What's a threadmilling system?

I have tryed to move the camera only with the x axis. Or do you mean the camera should move along a curve(Path)?

When the camera is moving, how can i get to work, that the ship moving with the camera, but can fly in every direction without loss of speed? (f.e. the camera moves to the right, but when the ship moves to the left, it get very slow) The the next problem is, i can't set the "fly area" to the screen size.

I realize that i have nothing done with gamestudio for a long time. How can i forgot everything? It's sad but true.
