Command books
Mostly intended for creative or development purposes. This is similar in spirit to using a chain of command blocks, but more portable and easier setup.
Usage
Write commands into a book-and-quill, one command per lines. To execute the commands, hold the book in your off-hand, and use a stick in your main hand. All commands are run in succession, even if one fails along the way.
The book's user is considered the source of the commands. Usage of books can be locked behind a specific permission level; by default 2 (Game Master).
in v2 (MCÂ 1.21.5), command books are separate from regular book and quils, and are found in the creative inventory under the operator tab. Those require a Debug Stick instead of a regular stick.
Environment
Core functionalities are fully server-side
Client-side installation is recommended to avoid opening the book every time you execute it. It is useless to players without permissions to execute books.
