title: How do I set the boundaries of a 2d ortographic camera in unity to modify according to the screen size
body: <p>Here is the script that I am using for the camera. Right now, I manually have to set the boundaries by positioning the camera where it looks like it's the limit of the border. There are a few problems though. If i change the aspect ratio of the viewport in Unity, the boundaries won't work as intended.</p>
  
  <p>What I'm looking for is a way to 
  - see the maximum boundaries set(like an empty game objectt idk)
  - see where the camera can move(in the inspector with Gizmos.DrawLine)</p>
  
  <p>Basically i want a system that i can reuse for other scenes with different boundaries size and that adapts to the screen's size. Thanks in advance</p>
