I am using the LibGDX framework. I'm not using Scene2D but I want to implement my own "scrolling UI". This is only what I could think of (see image below):

two cameras

I will make the 2nd camera look at very far coordinates (and draw the UI stuff there) and have it (within the blue box) receive its own input. But I think this is not possible with LibGDX, since if you set the size of the camera you are like setting the viewport and how big it views the world and not how big the viewport is. I mean you can't set the size of the camera of something like 50px width and height and have it place on the center. If you setPosition, you are setting it to where it looks at and not where it is placed in the 2D space. I'm trying to explain it clearly and I hope it is clear.
