title: How to detect when an actor is touched in libgdx?
body: <p>I am using "Gdx.input.isTouched()" in the render method of my Screen method, to know where is touched, but when the touch is dragged in the screen, it also activates the events i want only when an actor is touched.</p>
  
  <p>Is there any listener to know when an Actor is touched, but the event is not the dragged one, im doing it with sprites.</p>
