Game Physics, Curved Ground

Hey Guys,

I’ve been working on a flash game (sidescrolling platformer)for a few weeks now and was wondering how I can get my character (on a bike) to move up a curved bit of ground. At the moment he moves up it staying horizontal all the time but I want him to look as if he’s actually moving up it so in theory the wheels follow the ground. I suppose I would like the finished product to be similar to the popular flash game ‘Happy Wheels’!

Thank you, I would really appreciate any help :slight_smile:
