native Text3D:CreateDynamic3DTextLabel(const text[], color, Float:x, Float:y, Float:z, Float:drawdistance, attachedplayer = INVALID_PLAYER_ID, attachedvehicle = INVALID_VEHICLE_ID, testlos = 0, worldid = -1, interiorid = -1, playerid = -1, Float:streamdistance = 100.0);

Simply change it to the playerid you want to attach the label to.

PS: I don't really see the point of using dynamic 3D texts for players cause default 3D text limit is 1024 which is enough for your playerbase. I use dynamic 3D text labels for other stuff only, like house door text, vehicles etc.
