[quote:151ffk68]Another example would be to simply be running on a 2D plane with a floor and a ceiling, jump up, have the character flip upside down and then be running on the ceiling.
This you can already do. In fact, I'm making a game where you can do exactly that.
As for the 360 degree gravity, you might try physics. But yeah, as SpongeBrain said making your own custom movement with events would probably be the best way to go.
@SpongeBrain: I don't think it would really be feasible to add 360 gravity to the existing platform behavior, the way it works currently is just not compatible at all. David would probably have to rewrite the behavior from scratch.
Though if David is still working on his Custom Movement behavior (or whatever it's called) then it would be a lot easier to make a 360 degree gravity platform whatever blah blah.
