Hey Andrew,
Thanks for the reply. The game I am trying to make is a little different from Asteroids and Galaga.
The difference is that the camera seems to be moving forward in a constant velocity through a predefined level - with a lot of environment beneath. At all times the player can maneuver within the view port (which is constantly moving forward) but can never go back.
Here is an example of the game IFighter 1945 that demonstrates the camera effect I am trying to implement
Thanks again for the tips,
B
