Overview
Effortless WorldBuilding brings fast, powerful building tools to Minecraft 1.21.11 (Fabric). Works on both single-player and multiplayer servers! Build shapes, mirror builds, create arrays, and see real-time dimension counts while you place.
Features
- Build walls, lines, circles, spheres, cylinders, cubes, slopes, pyramids, domes, and cones
- Dimension Display: See block counts while placing (e.g., "5 x 3 x 5 | 75 blocks" for a 5-block line)
- Up to three live mirroring planes (X/Y/Z) and both linear and radial arrays
- Quick Replace toggle to overwrite any block with your selected block
- Real-time particle previews and infinite reach placements
- Undo up to your last 50 building actions
- Dual control: chat commands or the WorldBuilder item menu
- Survival-friendly: consumes blocks from inventory; Admin-only to prevent griefing
How to Use
- Obtain the WorldBuilder item and right-click to open the menu.
- Choose a shape (e.g., Line, Sphere, Cube) and set your two positions.
- Watch the screen: You'll see dimensions like "5 blocks" for a line or "10 x 5 x 10 | 500 blocks" for a cube.
- Set mirror planes (X/Y/Z) and enable arrays if needed.
- Toggle Quick Replace when you need to overwrite existing blocks.
- Aim where you want to build and confirm to place blocks.
- Made a mistake? Use the menu or
/build undoto revert.
Commands
/build mode <shape>- Set shape type (cube, sphere, line, wall, etc.)/build radius <number>- Set radius for circular shapes/build mirror <x/y/z> on/off- Toggle mirror planes/build quickreplace on/off- Toggle quick replace mode
Tips & Tricks
- The dimension display shows exact block counts - perfect for counting materials before building
- For lines, you'll see just the block count (e.g., "15 blocks")
- Use hollow shapes to save materials on large builds
Known Limitations
- Access is restricted to server operators; regular players cannot use these tools
- Undo history is capped at 50 actions
- Very large builds may cause brief lag on lower-end hardware
- Dimension display requires the mod on both client and server for multiplayer
