: a hoe tills, a shovel makes paths and an axe strips the whole selection. With Sowback installed, one right-click on any plant of a field, ripe or not, harvests and replants every ripe one.
- Nothing is free: the tool wears per block and stops before it breaks, Fortune and Silk Touch apply, hunger drains. Ore needs the right pickaxe.
- The drops go straight into your inventory, and what does not fit lands at your feet; the experience flies to you. The key is in Controls; limits are in
config/seamstrike.json. - Tree felling, no key needed: an axe on a log of a real tree takes the whole tree and its leaves, and a sapling goes back in the ground. Log houses are safe (no natural leaves), and sneaking chops one log. Steps aside when FallingTree is installed.
- An eighth shape, Walking Tunnel: one wide, two high, straight in.
- A ninth shape, Corridor: three wide, two high, straight in.
- Ore in the walls: a tunnel, square or staircase also takes every ore vein it uncovers, within maxBlocks. oreInWalls in config/seamstrike.json.
- Lava guard: tunnels, squares and veins leave every block that holds back lava, so a cut never floods you. lavaGuard in config/seamstrike.json.
- Clear roof: tunnels, squares and staircases also take the sand and gravel resting on them, so the roof never pours in.
- Water guard: a cut also leaves blocks that hold back water, when you start on dry rock (
waterGuardin config/seamstrike.json). - Huge fungi: an axe on a crimson or warped stem fells the whole fungus, its wart blocks and shroomlight too, and the fungus goes back in the ground.
- More kinds in one: sand and red sand are one kind for tunnels and squares, and so is every colour of terracotta.
- Ice and wool: tunnels, squares and staircases treat any ice as one kind and any wool as one kind.
Needs
- Minecraft 26.3, 1.21.11 or 1.21.1 with Fabric Loader + Fabric API, or with NeoForge. Pick the file for your version and loader on the Files tab.
- Installed on both the client and the server (the server does the mining, the client has the key and the count)
