The Command Block is a block added by Minecraft. It can be used to execute commands.

Guide[edit]

Before MC 1.9[edit]

Player can place down a Command Block and right-click it in creative mode.

MC 1.9 and higher[edit]

The Command Block now has several additional modes:

  • Impulse - same as before.
  • Chain - it will only activate itself, when a command block on opposite side of its arrow is activated
  • Repeating - it will run 20 times per seconds
