Here is the function for getting the adrenaline bar %:

function GetAdrenalinePercent(): Integer;
var
  BarX1,BarX2,BarY1,BarY2 : Integer;
  tpa : TPointArray;
  box : TBox;
begin
  Result := -1;
  if isActionBarOpen then
  begin
    Result := 100;
    BarY1 := 334 - SRL_NAVBAR_INGAME_Y;
    BarY2 := 337- SRL_NAVBAR_INGAME_Y;
    BarX1 := 49 - SRL_NAVBAR_INGAME_X;
    BarX2 := 469 - SRL_NAVBAR_INGAME_X;
    if FindColorsTolerance(tpa,1776411,BarX1,BarY1,BarX2,BarY2,15) then
    begin
      box := GetTPABounds(tpa);
      Result := Floor(100 - ((BarX2 - box.X1)*1.0 / (BarX2-BarX1) * 1.0) * 100);
    end;
   end;
end;
         

i want to modify this function to read the green health bar of my target enemy. The one in the combat tab. I think this above function can be changed so that it reads that green HP bar rather than the adrenaline bar. Can anyone help me adapt this properly?

Change the BoxY1 and BoxY2 coords. Colors should be the same? Not sure about EOC combat.
