How to Target
General targets:
name - Exact name match, or partial name match (if the partial string is unique).
#userid - If userid is numeric, the player will be targeted by their userid (found via the "users" command).
#steamid - Matches by Steam ID. If you use colons (:), you must enclose in quotes. Otherwise, you can use an underscore (_) instead. Examples: "#STEAM_0:1:4433", #STEAM_0_1_4433
#<name> - Exact name match after the # sign.
@all - All players (available on most commands).
@Bots - All bots (available on most commands).
@alive - All alive players (available on most commands that accept alive players).
@dead - All dead players (available on most commands that accept dead players).
@humans - All non-bot players (available on most commands).
@aim - Current player the admin is directly aiming at.
@me - Target self.
@!me - Target everyone but yourself.
Note that name matches occur last, "magic targets" (such as # and @) are processed first. This means that "@all" will target @all players, even if there is a player named "@all". You should target "#@all" instead.
