Minecraft Command Block Generator
A project hub for large command block systems — click to place impulse, chain, and repeating blocks, validate each command, simulate ticks in a console, then export /give NBT or a full grid backup file.
What you can do here
- Visual grid — click empty cells to add blocks; click a block to edit its command
- Chains — set facing so chain blocks run after the block pointing into them
- Tick console — watch repeating blocks fire on a period (100 ticks ≈ 5 seconds)
- Export / import — JSON grid file for backups; also
/givelists,.mcfunctionnotes, print guide
Writing one complex summon or give string? Use the Minecraft Command Generator, then paste it into a block on this grid.

Impulse, chain, and repeating command blocks
Minecraft has three command block types. This hub color-codes them like the game so you can plan a chain before placing anything in Creative.
Impulse
Orange. Runs once when powered (or once if Always Active). Use Pulse redstone in the inspector to test in the tick console.
Chain
Green. Runs when the command block pointing into it succeeds. Align facing arrows on the grid the same way you face blocks in-world.
Repeating
Purple. Set a period in ticks (20 ≈ 1s, 100 ≈ 5s). Press play on the console to see each fire while you tune timing.
How to build a command block chain (quick)
- Enable cheats and run
/give @s command_block(or use Copy /gives from this tool for pre-filled NBT). - On the grid: place an impulse or repeating block as the start, then chain blocks in the direction of its facing arrow.
- Paste or type each command (no leading
/needed in the block UI). Fix any validation errors shown in the inspector. - Press play on the tick console to confirm order and timing, then Export grid or Copy /gives for Creative.
- In-world, place blocks in the same order and facing. Set Conditional / Always Active to match the inspector.
