How to use the /fill Coach
- Pick corners A and B. Set the X, Y, Z values or use a preset.
- Choose your block. Search for anything—glass, wool, concrete, wood, stone, brick, etc.
- Select a mode. Replace (solid), Keep (only air), Outline (frame), Hollow (empty inside), or Destroy.
- Preview it. Use 2D top view or the 3D box—tilt and rotate to see it all.
- Copy the command. Bedrock or Java, both ready to paste.
- Optionally print. Print a worksheet or the narrated Story Mode for offline learning.
Pro tip: For big edits, click “Add Undo Plan (Clone backup)”—safety first. 🛟

FAQs
Is this safe for kids?
Yes. It’s practice-only by default and doesn’t run commands in your world. Kids copy the command and paste it in Minecraft when ready.
What’s the difference between Bedrock and Java commands?
Java uses full names like minecraft:glass, while Bedrock can use glass. We show both, ready to copy.
Can I undo my build?
Use the Undo Plan (Clone backup) we generate. It’s a safe way to snapshot and restore.
Does the 3D preview match Minecraft exactly?
It’s an educational preview (lightweight and fast). It represents size, hollow/outline/solid, and block style patterns for learning.
Why won’t “destroy” mode select?
Practice-only mode keeps “destroy” disabled to protect worlds. Turn off Practice-only if you understand the risks.
