BuildRush

Hold right click and drag to build a whole line — or a whole wall — in one go.

A small, focused Fabric mod for Minecraft 26.2. Place one block the normal way, keep the button held, and drag your crosshair: a preview of ghost blocks follows your aim. Let go, and they all get placed at once.

How it works

Right click a face with any block in hand — the first block is placed by vanilla.
Keep holding and move your crosshair away — ghost blocks appear along the drag.
Release — every green ghost is placed.

Drag along one axis to build a line. Keep drifting sideways and it becomes a rectangle — the second axis is picked up automatically.
Green ghosts mean you have enough blocks. Red ghosts mean you have run out — they simply will not be placed.
Vanilla's auto-repeat placement is suppressed while dragging, so holding the button never spams single blocks.
Clicking a door, chest or any other interactive block behaves exactly as usual — no drag starts, because no block was placed.

Counting your blocks

BuildRush counts what you actually have, including blocks stored inside any item with the vanilla container component — shulker boxes, backpacks from other mods, and so on. No hard dependency on any storage mod: if it uses the vanilla component, it works.

Server friendly

The client only ever asks. Everything is validated server side before a single block is placed:

at most 128 blocks per drag,
target must be within 40 blocks of the player,
every position must be genuinely replaceable and unobstructed,
blocks are consumed from the inventory (and containers) by the server itself,
spectators are ignored.

This means BuildRush is safe to run on a multiplayer server: a modified client cannot place blocks it does not own, reach further than allowed, or exceed the limit.

Works in single player too — the integrated server runs the same validation.
