How can I get a scene to scroll left or right by clicking buttons so the suer can "walk around" the scene for example I have seen this done on a site like

where the mouse movements reveal the flash movie.

What I want to do is simpler. Just "pan" left or right by onclicking L/R arrow buttons.

I think what I need to do is create the whole scene and somehow make it move
left or right with button functions.

any suggestions?

there is also something I'm seeing done which is called a "parallax" effect going on there too which looks great. I think this is done by assigning a different "velocity" to a background layer.(I don't need to figure that out now
I'm just really impressed with it.)
