Andrew11, it’s not good form to post your email address and ask for people to contact you outside the forum. Besides, you’ll attract spambots. Makes people think you are here to poach talent, instead of to learn and share.
Not your fault, you probably didn’t know any better. Now you do.
Anyway, here’s a racetrack tutorialyou might be interested in, to get your game started. It’s an oldie, so some of the keystroke instructions might have changed a bit, so if you run into problems, post back and ask questions.
Roubal wrote a tutorial on rigging a car to run on a path and said something at the time about modifying it for motorcycles, but I haven’t seen that anywhere (otoh, I haven’t looked.)
Welcome to BlenderArtists
PS, we used to flame people who started their stay here with “I’m completely ignorant, but I want you guys to make a game for me.” Perhaps you avoided this by posting in Artwork instead of the Games forum, where this post belongs. Perhaps its just that we’re getting tired of flaming noobs. If you take a look around, there are some projects you could join, rather than starting a new one.
