Yeah that is where I am stuck. Originally I thought about having invisible objects acting as scrollable areas around the character but the character wont interact with them on a none scrolling layer even though when I set them to visible, they are clearly there.
It's cool working this one out though as I have discovered other methods of scrolling. 
One thing Nimtrix, I don't understand this "lerp" command, can you roughly explain it to me. 
Thanks again!
