SRL Archive - OSR Help

Basically, I've got everything else working but I can't for the life of me figure out how to make RadialWalk search in the correct area, like so:It should search in that area with -20 and 20, or 340 and 380, or 700 and 740, or anything like that, right?
Instead, seemingly no matter which variation of '-20, 20' I put into the function, it searches in this kind of area:
I can tell because it walks south when it's supposed to be walking north. Also, these images are not the exact location I'm having this problem in.

Please help, I'm stumped.

The specific function I'm using is RadialWalkTolerance, if that makes a difference

Use 340,20. And here is the proof

program new;

function getBlackSquare:TPointArray;
var
  x,y:Integer;
begin
  setLength(result,100*100);
  for x := 0 to 99 do
    for y := 0 to 99 do
      result[x*100+y] := Point(x,y);
end;

var
  points:TPointArray;
  bitmap:integer;

begin
  DisplayDebugImgWindow(100,100);

  points := getBlackSquare;

  FilterPointsPie(points,340,20,0,100,50,50);  //as you can see,340 and 20 works like a charm

  bitmap := CreateBitmap(100,100);

  DrawTPABitmap(bitmap,points,2927209);

  DrawBitmapDebugImg(bitmap);
end.          

It's still doing it, even though the FilterPointsPie snippet seems to do it fine.

The 3rd screenshot is from the moment when it clicks on the road to the south instead of the road to the north. I can make this mostly work by making it walk a bit more to the east and then searching between 340 and 359, though, but that's suboptimal and a bit unreliable.

I checked in mapwalk.simba and I think this might be the cause:

  
if (SD > ED) then
    Swap(SD, ED);

That's in RadialWalkEx, the function that the other radialwalks seem to be built from, and SD is variantToDirection(StartRadial) and ED variantToDirection(EndRadial)

Testing results:
versus

RadialWalkEx for reference:

function RadialWalkEx(var TPA: TPointArray; cx, cy, TheColor, tol: Integer; StartRadial, EndRadial: Variant; Radius: Integer): Boolean;
var
  time: Integer;
  SD, ED: extended;
begin
  Result := False;
  if (not LoggedIn) then Exit;

  SD := variantToDirection(StartRadial);
  ED := variantToDirection(EndRadial);
  if (SD = ED) then
  begin
    srl_Warn('RadialWalkEx', 'StartRadial = EndRadial, using LinearWalkEx.', warn_Warning);
    Result := LinearWalkEx(tpa, cx, cy, TheColor, tol, StartRadial, Radius);
  end;
  if (SD > ED) then
    Swap(SD, ED);

  time := GetSystemTime;
  try
    FindColorsTolerance(tpa, TheColor, MMX1, MMY1, MMX2, MMY2, tol);
    FilterPointsPie(tpa, SD, ED, 10, Radius, cx, cy);
    SortCircleWise(tpa, cx, cy, StartRadial, False, StartRadial > EndRadial);
    Result := (Length(tpa) > 0);
  except
    srl_Warn('RadialWalkEx', 'An exception has occured', warn_AllVersions); Exit;
  end;
  srl_Warn('RadialWalkEx', 'Took ' + IntToStr(GetSystemTime - time) +
    ' ms, found' + IntToStr(Length(TPA)) + ' points', warn_Debug);
end;

I will find this out.

Thanks in advance :D
