Vocк pode fazer assim:

pawn Code:

public OnPlayerConnect(playerid)
{
    neve(playerid);
    return 1;
}

forward neve(playerid);
public neve(playerid)
{
    if(snowOn{playerid})
    {
        DeleteSnow(playerid);
        SendClientMessage(playerid, 0x00FF00AA, "* It's not snowing anymore now.");
    }
    else
    {
        CreateSnow(playerid);
        SendClientMessage(playerid, 0x00FF00AA, "* Let it snow, let it snow, let it snow!");
    }
    return 1;
}

#EDIT
