OK, becasue I have not found this function from SRL, I decided to create the function.
Like we all know that rs is updating everyday multiple times.
Returns true, if "RuneScape Has Been Updated" note is visible on screen.
Simba Code:
function RsUpdated : boolean;
var
x,y,UpdateText : Integer;
begin
UpdateText := BitmapFromString(34, 12, 'beNq9U1sKgDAM640EHfrh1' +
'T2M/17CQiCETtzGpiMfJXRJH1uatjQM+zYDAzUd13n842Jm9WV85' +
'6IJasrYA0LHoryLYEqaGRgVpCljBDi8joAkMiFLkquhQtGlhgyNP' +
'yb0u6D+0GCTy7p0NRieR95yWF9xODlJHqUCJidsHwyTA/9CannF1' +
'+76RPPPugFRCGcb');
result := FindBitmap(x,y,UpdateText);
FreeBitmap(UpdateText);
end;
