Addon: Builder's Wand for Fast Construction
Builder's Wand is a survival-friendly tool for placing or removing matching blocks in rows, columns, grids and connected planes. It uses a block selected from the inventory or copies the block you point at, and displays cyan placement outlines or red removal outlines before the action.

Hold the wand and sneak use to open its settings. Choose a building material, placement or removal, the working mode and the row length. A quick sneak attack on a block selects that material without breaking it. Each player keeps independent settings and undo history, making the tool suitable for multiplayer worlds.

Row and Column create straight lines. Grid modes process 3x3 or 5x5 areas, while Plane Projection follows a connected surface of matching blocks and adds a layer of up to 64 blocks. The wand stops at occupied spaces and does not overwrite solid blocks, liquids or plants.

In Survival, every placed block consumes one matching item. Removal returns eligible blocks, and the five-step undo system records both building and demolition actions. Undo only changes blocks that are still untouched and handles returned resources safely. Containers, doors, beds, signs and other unsafe or multi-block structures are excluded.

Craft the wand by placing a Diamond, Blaze Rod and Obsidian vertically in the center column of a crafting table. No experiments, commands or external dependencies are required. Version 1.3.0 contains both necessary packs and requires Minecraft Bedrock 26.30 or newer.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
