Question by kekrot · Feb 23, 2014 at 02:34 PM · camera2d platformercamera-scrolling

How to stop the camera from going out of bounds in a 2D platformer?

I have a camera that follows the player, as a child object of the player. But when I move the player across the scene, I need the camera to stop so that it doesn't show what's outside the scene. Here's what I wrote so far in a Camera Script attached to the camera.

1.57 is the width of the full background.

     void FixedUpdate ()
     {
         if (transform.position.x <= (1.57 / 2)
             transform.position = new Vector2 (1.57 / 2);
     }

If the camera tries to move outside the background I want it to be held back. But the script doesn't work at all...

Also the width and height of the levels varies a lot, so I would like to know how to just make the camera know that it isn't allowed to go farther than what the background shows. Like a huge invisible object in the background which covers the entire stage. If the camera tried to show what is outside of that box object, it would automatically be put back.
