I thought it had been a while since I had posted about some of the projects I am working on. At present I am working on some 2d Scroller games in XNA, both of them are clones of original games. The main purpose though of these games was to play around with parallax scrolling games and getting some base classes together.
The first project is a clone of the original parallax scroller Moon Patrol....
And the Second is a clone of the game Choplifter....
Each of these two games use the parallax scrolling for the background, the first uses the scroller to show the distance travelled along the surface and it increases as the speed of the game increases, but it only goes one way, right to left.. The second game uses the parallax scoller in a different way, it has been configured to move in the same directon that the player is traveling in, the player moves right the scroller follows and same to the left.
Parallax scrolling is a special scrolling technique in computer graphics. In this pseudo-3D technique, background images move by the "camera" slower than foreground images, creating an illusion of depth in a 2D video game and adding to the immersion. The technique grew out of the multiplane camera technique used in traditional animation since the 1940s.

I know that I need to do some more work on the artwork, and tidy up the code, but I will be releasing the source code to the projects so that others can see what I have done.
