pawn Код:

public OnPlayerText(playerid, text[])
{
    new Rank[20];
    switch(GetPlayerScore(playerid))
    {
        case 0 .. 10: format(Rank, sizeof(Rank),"[Newbie]");
        case 11 .. 20: format(Rank, sizeof(Rank),"[Beginner]");
        //etc..
    }
    new ChatText[128], Nameasd[MAX_PLAYER_NAME];
    GetPlayerName(playerid, Nameasd, MAX_PLAYER_NAME);
    format(ChatText, sizeof(ChatText),"%s %s: %s", Rank, Nameasd, text);
    SendClientMessageToAll(-1, ChatText);
    return 0; // ignore the default text and send the custom one
}
