SRL Archive - RS3 Help

Hello, I've been working on a minotaur bot for combat training of noob accounts in rs3 and so far it is going good but one problem is I have no idea how to make the script do ultimate abilities and thresholds. If its possible I would like my script to send key>5 when adrenaline is more then %50 and send key>6 when adrenaline is %100.

procedure doAbilities();
begin
  if (actionBar.getAdrenalinePercent() = 100) then
   begin
     writeLn('Adrenaline is maxed, time for an ultimate');
     sendKeys('6');
     exit;
   end;

  if (actionBar.getAdrenalinePercent() > 50) then
   begin
     writeLn('Adrenaline is not maxed but is over 50, time for a threshold');
     sendKeys('5');
     exit;
   end;
end; 

Something like that?
