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.

1. Right click a face with any block in hand — the first block is placed by vanilla.
2. Keep holding and move your crosshair away — ghost blocks appear along the drag.
3. 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.

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.

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.
