Actually sscanf is not necessary when the parameter is a single string. You can use:

pawn Код:

if (!isnull(params)) return UsageMSG(playerid, "/do [action]");

and you just use "params" instead of "action".

Another thing to note is the foreach syntax you are using is deprecated. Use:

pawn Код:

foreach(new i : Player)
