title: Unity: how to fade away scene for few seconds
body: <p>I'm programming a simple game, in which the player has to collect some objects. What I would like to do is that after he collects an object, the scene fades away for few seconds and then the player position is changed.</p>
  
  <p>I know how to change the position, I have no idea how to make the fade away effect. I've tried using the Image Effect (such as Vortex and Blur) but I'm no able to slowly increment their variables (e.g. angle value for Vortex and blur iteration for blur) so that gives the impression of an animation.</p>
  
  <p>Could someone guide me through this?</p>
