Minecart with Command Block

A minecart with command block is a command block inside a minecart.

Obtaining
Minecart with command block is only obtainable using commands. It can be broken like any other minecart, but 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 will output the command block's result.

Entity data
