All commands will be executed on behalf of the player who placed the command block, as if the player typed in the commands. This player is said to be the “commander” of the block.
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
Command blocks support placeholders, insert one of these placerholders and they will be replaced by a player name:
• “@commander”: commander of this command block
• “@nearest”: nearest player from the command block
• “@farthest” farthest player from the command block
• “@random”: random player currently in the world
Example 1:
time 12000
