Builder's Wand is a survival-friendly building tool that places matching blocks in lines, grids, or across connected surfaces. Choose a material from your inventory, click any suitable surface, and build without placing every block by hand.

Features

Selectable building material — choose a supported block from your inventory or copy a block directly from the world.
Four placement modes — Row, Grid 3×3, Grid 5×5, and Plane Projection.
Live preview particles — see the valid placement positions before using the wand.
Survival-friendly resource use — every successfully placed block consumes one matching item; Creative mode does not consume materials.
Safe placement — existing solid blocks, liquids, plants, and other occupied positions are not overwritten.
Undo last placement — restore unchanged blocks and refund their materials from the settings menu.
Per-player settings — mode, row length, material, and preview preference are saved independently.
Multiplayer friendly — each player has their own configuration and undo history.

How to use

Import the .mcaddon and activate both the Behavior Pack and Resource Pack in your world.
Craft the Builder's Wand at a crafting table.
Put the blocks you want to use in your inventory.
Hold the wand and sneak + use to open its settings.
Open Building Material and choose a supported block from your inventory. Select Copy Target Block if you prefer the wand to copy whichever block you use it on.
Choose a placement mode and, for Row mode, set the desired row length.
Stop sneaking and use the wand on a block face. The clicked face controls where the new blocks are placed; the selected material controls which block is placed.

Quick material picker

While holding the wand, sneak + attack a block to select that exact block as the building material without opening the menu. The sampled block is not broken.

Placement modes

Row — places a straight row, up to the configured length, and stops at the first blocked position. On the top or bottom of a block, the row follows your horizontal view direction.
Grid 3×3 — checks a 3×3 area centered on the clicked block and adds a new layer only in front of matching source blocks.
Grid 5×5 — the same behavior across a larger 5×5 area.
Plane Projection — follows a connected surface of identical source blocks and adds one layer in front of it, up to 64 blocks per use. Diagonal-only connections are ignored.

Preview and undo

Toggle Preview Particles in the settings to show or hide planned placement positions.
After building, open the settings and choose Undo Last Placement. Only blocks that are still unchanged are removed; their materials are returned in Survival mode.

Crafting

Place these ingredients vertically in the center column of a crafting table:

Diamond at the top
Blaze Rod in the middle
Obsidian at the bottom

Notes

The wand needs a block face as an anchor; it does not place a floating block at an arbitrary point in empty air.
Doors, beds, containers, signs, and other multi-block or data-carrying blocks cannot be selected because copying them would be unsafe.
If you run out of the selected material, the wand places as many blocks as are available and then stops.
No experiments, commands, or additional add-ons are required.
