title: Scene2d: Circular hitbox for an actor
body: <p>Is there a way to make an Actors hitbox beeing circular. Or if for example add an Inputlistener and check if the touch point is inside the circle or else pass the input to the next actor that would be hit.</p>
  
  <p>Its important for me if the hit is not in the circle but in the bounds of the actor, the event passes to the next actor that would be hit.</p>
