pawn Код:

format(string,sizeof(string), "Stranger", randomID);
SetPlayerName(playerid, string);

You formatted the string but forgot to add the placeholder, try this:

pawn Код:

format(string,sizeof(string), "Stranger%d", randomID);
SetPlayerName(playerid, string);

You should hide the player's name for other players rather than setting the player's name, good job though.
