I'm trying to make the lights seen in portal 2 beginning to come out of the wall and light up. Can anyone direct me to a tutorial or explaining to me how to make these work. I'm really stumped on making these work. I'm really new to map making with hammer. I have looked at the tutorial I'm just not understanding the explanation. I'm using "Value Portal 2 Authorizing tool beta"

Never Mind starting to figure it out.

Your question doesn't even make sense.

He's talking about the animated version of the wall lamps from the extended relaxation chamber. They retract into the walls. From the sound of it, he's worked out how to reverse the animation and set up a toggleable light source.
