About this Mod

Command Block Editor

Command Block Editor is a utility mod that makes creating and managing command block systems much faster and more convenient.

Instead of editing command blocks one by one, you can write multiple commands in a single editor and automatically generate complete command block chains.

Perfect for map makers, technical builders, and anyone who works with large command block setups.

Opening the Editor

Press the configured keybind (default: =) to open the editor.

  • If you are looking at a command block, the editor will open with that command block's commands loaded.
  • Otherwise, a new command block will be created at your current position and opened in the editor.
  • Press Ctrl + S to save and close the editor.

Editor Syntax

Syntax Description
<number> Repeat a command multiple times.
! Make the first command block a repeating command block.
@ Toggle auto mode. On the first command it enables auto mode, on subsequent commands it disables it.
? Make a command block conditional.
`expression` Evaluate a mathematical expression.

Expressions support:

  • i iteration index
  • + addition
  • - subtraction
  • * multiplication
  • / division
  • ( ) parentheses

Example

Input:

5: say `i+1`
say hi
?: say hi

Output:

say 1
say 2
say 3
say 4
say 5
say hi
say hi (conditional)
