Very useful thing – a command block that allows you to make a career car. This unit is able to dig up an area the size of 7x7 blocks and place the resources in a chest. Of course, this all only works in a world where creative mode is available, because the creation of the apparatus involved command blocks. Click on the button, a chest appears. In the chest are the elements for marking the dig area. Mark out the area. Turn the lever, and the machine is digging. Turn the lever again, the machine stops.
