It worked here. Now run it in your world.

The sandbox is a copy — your real save is where it counts. Take the command you built into a project and watch it land.

Quick calculators

Little math the game makes you do — done for you.

Portal calculator

Overworld ↔ Nether coordinates — the Nether is 1:8 scale.

Build the matching portal within ~16 blocks of the target and the game links them. The Nether roof sits at Y 128.

Tick converter

20 ticks = 1 second. A full day is 24,000 ticks (20 real minutes).

XP calculator

Levels ↔ points, with the exact /xp command for your edition.

Chunk finder

Which chunk — and region file — a block position lives in.

Chunks are 16×16 blocks. Java region files hold 32×32 chunks (r.x.z.mca).
