title: Calculate the direction of an object with geographical coordinates (latitude, longitude)
body: <p>I have the coordinates of a player and another object. Both are with geographical coordinates (Latitude and longitude). I have also the direction in what the player is facing (compass). How can I calculate the angle to the other object from the player direction? e.g. I want to know if the object is to the right/left of the player and how many degrees.</p>
  
  <p>Thanks a lot!</p>
