Executors

Executors perform an action on the target block. Each takes one argument, which can be a literal or a value_of() expression.

Some executors are only available for specific block types. If the target block is not compatible, the executor is silently skipped.

All Blocks

Available on: any target block

Executor	Argument	Description
`set_redstone`	`<0-15>`	Provides a redstone signal to the target block.

Examples:

set_redstone 15
set_redstone value_of(get_page - 1)

Data Lectern / Lectern

The following commands require the target block to be a Data Lectern or a regular Lectern with a book.

Executor	Argument	Description
`set_page`	`<1-100>`	Sets the current page of the book in the lectern. Pages are 1-based.
`write_page`	`<string>`	Writes text to the current page, replacing its existing content.

Examples:

set_page 1
set_page value_of(redstone + 1)

write_page "Hello, world!"
write_page value_of(dimension as_string)

Radio Transmitter / Radio Receiver

The following command requires the target block to be a Radio Transmitter or Radio Receiver.

Executor	Argument	Description
`set_frequency`	`<frequency>`	Sets the radio channel the block is tuned to (an integer from 1 to 64).

Example:

set_frequency 10

Robotic Arm

The following commands require the target block to be a Robotic Arm.

Unlike other executors, the argument is a block position (x y z) telling the arm which block to act on, not a value applied to the arm itself. The arm first swings its hand to that position, then performs the action. The target must be within 4 blocks of the arm; positions out of range are skipped.

Executor	Argument	Description
`take_items`	`<x y z>`	Pulls items from the inventory at the target position into the arm’s hand.
`put_items`	`<x y z>`	Deposits the arm’s held items into the inventory at the target position.
`use`	`<x y z>`	Right-clicks the target with the held item (place a block, fill/empty a bucket, use an item, …).
`shift_use`	`<x y z>`	Sneak right-clicks the target with the held item.
`drop_items`	`<x y z>`	Drops held items into the world at the target position as item entities.
`set_transfer_count`	`<int>`	Sets the maximum stack size moved by `take_items`, `put_items`, and `drop_items` (1-64).

take_items, put_items, and drop_items move at most the transfer amount configured in the arm’s GUI (1–64) per instruction; any remainder stays in the arm’s hand. use and shift_use interact with the held item and do not transfer a quantity.

Examples:

take_items 1 3 5
put_items 0 1 2
set_transfer_count 16
drop_items 0 2 2

use 0 1 2
use value_of(pos offset_y 1)
