Hello guys...
Yesterday i made cmd that freezes player, heres code:

pawn Код:

CMD:freeze(playerid, params[])
{
    new id;
    new msg[50], string[128], string1[128], string2[128];
    if(sscanf(params,"us[50]",id,msg)) return SendClientMessage(playerid, -1, "Usage: /freeze [id] [reason]");
    TogglePlayerControllable(id,0);
    SetPVarInt(id,"freeze",1);
    format(string, sizeof(string), "You have frozen %s for reason: %s", PlayerName(id),msg);
    SendClientMessage(playerid, COLOR_GREEN, string);
    format(string1, sizeof(string1), "You have been frozen by Admin, reason: %s", msg);
    SendClientMessage(id, COLOR_RED, string1);
    format(string2, sizeof(string2), "%s has been frozen by Admin (%s)", PlayerName(id), msg);
    SendClientMessageToAll(COLOR_RED, string2);
    if(id == playerid) return SendClientMessage(playerid, COLOR_YELLOW, "Error: You cannot use this command on yourself");
    if(id == INVALID_PLAYER_ID) return SendClientMessage(playerid, COLOR_YELLOW, "Error: This player is not connected");
    return 1;
}

now...i want to make this cmd to check is player already frozen so if i type /freeze id reason but player is already frozen it will say to me: Error: this player is already frozen.
