Well, I never saw or used a one-way door in reach so I don't know what they're like, but based on what you guys have said, they pull you through slightly. If you had a one way door a little bit above the floor, causing it to constantly want to pull you towards the floor, would you be unable to jump, jump less, or just jump the same?
interesting idea, but i think the push or pull of the shield door wouldn't be strong enough to push you into the wall/object.
Yeah it will act as a sticky floor. It has some very interesting propeties which map makers and switch makers will love alike.
