Keep actor on scrolling screen

I have an invisible actor which slowly moves up the screen in which the camera follows. I also have another actor which is free to move about the screen. I want to constrain the free moving actor within the screen and around the invisible actor. Right now I have the second actor constrained within the 0-768 range on the x axis so he can't move outside of the screen. I'm having trouble figuring out the y axis though.

I made two real game attributes to constrain the invisible actor. game.CamControllerX constrained to self.positionx game.CamControllerY constrained to self.positiony My understanding is that this keeps track of it's x and y coordinates at all times. Now I'm just trying to figure out how to make it so that the second actor, the free moving one, will be constrained on the y axis around the invisible one so that when the invisible one is moving the camera, your free moving actor won't fall behind the camera. Suggestions?
