I've been trying everything to make a one way ladder that goes from the bottom. It's got to be perfect, no jumping required to get to the top, no layer 6 infront of jack, ect. Just like a good 'ol ladder climb with nothing making it look bad, just the fact that you can't go back down, Jack just ducks, and doesn't go down. I've been at this awhile, never figured this out. Help? ::)
