bge reflections

Hello , i’m having problem with reflections in game engine. I’m using Martin Upitis method and script when one camera captures and gets object list which is projected on the floor as inverted and then all thing is displayed on active camera.
the problem is that i can’t set it to the multiple objects, is there a way to do it ? i want to set some reflections on doors and TV. https://www.youtube.com/watch?v=jB9DQycOR8g
