Minecart with Command Block

A minecart with command block is an impulse‌^{[JE only]} or repeating‌^{[BE & edu only]} command block inside a minecart.

Obtaining[]

The minecart with command block is obtainable only using the command /give @s command_block_minecart, as it does not appear in the creative inventory‌^{[Bedrock Edition only]} and has no crafting recipe. It can also be summoned using the command /summon command_block_minecart. It can be broken like any other minecart, but only the minecart is retained, while the command block is lost.

Usage[]

The minecart with command block combines the functionalities of both minecarts and command blocks. Although the minecart visually contains an impulse command block, it functions more similarly to a repeating command block, and runs its command once every four game ticks when on an active activator rail. When it passes over a detector rail with a comparator connected next to it, it outputs the command block's result.

Sounds[]

Java Edition:
Minecarts with command blocks use the Friendly Creatures sound category for entity-dependent sound events.^{[sound 1]}

- Command: The command entered into the minecart.
- LastOutput: The last line of output generated by the minecart. Still stored even if the gamerule commandBlockOutput is false. Appears in the GUI of the minecart when right-clicked, and includes a timestamp of when the output was produced.
- SuccessCount: Represents the strength of the analog signal output by redstone comparators attached to this minecart. Only updated when the minecart is activated with an activator rail.
- TrackOutput: 1 or 0 (true/false) - Determines whether the LastOutput is stored. Can be toggled in the GUI by clicking a button near the "Previous Output" textbox. Caption on the button indicates current state: "O" if true,"X" if false.
