Getting .Bounds from a list item

Hello, I have some code that constrains my camera to a bound box, but I'm having some trouble getting the bounds for the box from my list. Here is the code to constrain my camera

Code (csharp):

1.  
2.  public static void ConstrainCamera(Camera camera, Bounds bounds) // float roomZoom, bool HardBoundaryUp, HardBoundaryLeft, etc.
3.     {
4.         float left = camera.ViewportToWorldPoint(new Vector3(0f, 0f, 0f)).x;
5.         float right = camera.ViewportToWorldPoint(new Vector3(1.0f, 0f, 0f)).x;
6.         float top = camera.ViewportToWorldPoint(new Vector3(0f, 1.0f, 0f)).y;
7.         float bottom = camera.ViewportToWorldPoint(new Vector3(0f, 0f, 0f)).y;
8.  
9.  
10.         if (top > bounds.max.y)
11.         {
12.             float topDiff = bounds.max.y - top;
13.             camera.transform.position += new Vector3(0, topDiff, 0);
14.  
15.         }
16.         else if (bottom < bounds.min.y)
17.         {
18.             float botDiff = bounds.min.y - bottom;
19.             camera.transform.position += new Vector3(0, botDiff, 0);
20.  
21.         }
22.  
23.         if (right > bounds.max.x)
24.         {
25.             float rightDiff = bounds.max.x - right;
26.             camera.transform.position += new Vector3(rightDiff, 0, 0);
27.  
28.         }
29.         else if (left < bounds.min.x)
30.         {
31.             float leftDiff = bounds.min.x - left;
32.             camera.transform.position += new Vector3(leftDiff, 0, 0);
33.         }
34.  
35.     }
36.  

and this is what I'm currently trying to use to input the required variables into the method.

Code (csharp):

1.  
2.  private void FixedUpdate()
3.     {
4.         currentBoundary = Room.rooms[Room.rooms.Count - 1].GetComponent<BoxCollider2D>().bounds; //I have a public static Bounds in Room for this, but I cannot access it.
5.         ConstrainCamera(GetComponent<Camera>(), currentBoundary);
6.     }
7.  

I think it's not working because I'm trying to get a specific instance of Room for its bounds. I have greatly appreciated all the help I have received thus far while working on optimizing my camera, although seeing as I seem to get hung up at almost every juncture, I will most probably continue to implore assistance.

 

what error do you get when you try to get the bounds?

 

So initially, instead of

Code (csharp):

1. currentBoundary = Room.rooms[Room.rooms.Count - 1].GetComponent<BoxCollider2D>().bounds;

I had

Code (csharp):

1.  currentBoundary = Room.rooms[Room.rooms.Count - 1].boundaryBox

The .boundaryBox is a static variable of the boundaries set inside each instance of Room (which is attached to a gameObject with a BoxCollider2D), and I get a "error CS0176: Static member `Room.boundaryBox' cannot be accessed with an instance reference, qualify it with a type name instead" when I try to use it. The way I showed initially just gets the bounds of whatever room was instantiated most recently, and then refuses to move from that room in game.

 

Static variables are accessed via the Type name. So "Room.boundaryBox" is the way to get that value. Static variables are shared by all instances of that type. If each instance of Room should have a different boundaryBox, then it shouldn't be static.

 

Oh! that explains a lot actually. I'm now going to go revise 50% of all the static vars I have used (incorrectly) thus far. Learn something new everyday. Yep that was my problem. Thank you! c:

 

also your "please use code tags" link was pretty helpful.
