WayPoint Help

OK, well it's not really a way-point I'm after. I want my Zombie character to go slide over to the Enemy's house. the only thing is i want to be able to move the house around. So I'm asking if there's anyway to just tell my zombie to go to the house with out having to calculate the X's and Y's of it all.

P.S. I'm basically just looking for the simplest way of doing it.

Thanks allot

I don't know of any other method without giving it the X & Y coords. X, Y, & Z in some cases are the only way to know the location of objects on the stage.

Thanks alot
