camera movement

Questions & Answers
1

I am trying to make a script that allows the camera to move forward and backwards only when u put two fingers on the touchscreen and if you slide the fingers forward the camera will go forward and if you slide them backwards the camera will go back within a certain limit. How should i do this? (I am developing for iphone)

I would look at the Input.Touch interface in the Script references.
http://unity3d.com/support/documentation/ScriptReference/Input.GetTouch.html

There are some examples showing how to use them.

Once you understand how Input.GetTouch works, you should be able to translate the deltatouch values into camera translations.
