BuildPilot

BuildPilot is a client-side-only building mod for Minecraft 26.2 (Fabric). It works on servers that do not have the mod installed — including vanilla servers — and in singleplayer.

How it works

• Press B to toggle Build Mode on.
• Press V to open the radial wheel and pick a shape: Single, Line, Wall or Box — Wall and Box also have fill modes (Filled / Frame / Hollow).
• Right-click a block to set the first corner, aim at the far corner — a translucent ghost preview with a live block count follows your aim — and right-click again to place. Left-click cancels.
• Blocks are placed one at a time through ordinary vanilla interactions, BFS-ordered from the first corner so every block is placed against a real neighbour. The server only ever sees normal placements, exactly as if you clicked each block by hand.
• The XP bar doubles as a build progress bar while a build runs.

Honest limits (client-only)

• No extended reach — everything is within your real vanilla reach.
• No floating placement — every block needs a real neighbour to place against.
• No instant placement — the ghost shows the final shape; blocks fill in one by one as you stay in reach.
• No Fabric API or other dependencies. No server component, no commands, no config screen. Config (max blocks, place rate) lives in config/buildpilot.json.

Install

1. Install Fabric Loader 0.19.3+ for Minecraft 26.2 (Java 25).
2. Drop buildpilot-26.2.jar into your mods folder.
3. Done — both keybinds are rebindable in Options → Controls → BuildPilot.

BuildPilot is an original implementation. Its two-point, radial-menu workflow is inspired by the building style popularised by Effortless Building, but it contains no Effortless Building code, assets or text.
