[Loot]

I wouldn't use the native params for that, but:

pawn Код:

YCMD:spec(playerid, params[], help)
{
    new iPlayer;
    if(sscanf(params, "u", iPlayer)) return SendClientMessage(playerid, COLOR_WHITE, "TYPE: /spec [id/name]");
    if(iPlayer == INVALID_PLAYER_ID) return SendClientMessage(playerid, COLOR_GREY, "The player isn't connected!");
    //etc.
}
