I am trying to write a function that make my arrow point to true north regardless of which way its point at a certain point of time. So far I have (Code below). Everytime I run it it tells me I have to many input arugements. Im not sure if im writing this correctly.
function turnNorth()
(getHeading(2))
turnLeft();
(getHeading(3))
turnLeft();
turnLeft();
(getHeading(4))
turnLeft();
turnLeft();
turnLeft();
end

My guess is that you need
function turnNorth()
current_heading = getHeading;
switch current_heading
case 2:
turnLeft();
case 3:
turnLeft();
turnLeft();
case 4:
turnLeft();
turnLeft();
turnLeft();
end
