Well, everyone made 3D stuff with parallax effect by cloning an actor. And uses so much actors active that may slower the perfomance.
Here, i made it using 2 actors only...both of them are canvas. First canvas is used to draw the room using the parallax effect, the second canvas is used to add zoom in/out effect. So that you can scroll the view at 4 direction: left, right, front, and back. Make it more real to 3D.
Enjoy
