still the camera is not movin........ help needed

Enclose your code in brackets to start with, it is very hard to read. I'm going to wrap my camera code into a scene node, maybe that will help you. Firstly, I wouldn't inherit from ISceneNodeAnimator and IEventReceiver, I would inherit from ICameraSceneNode. Check out the way that ICameraMayaSceneNode scrolls whilst holding the RMB, it should help you work out your code. If I do it before you manage to work it out I will post it for you.
