title: Move along a path of points with even speed
body: <p>I have a sequence of points and i have an object that should move along the path described by these points.</p>
  
  <p>I know that i need to find the corresponding segment depending on the time, but i dont know how to do this precisely.</p>
  
  <p>Note that the speed should be constant along the path, so you have to take the distance of a segment into account.</p>
