title: Android - Moving an object in circle
body: <p>I'm having trouble with something,
  I need to make an object (Pong paddle) to move only in a circular route along the screen.
  same thing as if you would have a constant y axis value and it would only move along the x axis as u drag ur finger on it, but to restrict it to a circular route.</p>
  
  <p>any insights?
  I saw this thing

  <p>and it only helps in figuring out how to move something constantly at a circle (eventhough it's Flash, the idea is the same)</p>
  
  <p>Thanks</p>
