Need help changing 3rd person camera

I would like to alter how walking backwards works. I would like to change it to keep the character and camera looking forward but move the camera, character controller, and character backward. Looking at the 3rd person camera code it uses the horizontal axis controlled by the up and down arrows to control moving forward or backward. How would I best change this to meet the above requirement? Any help in the right direction would be appreciated.

The code base I started with is the springfollowcamera.js script and thirdpersoncontroller.js.

Thanks!

There is an example project in the resource section that deals with Camera Relative (character can turn to the camera) and Player Relative (players back stays toward camera) controls. Its the Penelope tutorial that has these camera control scripts. Look through them to see how its done, or check this vid out…http://gameprefabs.com/products/show/62
