I am trying to make a simulation that allows a user to draw a track, and then drop a sprite on it that naturally follows the path that the ball moves. Like a rollercoaster where the passengers have no seatbelts, I want the ball to leave the track if it goes too fast over a hump, or leave the track if the ball is moving too slowly on an inverted section.
I have made some progress thanks to reading some clever posts by R0j0hound, but I am stuck on making the ball follow a loop.
Any advice you can offer would be greatly appreciated.
