if you whant to put the player names in a menu you can use the configstrings command to show the numbers for the menu where you can access the player name.
Effectively i need to get the player name for a menu once it has been picked from the list of configstringitems. Thanks for the command DoubleKill!
But actually, my question was about Elgan' spectator mod that allows to spec the same player as long as you want. It uses a spawned camera that follows the spec'd player while the spec'ing player is turned invisible and notsolid and stuck to the coords he was on when he started specing. So the displayed name in the screeny is the one of the players passing by the invisible specing player but not the spec'd guy's one.
