RadialTPAWalk - guess by who...

MinPix - how many pixels a square of the color must contain

SR, ER - StartRadial, EndRadial

MinD, MaxD - min distance, max distance

Color - the color to walk "at".

This function is compass angle independent, you don't need to do anything to the angles yourself or worry about the angle shifting...

SCAR Code:

Function RadialTPAWalk(Color: Integer; MinPix, SR, ER, MinD, MaxD: Integer): Boolean;
Var
  TPAA: Array of TPointArray;
  X, Y, Z, I, S, E: Integer;
  TPA: TPointArray;
Begin
  FindColorsSpiralTolerance(MMCX, MMCY, TPA, Color, MMX1, MMY1, MMX2, MMY2, 0);
  FilterPointsPie(TPA, 0, 359, MinD, MaxD, MMCX, MMCY);
  TPAA := TPAToATPA(TPA, Round(Sqrt(MinPix)));
  S := SR + Round(Rs_GetCompassAngleDegrees);
  E := ER + Round(Rs_GetCompassAngleDegrees);
  If S > 360 Then S := S - 315;
  If E > 360 Then E := E - 315;
  Writeln(IntToStr(S));
  Writeln(IntToStr(E));
  For I := 0 To High(TPAA) Do
  Begin
    MiddleTPAEx(TPAA[i], X, Y);
    Z := Round(Degrees(ArcTan2(MMCY - Y, MMCX - X))) - 90;
    If Z < 0 Then
      Z := Z + 360;
    If Z > SR Then
      If Z < ER Then
      Begin
        MouseFindFlag(X, Y, 1, 1);
        Flag;
        Result := True;
        Exit;
      End;
  End;
End;

Why do you filter the degrees yourself? Don't trust FilterPointsPie with it? :p

SCAR Code:

FindColorsSpiralTolerance(MMCX, MMCY, TPA, Color, MMX1, MMY1, MMX2, MMY2, 0);

finds the points center-out.. the opposite of RadialWalk.

Also, RadialWalk scans a distance from start to endradial.. This doesn't scan any particular direction?

I suggest using RadialWalkEx:

SCAR Code:

function RadialTPAWalk(Color: Integer; MinPix, SD, ED, MaxR: Integer): Boolean;
var
  i, d, x, y: Integer;
  tpa: TPointArray;
  atpa: TPointArrayArray;
begin
  Result := False;
  d := Round(Rs_GetCompassAngleDegrees);
  if (d < 0) then Exit;
  if (not RadialWalkEx(tpa, MMCX, MMCY, Color, 0, SD + d, ED + d, MaxR)) then Exit;
  atpa := TPAtoATPA(tpa, Round(sqrt(MinPix)));
  for i := 0 to High(atpa) do
    if (Length(atpa[i]) > MinPix) then
    begin
      MiddleTPAEx(atpa[i], x, y);
      if MFNF(x, y, 1, 1) then
      begin
        Result := True;
        FFlag(10);
        Break;
      end;
    end;
end;

For crying out loud, just copyright the word "TPA"!

Everytime I see a topic in "SRL New Functions" or "Public Test Corner" with the word "TPA" in it, I go in and see it's you!! Jesus!!

I've tried it and didn't work ;)

Also, the Spiral is for habit, and it makes no difference - this function does work just as designed.

Hahaha very true :)

He will not stop before he gets to DEV...
Looks nice to me since I can't understand it^^

What filterpoints Pie does?

And where could I get list of all TPA/misc functions of scar...like exit, abs, TPAtoGasp etc...

I mean those what arent displayed in scar help file?

Gap, not Gasp! :p

Gap is like a... hole :)

They are in WizzyPlugin, (talking of the TPA stuff) -

.includes\SRL\SRL\Misc\WizzyPlugin.scar

or www.srl-forums.com/srl-repos/ -> Place inside plugins folder -> WizzyPlugin.drp since WizzyPlugin.scar doesn't show them all.

Filter points pie "takes a slice of a pie"+(describes the circle)+"with set angles and radius"

And not after ;)


EDIT: By the way, if you do want long steps, make it For I := High(TPAA) DownTo 0 Do :)
