Groundworks

Groundworks allows to place multiple copies of a block in one drag, see a preview before confirming the placement, turn, raise and lower the block, and take a line back up in one go. Perfectly working with vanilla blocks.

Why?

Because I've been spoiled by the way other automation games and many Minecraft mods allow easy block placement and dismantle.

NeoForge, Minecraft 26.1.2 only. Groundworks is early work, so please report any issues you find on GitHub.

To play Groundworks beside every other FactoryWorks mod, install the FactoryWorks Showcase modpack from CurseForge.

Features

• See it before you place it. Hold a block whose placement depends on how you place it, such as stairs, slabs, logs, doors or rails, and a translucent preview shows exactly what a click would put down, in blue where it replaces something and in red where it would be refused.
• Rotate before you place. Press R to turn the next placement a quarter from the way you look, and Shift+R to turn it back. With nothing in hand that places, aim at a block already standing and press R to turn it in place.
• Raise and Lower. Press G or B to move the next placement one block up or down, so you can place in mid-air or at a height you can't aim at.
• Stretch a whole line. Sneak-click with stairs, slabs, fences, walls, panes, logs or rails to start a stretch, sneak-click again to add a corner, then click where it ends. The line is laid, and paid for, in one go, goes round a block in its way, and joins up as vanilla joins it: stairs climb as a staircase, rails slope, fences connect.
• Columns straight up or down. Ladders and chains stretch as a column: sneak-click to start, press G or B to set its height, click to lay it. A tall ladder is one gesture, however far above you it climbs.
• Dismantle a line. Sneak-click a fence, wall, iron bar or rail with the tool that breaks it, then click another of the same kind: everything joined between them comes up into your inventory.

For pack developers

Which blocks and items each feature reaches is data. Each feature has one tag, shipped with defaults, which a datapack changes with no code: groundworks:plan_opt_in, groundworks:rotates_in_place, groundworks:stretches, groundworks:stretches_vertically, and the families under groundworks:dismantle_family/. The server config's planOptInNamespaces gives every block of a mod a preview in one line.

For mod developers

Groundworks is also a library. A mod plans its own items' placements, stretches and dismantles through it, and draws its own additions through its hooks, so everything on one screen places, previews and dismantles one way. Beltworks is built this way, and bundles Groundworks inside its jar.

Dependencies

None beyond NeoForge. Groundworks is needed on both the client and the server.
