title: Heading from Point A to Point B in 2D space?
body: <p>I'm working on a project which requires me to calculate the heading from a variable point A to a variable point B in 0 - 360 degrees to let the object at point A face point B.</p>
  
  <p>Now, I'm unsure on how to achieve this, I googled but didn't find any good solution.</p>
  
  <p>How would I calculate the heading from point A to point B in 2D space in any situation?</p>
