( The following may seem rude, but I only want to give some helpful advice) Jumping in an RM2k3 game is impractical and pointless. Player encounters a log, player presses button, game continues. But for you, the gamemaker it's the above problems. Why put yourself through such hell for something that won't add to character depth, story, or your combat system? Just because you can do it, doesn't mean you should.
