How do I scroll the game layout, Mario Bros style?

My intended title is going to be a Mario Bros platformer with coins, junk like that.

But I have no idea how to get the camera to scroll. I've read a couple tutorials and posts here about making overlapping blank sprites for zoning, but I don't want that, I just want a scrolling camera with a stationary hub and junk. I can always ask about the hub later.

I didn't understand completely, but as per mario like scrolling give your player "Scroll To" behaviour and that will do.

I'll try it!
