Camera that slides to next room

Hello, I am working on a 2D roguelike sidescroller, and I am stuck on camera movement. I need it to slide to the next room when ever the player walks up to a door on the left or right side. I was hoping for something like this:

. I have no progress on this, so any help would be great!

 

If you think changing scenes it would be easier to create like part of the map on isolated part of level.
If you think slide to next area of level like LINK in canyon you can lerp the vector3 of camera position. Ofcourse you need to calculate how much tiles are in camera scope (from one end of camera to other)

Lets say your camera sees 10 x tiles .
in camera script you would move it in update function

Code (CSharp):

1. transform.position = new Vector3(startVector, endVector, time);
2.  

in unity manual is good example how to setup start, end vector and time.

Hope it helps

 

Thanks! I will see is that will work
