getnearestplayer(x,y)
 

You don't really specify a distance... so what does Graal consider a near player, and not a near player? Only within a 'level'(distance < 32). Literally visible to the player? The player is loaded in the loaded levels on a gmap? If the last is true, then what makes it difference than just using level.players?

Fairly certain it's within 64 tiles of a player (32 would not work since players on opposite sides of levels are found).
