You can optionally use the following placeholders in your commands:
|
|
• “@nearest” is replaced by the name of the player nearest to the command block
|
|
• “@farthest” is replaced by the name of the player farthest away from the command block
|
|
• “@random” is replaced by the name of a random player currently connected
|

To execute the commands, supply the command block with redstone power once. To execute them again, you have to turn the power off and on again.]],
