@u (Entity Detector)

It is an entity detector that is directed to the entity that has

activated the command.

 

Example:

 

A player presses a button that activates a command block with this selector,

so the player who has pressed the button will be affected by the command block.

    That is already in the game. It is @p (nearest player) or @s (self)

    This is literally @e(emtity selector) and you can select entities with @s or @r too

    It's not possible to tell "who" activated a command block. The command block runs its command when it receives redstone power, which can come from anywhere!

    tryashtar, yeah i know that it's almost impossible v':, but i believe in that 1% that it can be added, and it will simplificate the mapmaking.

    It seems easy to determine "who" activated redstone just by looking at it, but for the game to do that, it would need to keep track of a player UUID for every piece of redstone dust, and potentially every single redstone component, entity, and block that could be modified as part of a chain reaction. Storing all that is currently not possible, and would cause tremendous overhead all for a tiny result.

     

    Since it's not going to happen, you could always use a sign! Signs can run commands when clicked on, and the @s selector will target the player who clicked the sign!
