Making the command override able to use the name of the player using the command

[esuareze]

Many commands refer to a player. Sometimes its nice to restrict a player to only use a command on himself or a variation of his name.

In my case im using carpet mod and it enables us to spawn bots. I would like to give permission to some of my players to only spawn 1 bot. And that bot would have to have the name of the player +"_bot".

So if %n enabled me to refer to the player's name, I would allow "/player %n_bot spawn".
