Yes I already have such a system with a menu. But now I am looking for making it more complex. I know everything how I'd do it. I only don't know how i could make the curves. because I thought I'd split one curve up in a couple of small pieces. But I don't know how to calculate the position, pan and such things.
Sorry but I understand the basics and the things from the AUM. If you look on my Sites then you know that I even have a prototype game with full level-editor and things. All I wanted to know if someone already has done such a thing with streets and still hase the algorithm for a such calculation.
But as it seems that they don't I will do it myself. Thanks anyway
