I would like to make a game similiar to star fox (an on-rail shooter) for a few friends of mine. But, I can't figure out how to set the rails. I saw a video on youtube of someone doing a path for a character to follow, but you can't move side to side or up and down.
I did see a couple games where I did see a couple games where you can move around the screen like what I want, but no explanation was given on how they achieved that.
So, my question is, how do you define a path where you can move around the screen?
Here's an example of what I want to do: http://www.youtube.com/watch?v=rjezvmnXzPo
