This is my first post at this section (XNA and game development). I'm trying to get something like the below image. As you can see, there's a highway and inside of it, there'll be some objects moving (millisecond). I guess the streeth behavierstreet behavior is like a pipeline. When the highway loads an object, it appears at the begginingbeginning and it'll be moving through the highwarehighway until it arrives in the anotherother extreme of the highway.
My main problem is, how can I do to move several objects only inside of the highway?
Thanks in advance.
