[Loot]

I'm not sure what are you actually asking, but on every TP command that you have, make a check if he's frozen, if he does return a message error exactly as you showed above.

pawn Код:

CMD:tp(playerid, params[])
{
     if(Frozen[playerid] == 1) return SendClientMessage(playerid, COLOR_RED, "You cannot use this command when frozen"); // this didn't work so I tried with
     return 1;
}

Why don't you put both filterscript and GM together? Or atleast set frozen players at your GM just as you did at your filterscript.
